Background:Wound infection continues to be a significant problem in clinical practice where empirical treatment of infection is required while waiting for culture report to prevent emergence of resistance. Objectives:To study the spectrum of aerobic bacterial pathogen isolated from pus samples and to determine the antimicrobial sensitivity pattern of the bacteria isolated. Method: The samples of pusreceived in Clinical Microbiology Laboratory were processed during the study period to isolate and identify bacterial pathogens as per standard bacteriologicaltechniques. Antibiotic susceptibility testing was done by Kirby Bauer disc diffusion method as per CLSI guidelines 2017. Result:Out of the total of 1474pus samples processed, 21.98% samples were culture positive. Majority of culture positive samples were from IPD patients.Predominance of gram negative bacteria (77.4%) was seen as compared to gram positive bacteria (22.60%) both in IPD and OPD samples. High level of resistance to various antimicrobials was seen among the clinical isolates. Conclusion: Emergence of antibiotic resistant strains in pus sample is a matter of concern. Therefore, knowledge of the spectrum of microorganisms causing pus discharge and its susceptibility pattern is required and this data may contribute to an effective management of cases of wound infection

Background: Nonfermentative gram negative bacilli (NFGNB) frequently considered as commensals or contaminants but the pathogenic potential of nonfermenters has been proved beyond doubt. They are resistant to commonly used antimicrobials. Aim: This study was undertaken to identify the nonfermenters isolated from various clinical samples and to know their Antibiotic sensitivity pattern. Materials and Methods: The present study was carried out on 150 strains of Nonfermenters isolated from 1200 various non repetitive clinical samples received in Department of Microbiology, NIMS Jaipur. Nonfermenters were identified using a standard protocol and their antibiotic susceptibility testing was performed with the help of the modified Bauer disc diffusion method. Results: Out of 150 nonfermenters isolated, Pseudomonas aeruginosa was the most common isolate 134 (89.33%) followed by Acinetobacter baumannii 16 (10.67%). Among all clinical samples Pus and Wound Discharge yield maximum isolates of NFGNB i.e. 54 (36%) % followed by sputum (39.0%). Most sensitive drug against NFGNB was Polymyxin-B (100%) followed by Imipenem (86 %) and Amikacin (71.33 %). Conclusion: Nonfermenters have a great potential to survive in a hospital environment so implementation of antibiotic stewardship programs and strict infection control practices will be required to prevent or slow down their emergence and spread. Keywords:  Nonfermenters,  Polymyxin-B, Pseudomonas, Acinetobacter.

Wound infection has always been a major complication of surgery and trauma. The aim of our study was to determine the bacteriology of wound infections and to study the antibiotic susceptibility pattern of the isolates. The study was conducted in tertiary care hospital, Erode. The design of the study was a prospective type. Pus swabs / specimens were collected from hospitalized patients who developed wound infections. Bacterial pathogens were identified by conventional biochemical methods according to standard microbiological techniques. Antimicrobial susceptibility was performed on Muller – Hinton agar by the standard disk diffusion method. The incidence of wound infection was more common in males (63%) than in females (37%). Out of 100 culture positive samples, 61 samples were collected from diabetic ulcer patients, 20 samples were from ulcer patients, and 19 samples were from post operative patients. Of the 100 samples (culture positive), 71% collected samples showed mono-microbial growth, 29% showed two type of microbial growth. The prevalence of S. aureus (62.87%) from different wound infections was found to be high, followed by E.coli (48.65%), Klebsiella (30.21%), Pseudomonas (22.16%). Organisms showed diversity in the sensitivity pattern towards the antibiotics tested. High level of sensitivity was observed to Imipenem, Piperacillin tazobactum and Amikacin. High level of resistance was observed to Cephalosporins and Penicillin derivatives. We concluded that the sensitivity pattern of the antibiotics is not based on the infection site but on the type of organisms. This study gives us an insight to the current state of causative pathogens and their sensitivity to different antibiotics used in tertiary care hospital, Erode. The data of this study may be used to determine trends in antimicrobial susceptibilities and to modify antibiotic policy of the Hospital.

