Introduction: The incidence of Benign Prostatic Hyperplasia (BPH) or Prostatitis is increasing considerably worldwide. The Lower Urinary Tract Symptoms (LUTS) due to bacterial aetiology are one of the common factors for the complications among the patients.
Aim: To determine the bacterial agents and their antibiotic sensitivity pattern from the urine samples of patients of BPH or Prostatitis showing symptoms of LUTS.
Materials and Methods: The cross-sectional study was carried out in the Department of Microbiology of Rohilkhand Medical College and Hospital of Northern India from June 2014 to May 2015. A total of 105 urine specimens from patients of BPH and/ or Prostatitis were cultured by a semi-quantitative method. The isolated bacteria were identified by colony morphology, Gramís staining, motility and biochemical tests. Antibiotic sensitivity was done according to the CLSI 2007 guidelines by disc diffusion method. Data was analysed by SPSS and Microsoft office 2007. Proportions and percentages were used as statistical measures.
Results: The urine cultures from patients with BPH and or chronic Prostatitis, showed n=66/105 (62.85%) culture positivity. Out of 66 isolates the frequency was in following order Escherichia coli 21/66 (31.81%), Klebsiella spp 19/66 (28.78%), Staphylococcus aureus 11/66 (16.66%), Pseudomonas aeruginosa (10.60%), Proteus spp, Enterococcus spp, Acinetobacter spp and Citrobacter spp. The most susceptible 1st, 2nd and 3rd line antibiotics for Gram negative isolates were ampicillin, amikacin and tigecycline respectively. Amongst the Gram positive isolates, the susceptible 1st, 2nd and 3rd line antibiotics were cefoxitin, vancomycin, teicoplanin and linezolid. Multidrug resistance was seen in Escherichia coli (n=6), Klebsiella spp (n=7), Pseudomonas aeruginosa (n=4) and Staphylococcus aureus (n=3).
Conclusion: Based on the above findings we can say that accurate aetiology of the LUTS among the patients of BPH and/or Prostatitis is warranted to initiate the therapeutic management. Based on our study we state that the prime pathogens are E.coli, Klebsiella among Gram negative isolates and S. aureus among Gram positive. The most sensitive drugs are aminoglycosides, tetracyclines and carbepenems for Gram neagtive isolates and oxazolidinones and glycopeptides among Gram positive isolates.
