A pilot study of seroprevalence in occupationally exposed individuals in the Peace River region of Alberta and British Columbia.

A pilot seroprevalence study was performed among asymptomatic occupationally exposed individuals in June, 2016 in the Peace River region of Alberta and British Columbia. Five of 40 subjects - 3 of 24 small ruminant producers, 1 of 14 abattoir workers, and 1 of 2 veterinarians had evidence of exposure. More systematic surveillance and more active promotion of biosecure husbandry methods should be considered.

A comparison of diagnostic techniques for postpartum endometritis in dairy cattle.

Holstein cows (n=221) from eight commercial dairy herds were examined for endometritis between 28 and 41 days postpartum using 5 diagnostic techniques: (1) vaginoscopy; (2) ultrasonographic assessment of uterine fluid volume; (3) ultrasonographic assessment of endometrial thickness; (4) endometrial cytology collected by cytobrush; and (5) endometrial cytology collected by uterine lavage. Concordance correlation was used to evaluate the reliability of cytobrush and lavage cytology. Cytobrush cytology was found to have the greatest intraobserver repeatability (cytobrush, rho(c)=0.

Congenital hypotrichosis and partial anodontia in a crossbred beef calf.

Clinical examination, skin biopsies, skull radiographs, and DNA analysis of a 2-day-old Red Angus-Charolais-Simmental cross bull calf confirmed the diagnosis of congenital hypotrichosis and anodontia defect (HAD), also called anhidrotic ectodermal dysplasia, which is a rare anomaly caused by a deletion in the bovine EDA gene on the X chromosome.
