Molecular characterization of typing and subtyping of Staphylococcal cassette chromosome SCC types I to V in methicillin-resistant from clinical isolates from COVID-19 patients.

Background And Objectives: Methicillin resistance is acquired by the bacterium due to gene which codes for penicillin-binding protein (PBP2a) having low affinity for β-lactam antibiotics. gene is located on a mobile genetic element called staphylococcal cassette chromosome (SCC). SCC genomic island comprises two site-specific recombinase genes namely and [cassette chromosome recombinase] accountable for mobility.

Impact of COVID-19 Lockdown on Patients Undergoing Orthodontic Treatment: A Questionnaire Study.

Unlabelled: With COVID-19 declared as a worldwide pandemic, a nationwide lockdown was implemented overnight in India on March 24, 2020. With no prior warning or anticipation, patient appointments were temporarily ceased as institutions and clinics were indefinitely closed. To our knowledge, no study addresses the orthodontic patient perspective in such testing times, where they are entirely restricted to the confines of their homes.

Soluble expression of recombinant active cellulase in E.coli using B.subtilis (natto strain) cellulase gene.

Background: Cellulases are well known for their various industrial applications. They are naturally produced by different species of bacteria and fungi. Fermentation process of cellulase producers has limitation due to the high substrate cost required for cellulase induction and challenges to maintain the suitable condition for the respective cellulase production.
