Bacteriological Evaluation

Abstract Objective: To evaluate the bacteriological features in non-struvite nephrolithiasis and in its associated urinary tract infection, and to establish the relationship between the two pathologies. Methods: The non-struvite calculi from 132 patients were aseptically extracted by percutaneous nephrolithotomy (PNL). The midstream urine and calculi were bacteriologically and biochemically processed. Results: Most calculi (78%) were located to renal pelvis, associated with hydronephrosis, the biochemical composition confirming the lack of struvite and revealing the predominance of calcium oxalate. The females presented significantly more colonized calculi (50%) than males (21.9%), with higher bacteriological diversity. There is a significant relation between the presence of colonized calculi and urinary tract infections, 24.2% of calculi and 25.8% of the urine samples presenting positive cultures. In 70.4% of cases, we found the same antibiotic resistance pattern between the pathogens isolated from calculi and urine, thus considering them identical strains. The Enterobacteriaceae represented the most predominant bacteria both from calculi (62.5%) and urine (63.6%), approximatively 30% being resistant to cephalosporins and over 50% resistant to fluoroquinolones, ampicillin and tetracycline. There were 3.8% of cases in which the calculi were colonized but the urine was sterile, the bacteria being sensitive to cephalosporins that are used as prophylaxis. Conclusions: In all the cases, the same bacterial species was found both in calculi and urine, and 70.4% of them were phenotypically identical. The resistance to the second generation cephalosporins is lower than in the case of other antibiotics, which makes them the most suitable for prophylaxis in PNL.

Pseudomonas aeruginosa is one of the most important opportunistic pathogens responsible for various types of hospital infections. High prevalence of antibiotic resistance in P. aeruginosa strains of human clinical samples cause more severe diseases for a longer period of time. The current research was done in order to study the distribution of blaIMP-1 gene among the imipenem-resistant P. aeruginosa strains isolated from burn and urinary tract infections of hospitalized patients. Two-hundred and forty-three P. aeruginosa isolates recovered from the cases of burn and urinary tract infections of inpatients and outpatients were analysis for antibiotic resistance pattern using the disk diffusion method. Then, imipenem-resistant isolates were further analyzed for distribution of blaIMP-1 gene using the PCR. Of 243 P. aeruginosa isolates, 146 strains (60.08%) were taken from outpatients and 97 strains (39.91%) were taken from inpatients. P. aeruginosa isolates harbored the highest levels of resistance against streptomycin (100%), nalidixic acid (100%), aztreonam (100%), cotrimoxazole (95.47%), ciprofloxacin (88.47%), cefotaxime (84.36%) and gentamycin (83.95%). Inpatients had a relatively higher levels of antibiotic resistance. One-hundred and twenty-one out of 126 (96.03%) imipenem-resistant P. aeruginosa isolates harbored the blaIMP-1 gene. Inpatients also had a relatively higher prevalence of blaIMP-1 gene. High prevalence of blaIMP-1 gene and also imipenemresistant P. aeruginosa are important public health issue. Clinical laboratories should consider the detection of the blaIMP-1 gene among the P. aeruginosa isolates of clinical samples.

Tract Infections

The urinary tract is the most common site of nosocomial infections accounting for more than 40% of the total number reported by acute care hospitals and affecting approximately 600,000 patients per year. Catheter Associated Urinary Tract Infection (CAUTI) defines in terms of “bacteriuria” and “urinary tract infection” frequently. Bacteriuria or funguria levels >103 colony- forming units (CFU) have been shown to be highly predictive of CAUTI, given that these levels increase to 105 CFU within 24 to 48 hours. In Indian population, catheterassociated urinary tract infection (CAUTI) is an important cause of morbidity and mortality, affecting all age groups. Biofilm is the predominant mode of growth in aquatic ecosystems and, as such, plays a central role in the pathogenesis of Catheter Associated Urinary Tract Infections (CAUTI). The present review focuses to evaluate the incidence and pattern of microbes in catheter associated urinary tract infection and provides information about the etiology of CAUTI. Most of the studies concluded that gram negative pathogen E.coli showed the highest incidence rate and other pathogens like Klebsiella pneumonia, Pseudomonas aeruginosa, and staphylococcus species also having the incidence rate in the patient having CAUTI. The antibiotic resistance pattern showed the variation in resistance and sensitivity of antibiotics against the pathogens. The present study focuses on the incidence of the microbial growth in patient having catheterization and also elucidates the antibiotic sensitivity pattern. It is necessary to determine the antibiotic resistance and sensitivity status during and after the catheterization.

Introduction. Community-acquired urinary tract infections (CAUTIs) are usually treated empirically. Geographical variations in etiologic agents and their antibiotic sensitivity patterns are common. Knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Our aim was to determine the major bacterial etiologies of CAUTIs and their antibiotic resistance patterns in a cosmopolitan area of Cameroon for comparison with prescription practices of local physicians.Methods. We performed a cross-sectional descriptive study at two main hospitals in Yaoundé, collecting a clean-catch mid-stream urine sample from 92 patients having a clinical diagnosis of UTI. The empirical antibiotherapy was noted, and identification of bacterial species was done on CLED agar; antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method.Results. A total of 55 patients had samples positive for a UTI. Ciprofloxacin and amoxicillin/clavulanic acid were the most empirically prescribed antibiotics (30.9% and 23.6%, resp.); bacterial isolates showed high prevalence of resistance to both compounds.Escherichia coli(50.9%) was the most common pathogen, followed byKlebsiella pneumoniae(16.4%). Prevalence of resistance for ciprofloxacin was higher compared to newer quinolones.Conclusions.E. coliandK. pneumoniaewere the predominant bacterial etiologies; the prevalence of resistance to commonly prescribed antibiotics was high.

Background: Analysing antibiotic susceptibility pattern of uropathogens help to overcome the therapeutic difficulties created by the rising anti-microbial resistant bacteria and guides in choosing appropriate antibiotics. Hence, we aimed at evaluating the uropathogens causing urinary tract infections and study their antibiograms.Methods: Midstream urine samples were collected, cultured and appropriate biochemical tests were performed for proper identification of urinary tract pathogens in State Referral Hospital Falkawn, Mizoram, India from 1st January to 30th June 2018.Results: The most common isolated gram-negative uropathogens were Escherichia coli (40.9%), followed by Klebsiella spp. (17.6%), Proteus spp. (10.7%) and Pseudomonas spp. (3.1%). Among gram-positive organisms Enterococcus spp. (20.1%) and Staphylococcus spp. (7.6%) were grown. Urinary tract infections were more prevalent in girls (64.8%) than boys (35.2%). High level of resistance was found to amoxycillin/ampicillin by all the organisms isolated.Conclusions: Almost all the test organisms exhibited multiple antibiotic resistance. The study identified multiple antibiotics resistance by uropathogens which were earlier used as first line of treatment of UTI in children.
