ABSTRACT
Background: Diabetic foot lesions are a major medical, social and economic problem and are the leading cause of hospitalization for patients with diabetes worldwide. Infection sometimes leads to amputation of the infected foot if not treated promptly. The present study was conducted to isolate and identify the bacterial pathogens associated with diabetic foot ulcer and to find out its antibiotic susceptibility pattern to reduce the risk of complications. Methods: Total 100 pus samples were collected from patients having diabetic foot ulcer, during July to October 2012. Samples were processed as per standard guidelines. Results: Out of 100 pus samples, 73 (73%) yielded growth of organisms making total of 92 isolates. Out of 92 bacterial isolates, 72 were gram negative and 20 were gram positive. Pseudomonas aeruginosa 25 (27%) was most common isolate causing diabetic foot infections followed by 20 (22%) Klebsiella sp., 17 (19%) E. coli, 15 (17%) S. aureus, 6 (7%) Proteus sp. and 4(3%) Enterococci, 2 (2%) Acinetobacter sp. and 2(2%) CONS and 1(1%) Providencia. Out of 72 GNB, 50 (69.4%) were extended spectrum β lactamase (ESBL) producer. Most gram negative isolates were resistant to levofloxacin, gentamicin, ampicillin-sulbactam and gatifloxacin. All GNB were sensitive to imipenem. Out of 15 S. aureus, 9 (60%) were Methicillin Resistant Staphylococcus aureus (MRSA) and were sensitive to vancomycin and linezolid. Conclusions: Pseudomonas sp. was the most common cause of infections. Most isolates were multi drug resistance.
ABSTRACT
Background: Asymptomatic bacteriuria (ASB) refers to the presence of a bacterial isolate in urine culture in an asymptomatic person. Pregnant women with ASB are more likely to develop acute pyelonephritis in later pregnancy, postpartum urinary tract infection, hypertensive disease of pregnancy, anaemia, chronic renal failure, prematurity, low birth weight babies and prenatal death if untreated. The incidence of these can be reduced by treating ASB during pregnancy. Aims & Objective: To study the incidence of asymptomatic Bacteriuria in pregnancy. Material and Methods: Approximate 20 ml of clean catch midstream urine samples were obtained from 100 pregnant women attending the Obstetric Outpatient Department. Samples were processed as per standard guidelines. Results: Microscopic analysis of urine showed pus cells in 5 (45.45%) and Gram's stain smear showed bacteria in 9 (81.81%). Urine culture showed ASB in 11 (11%) pregnant women. Escherichia coli were found in 6 (54.55%), Klebsiella pneumoniae 3 (27.27%), Enterococcus sp. in 1 (9.09%) and Staphylococcus aureus in 1 (9.09%). Antibiotic sensitivity testing showed that all isolates were sensitive to all the antibiotics. Conclusion: Incidence of asymptomatic bacteriuria was 11% in 100 pregnant women. Microscopic analysis of all 11 urine culture positive samples showed pus cells in 5 (45.45%) and Gram's stain smear showed bacteria in 9 (81.81%). The most common bacterial isolate was Escherichia coli (54.54%), followed by Klebsiella pneumoniae (27.27%), Staphylococcus aureus (9.09%) and Enterococcus sp. (9.09%). Urine culture is necessary for screening pregnant women.
