Culture and Sensitivity of Community Acquired Pathogens.
Med Channel Jan ;4(2):43-50.

The Objective of the study was to identify the bacteria causing mild to moderate infections and report their sensitivity pattern. This was a prospective, descriptive study conducted at the Pediatrics Out-Patient Department of Civil Hospital Karachi, from Ist January 1996 to 30th November 1996 in children aged 2 months to 12 years sufferingfrom mild to moderate bacterial infections. All children with such infections had an appropriate sample of discharge or pus from inflamed tissue sent for culture and sensitivity. The cultures were done both aerobically and anaerobically on blood and chocolate agar and Mcconkey`s agar. The results showed the growth of Pneumococcus in 7.14%, Staphylococcus aureus in 25.71%, Klebsiella in 28.58%, Proteus mirabilis in 8.57%, Proteus vulgaris in 4.29%, Pseuodomonas aeroginosa in 8.57% and Escherichia coli in 17.14% patients. Cotrimaxazole sensitivity was shown by 88,9% of Klebesiella (K) 25% Echerichia coli (E.C) 33.3% of Staphylococcus aureus (SA) 16.7% &50% Proteus microbilis (PM) and Vulgaris (PV) repectively. Chloromphanicol sensitivity was shown by 884.2% (K) 90% (E.C) 88.2%(SA 60% (PM) 100%(PV) and 50% Pseudomonas aerogenosa (PA). Amoxicillin sensitivity was shown by 47,4% (K) 50% (EC) 100% Strptococcus pneumonia (SP) 50% (PM) 66.7% (PV) and 50% (PA) Gentimycin sensitivity was sown by 87.5% (K) 100% (EV) 100% (PMPV) and 75% (PA). Even in community acquired infections there is a trend of increasing in-vitro resistance to commonly used antibiotics which are more reasonably priced than others.
