Article Synopsis
- SARS-CoV-2 has been infecting various animal species, with farmed minks showing the highest outbreak cases; a study in Spain analyzed genomic sequences from 18 of these outbreaks.
- Researchers identified four distinct lineages of the virus (B.1, B.1.177, B.1.1.7, AY.98.1) and noted a range of mutations that accumulate rather than follow specific lineage patterns.
- Key mutations in the virus could improve its ability to infect hosts, raising concerns about transmission to humans and indicating the importance of monitoring genetic changes in the virus within mink populations.
Background: The European bison (Bison bonasus), a symbol of Polish nature, is a protected species that requires active health monitoring. However, conservation efforts are made difficult by the zoonotic diseases such as brucellosis and tuberculosis.
Objective: The aim of this study was to screen the Polish European bison population for exposure to the Mycobacterium tuberculosis complex (MTC) and Brucella spp.
Article Synopsis
- Tuberculosis (TB), caused by the Mycobacterium tuberculosis complex, affects multiple animal species and understanding its epidemiology in Mediterranean ecosystems is crucial for control efforts.
- Recent outbreaks involving sheep, traditionally seen as spillover hosts, highlight the need to study their role in TB transmission.
- A study in Andalusia tested 2,266 sheep for TB antibodies, finding a low seroprevalence (0.7%) but identifying semi-extensive management as a risk factor, suggesting sheep have a limited role in the local TB epidemiology.
P22 protein complex in the serodiagnosis of animal tuberculosis: Antigenic stability and cross-reactivity with Corynebacterium pseudotuberculosis infection.
Comp Immunol Microbiol Infect Dis
November 2022
The P22 ELISA was recently developed for the serodiagnosis of animal tuberculosis. Herein, the stability of the P22 antigen in different presentations and storage conditions, and the cross-reactivity with Corynebacterium pseudotuberculosis infection in small ruminants were evaluated. For the stability assay, serum samples from cows, sheep, goats, alpacas, badgers, and wild boar were used in the P22 ELISA.

Caprine TB eradication programmes are based mainly on intradermal tuberculin tests and slaughterhouse surveillance. However, the use of serological test has been extended as a potential diagnostic tool in goats through the use of serum, plasma, or even milk samples.
