Episodes of diarrhea, glomerulonephritis, and polyarthritis sometimes also occur. Antimonial treatment is not very effective and recurrences are frequent (Barriga, 1997). Severity of clinical symptoms does not appear to be related to parasite load, as very heavily parasitized dogs may have mild symptomatology. In Brazil, more than 30% of infected dogs had no apparent clinical symptoms (Hipolito et al. Infection in the fox Lycalopex vetulus in northeast Brazil is similar to that of dogs. Some animals may have clinically inapparent infections, while others manifest different forms of the disease, including very serious and even fatal cases. Source of Infection and Mode of Transmission: the epidemiology of the disease varies from region to region and from one area to another. In the Americas, the reservoirs of visceral leishmaniasis are dogs and the wild canids. The infection is spread among canids and from these animals to man by the bite of the phlebotomine fly Lutzomyia longipalpis. The epidemic significance of the man-dog link seems to vary from area to area; while some authors have found no correlation between the prevalence in humans and in dogs (Paranhos-Silva et al. The most important endemic area in the Americas is in northeastern Brazil; the main foci are distributed across a semiarid region that is subject to prolonged droughts. The disease is basically rural, with a few cases occurring in populations or places on the outskirts of cities. The largest concentration of cases occurs in foothill areas or in mountain valleys, where the disease is endemic with periodic epidemic outbreaks. In the flatlands, on the other hand, cases are sporadic and occur primarily in the most humid areas, near rivers. In Brazil, the geographic distribution of the disease coincides with that of the vector. The main, and possibly the only, vector in the endemic area of northeastern Brazil is the phlebotomine L. Dogs are an especially suitable reservoir because they offer the vector direct access to the parasitized macrophages of their cutaneous lesions. In studies conducted in Ceara, Brazil, parasites were detected in the skin of 77. In addition, humans have been found to have a lesser number of parasites in their skin than dogs. Amastigotes are scarce in human skin and only rarely serve as a source of infection for the vector. A wild host of visceral leishmaniasis in northeastern Brazil is the fox Lycalopex vetulus, which often comes near houses to hunt chickens. In the tropical rain forest region of the lower Amazon, such as the state of Para, where the number of cases in humans and domestic dogs is low, the reservoir of the parasite is suspected to be a wild canid. In the Mediterranean basin, dogs are also the principal reservoir, while several species of the genus Phlebotomus serve as vectors. In the Middle East, jackals and dogs are the hosts and the main sources of infection for phlebotomines. In India, by contrast, no dogs or other animals have been found to be infected, and man is the main reservoir (Bhattacharya and Ghosh, 1983). When the campaign was discontinued, Bihar experienced an epidemic resurgence of kalaazar (see Geographic Distribution and Occurrence in Man). In the absence of an animal reservoir, subclinical human infections may play an important role in maintaining the disease (Manson and Apted, 1982). Person-to-person transmission takes place by means of Phlebotomus argentipes, an eminently anthropophilic insect which feeds solely on humans. In India, the number of parasites circulating in human blood was found to be sufficient to infect the vector. Transmission occurs inside houses, which constitute microfoci of infection (Manson and Apted, 1982). In Sudan, the infection has been found in wild rodents of the species Arvicanthis niloticus and Acomys albigena, domestic rats Rattus rattus, and carnivores Felis philippsi and Genetta sangalensis. It is believed that rodents are the primary hosts for the agent and that carnivores are secondary reservoirs. Humans develop parasitemia and, under epidemic conditions, can be a source of infection for the vectors. Numerous investigators believe that visceral leishmaniasis was originally an infection that circulated enzootically among wild animals (canids and perhaps rodents), and that later, domestic dogs were included in its cycle; eventually, the disease became an infection transmitted between humans without the intervention of an animal reservoir, as is the case of kala-azar in India. In the Americas, it has been suggested that the fox Cerdocyon thous, which becomes infected without becoming ill, could have been the original reservoir. However, more research is needed, especially concerning rate of infection, to confirm that this animal is the original reservoir (Lainson, 1983). Diagnosis: Confirmation of visceral leishmaniasis is made by identifying the parasite. In the form of visceral leishmaniasis that occurs in the Americas, the parasite can rarely be seen in films of peripheral blood; however, this technique can yield positive results for kala-azar in India. The most sensitive procedure (98% positivity) is splenic aspiration, but this technique entails high risk, especially in patients with anemia and clotting problems. In the early stages of the disease, when parasites are scarce, culture in Novy-McNeal-Nicolle or another appropriate medium or intraperitoneal inoculation in hamsters can be used. Although blood samples on filter paper can be used, the sensitivity of the test increases if lymph