Publication Ampicillinase C Beta-lactamase Producers among Isolates of Enterobacteriaceae in a Tertiary Care Centre: A Descriptive Cross-sectional Study(Nepal Medical Association, 2022) Khadka, Shusila; Barakoti, Achut; Adhikari, Ram Prasad; Khanal, Laxmi Kant; Sapkota, JyotshnaAbstract Introduction: Ampicillinase C beta-lactamase-producing organisms are often resistant to multiple antimicrobial agents, and therapeutic options against these pathogens are limited. Limited information is available regarding Ampicillinase C beta-lactamase producers. The aim of this study was to find out the prevalence of Ampicillinase C beta-lactamase producers among isolates of Enterobacteriaceae in a tertiary care centre. Methods: A descriptive cross-sectional study was carried out in the Clinical Microbiology Laboratory of a tertiary care centre from May 2021 to October 2021. Ethical approval was received from the Institutional Review Committee (Reference number: 044-077/078). Isolates of Enterobacteriaceae from various clinical samples were collected by convenience sampling. Ampicillinase C screening for beta-lactamase producers among the Enterobacteriaceae isolates was done using cefoxitin (30 μg) disc. Detection of Ampicillinase C beta-lactamase producers among the screen-positive isolates was done by cefoxitin-cloxacillin double-disc synergy test. An increase in the zone size of ≥4 mm was considered as Ampicillinase C beta-lactamase producers. Point estimate and 95% Confidence Interval were calculated. Results: Among the total 481 isolates of Enterobacteriaceae, 49 (10.19%) (7.50-12.90, 95 % Confidence Interval) were detected as Ampicillinase C beta-lactamase producers among isolates of Enterobacteriaceae. Conclusions: The prevalence of Ampicillinase C beta-lactamase producers was lower than in other studies done in similar settings. Meropenem could be a drug of choice for the treatment of infections due to Ampicillinase C beta-lactamase-producing gram-negative bacteria.Publication Positive Bacterial Culture among Lower Respiratory Tract Specimens of Patients in a Tertiary Care Centre: A Descriptive Cross-sectional Study(Nepal Medical Association, 2022) Khadka, Shusila; Barakoti, Achut; Adhikari, Ram Prasad; Khanal, Laxmi Kant; Sapkota, JyotshnaAbstract: Introduction: Lower respiratory tract infection accounts for a great burden of disease worldwide. The problem has further increased due to increasing antimicrobial resistance. This study was done to find out prevalence of positive bacterial culture among lower respiratory tract specimens of patients in a tertiary care centre. Methods: A descriptive cross-sectional study was done in the Laboratory of Clinical Microbiology in a tertiary care centre from May, 2021 to October, 2021. Ethical approval was received from the Institutional Review Committee (Reference number: 045-077/078). A total of 635 specimens were collected by convenience sampling. The specimens were cultured as per standard microbiological techniques. Antibiotic susceptibility was performed following Clinical and Laboratory Standards Institute (2020) guidelines. Microsoft Excel was used for data entry and analysis. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion. Results: Among the 635 lower respiratory specimens, 112 (17.63%) (111.97 to 112.03 at 95% Confidence Interval) showed positive bacterial culture. Klebsiella pneumoniae 44 (37.93%) was the commonest isolate followed by Acinetobacter calcoaceticus baumannii complex 34 (29.31%). Conclusions: The prevalence of positive bacterial culture among lower respiratory specimens was lower when compared to other studies done in similar settings.Publication Positive Bacterial Culture among Lower Respiratory Tract Specimens of Patients in a Tertiary Care Centre: A Descriptive Cross-sectional Study(Nepal Medical Association, 2022) Khadka, Shusila; Barakoti, Achut; Adhikari, Ram Prasad; Khanal, Laxmi Kant; Sapkota, JyotshnaAbstract Introduction: Lower respiratory tract infection accounts for a great burden of disease worldwide.

Healthcare workers mobile phones may act as vehicle for nosocomial infections. Mobile phones are rarely cleaned and healthcare workers frequently use them thorough out their time in hospitals. The objective of this study is to determine the rate of contamination of mobile phones, prevalent microorganisms and their antibiotic sensitivity pattern. Methods: The descriptive cross-sectional study was carried out in Clinical Microbiology laboratory from July 2019 to September 2019 after ethical approval. Samples were collected aseptically by rolling sterile swabs over the exposed surfaces of the mobile phones and inoculated on the agar plates and incubated aerobically. After incubation, plates were examined for growth. Bacteria were identified by standard microbiological procedure and antibiotic sensitivity test of isolated pathogens was done using Muller Hinton Agar by Kirby-Bauer method. Statistical analysis was done by Excel 2018. Results: Of the 198 mobile phones sample cultures, 112 (56.6%) samples showed 7 different types of bacteria. Mixed growth was observed in 3 mobile phones and total of 115 bacterial isolates were identified. Staphylococcusspecies (74.7%) were predominant organism followed by Acinetobacter spp, Klebsiella pneumoniae, E. coli, Citrobacter and Pseudomonas aeruginosa. Total 37.5% of Staphylococcus aureus were methicillin-resistant Staphylococcus aureus (MRSA). Conclusion: Mobile phones may have potential pathogenic microorganisms on their surface and can act as vector in spread of infectious agents in hospital settings. It is recommended to disinfect mobile phones regularly and to implement hand washing practices and regulations around the use of mobile phones in hospital settings.
