Introduction: Bovine tuberculosis (TB) in water buffalo (Bubalus bubalis) is primarily diagnosed using intra vitam tests, as the intradermal tuberculin test (IDT) and the interferon-gamma release assay (IGRA), both of which detect cell-mediated immunity (CMI). However, a subset of infected animals fails to mount a detectable CMI response, posing a significant risk of undetected transmission. Serological tests assessing the humoral immune response could provide a valuable complementary tool for identifying infected animals that escape detection through traditional CMI-based assays. Methods: Th… Leer más

Persistent multispecies dissemination of armA-carrying IncR plasmids among clinical and environmental bacterial populations in a Spanish veterinary hospital

Artículo de investigación publicado en Journal of Clinical Microbiology

Aminoglycoside resistance mediated by 16S rRNA methyltransferases poses a growing threat in both human and veterinary medicine. Here, we conducted a retrospective genomic study of Enterobacterales isolates (n = 789) collected from clinical samples at a veterinary teaching hospital in Spain between 2011 and 2020. We identified four high-level aminoglycoside-resistant ST171 Enterobacter hormaechei subsp. xiangfangensis isolates carrying the armA gene, all from horses. Using Illumina and Nanopore sequencing, we determined that armA was located on a 70 kb IncR plasmid, also carrying other resistan… Leer más

A time-space Bayesian regression model of rabies cases in the animal population of Kazakhstan (2013-2023)

Frontiers in veterinary science publica este artículo de investigación

Despite its endemic status and socioeconomic impacts, the spatial-temporal variation in rabies risk and its underlying determinants in Kazakhstan animal populations remain poorly understood. This study aimed to characterise the time-space dynamics of rabies in animal populations across Kazakhstan regions from 2013 to 2023 and identify the key drivers of transmission. Using a Bayesian hierarchical regression model with spatial and temporal random effects, we analysed national surveillance data on rabies cases in livestock, companion animals, and wildlife, alongside sociodemographic and animal p… Leer más

Protective effect of heat-inactivated Mycobacterium bovis applied intramuscularly is associated with enhanced lung immune response in caprine tuberculosis

Investigación publicada en Veterinary Research

Caprine tuberculosis (TB) causes a zoonotic disease with significant economic and health implications. However, excluding some regions, goat herds are not subjected to official TB eradication programs. Implementing vaccination protocols for this species could provide a complementary and effective control strategy against TB. We assessed the protective efficacy and immune response associated with a heat-inactivated Mycobacterium bovis (M. bovis)-based immunostimulant (HIMB) applied intramuscularly against caprine pulmonary TB on 20 kid goats (10 immunized, 10 controls) naturally exposed to M. c… Leer más

Diving Into the Depths: Unveiling the Main Etiologies of Piscine Lactococcosis With a Novel Multiplex qPCR Assay

Investigación publicada en Journal of Fish Diseases

Piscine lactococcosis poses a significant threat to a wide range of cultured and wild fish populations worldwide, typically presenting as acute haemorrhagic septicemia with high morbidity and mortality. Although Lactococcus garvieae was historically considered the sole causative agent of piscine lactococcosis, recent studies have identified L. petauri and L. formosensis as additional, highly pathogenic species. In this study, we developed a novel TaqMan-based multiplex qPCR assay for the simultaneous detection and differentiation of L. garvieae, L. petauri and L. formosensis, following a pange… Leer más