node or bone marrow aspirates are used (Osman et al. In dogs and other canids, the parasites can be observed or isolated by culture or hamster inoculation, using material from cutaneous lesions or the viscera of dead animals. When the usual methods for detecting the parasite do not produce results or the media needed to perform them are not available, immunologic tests are generally used. The direct agglutination test to detect visceral leishmaniasis has a sensitivity of over 99% and a specificity of 96% if the appropriate dilution is used (Boelaert et al. However, the reproducibility of the test was not entirely satisfactory (Mauricio et al. Control: Leishmaniasis control measures are directed against the vectors and reservoirs. The incidence of kala-azar in India decreased markedly in the wake of the antimalaria campaign, and the infection has virtually disappeared from the districts that were sprayed. Spraying should not be limited to dwellings, but should also be done around animal dens, stone walls, refuse dumps, and other places where the vector breeds. In regions in which the infection is of zoonotic origin, it is considered important to systematically eliminate infected dogs and, to the extent possible, control the fox population. On the Greek island of Crete, destroying infected dogs brought down the incidence of the disease in humans significantly. However, vigorous campaigns in northeastern Brazil have not borne out the effectiveness of controlling dog populations and experimental studies have shown that eliminating dogs does not reduce the incidence of human infection (Dietze et al. In regions in which the infection is of human origin, human cases should be detected and treated. Although vaccination against leishmaniasis is considered impractical because the infection inhibits immunity, experimental studies have demonstrated that partial protection was achieved in mice injected with L. The next most effective control method is reduction of host susceptibility through improved nutrition for children and vaccination of people and dogs. Elimination or treatment of dogs that serve as reservoirs is considerably less effective than either of these methods (Dye, 1996).

Further evidence incriminating the fox Cerdocyon thous (L) as a reservoir of Amazonian visceral leishmaniasis. Etiology: the agents of this disease are cercariae of avian schistosomes (mainly species of the genera Australobilharzia, Bilharziella, Gigantobilharzia, Microbilharzia, Ornithobilharzia, and Trichobilharzia) or of nonhuman mammals (species of the genera Heterobilharzia, Orientobilharzia, Schistosoma, and Schistosomatium). Man is an aberrant host for these species and does not sustain the development of the parasite beyond its cutaneous site. Although there are differences in the details, all schistosomes share basically the same life cycle (see the chapter on Schistosomiasis). When the egg reaches the water, the miracidium is released and swims in search of an appropriate intermediate host, which is usually a snail belonging to Bulineus, Lymnaea, Nassarius, Physa, Planorbis, Stagnicola, or another genus. The miracidia penetrate the body of the mollusk and invade the digestive gland (hepatopancreas), where they develop into another pre-adult stage, the sporocyst. Another pre-adult stage forms within the sporocyst, the redia, which, in turn, gives rise to yet another pre-adult stage, the cercaria. After several weeks, the fork-tailed cercariae mature and leave the snail, swimming in search of a definitive host. Their infectivity decreases quickly and they generally die if they fail to find a host within 24 hours. The schistosomula penetrate the blood or lymph vessels and travel to the lungs, where they remain for several days. In man, the cercariae are usually destroyed in the skin before reaching the circulatory system. Of a group of 28 Dutch tourists who became infected with human schistosomes in Mali (West Africa), 10 (36%) had symptoms of cercarial dermatitis (Visser et al. Geographic Distribution and Occurrence: Cercarial dermatitis occurs worldwide in all climates, and in all places where people, through their recreational or occupational activities, come into contact with contaminated waters in rivers, lakes, floodlands, irrigation canals, and oceans near the coast. Swimmers, clam-diggers, washerwomen, fishermen, and rice-field workers are the groups most likely to be exposed. As a precise diagnosis is difficult, many cases are probably never recognized as cercarial dermatitis. The Disease in Man: Cercarial dermatitis is basically a defense reaction to an aberrant parasite, which the host almost always successfully destroys, but which causes allergic sensitization. When a person is exposed to cercariae for the first time, the symptomatology is usually mild and may pass unnoticed. Between 10 and 30 minutes after exposure, the affected person feels a transitory itching and macules appear but vanish within 10 to 24 hours. After 5 to 14 days, small papules appear, accompanied by temporary itching where the macules had been. As no immunologic reactions are expected in the first few days of a primary infection and the cercariae are destroyed within approximately 30 minutes in the malpighian layer, the symptoms that occur in the first few days are presumed to be the result of the damage caused by the parasite and the chemical substances it releases. The clinical manifestations that appear towards the end of the first week suggest an allergic reaction to the dead parasite.

