Two boys died of the severe In 1845, the boy was given a royal burial, but some people form of the disorder because the brain regions that control move thought the buried child was an imposter. Another sibling was blind and had stolen at the autopsy, and through a series of bizarre events, central nervous system degeneration. Several relatives, however, wound up, dried out, in the possession of the royal family. Genes linked closely to one another are usually inherited together when the chromosome is packaged into a gamete. The term is popularly used to mean any association L l between two events or observations. Linked genes do not assort independently and do Genes linked not produce Mendelian ratios for crosses tracking two or more genes. Understanding and using linkage as a mapping tool Self-cross helped to identify many disease-causing genes before genome sequencing became possible. Punnett first observed the unex Male gametes pected ratios indicating linkage in the early 1900s, again in pea pl PpLl ppll plants. The expected Bateson and Punnett noticed that two types of third phenotypic ratio of a dihybrid cross is 9:3:3:1. The phenotypic ratio is 3:1, the same as for a two progeny classes, ppL and P ll, were less common (the monohybrid cross. The two less common offspring classes could also be explained by a meiotic event, crossing over. Recall that crossing over is an exchange between homologs that mixes up maternal and paternal gene combinations without disturbing the sequence of genes on the chromosome (figure 5. P p P p Progeny that exhibit this mixing of maternal and pater L l I L nal alleles on a single chromosome are called recombinant. Whether alleles in a dihybrid are in cis or trans Linkage Maps is important in distinguishing recombinant from parental prog eny classes in specific crosses. They assigned genes to relative positions on chro mosomes and compared progeny class sizes to assess whether traits were linked. The traits fell into four groups because their genes are inherited together on the same chromosome. Second, the fly room investigators translated their data into actual maps depict ing positions of genes on chromosomes. Morgan wondered why Homologs the sizes of the recombinant classes varied for different genes. In 1911 Morgan proposed that the farther apart two genes are on a chromosome, the more likely they are to cross over simply because more physical distance separates them (figure 5. Then undergraduate student Alfred Sturtevant devised a way to represent the correlation between crossover P p P p frequency and the distance between genes as a linkage map. L L l l these diagrams showed the order of genes on chromosomes and the relative distances between them. These units are still Meiotic products used today to estimate genetic distance along a chromosome. The linkage between two genes may be interrupted if the sequencing of the human genome. Crossing over packages genes is inferred from the proportion of offspring from a cross recombinant groupings of the genes into gametes. Frequency of recombination is based 102 Part 2 Transmission Genetics In 1968, researcher R. Donohue was looking at chromo somes in his own white blood cells when he noticed a dark area consistently located near the centromere of one member of his A a largest chromosome pair (chromosome 1). He examined chro mosomes from several family members for the dark area, noting Genes A and B far apart; crossing over more likely also whether each family member had a blood type called Duffy. B b (Recall that blood types refer to the patterns of sugars on red blood Genes B and C close together; C c cell surfaces. Crossing over is more blood type by whether or not the chromosome had the dark area. Genes at human parents do not have hundreds of offspring, nor do they opposite ends of the same chromosome cross over often, gen produce a new generation every 10 days, getting enough infor erating a large recombinant class. Genes lying very close on mation to establish linkage relationships for us requires observ the chromosome would only rarely be separated by a cross ing the same traits in many families and pooling the results. The probability that genes on opposite ends of a chromo Today, even though we can sequence human genomes, linkage some cross over approaches the probability that, if on different remains a powerful tool to track disease-associated genes.

Similarly, more crossovers, Parental Recombinant allele allele or progeny with recombinant genotypes, configuration configuration are seen when two genes are farther apart (may approach 50%) on the same chromosome. Localizing B B genes on the X chromosome was easier Independent assortment + than doing so on the autosomes, because Meiosis a b a B X-linked traits follow an inheritance pattern that is distinct from the one all autosomal genes follow.