ABSTRACT Aim: The emergence of Methicillin-resistant Staphylococcus aureus (MRSA) has posed a serious therapeutic challenge. We report the prevalence and antibiotic susceptibility pattern of MRSA in the hospitals attached to GMC, Amritsar, Punjab. Materials and Methods: The study comprised of 250 coagulase-positive staphylococci (COPS) isolated from a total of 6743 clinical specimens (like pus, blood, urine, high vaginal swab, sputum, etc.) of patients admitted in hospitals attached to Government Medical College, Amritsar from January 2008−February 2009. Routine antibiotic susceptibility testing was performed and interpreted as per standard guidelines. Methicillin resistance was detected using oxacillin and cefoxitin disc diffusion method, oxacillin screen agar method, and minimum inhibitory concentration using broth macrodilution method. Results: A total of 115 (46%) strains were found to be methicillin resistant. Multidrug resistance was observed in 73% MRSA strains. However, no strain was resistant to vancomycin. Conclusion: Regular surveillance of hospital-associated infection and monitoring of antibiotic sensitivity pattern is required to reduce MRSA prevalence.

Background: Urinary tract infections (UTIs) remain the common infections in outpatients as well as hospitalized patients. Current knowledge on antimicrobial sensitivity pattern is essential for appropriate therapy. The aim of the study is to determine the changing pattern of antibiotic sensitivity among uropathogens causing UTI. Methods: Urinary isolates from symptomatic UTI cases attending in Square hospital were processed in the Microbiology lab. Antimicrobial susceptibility testing was performed by Kirby Bauer’s disc diffusion method. Extended spectrum beta lactamase (ESBL) production was determined by double disk synergy test method. Results: Of the 200 tested sample 110 samples showed growth of pathogens among which the most prevalent were E.coli (58.18%) followed by Enterococci (13.6%). The majority (68.18%) of the isolates were from female. ESBL production was observed in 46.87% o E.coli strains and 25% of Klebsiella strains. More than 98% of the isolates are sensitive to Imipenem, Meropenem , while 86.36% are sensitive to Amikacin, 73.63% to Nitrofurantoin and 74.54% to Gentamicin. Very high rate of resistance is seen against amoxicillin (88.19%), cefixime (65.46%), cotrimoxazole (68.19%) and ceftriaxone (63.63%). E. coli showed high sensitivity to meropenem, imipenem and amikacin (100%) followed by Gentamicin (94.1%). Conclusion: The study revealed that E.coli was the predominant bacterial pathogens of UTIs. An increasing trend in the production ESBLs among UTI pathogens in the community was noted. Nitrofurantoin should be used as empirical therapy for primary, uncomplicated UTIs.

Background: Diabetes Mellitus is the most common endocrine disorder involving almost all systems of body. Untreated or poorly treated Diabetics are susceptible to develop a series of complications responsible for raised morbidity and mortality. Diabetes Mellitus has a number of long term effects on the Genitourinary system. Urinary tract infections have long been recognised as a significant problem in patients with Diabetes Mellitus.Methods: Prospective observational study. Diabetic patients with culture positive UTI were included. Gestational diabetes, Immunocompromised patients and patients with congenital renal anatomical abnormalities were excluded.Results: Authors included 211 numbers of culture positive UTI among diabetic patients. Out of which, 65 were male and 146 were female. Maximum number of patients belong to 56-65 years age group. Escherichia coli was the predominant organism isolated. Gram positive organisms showed 100% sensitivity to Vancomycin and Linezolid. Gram negative organisms showed 100% sensitivity to Polymyxin B.Conclusions: Genitourinary tract infection is not an infrequent complication seen in diabetes patients. Most common causative organism and their antibiotic sensitivity pattern should be done in tertiary care hospital for a better antibiotic policy.