Possible protective effect of repeated low dose exposure leading to enhanced immunity. Dogs & Cats reported prevalence of 5 10% but this is likely an underestimate Livestock prevalence of up to 100% in calves infections usually occur in calves less than 3 weeks of age and may occur in conjunction with other agents of neonatal diarrhea (rotavirus, coronavirus and E. Morphology & Life cycle Infective stages (transmission) sporulated oocyst, tissue cyst (bradyzoites), tachyzoites. Definitive host (cats & other felids) Ingests tissue cysts (bradyzoites) or sporulated oocysts which excyst within gut and release infective stages (bradyzoites and sporozoites) which invade intestinal epithelial cells of small intestine and undergo merogony (asexual reproduction to produce merozoites). Merozoites then penetrate other intestinal cells and develop into gametocytes (male or female). Fusion of male gametocyte with female gametocyte produces unsporulated oocyst which is extruded into lumen of intestine and evacuated with fecal material. Sporogony maturation of the oocyst in the environment (1-5 days) to infective stage (sporulated oocyst). Tachyzoites then re-infect more cells which results in a multiplication of the infection prior to disseminating systemically to invade all tissues. Tachyzoite multiplication continues until the host immune system responds which alters development towards the formation of tissue cysts containing slowly dividing bradyzoites which remain dormant for the life of the host. Toxoplasma gondii Feline Life Cycle Dubey (1998) International Journal for Parasitology 28: 1019-1024. Shedding is typically for 1-2 weeks therefore, fecal flotation is considered of little valuefi Still recommended that potential exposure to oocysts (infected intermediate hosts) be minimized. It has been proposed that an intermediate in the reduction of metronidazole, produced only in anaerobic bacteria and protozoa is bound to deoxyribonucleic acid and electron-transport proteins, inhibits subsequent nucleic acid synthesis. In patients with mixed aerobic-anaerobic infections appropriate concomitant antibiotics active against the aerobic component should be considered. Known or previously unrecognized moniliasis may present more prominent symptoms after treatment with metronidazole. Patients should be warned about the potential for confusion, dizziness, hallucinations, convulsions or transient visual disorders, and advised not to drive or operate machinery if these symptoms occur. Metronidazole should be used with caution in patients with active or chronic severe peripheral and central nervous system diseases due to the risk of neurological aggravation. Patients should be advised not to take alcohol or alcohol-containing medicines during metronidazole therapy and for at least one day afterwards because of the possibility of a disulfiram-like (Antabuse effect) reaction. Cases of severe hepatotoxicity/acute hepatic failure, including cases with a fatal outcome, with very rapid onset after treatment initiation, in patients with Cockayne syndrome have been reported with products containing metronidazole for systemic use. In this population, metronidazole should therefore only be used after careful benefit-risk assessment and only if no alternative treatment is available. Liver function tests must be performed just prior to the start of therapy, throughout and after end of treatment until liver function is within normal ranges, or until the baseline values are reached. If the liver function tests become markedly elevated during treatment, the drug should be discontinued. If the infection is not improved following 2 treatment courses of 10 days, cultures should be obtained to guide further treatment. Culture and susceptibility studies should be performed to determine the causative organisms and their susceptibility to metronidazole. Based on clinical judgment and anticipated bacteriological findings, therapy may be started while awaiting the results of these tests. However, modification of the treatment may be necessary once these results become available. Metronidazole has also been used in the treatment of a small number of cases of brain or lung infections (some with abscesses) caused by anaerobic bacteria. A rare case of reversible but profound neurological deterioration has been reported following a single oral dose of metronidazole; it is therefore advisable that a patient taking metronidazole for the first time not be left unattended for a period of two hours. The appearance of abnormal neurologic signs demands prompt discontinuation of metronidazole therapy and, when severe, immediate medical attention. Activated charcoal may be administered to aid in the removal of unabsorbed drug, if no more than two or three hours have elapsed since administration of the drug. If for compelling reasons, metronidazole must be administered longer than the usually recommended duration, it is recommended that patients should be monitored for adverse reactions such as peripheral or central neuropathy (such as paresthesia, ataxia, dizziness, convulsive seizures). Patients with severe hepatic disease (including hepatic encephalopathy) metabolize metronidazole slowly with resultant accumulation of metronidazole and its metabolites in the plasma. Administration of solutions containing sodium ions may result in sodium retention. Care should be taken when administering metronidazole injection to patients receiving corticosteroids or to those predisposed to edema. Hematological tests, especially regular total and differential leukocyte counts are advised if administration for more than 10 days or a second course of therapy is considered to be necessary. Carcinogenesis, Mutagenesis, Impairment of Fertility Metronidazole has been shown to be carcinogenic in the mouse and in the rat. In studies conducted in mammalian cells in vitro as well as in rodent in vivo, there was inadequate evidence of mutagenic effect of