Effects of aroA deleted E. coli vaccine on intestinal microbiota and mucosal immunity Comp. Immunol. Microbiol. Infect. Dis. (IF 1.573) Pub Date : 2021-01-14 Breno C.B. Beirão; Max Ingberman; Dany Mesa; Gleidson B.C. Salles; Eduardo C. Muniz; Luiz Felipe Caron
E. coli infection of broilers can result in systemic diseases and productivity losses. Use of antimicrobials against this condition is common but other approaches, such as vaccination, are gaining ground. Anecdotal field reports indicate that intestinal health is improved unspecifically following E. coli live vaccination.

Recently, several ND outbreaks in pigeon caused by pigeon paramyxovirus serotype-1 (PPMV-1) have been reported from Iran, but unfortunately, phylogenetic studies have been mostly conducted on partial sequence of NDV fusion (F) gene. In addition, a complete genome data of Iranian PPMV-1 strains

Hepatic and splenic immune response during acute vs. chronic Brucella melitensis infection using in situ microscopy Comp. Immunol. Microbiol. Infect. Dis. (IF 1.573) Pub Date : 2020-10-02 Juliane Daggett; Alexandra Rogers; Jerome Harms; Gary A. Splitter; Marina Durward-Diioia
Brucella melitensis is an intracellular bacteria causing disease in humans as an incidental host. The infection initiates as acute flu-like symptoms and may transform into a chronic cyclic infection. This cyclic infection may be partly due to the bacteria’s ability to persist within antigen presenting cells and evade the CD8 + T cell response over long periods of time. This research aims to characterize

First report of Chlamydophila abortus infection in the dromedary camel (Camelus dromedarius) population in eastern Algeria Comp. Immunol. Microbiol. Infect. Dis. (IF 1.573) Pub Date : 2020-10-01 Mohammed Hocine Benaissa; Nora Mimoune; Curtis R. Youngs; Rachid Kaidi; Bernard Faye
Chlamydiosis is caused by an obligate intracellular gram-negative bacterium of the genus Chlamydophila which is a zoonotic pathogen. The objectives of the study were to identify the seroprevalence of antibodies against Chlamydophila abortus in dromedary camel herds from four districts in eastern Algeria, as well as to estimate the association between seroprevalence and certain factors present at the

Leptospirosis in horses is often associated with reproductive disorders. In the southern states of Brazil, horses are used for various jobs and cultural practices; nevertheless, serological surveillance for Leptospira is rare. Therefore, the objective of this study was to determine the seroprevalence of Leptospira spp. in horses in southern Brazil, as well as to identify the risk factors for infection

The first experimental infections with Leptospira in ruminants were conducted in the 1950s, primarily assessed the pathogenesis caused by serovar Pomona in cows. Throughout the decades, experimental infections have also demonstrated the clinical aspects of the infection by other strains, mainly Hardjo. Despite the important outcomes observed in experimental infections in ruminants, there is still a
