Milbemycin oxime was used to treat dogs with natural infections of the fox lungworm, Crenosoma vulpis and the French heartworm, Angiostrongylus vasorum. Crenosomosis was identified in 42 of 202 dogs with clinical signs of coughing, dyspnoea or exercise intolerance by a Baermann analysis of faecal sa...

The long-term (i.e., 4-5 months) effects of large doses (3 X 50 mg/kg) of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on striatal dopamine-containing afferents were studied in the NMRI strain of mice. Recently improved in vivo electrochemical methods were first used to examine the magnitude,...

A young, female llama (Lama glama) was euthanized following the onset of hindleg paresis and paralysis. Live trematodes, identified as Fascioloides magna, were identified from the liver of this animal. This represents the first report of F. magna in a llama.

The guinea pig was used to study the pathology of Fascioloides magna, an important pathogen for sheep. Although flukes migrated freely through various tissues in infected guinea pigs, the most serious lesions occurred in the liver and lungs. The sequential development of lesions indicated that fluke...

Crenosoma vulpis is a nematode lungworm that is highly prevalent in the red fox population of Atlantic Canada. Dogs are susceptible to infection with clinical signs consisting primarily of a chronic cough. A recent report of C. vulpis infection in 3 dogs on Prince Edward Island prompted an investiga...

Larvae of Trichinella sp. were found in two of 208 red foxes (Vulpes vulpes) and one of 125 coyotes (Canis latrans) obtained from trappers from Prince Edward Island (Canada) in 1995 and 1996. A polymerase chain reaction based DNA biotyping method revealed the larvae to be isolates of Trichinella spi...