metronidazole. Prominent among the effects in the mouse was the promotion of pulmonary tumorigenesis. This has been observed in all six reported studies in that species, including one study in which the animals were dosed on an intermittent schedule (administration during every fourth week only). Also, the published results of one of the mouse studies indicate an increase in the incidence of malignant lymphomas as well as pulmonary neoplasms associated with lifetime feeding of the drug. There were statistically significant increases in the incidence of various neoplasms, particularly in mammary and hepatic tumors, among female rats administered metronidazole over those noted in the concurrent female control groups. Two lifetime tumorigenicity studies in hamsters have been performed and reported to be negative. Fertility studies have been performed in mice at doses up to six times the maximum 2 recommended human oral dose (based on mg/m) and have revealed no evidence of impaired fertility. Pregnancy Metronidazole crosses the placental barrier and enters the fetal circulation rapidly. Page 6 of 31 Nursing Mothers Metronidazole is secreted in breast milk in concentrations similar to those found in plasma. This reaction appears to be due to the inhibition of the oxidation of acetaldehyde, the primary metabolite of alcohol. Busulfan: Plasma levels of busulfan may be increased by metronidazole, which may lead to severe busulfan toxicity. Serum cyclosporin and serum creatinine should be closely monitored when coadministration is necessary. Disulfiram: Administration of disulfiram and metronidazole has been associated with acute psychoses and confusion in some patients; therefore, these drugs should not be used concomitantly. Lithium: Concomitant use of lithium and metronidazole may result in lithium intoxication due to decreased renal clearance of lithium. When metronidazole must be administered to patients on lithium therapy, it may be prudent to consider tapering or discontinuing lithium temporarily when feasible. Otherwise frequent monitoring of lithium, creatinine and electrolyte levels and urine osmolality should be done. Oral anticoagulant therapy (Warfarin type): Metronidazole has been reported to potentiate the anticoagulant effect of warfarin resulting in a prolongation of prothrombin time and increased Page 7 of 31 hemorrhagic risk caused by decreased hepatic catabolism. This possible drug interaction should be considered when metronidazole is prescribed for patients on this type of anticoagulant therapy. In case of coadministration, prothrombin time should be more frequently monitored and anticoagulant therapy adjusted during treatment with metronidazole. Phenytoin or Phenobarbital: In single dose studies, metronidazole injection did not interfere with the biotransformation of diazepam, antipyrine or phenytoin in man. However, patients maintained on phenytoin were found to have toxic blood levels after oral metronidazole administration. Phenytoin concentration returned to therapeutic blood level after discontinuance of metronidazole. The metabolism of metronidazole has been reported to be increased by concurrent administration of phenobarbital or phenytoin. Vecuronium: A slight potentiation of the neuromuscular blocking activity of vecuronium has been reported in patients administered metronidazole at a dose of 15 mg/kg. Eye disorders: transient vision disorders such as diplopia, myopia, blurred vision, decreased visual acuity, changes in color vision. Ear and labyrinth disorders: hearing impairment/hearing loss (including hypoacusis, deafness, deafness neurosensory), tinnitus. Gastrointestinal disorders: diarrhea, nausea, vomiting, epigastric distress, epigastric pain, dyspepsia, constipation, coated tongue, tongue discoloration/furry tongue. General disorders and administration site conditions: Thrombophlebitis has occurred with I. Page 8 of 31 Cases of liver failure requiring liver transplant have been reported in patients treated with metronidazole in combination with other antibiotic drugs. Cases of severe hepatotoxicity/acute hepatic failure, including cases with a fatal outcome, in patients with Cockayne syndrome have been reported with products containing metronidazole. Infections and infestations: rare cases of pseudomembranous colitis have been reported. Metabolism and nutrition disorders: An antithyroid effect has been reported by some investigators but three different clinical studies failed to confirm this. Nervous system disorders: convulsive seizures, peripheral sensory neuropathy, transient ataxia, dizziness, drowsiness, insomnia, headache, aseptic meningitis. Peripheral neuropathies have been reported in a few patients on moderately high to high-dose prolonged oral treatment with metronidazole. It would appear that the occurence is not directly related to the daily dosage and that an important predisposing factor is the continuation of oral and/or I.

For areas where knowledge gaps exist, recommendations for further research are listed. The Summary of Recommendations is organized as follows: 1) recommendations for who should receive indwelling urinary catheters (or, for certain populations, alternatives to indwelling catheters); 2) recommendations for catheter insertion; 3) recommendations for catheter maintenance; 4) quality improvement programs to achieve appropriate placement, care, and removal of catheters; 5) administrative infrastructure required; and 6) surveillance strategies. The Implementation and Audit section includes a prioritization of recommendations. Intermittent catheterization is preferable to indwelling urethral or suprapubic catheters in patients with bladder emptying dysfunction. Perform hand hygiene immediately before and after insertion or any manipulation of the catheter device or site. Use sterile gloves, drape, sponges, an appropriate antiseptic or sterile solution for periurethral cleaning, and a single-use packet of lubricant jelly for insertion.
