Conserved core microbiota in managed and free-ranging elephants.

The gut microbiota plays a crucial role in animal health and homeostasis, particularly in endangered species conservation. This study investigated the fecal microbiota composition of European captive-bred African savanna elephants () housed in French zoos, and compared it with wild African savanna elephants. Fecal samples were collected and processed for DNA extraction and amplicon sequencing of the 16S rRNA gene.

Comparison of qPCR and blood smear microscopy for the diagnosis of in a French veterinary practice.

() is an haemotropic Mycoplasma that adheres and invades erythrocytes and is responsible for infectious anaemia of pigs. Infections with have been reported worldwide. Clinical signs after infection can be significant particularly for the breeding herd in the period around farrowing but consequences are highly variable with some infected pigs never exhibiting clinical disease.

Monitoring PRRSV-1 in suckling piglets in an endemic herd using reverse transcriptase quantitative real time polymerase chain reaction: comparison of the rate of detection in serum and oral fluid samples and evaluation of pooling.

Background: Defining shedding and exposure status for PRRSV is essential in herd stabilisation protocols and weaning-age pigs is a key subpopulation. Oral fluid (OF) sampling is a welfare-friendly and cost saving promising alternative to blood sampling. The first objective of our study was to compare the rate of detection of PRRSV-1 in individual serum sample, individual OF sample, litter-based OF sample, collected the day before weaning.

Utility of an internal control for evaluation of a Mycoplasma meleagridis PCR test.

Mycoplasma meleagridis, a turkey pathogen, can be detected by PCR directly from tracheal or genital swabs. However, up to 40% samples may contain inhibitory substances. A DNA fragment, that can be amplified with M.
