characterization of pasteurella multocida isolated from rabbits in canada.in a survey for the somatic and capsular serotypes of pasteurella multocida present in domestic rabbits in canada, but mainly in ontario, samples were obtained from research facilities, commercial rabbitries and from abattoir and necropsy specimens. sources of isolates were upper respiratory tract infections, localized bronchopneumonias , acute fibrinous pneumonias, abscesses and otitis media. of 59 isolates obtained, 47.0% were type 12:a, 30.5% 3:d and 12.0% were 3:a. less common types were 12( ...19846722644
antimicrobial use in feedlot calves: its association with culture rates and antimicrobial susceptibility.data were collected on anti-microbial usage and health problems, in beef feedlot calves. although the association between them was not significant, many feedlot owners did not use recommended dosages or duration of treatment and this may have led to a reduced recovery rate.injectable tetracyclines were the most frequent antimicrobial for primary treatment of sick calves; whereas chloramphenicol was selected most frequently when the primary treatment appeared to be ineffective. treatment with ant ...19836831306
prevalence of zoonotic agents in dogs visiting hospitalized people in ontario: implications for infection control.visitation of hospitalized people by dogs is becoming commonplace, but little is known about the potential health risks of introducing dogs to healthcare settings. this cross-sectional study evaluated the prevalence of zoonotic agents in a group of 102 visitation dogs from a variety of sources across ontario. between may and july 2004, owners were interviewed by a standardized questionnaire while dogs underwent a standardized physical examination. one specimen of faeces, hair-coat brushings and ...200616466831
diseases and pathogens associated with mortality in ontario beef feedlots.this study determined the prevalence of diseases and pathogens associated with mortality or severe morbidity in 72 ontario beef feedlots in calves that died or were euthanized within 60 days after arrival. routine pathologic and microbiologic investigations, as well as immunohistochemical staining for detection of bovine viral diarrhea virus (bvdv) antigen, were performed on 99 calves that died or were euthanized within 60 days after arrival. major disease conditions identified included fibrinos ...200616566254
prevalence of actinobacillus pleuropneumoniae, actinobacillus suis, haemophilus parasuis, pasteurella multocida, and streptococcus suis in representative ontario swine herds.tonsillar and nasal swabs were collected from weanling pigs in 50 representative ontario swine herds and tested for the presence of 5 important bacterial upper respiratory tract pathogens. all but 1 herd (2%) tested positive for streptococcus suis by polymerase chain reaction (pcr); 48% of herds were s. suis serovar 2, 1/2 positive. in all but 2 herds there was evidence of haemophilus parasuis infection. in contrast, toxigenic strains of pasteurella multocida were detected by a p. multocida--enz ...200818505187
microbiological identification and analysis of swine tonsils collected from carcasses at slaughter.the primary objective of this 7-month study was to determine the prevalence of porcine pathogens of the tonsil of the soft palate of swine at slaughter. additional objectives were to determine if sampling the carcasses of normal or abnormal hogs provided different microbiological profiles and if the slaughter plant provides a feasible sampling frame and environment for detecting and monitoring important pathogens in tonsils that have health implications for both swine and humans. a total of 395 ...201121731180
antimicrobial susceptibility of escherichia coli f4, pasteurella multocida, and streptococcus suis isolates from a diagnostic veterinary laboratory and recommendations for a surveillance system.antimicrobial susceptibility data on escherichia coli f4, pasteurella multocida, and streptococcus suis isolates from ontario swine (january 1998 to october 2010) were acquired from a comprehensive diagnostic veterinary laboratory in ontario, canada. in relation to the possible development of a surveillance system for antimicrobial resistance, data were assessed for ease of management, completeness, consistency, and applicability for temporal and spatial statistical analyses. limited farm locati ...201424688133
multiple-class antimicrobial resistance surveillance in swine escherichia coli f4, pasteurella multocida and streptococcus suis isolates from ontario and the impact of the 2004-2006 porcine circovirus type-2 associated disease outbreak.the objective of this work was to describe trends in multiple-class antimicrobial resistance present in clinical isolates of escherichia coli f4, pasteurella multocida and streptococcus suis from ontario swine 1998-2010. temporal changes in multiple-class resistance varied by the pathogens examined; significant yearly changes were apparent for the e. coli and p. multocida data. although not present in the e. coli data, significant increases in multiple-class resistance within p. multocida isolat ...201424309129
mortality and disease in wild turkeys ( meleagris gallopavo silvestris) in ontario, canada, from 1992 to 2014: a retrospective review.wild turkeys ( meleagris gallopavo silvestris) were extirpated from ontario, canada, in the early 1900s due to unregulated over-hunting and habitat loss. despite a successful reintroduction program and strong population numbers, information regarding the health of wild turkeys in ontario is scarce. a 22-yr (1992-2014) retrospective study was performed to evaluate diagnostic data, including the cause(s) and contributors to death, in wild turkeys submitted to the ontario-nunavut node of the canadi ...201627610724
surveillance of antimicrobial resistance in clinical isolates of pasteurella multocida and streptococcus suis from ontario swine.susceptibility results for pasteurella multocida and streptococcus suis isolated from swine clinical samples were obtained from january 1998 to october 2010 from the animal health laboratory at the university of guelph, guelph, ontario, and used to describe variation in antimicrobial resistance (amr) to 4 drugs of importance in the ontario swine industry: ampicillin, tetracycline, tiamulin, and trimethoprim-sulfamethoxazole. four temporal data-analysis options were used: visualization of trends ...201425355992
