Evaluating the use of salivary anti-CarLA IgA testing to reduce gastrointestinal parasitism in Canadian pastured sheep.

Gastrointestinal nematode (GIN) parasitism is common in Canadian sheep flocks, and managing GIN through the selection of sheep with superior immunity is of growing interest. The CARLA ® Saliva Test measures salivary IgA against the carbohydrate larval antigen (CarLA) found on third-stage larvae of all GIN species. Salivary anti-CarLA IgA exceeding 1.

Leiomyosarcoma with widespread metastases in a capybara.

A 10.5-y-old intact female capybara () with a history of chronic weight loss was euthanized following discovery by palpation of a large intra-abdominal mass. Postmortem examination revealed a large, firm, tan mass expanding the uterine body and extensively adhered to the jejunum and abdominal wall.

Correlation of subclinical gastrointestinal nematode parasitism with growth and reproductive performance in ewe lambs in Ontario.

Infection with gastrointestinal nematode parasites (GINs) is an important cause of productivity loss on sheep farms in Ontario and worldwide. However, efforts to quantify the effect of GIN infection on growth have demonstrated mixed results. Furthermore, there has been limited investigation of their effect on reproductive performance.

Correlation of salivary antibody to carbohydrate larval antigen (CarLA) with health and gastrointestinal nematode parasitism in sheep under Ontario grazing conditions.

Leveraging mucosal immunity is a promising method for controlling gastrointestinal nematode (GIN) parasitism in sheep. Salivary antibody to carbohydrate larval antigen (sCarLA), a heritable measure of immunity to third-stage GIN larvae (L), has been successfully applied to genetic improvement programs in New Zealand. However, sCarLA levels wane in the absence of ongoing GIN exposure.

Retropharyngeal abscess with carotid involvement presenting as fever of undetermined origin in a dog.

A young dog was presented with lethargy and pyrexia of 2 days duration, not responding to empirical treatment. Thorough diagnostic investigation failed to determine the cause. A retropharyngeal abscess became apparent when it eroded into the carotid artery 2 days later.
