Abstract Hepatitis E virus (HEV) causes 20 million infections worldwide yearly, of which only about 3.3 million are symptomatic. In developed Asian countries, HEV strains detected in human sera and in food sources were genetically similar, suggesting that indigenous HEV infections may be largely food‐borne. To assess the burden of hepatitis E in Singapore, we performed a seroepidemiologic study...

Vibrio cholerae mutants lacking lytic transglycosylases MltC and RlpA are defective for daughter cell separation. Our results suggest that lytic transglycosylases at the division septum serve as a back‐up mechanism to cleave peptidoglycan strands that cannot be cleared by highly‐regulated amidase activity and to clear peptidoglycan debris that may block the completion of outer‐membrane...
