ABSTRACT
AIM: This study was carried out to determine the fungal profile and antifungal susceptibility pattern in the brushing samples of candidiasis in patients with carcinoma of esophagus. MATERIALS AND METHODS: The study was carried out in the Departments of Microbiology and Surgical Oncology of a regional cancer center from January 2017 to December 2017. Samples were collected under all aseptic precaution and Clinical Laboratory Standards Institute guidelines 2017 was followed for antifungal susceptibility testing. RESULTS: A total of 132 endoscopy brushing samples were collected from histological proven esophageal cancer patients and processed for fungal culture. Of which, 75 (56.81%) samples showed culture positivity and were recruited. Candida albicans in 40 (53.33%), Candida krusei in 25 (33.33%), Candida tropicalis in 7 (9.33%), and Candida glabrata in 3 (4%) patients were seen. Among the 40 C. albicans isolates, all were sensitive to caspofungin - 40 (100%), 34 (85%) showed sensitivity to fluconazole, and 32 (80%) showed sensitivity to flucytosine. C. krusei and C. tropicalis showed 100% sensitivity to caspofungin, and C. glabrata isolates showed 100% resistance to caspofungin and 80% resistance to Amphotericin B. CONCLUSION: The present study revealed the emergence of multidrug-resistant, nonalbicans Candida isolates in cancer esophagus patients with candidiasis in northeast India.

Background This study was performed to determine the bacteriological profile and antibiotic sensitivity pattern of culture samples of patients with cancer at our institute. The study was undertaken to formulate an antibiotic policy for the treatment of infection in these patients. Materials and Methods The study was performed in the Department of Microbiology of a regional cancer center during the period from January 2017 to December 2017. Samples were collected under all aseptic precaution, and they were processed as per the Clinical and Laboratory Standard Institute Guideline 2017. Results A total of 464 clinical samples (urine, blood, sputum, pus, etc.) were collected and processed for culture, of which 198 (42.67%) samples showed culture positive that were identified as per standard recommended procedures and antibiotic susceptibility testing was performed on isolates as per the Clinical Laboratory Standard Institute guidelines 2017. Escherichia coli (48), Staphylococcus aureus, (45) Klebsiella pneumoniae (52), Coagulase-negative Staphylococcus (17), and Pseudomonas aeruginosa (15) were most commonly encountered. Of the 132 Gram-negative isolates, 101 (76.5%) were extended-spectrum ß-lactamase producers. Among the 45 staphylococcal isolates, 18 (40%) were methicillin-resistant S . aureus. Conclusion The present study reveals microbiological profile in patients attending our cancer institute.
ABSTRACT
AIM: This study was carried out to determine the bacteriological profile of infected diabetic foot ulcers (DFUs) and the antibiotic resistance pattern from the isolates. An attempt was made to suggest an empiric antibiotic regimen to treat such patients. MATERIALS AND METHODS: Tissue samples were collected from 150 patients between February 2015 and January 2016 with DFUs under aseptic precautions and they were processed as per the Clinical and Laboratory Standards Institute guidelines. RESULTS: A total of 185 bacterial isolates were obtained from 150 persons with diabetic and with foot ulcers. The age group of these persons ranged from 35 to 80 years and the maximum number of persons with DFUs was in the age group of 60-65 years. Among the isolates, Gram-negative bacilli were isolated in 112/185 (61%) and Gram-positive cocci in 73/185 (39%) cases. The most common isolate was Staphylococcus spp. 46 (25%), followed by Escherichia coli (20%) and Enterococcus spp. (15%). The antibiotic sensitivity profile of the bacteria was also studied. Among the isolates, 59/112 (53%) of the Gram-negative bacilli were extended spectrum beta-lactamase producers, 19/46 (41%) were methicillin-resistant Staphylococcus aureus, and 5/27 (19%) were vancomycin-resistant Enterococcus. CONCLUSIONS: This study showed a preponderance of multidrug-resistant strains among the isolates from the DFUs. Knowledge on the antibiotic sensitivity pattern of the isolates will be helpful in determining the drugs for the empirical treatment of diabetic ulcers. Thus, indiscriminate use of antibiotics and chances of subsequent development of antibiotic resistance can also be reduced.
