Special Issue Information

Dear Colleagues,

This Special Issue is a continuation of our previous one, entitled “The Pathogenesis, Epidemiology and Diagnosis of Infectious Diseases in Livestock Animals”.

This Special Issue focuses on the pathogenesis, epidemiology, and diagnosis of infectious diseases in livestock animals. Infectious diseases in livestock can have a significant impact on animal health and productivity, as well as on human health and the economy. Therefore, it is crucial to understand the underlying mechanisms of these diseases and to develop effective strategies for their prevention, control, and diagnosis. For this Special Issue, we invite the scientific community to submit original scientific articles, reviews, opinion articles, and/or short communications from fields of research related to infectious diseases in livestock animals.

The articles published in this Special Issue will cover a range of topics related to infectious diseases in livestock. They will provide insights into the pathogenesis of various infectious agents, including viruses, bacteria, fungi, protozoa, and other parasitic pathogens, and how these agents interact with their hosts to cause disease. Papers related to the epidemiology of infectious diseases in livestock that address the factors that contribute to their dissemination and the methods used to control their transmission are also welcome to be submitted to this Special Issue.

In addition, this Special Issue aims to highlight the latest advances in the diagnosis of infectious diseases in livestock. We invite the submission of articles describing various diagnostic techniques, including traditional methods such as bacteriology, mycology, and virology, as well as newer diagnostic approaches such as molecular biology, new-generation sequencing, in situ hybridization, and immunohistochemistry. The use of these techniques in the detection, pathogenesis, and identification of infectious agents of livestock animals, as well as their advantages and limitations, is welcome to be elucidated in this Special Issue.

Overall, this Special Issue aims to provide a comprehensive overview of the current understanding of infectious diseases in livestock, as well as the tools and strategies available for their prevention, control, and diagnosis. We hope that this Special Issue will be a valuable resource for veterinarians, researchers, and policymakers involved in the fight against infectious diseases in livestock.

Mycoplasma suis infects pig red blood cells and is linked to anemia, weakened immunity, and production losses. Infected animals may remain subclinical carriers, contributing to pathogen dissemination. This study aimed to investigate the prevalence of M. suis in commercial pig farms in the state of Espírito Santo, Brazil. A total of 416 blood samples from 55 farms were analyzed using conventional PCR targeting the hemotropic Mycoplasmas (16S rRNA) and a species-specific PCR for M. suis (23S rRNA). Among the samples, 131 (31.49%) tested positive for hemoplasmas and 58 (13.94%) for M. suis with a significantly higher frequency in sows (p < 0.01). The Metropolitan microregion showed the highest prevalence (23.53%). The discrepancy between the prevalence for the genus and the species suggests the possible presence of other hemotropic Mycoplasma species and highlights the limitations of 16S rRNA-based assays. These findings emphasize the need for more specific molecular targets and continuous monitoring strategies to control infection in pig farming. Full article
