Article Synopsis
  • Tuberculosis (TB) poses a significant health risk to both humans and non-human primates used in research, especially given the challenges posed by emerging mycobacterial species.
  • A natural outbreak of TB was found in imported cynomolgus macaques at AnaPath Research S.A.U. after initial negative tests, leading to extensive screening and diagnosis of the affected animals.
  • Despite most macaques showing no symptoms, necropsies confirmed TB in 10 out of 114 animals, tracing the infection back to Asia, while all sanitary measures taken successfully eradicated the disease.

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.

Soybean has a recognized narrow genetic base that often makes it difficult to visualize available genetic and phenotypic variability and identify superior genotypes during the selection process. However, the phenotypic expression of soybean plants is highly affected by photoperiod and the cultivation of a given variety is performed in the latitude range that presents ideal conditions for its development based on its relative maturity group (RMG) for the optimization of the phenotypic expression of its genotype. Based on the above, this study aimed to evaluate the efficiency of artificial neural networks (ANNs) as a tool for the correct discrimination and classification of tropical soybean genotypes according to their relative maturity group during the population selection process with the aim of optimizing the phenotypic performance of these selected genotypes.

Background: The impact of biologics on the risk of postoperative complications (PC) in inflammatory bowel disease (IBD) is still an ongoing debate. This lack of evidence is more relevant for ustekinumab and vedolizumab.

Aims: To evaluate the impact of biologics on the risk of PC.

The high-resolution WGS analyses of MTBC strains have provided useful insight for determining sources of infection for animal tuberculosis. In Spain, tuberculosis in livestock is caused by and , where wildlife reservoirs play an important role. We analyzed a set of 125 isolates obtained from livestock and wildlife from Catalonia to investigate strain diversity and identify possible sources and/or causes of infection.
