| serological characterization of actinobacillus pleuropneumoniae strains isolated from pigs in quebec. | a total of 3306 isolates of a. pleuropneumoniae originating from lung tissues of pigs that died of acute pleuropneumonia and 140 isolates recovered from tonsils or nasal cavities of apparently healthy pigs from chronically infected herds were serotyped. various serotyping methods, such as slide agglutination, tube agglutination, ring precipitation, coagglutination, immunodiffusion, indirect hemagglutination and counterimmunoelectrophoresis either alone or in combination were used. the techniques ... | 1992 | 1441197 |
| changes in the susceptibility of actinobacillus pleuropneumoniae to antimicrobial agents in quebec (1981-1986). | an important reduction in the in vitro efficacy of spectinomycin and chloramphenicol was recorded between 1981 and 1986 against the causal agent of porcine pleuropneumonia actinobacillus. antimicrobial susceptibility tests were carried out by use of kirby-bauer disk diffusion technique on a total of 723 isolates of actinobacillus pleuropneumoniae. results did not agree with those of other reports in which a constant susceptibility to any of the antimicrobial agents tested was reported with serot ... | 1988 | 3170322 |
| mycoplasmosis in evening and pine grosbeaks with conjunctivitis in quebec. | an outbreak of conjunctivitis affected evening grosbeaks (coccothraustes vespertinus) and pine grosbeaks (pinicola enucleator) in quebec (canada) during the winter 1998-99. one to 30% of the individuals from these two species were sick at 13 feeding stations. sick birds were thin and had unilateral or bilateral catarrhal and lymphoplasmacytic conjunctivitis and rhinitis, and mucopurulent infra-orbital sinusitis. mycoplasmal organisms were isolated in cultures in an affected evening grosbeak and ... | 2001 | 11763749 |
| otitis media in dairy calves: a retrospective study of 15 cases (1987 to 2002). | epidemiological data, clinical signs, complementary examination findings, antimicrobial treatments, and outcome were reviewed in 15 calves diagnosed with otitis media at the centre hospitalier universitaire vétérinaire de l'université de montréal between 1987 and 2002. age at presentation ranged from 2 to 18 weeks. a purulent ear discharge and epiphora were seen in 8/12 and 6/15 cases, respectively. neurological signs observed were head tilt (13), eyelid ptosis (7), paresis/paralysis of the pinn ... | 2004 | 15368739 |
| the emergence of porcine circovirus 2b genotype (pcv-2b) in swine in canada. | since late 2004, the swine industry in the province of quebec has experienced a significant increase in death rate related to postweaning multisystemic wasting syndrome (pmws). to explain this phenomenon, 2 hypotheses were formulated: 1) the presence of a 2nd pathogen could be exacerbating the porcine circovirus 2 (pcv-2) infection, or 2) a new and more virulent pcv-2 strain could be infecting swine. in 2005, 13 pmws cases were submitted to the quebec provincial diagnostic laboratory and pcv-2 w ... | 2007 | 17824323 |
| 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 ... | 1994 | 7988535 |
| efficacy of tilmicosin in the control of experimentally induced actinobacillus pleuropneumoniae infection in swine. | the efficacy of tilmicosin administered in the feed to control actinobacillus pleuropneumoniae infections in pigs was evaluated through a multisite, multitrial study. for each of 6 trials, 48 pigs (stratified by weight and sex) were randomly assigned to 6 to 8 pens. medicated feed containing tilmicosin (200 g/t) and unmedicated feed were randomly assigned at the pen level and were provided ad libitum from day -7 to trial termination (day 14). seeder pigs (inoculated intranasally with a. pleuropn ... | 2004 | 14979429 |

| management practices associated with the bulk-milk prevalence of staphylococcus aureus in canadian dairy farms. | when designing mastitis-prevention and control programs, it is important to know the level of adoption of mastitis-prevention management practices and control programs and the herd-level prevalence of contagious mastitis pathogens. our objectives were to estimate: (1) adoption of recommended mastitis-preventive management on canadian dairy farms; (2) herd-level prevalence of contagious mastitis pathogens on canadian dairy farms; and (3) associations of certain management practices with the isola ... | 2010 | 20696486 |
