Different repartition of the cryptic species of black aspergilli according to the anatomical sites in human infections, in a French University hospital.

Med Mycol 2021 May 22. Epub 2021 May 22.

Laboratoire de Parasitologie-Mycologie, Hôpital Lariboisière Saint-Louis Fernand Widal, Assistance Publique-Hôpitaux de Paris (AP-HP), France.

Black aspergilli of the section Nigri are rarely differentiated at the species level when originating from human specimens. We wondered whether some cryptic species could be more frequently observed in some clinical entities. We analyzed the 198 black isolates consecutively collected from the external ear canal (EEC; n = 66), respiratory specimens (n = 99), and environment (n = 33). Read More

Microbial community structure and composition is associated with host species and sex in Sigmodon cotton rats.

Anim Microbiome 2021 Apr 16;3(1):29. Epub 2021 Apr 16.

Pathology Microbiology and Immunology, Vanderbilt University Medical Center, Nashville, TN, USA.

Background: The cotton rat (genus Sigmodon) is an essential small animal model for the study of human infectious disease and viral therapeutic development. However, the impact of the host microbiome on infection outcomes has not been explored in this model, partly due to the lack of a comprehensive characterization of microbial communities across different cotton rat species. Understanding the dynamics of their microbiome could significantly help to better understand its role when modeling viral infections in this animal model. Read More

Community Use of Face Masks against the Spread of COVID-19.

Int J Environ Res Public Health 2021 03 19;18(6). Epub 2021 Mar 19.

Public Health Department, Local Health Unit N.2 "Marca Trevigiana", 31100 Treviso, Italy.

The role of face masks to prevent and control COVID-19 is critical, especially since asymptomatic or pre-symptomatic infected individuals can shed high loads of SARS-CoV-2 in the surrounding environment. In addition to being a two-way barrier to protect against virions droplets both in terms of "source control" (for the benefits of the community) and "physical protection" (for wearer), face masks also allow maintaining physiological temperatures and humidity of the nasal cavity and mouth, independently from the external environmental conditions. Beyond compromising the viral transmission speed, exposure to cold environments could have a detrimental effect on the host's susceptibility to SARS-CoV-2. Read More
