Background: The antibiotic sensitivity pattern of uropathogenic bacteria is varied with different frequency. Objective: The purpose of the study was to determine the pattern of antibiotic sensitivity against uropathogens isolated from a tertiary care hospital of Dhaka City. Methodology: A cross-sectional study was conducted in the Department of Microbiology at Shaheed Suhrawardy Medical College, Dhaka, Bangladesh during period of January 2016 to December 2016. Among 307 consecutive urine samples were collected from patients of UTI in the microbiology laboratory. Samples were mid-stream urine specimens obtained by clean catch method received from various outpatient departments and inpatient wards were transported to the microbiology laboratory in sterile leak proof container were processed immediately. Bacteria were isolated and identified by standard laboratory procedure. Results: Of the 307 urine samples processed 170(55.4%) gave significant growth of pathogens. The prevalence of UTI is high among females (58.2%) than males (41.8%). The commonest isolates were Escherichia coli (71.2%), Pseudomonas (12.4%), Staphylococcus aureus (10.6%), Acinotobactor (4.1%) and Klebsiella (1.8%). Majority (92.4%) of (uropathogens) isolates were found to be MDR. Conclusion: The study revealed that E. coli is the predominant uropathogens of UTIs.

Background: Typhoid fever remains a public health concern in developing countries. Antibiotic therapy constitutes the mainstay of management and multidrug resistant Salmonella spp has been emerged as a major public health concern. Objective: This study was done to evaluate antimicrobial sensitivity pattern of Salmonella typhi isolated from blood in Shaheed Suhrawardy Medical College Hospital. Methods: The retrospective study was done from January 2017 to December 2017 at microbiology laboratory, Shaheed Suhrawardy Medical College. A total of 367 samples, 30 isolates of Salmonella typhi obtained from blood culture. Both the indoor and outdoor patients were enrolled in this study. Results: During one year study period, total 367 cases were enrolled and the prevalence of Salmonella typhi was 30 (8.2 %). Among them (56.1%) were male with a male to female ratio 1.27:1. The bulk (50.1%) cases were in the age group of 15-30 years, 14.4% cases were in less than 15 years and 6.5% cases were in more than 60 years of age. Regarding antibiotic sensitivity pattern, 70% strains were sensitive to amikacin, 73.33% to azithromycin, 63.33% to ceftazidime, 66.66% to ceftriaxone, 86.66% to ciprofloxacin and 70% were nalidixic acid resistant Salmonella typhi. Conclusion: Ciprofloxacin may be used to treat typhoid fever cases and Ceftriaxone, azithromycin may be used as alternative drugs if they are found susceptible in culture and sensitivity testing.

The emergence of antibiotic-resistant bacteria in human is a potential global public health concern. Profiling of antibiotic-resistant bacteria with their antimicrobial susceptibility patterns from Urinary Tract Infections (UTIs) is crucial to guide antibiotic therapy. Herein we report a detailed bacteriological and molecular analysis of Staphylococcus haemolyticus and their antibiogram typing from UTIs. A total of 100 human urine samples of patients with UTIs were collected between January and December 2019 and were subjected to the conventional characterization of bacteria using the standard protocol. Molecular characterization was performed via sequencing followed by phylogenetic analysis. All bacterial strains were examined against thirteen commonly used antibiotics for susceptibility using the Kirby-Bauer disk diffusion method. The overall prevalence of S. haemolyticus in UTI was 26% with female patients having a higher prevalence of UTI (21 out of 26 or 80.76%) than male patients (5 out of 26 or 19.24%). The isolated S. haemolyticus showed 100%, 100%, 88.46%%, 76.93%, 73.08% and 65.39% resistant to penicillin, ampicillin, amoxicillin, erythromycin, ciprofloxacin and tetracycline, respectively. Importantly, S. haemolyticus demonstrated the highest sensitivity to vancomycin (100%), followed by azithromycin (80.76%), amikacin (84.61%), gentamycin (69.23%), levofloxacin (73.08%), ceftriaxone (80.76%) and doxycycline (61.54%). Overall, six variations were noted in S. haemolyticus in which most (5/6) modifications were substitutions and one (1/6) was deletion. These findings imply that mutations in the 16S rRNA gene sequence are the dominant source for species identification and variation in the drug sensitivity pattern against the S. haemolyticus. Phylogenetic analysis of the resultant 16S rRNA indicated that the isolated S. haemolyticus in this study belonged to genus Staphylococcus, but was different from the rest of the available S. haemolyticus isolates in other countries. Multidrug-resistant pathogenic S. hemolyticus is commonly found in urine samples of UTI in human in Bangladesh, which warrants a one-health approach for controlling this emerging ailment.
