Background and Objectives: Vulvovaginal candidiasis (VVC) is one of the most frequent reasons for gynecological consul- tations. Candida albicans is responsible in the majority of cases. Lately, VVC caused by non-albicans Candida spp. (NAC), which are resistant to routinely used antifungals, is on the rise. This study was designed to determine the prevalence of Candida in patients suffering from vaginitis and to assess the predisposing factors along with identification of Candida species and evaluation of their susceptibility profile. Materials and Methods: High vaginal swabs were collected from 225 women. Sample processing consisted of Gram stain and culture onto Sabouraud’s dextrose agar and HiChrom Candida Differential agar. Isolates were identified and speciated using VITEK2 Compact System. Susceptibility testing was done using VITEK2 AST-Y S08 cards and disc diffusion. Results: Candida spp. were isolated from 94 (41.8%) of the cases. C. albicans was the predominant species (71.6%) fol- lowed by other NAC spp. (28.4%). Pregnancy and diabetes were the most frequently implicated risk factors (67.1% and 44.4%). High resistance was observed in NAC spp. as opposed to C. albicans to all antifungal agents tested. Conclusion: Empirical therapy with routinely used antifungals can be initiated for C. albicans. In the case of NAC spp., identification should be followed by susceptibility testing.
Objective The objective of this study is to find the organism profile and antimicrobial susceptibility patterns in children with cystic fibrosis (CF). Design Prospective cohort study. Setting Hospital-based study. Intervention Sputum cultures/throat swabs were collected from the study population. Relevant details like anthropometry, systemic examination findings and investigations were entered in a pre-designed format. Sputum culture was subjected to microbiological analysis at the hospital microbiology laboratory. Main outcome measure Prevalence of positive sputum/cough swab culture in CF patients, their organism profile and antibiotic sensitivity. Results A total of 63 patients were enrolled in the study. A total of 136 organisms were grown in our study population. Thirteen different organisms were isolated, which included five gram-positive bacteria, six gram-negative bacteria, eight Candida spp. and one filamentous. Antibiotic sensitivity profile of the Pseudomonas aeruginosa showed excellent sensitivity to all the aminoglycosides, piperacillin-tazobacteum and polymixin, similarly methicillin-sensitive Staphylococcus aureus, methicillin-resistant S. aureus and Enterococcus spp. were uniformly sensitive to vancomycin, linezolid and teicoplanin. Fungal isolates showed 100% sensitivity to all the antifungals tested including azoles and amphotericin B. Conclusion We observed 61% of culture positivity for different organisms in our study. Staphylococcus aureus and P. aeruginosa were the most frequently isolated organisms. Pseudomonas aeruginosa isolates were largely sensitive to aminoglycosides, carbapenems and polymixin. We found an unusually higher incidence of enterococcal infection in our study cohort with few vancomycin-resistant isolates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
