With the previous knowledge on the production of ?-lactamase by the bacterial pathogens causing urinary tract infection, present study further investigated the presence of symptomatic and asymptomatic bacteriuria in female patients admitted into the Delta Medical College with suspected urinary tract infections (UTIs). The manifestation of uropathogens and their responses against locally available antibiotics (amoxicillin, 10 ?g; cephradin, 30 ?g; ciprofloxacin, 5 ?g; cotrimoxazole, 23.8 ?g; gentamicin, 10 ?g; nalidixic acid, 30 ?g) were inquired by means of conventional cultural techniques and double-disc diffusion methods, respectively. Among 110 urine samples collected from the patients with suspected UTI, 34 were found to be culture positive. Symptomatic (64.7%) and asymptomatic (36.3%) bacteriuria were noticed inside the puss cell of the UTI positive cases. Escherichia coli (73.5%) was the dominant bacteria while Klebsiella spp. (26.5%) was also exultant. Around 96% uropathogens were found to be sensitive against imipenem, and 75% against amikacin. E. coli was found to be sensitive against all of the antibiotics used, whereas Klebsiella spp. was found to be 100% resistant against nalidixic acid and cotrimoxazole.

Blood agar is needed for culture of various organisms. As sheep blood is needed for it’s preparation, many small laboratories specially those of rural areas can not prepare it due to difficulty in collection of sheep blood. So, either they do not do the culture or do it without blood agar which cause missing of some important organisms. In this study Brain heart infusion agar was used together with Blood agar to assess it’s efficacy as an alternative of Blood agar. In total 1256 various samples were cultured, on Blood agar , Brain heart Infusion agar and MacConkey agar. Out of 1256 samples 404 samples showed growth of various organisms. It was noted that all bacteria including Enterococcus sp. grew equally in blood agar and BHIA. Brain heart infusion agar can be used as a surrogate of blood agar.

Pseudomonas aeruginosa is one of the most widespread gram-negative microorganisms identified in the clinical samples and most common causes of hospital acquired infection. P. aeruginosa is affecting both indoor and outdoor patients throughout the world. Due to frequent mutation in          P. aeruginosa highly resistant strain developed rapidly. The aim of the study to determine the prevalence of P. aeruginosa species in different samples isolated from a Tertiary care Hospital as well as determination their diverse antibiotic resistance pattern. This cross-sectional study was carried out to determine in-vitro resistance pattern of P. aeruginosa isolates to common antimicrobial agents by disc diffusion method. Various clinical samples were collected from Bangladesh Health Sciences Hospital (BIHS) General Hospital, Dhaka. This research was carried out in the Department of Microbiology of Bangladesh University of Health Sciences (BUHS). Isolation, identification and antibiogram were performed for P. aeruginosa following standard microbiological laboratory procedure. A total of 218 P. aeruginosa were isolated from 3062 different clinical specimens which are statistically significant (p<0.0001). Among the highest number of P. aeruginosa were isolated from outdoor patients 140 compare to Indoor patients which are significantly higher (p <0.013). In this study Male (68.3%) are more vulnerable to P. aeruginosa infection compare to females (31.7%) which is also statistically significant. Young people (less than 35 years) were more susceptible to P. aeruginosa infection which is also statistically significant (p< 0.01). The highest number of P. aeruginosa was isolated from wound (43.12%), followed by pus (40.33%), sputum (8.71%) urine (7.80%). The maximum number of P. aeruginosa in various samples was resistant to aztreonam and co-tromoxazole followed by cephalosporins, aminoglycosides, carbapenems. The most sensitive antibiotic was colistin of followed by gentamycin and tetracycline. To control the spread of resistant bacteria, it is disparagingly vital to have stringent antibiotic guidelines. The antibiotic susceptibility pattern of P. aeruginosa requires to be continuously monitored in specialized clinical units and the results readily made available to the clinicians to minimize the resistance.
