Urinary tract infections (UTI) are one of the most common community acquired infections and can also present with similar lower urinary tract symptoms (LUTS). Moreover, UTI can be a complication of these urological diseases. Thus, this study was conducted in patients with LUTS to find out the prevalence of uro-pathogens and their antibiotic susceptibility pattern so that appropriate antibiotics can be started on clinical suspicion of UTI. The study was conducted over a period of 12 months. Culture and susceptibility of urine specimen was done as per standard microbiological guidelines. Apart from the growth of common bacteria with their antibiogram, Methicillin-resistant Staphylococcus aureus (MRSA), high level aminoglycoside resistance (HLAR) was investigated among Enterococci, and metallo beta-lactamases(MBL) production was production was investigated among gram-negative pathogens. Out of 407 urine samples included in the study, 80 (19.6%) samples showed bacterial growth. The commonest isolate was E. coli 44 (55 %). Majority of the isolates were multidrug resistant with two E.coli strains showing pan-resistance to the first line drugs tested. Carbapenem resistance was seen in 67.2% of all gram negative isolates tested. Metallo beta-lactamases production was found to be highest among the Klebsiella isolates. Among the Enterobacterales, highest susceptibility was noted to Fosfomycin (87.7%) followed by Nitrofurantoin (62.7%). Similarly in gram positive group, highest susceptibility was again to Fosfomycin followed by Nitrofurantoin. Overall the prevalence of MDR is increasing however Fosfomycin or Nitrofurantoin, both oral antibiotics, can be the considered for starting empirical antibiotic therapy.
