COMMENT: Experiments in mice suggest that Bacteroides fragilis change its surface to faciliate the binding of IgA. It facilitates adherence to gut mucosa in vivo. The authors propose that IgA mediated responses are involved in the stablishment... + info
Early Salmonella Typhimurium infection in pigs disrupts Microbiome composition and functionality principally at the ileum mucosa.
Argüello H, Estellé J, Zaldívar-López S, Jiménez-Marín Á, Carvajal A, López-Bascón MA, Crispie F, O'Sullivan O, Cotter PD, Priego-Capote F, Morera L, Garrido JJ. Sci Rep. May 2018. doi: 10.1038/s41598-018-26083-3.
COMMENT: Salmonella is a major foodborne pathogen with a significant number of cases and outbreaks every year. Poultry meat, eggs and pork are the main sources of human salmonellosis. The host microbiota may play a role in resistance to, and... + info
León-Palmero E, Joglar V, Álvarez PA, Martín-Platero A, Llamas I, Reche I. PLoS One. 2018. doi: 10.1371/journal.pone.0196178.
COMMENT: Microbial pathogens, including bacteria and fungi, are responsible for multiple diseases. These infections affect not only humans but also crops, livestock, and aquaculture generating the need of new antimicrobial agents, in part, due... + info
