A 2-year old gelding was referred for evaluation of severe right forelimb lameness. The horse was grade 4/5 lame on the right forelimb. Clinical, laboratory, and radiographic findings were consistent with septic arthritis and osteomyelitis. Due to poor prognosis the owner elected euthanasia. Histopa...

The prevalence of Giardia duodenalis, Cryptosporidium spp. and other intestinal parasites was determined in dogs <1 year old from Prince Edward Island, Canada. Fecal samples were collected from the local animal shelter (n=62), private veterinary clinics (n=78) and a pet store (n=69). Intestinal para...

Intratesticular injection of EsterilSol (zinc gluconate neutralized with arginine) is a chemical sterilant for male dogs sometimes used in population control campaigns. Adverse reactions have been reported in 1% to 4% of treated dogs, but detailed histomorphologic descriptions are lacking. During a ...

Evidence in the literature exists to support the theory that mastitis and intramammary infection (IMI) tend to cluster within herds, within cows, and within quarters, facts which may have overarching ramifications on mastitis management in modern dairy herds. Most previous studies, however, have bee...

Many subtypes of low-pathogenicity avian influenza (LPAI) virus circulate in wild bird reservoirs, but their prevalence may vary among species. We aimed to compare by real-time reverse-transcriptase polymerase chain reaction, virus isolation, histology, and immunohistochemistry the distribution and ...

Autologous mesenchymal stem cells (MSCs) have been used as a potential cell-based therapy in various animal and human diseases. Their differentiation capacity makes them useful as a novel strategy in the treatment of tissue injury in which the healing process is compromised or delayed. In horses, bo...

The control of the ectoparasite, sea lice (L. salmonis), on farmed Atlantic salmon in Eastern Canada was complicated by the development of resistance to emamectin benzoate, the primary in-feed medication used since 2000. Field efficacy and bioassay assessments were initiated to address the emergency...

Background Recent focus on earlier detection of pathogen introduction in human and animal populations has led to the development of surveillance systems based on automated monitoring of health data. Real- or near real-time monitoring of pre-diagnostic data requires automated classification of recor...

Cysts of the protozoan parasite Giardia have been detected in many bivalve shellfish species worldwide. The detection of zoonotic Giardia duodenalis assemblages A and B is of public health concern, yet there is limited data available demonstrating the bioaccumulation and elimination of Giardia cysts...

Background: The proportion of geriatric horses within the equine population has increased in the past decade, but there is limited information on the immune function of these animals. Hypothesis: Aged horses will have a lesser increase in serum antibody response to vaccination. Animals: Thirty-four ...

The general objective of this study was to evaluate a crude Ostertagia ostertagi antigen enzyme-linked immunosorbent assay (ELISA) for monitoring gastrointestinal parasites in lactating dairy cattle. A longitudinal study of gastrointestinal parasites in lactating dairy cows was carried out in 38 her...

Four hundred eighty mature marine mussels (Mytilus edulis) were collected in late April from a mussel lease in an estuary in Prince Edward Island, Canada. Squash preparations made of reproductive gland (mantle) tissue of each mussel were stained with Wright-Giemsa stain and were examined by one inve...

The Canadian lobster industry holds lobsters Homarus americanus in captivity for various periods to supply markets with live product year-round. Mortality during holding results in considerable losses, estimated at 10 to 15 % yr(-1) by the industry. This study examined the prevalence of Anophryoides...

A lymphocyte stimulation test using antigens of Corynebacterium equi was used to compare the response of peripheral blood lymphocytes from foals with C equi pneumonia with those of clinically normal foals and adult horses. The test clearly distinguished infected foals from normal foals when tested i...

Since all retroviruses possess reverse transcriptase (RT) enzyme, reverse transcriptase activity has been the main supportive evidence of retroviral etiology of haemic neoplasia (HN) in soft shell clams, Mya arenaria. The objective of the present study was to search for a putative retrovirus in vari...

An indirect Ostertagia ostertagi ELISA was used in late lactation milk samples from cows in confined and semi-confined dairy herds to determine if it could predict milk production response after endectocide treatment at calving. Holstein cows from 9 dairy farms from Prince Edward Island (PEI), 5 fro...

A lesion in the cervical region of a 14-month-old Belgian gelding with severe ataxia was suspected. Necropsy revealed symmetric focal cartilage defects compatible with osteochondrosis of the occipital condyles and atlanto-occipital dysplasia. To our knowledge this is the first equine report of symme...