Suggested initial empiric antimicrobial regimens based upon patient age, immunocompetence, and previous antibiotic administration include: 1. Children >28 days of age who are normal immunocompetent patient: a) Ceftriaxone/Cefotaxime plus Vancomycin //Teicoplanin c) Consider adding an aminoglycoside (eg, gentamicin/amikacin) if possibility of genito urinary source is likely d) Consider adding piperacillin-tazobactam / clindamycin / metronidazole if possibility of gastro-intestinal source 2. Patients at increased risk of fungal infection (immunocompromised with persistent fever on broad spectrum antibiotics) or with an identified fungal source. Add the following antifungals to the antimicrobial regimen a) Liposomal Amphotericin B or b) an echinocandin (eg, caspofungin, micafungin) 5. Patients with risk factors for rickettsial infection (eg, travel to or reside in an endemic region): Add a tetracyclin antibiotic (eg, doxycycline) to the antimicrobial regimen the empiric drug choice should be in accordance with the ongoing epidemic and endemic infections eg, H1N1, methicillin resistant S. Control of the Infection Source the source of the infection should be located and treated early and aggressively. Conditions requiring debridement or drainage include necrotizing pneumonia, necrotizing fasciitis, gangrenous myonecrosis, empyema, and abscesses. If intravascular access devices are a possible source of severe sepsis or septic shock, they should be removed promptly after other vascular access has been established. Duration of antibiotic therapy for sepsis It will depend on the foci of infection, immune status of the patient and response to the antibiotics. Longer courses may be appropriate in patients who have a slow clinical response, undrainable foci of infection, bacteremia with S. Empirical coverage if suspecting gram-negative bacilli Choice should be based on local antimicrobial susceptibility and the severity of disease a fourth-generation cephalosporin, carbapenem, or b-lactam/b-lactamase combination, with or without an aminoglycoside). Fluconazole can be used in patients without azole exposure in the previous 3 months in health care settings where the risk of Candida krusei or Candida glabratainfection is very low. Antibiotic lock therapy should be used for catheter salvage; however, if antibiotic lock therapy cannot be used, systemic antibiotics should be administered through the colonized catheter.

Complicated Short term central venous or arterial catheter related blood stream infection Four to 6 weeks of antibiotic therapy should be administered to patients with persistent fungemia or bacteremia after catheter removal. The antibiotic therapy is very effective if started within 9 days after onset of symptoms to prevent rheumatic fever specially carditis. Duration for secondary prophylaxis: It depends on the presence of carditis during the acute episode. Carditis present (healed carditis or mild mitral regurgitation): continue for 10 yearsafter last attack or 25 years of age [whichever is longer] 3. Carditis present (established heart disease or following valve surgery or ballon mitral valvotomy): continue lifelong 4. Expert consultation should be sought if want to discontinue after 40 years of age instead of life-long prophylaxis as recurrence beyond this age is minimal. Risk factors for Early onset sepsis are: 0 (a) Maternal fever (Temperature > 38 C) before delivery or during labor (b) Membranes ruptured for more than 24 hours before delivery. Consider for second intra-operative dosein prolong surgery based on the choice of antibiotic used for prophylaxis. These organisms are considered resistant to all penicillins, cephalosporins and macrolides. Mupirocin local application (intranasally bid x 5 days) for eradicating nasal carriage. Daptomycin: Daptomycin is an intravenous antibiotic approved to be used for the treatment of complicated skin infections and Staphylococcus aureus bacteraemia. The acquisition of resistance to vancomycin by enterococci has seriously affected the treatment and infection control of these organisms. Linezolid may be particularly useful in patients who require oral or outpatient therapy (when intravenous therapy is undesirable), who are intolerant to glycopeptides, or who have impaired renal function. These plasmids often encode mutations which confere resistance to other broad spectrum agents including aminoglycosides, co-trimoxazole and fluoroquinolones, resulting in organism resistant to most broad spectrum antibiotics. The carbapenems (Ertapenem, Meropenem and Imipenem) are currently considered the drug of choice for serious infections caused by these pathogens. Polymyxins, tigecycline & fosfomycin are the agents with most frequent in vitro activity, but all have limitations.

These are the minimum required for diagnosis, prognosis and follow up of these infections. All attempts shall be made to send microbiological samples prior to initiating antimicrobial therapy. Rapid tests, such as Gram stain, can help determine therapeutic choices when decision on empiric therapy is required. Differentiation between contamination, colonization and infection is important to prevent overuse of antimicrobials. Use hospital guidelines based on local antibiograms when choosing antimicrobial therapy whenever possible. If alternatives to those recommended as used, reasons in the case records should be documented. Where patients are in hospital close observation is usually a better option till the diagnosis is made. Choice of antibiotics: this depends on antibiotic susceptibility of the causative organism. The choice can be based on Toxicity, Efficacy, Rapidity of action, Pharmacokinetics and Cost. Use the most effective, least toxic and least expensive antibiotic for the precise duration of time needed to cure or prevent infection. What is the clinical diagnosis and what other steps should be taken to reach diagnostic precision Which antimicrobial agents are available and active against the presumed cause of the illness Is their range of antimicrobial activity appropriate and what information is available about the likelihood of drug resistance Clinical Diagnosis: the antibiotic treatment chosen must be based on presumptive diagnosis made on some assumption regarding the nature of disease. The treating doctor may not have difficulty in choosing the appropriate antibiotic to treat a disease caused by a single microorganisms. However, diseases such as pneumonia, meningitis and urinary tract infection can be caused by spectrum of bacterial species and doctor may be wrong if he has to guess which antimicrobial agent to use. Accuracy of diagnosis should be reviewed regularly and treatment altered/stopped when microbiological results become available. Once culture reports are available, the physician should step down to the narrowest spectrum, most efficacious and most cost effective option. If there is no step down availed, the reason shall be documented and is subjected to clinical audit.
