Shigella flexneri Adherence Factor Expression in In Vivo-Like Conditions

Despite significant gains in understanding of Shigella infection, it remains unknown how the bacteria initiate contact with the colonic epithelium. This research identified conditions that mimic some features of gastrointestinal transit and that enable Shigella to express adherence structural genes.

A review of asymptomatic and sub-clinical Middle East Respiratory Syndrome Coronavirus Infections

Researchers conducted a review of molecular and serological investigations through PubMed and EMBASE from September 2012 to 15 November 2018 to measure sub-clinical or asymptomatic Middle East Respiratory syndrome coronavirus (MERS-CoV) infection within and outside of health care settings.

Genetic, Molecular, and Pathogenic Characterization of the H9N2 Avian Influenza Viruses Currently Circulating in South China

Eight viruses isolated from farmed poultry in South China during 2017–2018 were selected as representative strains for further systematic study. Findings suggested that the H9N2 AIVs circulating in poultry recently acquired an enhanced ability to transmit from avian to mammalians, including humans.

Malaria Transmission in Madagascar: Study reveals new findings

A new study describes the application of effective mosquito surveillance using low-cost traps and a tool that tests each mosquito’s species, feeding material, and the presence of malaria parasites. The study also provides new information that may improve understanding of how malaria is transmitted and consequently could be controlled, including that the female Anopheles mosquitoes (the ones that transmit malaria) diets are more varied than previously assumed.
