an eastern equine encephalomyelitis (eee) outbreak in quebec in the fall of 2008.eastern equine encephalomyelitis (eee) was diagnosed in 19 horses and a flock of emus in the province of quebec in fall 2008. the eee virus caused unusual gross lesions in the central nervous system of one horse. this disease is not usually present in quebec and the relation between the outbreak and favorable environmental conditions that summer are discussed.201021119870
serological studies on leptospirosis in domestic animals in quebec.during a period of 30 months, from january 1977 to june 1979, leptospira agglutinins were detected in 355 (6%) of 5841 bovine sera, 52 (10.1%) of 511 porcine sera, one (5%) of 20 equine sera and one (12.5%) of eight canine sera. bovine, porcine and equine sera reacted predominantly with l. pomona. reactors to l. hardjo/sejroe, l. icterohaemorrhagiae and l. grippotyphosa were also detected in cattle. one porcine serum reacted with l. grippotyphosa and one canine serum with l. icterohaemorrhagiae. ...19807407694

a short incubation serum neutralization test for bovine viral diarrhea virus.a three day serum neutralization (sn) test for the detection of antibodies to bovine viral diarrhea virus (bvdv), which is an improvement on the existing five day test, is described. the improved test results in a more rapid viral cytopathic effect and utilizes madin darby kidney (mdbk) cells, and horse serum as a medium supplement. a comparison of tests utilizing the nadl and the singer strains of bvdv and the use of either secondary bovine kidney cells with calf serum (bkcs) or continuous mdbk ...19921317246
field efficacy of ivermectin plus praziquantel oral paste against naturally acquired gastrointestinal nematodes and cestodes of horses in north america and europe.the efficacy of an oral formulation of ivermectin plus praziquantel in the reduction of nematode and cestode egg counts in horses was assessed in 273 horses under field conditions at 15 sites in north america (n = 6) and europe (n = 9). horses were confirmed by fecal examination to have natural infections of strongyles (100%) and tapeworms (76%). replicates of four horses were formed at each site, and in each replicate three animals received ivermectin (0.2 mg/kg body weight) plus praziquantel ( ...200315136982
identification of major differences in the nucleocapsid protein genes of a québec strain and european strains of porcine reproductive and respiratory syndrome virus.the sequence of the 3'-terminal region of the genome of québec reference strain iaf-exp91 of porcine reproductive and respiratory syndrome virus (prrsv) was investigated by analysis of four cdna clones. the 3'-terminal 530 nucleotides (nt) encompassed a large open reading frame with a coding capacity of 123 amino acids (m(r) 13,649). the predicted protein was extremely basic and hence was considered to correspond to the nucleocapsid (n) protein gene. when compared to the homologous sequences of ...19948126467
prevalence of ulcers of the squamous gastric mucosa in standardbred horses.this study was performed to determine the prevalence of ulcers in the gastric squamous mucosa in standardbred racehorses. observations were performed at monthly intervals between the beginning of their training season and their 1st qualifying race. this study also identified risk factors at different levels of race training. forty-eight standardbred racehorses from 3 training stables in quebec, canada, were studied. baseline historical information and gastroscopic findings were recorded at the b ...200516231721

[prevalence of infections caused by salmonella spp. in cattle and horses at the veterinary teaching hospital of the faculty of veterinary medicine of the university of montreal].bacteriologic detection of salmonella spp. from feces of animals admitted to veterinary teaching hospital of the faculty of veterinary medicine, university of montréal, in saint-hyacinthe was carried out during a 1-year period to estimate the prevalence of bovine and equine salmonellosis. prevalence at the time of hospitalization was quite low: 1.4% in cattle and 1.7% in horses. incidence was 15.1 cases/100 animal/year in cattle and 38.7 cases/100 animal/year in horses. serotype typhimurium was ...19989752593
review of 40 cases of lung abscesses in foals and adult horses.a retrospective study of 40 horses with primary lung abscesses without pleuropneumonia showed that lung abscesses occurred predominantly in young horses, usually in foals aged < or = 6 months. hyperfibrinogenaemia was present in all but 2 horses, and other common clinical and haematological findings were hyperthermia, tachycardia, polypnoea, and neutrophilic leucocytosis. the most common bacterial species isolated from transtracheal aspirates were streptococcus zooepidemicus (20/34) and rhodococ ...19947988535
major antigenic groups of rabies virus in canada determined by anti-nucleocapsid monoclonal antibodies.a total of 123 rabies virus isolates from various geographical areas in canada were characterized by a panel of 43 anti-nucleocapsid monoclonal antibodies. four major antigenic groups are found in terrestrial mammals: "canadian arctic" from ontario, quebec and the northwest territories; "south-eastern georgian bay" from ontario; "south mid-central skunk" from alberta, saskatchewan and manitoba; and "brook's, alberta skunk" from a restricted area in alberta. bat isolates can be divided into 4 maj ...19863769442

a survey of exercise-induced pulmonary haemorrhage in quebec standardbred racehorses.sixty standardbred horses, aged 3 to 10 years, were examined endoscopically for exercise-induced pulmonary haemorrhage (eiph) 1 h after racing, on at least 3 occasions. racing time, finishing position and post exercise venous lactate concentrations were also recorded. horses positive for tracheal blood on endoscopy were classified as having either grade 1 eiph (one or a few spots of blood in the trachea), or grade 2 (stream of blood). air temperature, relative humidity and air pollutant levels w ...19947889923
