Objective: The purpose of the present study was to identify the fermenting and non-fermenting gram negative bacteria from the tertiary care hospital.Methods: The conventional method of identification by biochemical analysis and antibiotic susceptibility test was performed by Kirby-Bauer disc diffusion method. Furthermore, analysis of microbes was done by Vitek-2.Results: 424strains of lactose fermenting and non-lactose fermenting gram negative bacilli were isolated from 3097 clinical samples. From the total lactose fermenting bacteria Escherichia coli was the predominant isolate accounting for 50.94% specimens, followed by Klebsiella pneumonia 27.59% and Enterobacter 0.47%. From the total non-lactose fermenting gram negative bacilli Acinetobacter baumannii was the predominant isolate accounting for 12.73% specimens followed by Pseudomonas aeroginosa 6.13%, other isolates were Stenotrophomonas maltophilia 1.17% , Burkholderia cepacia 0.94%. In the present study male were more infected than female. The study also showed that lactose fermenting bacteria were more infectious than non lactose-fermenting bacteria and isolates were from urine samples.Conclusion: Both Non-Lactose Fermenting Gram Negative Bacilli and Lactose Fermenting Gram Negative Bacilli were found to be major contaminants, and are important pathogenic bacteria causing wide range of infections in the tertiary care hospital.Keywords: Lactose fermenting gram negative bacteria, Vitek-2, Tertiary Care Hospital, Kirby-Bauer Disc Diffusion, Lactose non-fermenting gram negative bacteria

Objective: Imipenem resistant gram-negative bacteria (GNB) have become a major public health concern worldwide, including Bangladesh. The present study was performed to determine the frequency of imipenem resistant gram-negative bacteria (GNB), their antimicrobial susceptibility pattern. Materials and Methods: A total of three hundred and fifty clinical samples were collected from Bangladesh Institute of Health Sciences hospital (BIHS), Dhaka, Bangladesh, over a period of 12 months. Among 350 samples, 171 (48.86%) were from indoor patients, and 179 (51.14%) were from outdoor patients. The pathogens were isolated and identified by conventional methods and were screened for antibiotic susceptibility using the Kirby–Bauer disc diffusion method, including imipenem discs. A Chi-square test was employed for statistical analysis. Results and Discussion: Out of 350 clinical isolates, 246 showed resistance to imipenem (70.28%). Almost all of the imipenem resistant gram-negative bacteria showed the highest resistant pattern to cefepime (88.57%), amoxicillin (88.29%), cephalosporin (88.14%), cefoxitin (86%), tetracycline (84.42%), and the majority were resistant to levofloxacin (70.85%), doxycycline (70.57%), netilmicin (59.71%). But cotrimoxazole (13.42%) and tigecycline (11.43%) showed a lower resistance pattern. Statistical analysis exhibited imipenem resistant gram-negative isolates most commonly found in pus and urine samples, while Klebsiella spp (30.49%), Pseudomonas spp (26.83%) and E. coli (23.17%) were the most predominant pathogens. Conclusion: This is a retrospective study which study indicates a noteworthy rate of clinical isolates were imipenem resistant gram-negative bacteria in a well-defined tertiary care hospital, and most of these bacteria were also multidrug-resistant.

Sepsis continues to have a substantial mortality and morbidity despite advances in the diagnosis and management of this condition. We retrospectively analysed hospital charts of patients diagnosed to have sepsis between January 2002 and June 2003. Demographic characteristics of patients, microbiological findings and predictors of survival were evaluated. Sixty-nine sepsis episodes that occurred in 63 patients were analysed. The most common underlying diseases were hypertension, malignancies and diabetes mellitus. Renal insufficiency, respiratory distress and disseminated intravascular coagulation developed in 52·2, 30·4 and 30·4% of the episodes respectively; 47·7% of the blood cultures yielded an organism. Gram-negative bacteria were the predominant microorganisms (65·9%). Fifty-five patients (87·3%) died. Mechanical ventilation and underlying renal disease were significant determinants of mortality. In conclusion, Gram-negative bacteria remain the major pathogens in sepsis. The mortality remains very high, and a change in the clinical approach to the septic patient should be employed to improve the outcome.

Methicillin-resistant coagulase-negative staphylococci (MR-CoNS) associated infection is a growing concern in healthcare settings now a day. MR-CoNS are the main infectious agents of the hospital acquired infection. Clinical staffs to patients transmission of resistant strains have caused a rapid increase in the prevalence of antimicrobial resistance in recent years. Growing rate of antimicrobial resistant against available antibiotics of MR-CoNS is a developing problem in low income or lower middle income counties. This study was conducted to determine the occurrence MR-CoNS isolated from different clinical staffs of tertiary care hospital. This prospective study conducted in clinical staffs, nasal swab were collected from all the participants. Screening of CoNS were done on the basis of cultural, morphological and biochemical tests, identification and AST analysis done by VITEK-2 automated system. Methicillin resistance pattern was checked by VITEK-2 and Kirby-Bauer disc diffusion method according to CLSI guideline. A total of 129 nasal swab samples were collected from clinical staffs, of which n=81 isolates (85.6%) were CoNS. Among n=81 CoNS, (48.12%) , (41.97%) , (7.4%) and (2.4%) were reported. Out of n=81 CoNS isolates, n=26 were conformed as MR-CoNS. Maximum methicillin resistance were reported in 53.48% (14/26), 42.30% (11/26), 3.84% (1/26) and 0% (0/26). Theoccurrence rate of MR-CoNS are higher (20.6%) in the healthcare workers and most of the methicillin resistant-CoNS isolates shows high level of resistance against widely used antibiotics but all the isolates susceptible against vancomycin.

Objective: Chronic osteomyelitis is the infection and inflammation of the bone. Inappropriate use of antibiotics and multidrug resistance has raised the morbidity and mortality rate in chronic osteomyelitis. This study aims to determine the bacterial profile and antimicrobial susceptibility patterns of chronic osteomyelitis with special mention to various resistant mechanisms. Methods: The study is a prospective design. Hundred (100) clinically diagnosed cases of chronic osteomyelitis of all age group and both sex admitted in a tertiary care hospital at central India, in one year were included. Samples like pus, sinus discharge or exudates were collected aseptically and sent for microbiological investigation. Antimicrobial susceptibility of bacterial isolates to the commonly used antibiotics was done by using modified Kirby Bauer disc diffusion method. Results: The aerobic bacteriological study of chronic osteomyelitis showed Staphylococcus aureus is being continued to be major etiological agent followed by Pseudomonas aeruginosa and Staphylococcus epidermidis. Gram-positive isolates were sensitive to linezolid, teicoplanin while gram-negative isolates were sensitive to colistin, ciprofloxacin in the majority. The disease occurs mostly due to traumatic injuries commonly affecting the middle age group. In present study prevalence of methicillin-resistant Staphylococci aureus and β Lactamase producing (ESBL, Amp-C and MBL) gram-negative bacilli is found to be on the higher side. Conclusion: It has been the major cause of morbidity for a long time. The emerging multidrug-resistant strain is a major concern for the treatment. Identification of causative isolates and using a judicious selection of antibiotics will help the clinician in starting the empirical treatment accordingly would limit the multidrug resistance strains in the hospital as well as the community.
