Echocardiographic Documentation of Dilated Cardiomyopathy Development in Dogs Naturally Infected with .

We aimed to characterize the echocardiographic alterations in dogs from an endemic region that were naturally infected with . Dogs (n = 130) seropositive for antibodies against and/or with acute parasitemia were enrolled in the study. Indicators of changes in the structure and systolic and diastolic functions of the left ventricle (LV) and blood flow patterns were evaluated by echocardiography.

Effect of Foliage on Intake, Kinetics of Fermentation and Passage and Microbial N Supply in Sheep Fed Hay.

An experiment was carried out to assess the effect of the incorporation of sun-dried foliage of into rations based on hay of on intake, rumen fermentation, kinetics of passage, microbial nitrogen supply to the small intestine, apparent digestibility in Pelibuey hair sheep. Four rations were randomly allotted to four rumen-cannulated lambs (BW = 37.4 ± 4.

Prevalence and Progression of Gingivitis in Domestic Cats in Subtropical Mexico.

With the objective to characterize the gingival index (GI) and its progression, 218 domestic cats in a subtropical region of Mexico were studied. All teeth of each cat were examined with a periodontal probe to determine the GI; in addition, the absence of teeth was recorded. Six months later, the teeth of the 38 cats were again examined to assess any progression of the GI and loss of teeth.

Evidence of differentiation and population structure in Charolais cattle of Mexico.

Charolais is one of the most important beef cattle breeds in the world. In Mexico, it was introduced almost a century ago, and it has been suggested that particular breeding management and genetic material origin have caused a process of divergence among the current population. By a high-density SNP array genome-wide analysis, this study aimed to assess the proposed differentiation and population structure of local populations by genetic distances and structure approaches, and a European Charolais sample was included as a reference population.

Congenital Transmission of in Naturally Infected Dogs.

Congenital transmission (CT) of in dogs has not been clearly demonstrated, even though dogs are important reservoirs of this agent. Seventeen late pregnant dogs seropositive for were selected, and a total of 84 fetuses were obtained. Blood and heart tissues from the fetuses and dams, and placental tissue from dam were collected.
