Paratuberculosis is an infectious disease which affects ruminants. In this work, a sheep flock in Garfagnana district (Tuscany, Italy) was examined by agar gel immune-diffusion (AGID) tests, culture, and PCR from feces, milk, tissue samples, and cheeses. At the first AGID test, 7/280 (2.5 %) animals were positive. From these animals, feces and milk samples were collected: 4/7 feces (57.14 %) and 2/7 milk samples (28.57 %) were positive to culture and 7/7 (100 %) feces samples and 1/7 milk samples (14.28 %) were positive to PCR; 2/4 (50 %) cheeses ripened for 14 days and 1/3 (33.33 %) cheese ripened for 20 days were positive to PCR, from which no viable microorganisms were isolated. Then, the AGID-positive animals were slaughtered and tissue samples were taken from one sheep with PCR-positive feces and milk: the liver, intestine, mesenteric lymph nodes, but not the spleen and mammary lymph nodes were positive to culture; all these samples were instead PCR-positive. After 1 year, a second AGID survey was performed on the remaining animals: 6/244 (2.45 %) subjects were positive to this test. Data obtained revealed the presence of paratuberculosis in a sheep population in Garfagnana.

Background: Maternal obesity may contribute to childhood obesity in a myriad of ways, including through alterations of the infant gut microbiome. For example, maternal obesity may contribute both directly by introducing a dysbiotic microbiome to the infant and indirectly through the altered composition of human milk that fuels the infant gut microbiome. In particular, indigestible human milk oligosaccharides (HMOs) are known to shape the composition of the infant gut microbiome.

Breastfeeding supplies nutrition, immunity, and hormonal cues to infants. Feeding expressed breast milk may result in de-phased milk production and feeding times, which distort the real-time circadian cues carried by breast milk. We hypothesized that providing expressed breast milk alters the microbiotas of both breast milk and the infant's gut.

Toxoplasmosis is a major veterinary and public health issue affecting humans and animals, where felids represent the definitive hosts of the causative agent . While the infections are mostly asymptomatic, the disease could be severe in immune-compromised patients and pregnant women. This study was conducted to evaluate the level of knowledge, practice, and attitude toward this disease among a sample of Algerian women.

This research investigated the influence of the microencapsulation of phenolic compounds (PCs) from organic coffee husk with whey protein concentrate (WPC) and maltodextrin on the abundance of intestinal bacterial populations and their metabolic activity during in vitro fecal fermentation. The microencapsulated PCs were gradually metabolized during fecal fermentation, resulting in significant transformations and an increase in PCs in the fermentation media. The metabolism of PCs by the fecal microbiota occurred concurrently with the consumption of sugars, production of organic acids, and reduction in pH in the media.
