BACKGROUND: Carbapenemase-producing Pseudomonas aeruginosa is a serious threat in hospital infection due to its multidrug resistance. AIM: The aim of the study was to determine the frequency of carbapenem resistance in clinical isolates of Pseudomonas aeruginosa and detect the presence of carbapenemase enzymes in carbapenem-resistant P. aeruginosa (CRPA) isolates by phenotypic and genotypic methods. MATERIAL AND METHODS: Double-disk synergy test [DDST] and combined disk synergy test [CDST]) was performed in CRPA isolates and the prevalence ofblaKPC,blaNDM-1,blaIMP,blaVIM,blaSIM,blaSPM,blaGIM, andblaOXA-48 was determined. RESULTS: Of 559 isolates included in the study, a total of 102 isolates were resistant to carbapenem that accounted for overall 18.24% (102/559) prevalence. Of these 102 isolates, 89 (87.25%) isolates were positive by DDST and 95 (93.17%) isolates were positive by CDST. Of 102 CRPA isolates,blaVIM was detected in 30 isolates (30/102, 29.1%), followed byblaNDM-1 in 29 (29/102, 28.4%) isolates andblaSIM andblaGIM in 6 isolates each (6/102, 5.8%). A combination of two carbapenemase genes was detected in 12 isolates, with six (6/102, 5.88%) CRPA isolates harboring with bothblaVIM andblaNDM-1 genes. Four isolates were found to harbor a combination of three carbapenem-resistant genes. CONCLUSION: A high rate of carbapenemase production was observed in P. aeruginosa. Coproducers of multiple carbapenemases are also a cause of concern. An in-depth understanding of molecular mechanisms of resistance will be helpful in optimizing patient management and hospital infection control.

We are in the middle of a pandemic of COVID-19. Objective of the study is to study the epidemiology of SARS-CoV-2 in India and its comparison to SARS-CoV and Spanish flu.Data used are primarily obtained from Worldometer, WHO and CDC. We have plotted bar and line charts based on MS-Excel.Comparative evaluation of COVID-19 data of India and World has been done which shows that with COVID-19 containment and mitigation strategy the total number of recovered patients is increasing day by day and surpassing total number of active infection in India as well as world.With continued non-pharmacological measures like social distancing, hand hygiene, judicious use of mask and effective lockdown, would definitely prove helpful in battle against COVID-19.
