| tissue pathology and comparative microanatomy of onchocerca from a resident of ontario and other enzootic onchocerca species from canada and the u.s.a. | the microanatomy of one male and one female specimen of a zoonotic onchocera sp in a fibrous nodule excised from the wrist of an ontario resident, two bovine onchocerca from saskatchewan and manitoba, canada, and o. cervicalis from the ligamentum nuchae of a horse in georgia, u.s.a., were compared. in dimensions and cuticular morphology, the three canadian specimens of onchocera shared certain features and closely resembled both o. cervicalis and o. gutturosa. the number of cuticular striae in s ... | 1977 | 596957 |

| the host preferences of culiseta inornata in southwestern manitoba. | the capillary tube precipitin test was used to determine the host utilization patterns of culiseta inornata in southwestern manitoba. ruminant blood was identified in 83.3% and equine blood in 15.8% of 1,036 positively reacting blood-meals. human, swine and avian blood accounted for 0.9% of these blood-meals and mixed blood-meals accounted for 1.5% of the total. culiseta inornata preferentially fed on large mammals, and selection between cattle and horses reflected the relative abundance of thes ... | 1987 | 2904945 |
| impact of climate on western equine encephalitis in manitoba, minnesota and north dakota, 1980-1983. | information was collected on confirmed outbreaks of western equine encephalitis (wee) in north america east of the rockies for 1981 and 1983 (epidemic years) and 1980 and 1982 (non-epidemic years). the initial pattern of outbreaks in manitoba, minnesota and north dakota was determined for each year. backward (and in some instances forward) wind trajectories were computed for each day 4-15 days (incubation period) before the initial outbreaks of wee in a given area of province or state. during th ... | 1988 | 2905669 |
| amplified elisa for the detection of western equine encephalitis virus from mosquitoes in manitoba, canada. | current monitoring systems to detect western equine encephalitis (wee) virus in mosquitoes involve isolation in suckling mice or cell culture followed by serological identification of the isolates obtained. studies were undertaken to develop an amplified elisa for the rapid detection of wee virus from mosquitoes. virus was inoculated onto primary chick embryo cells in 96 well plates, incubated at 37 degrees c for various time periods, monolayers were fixed, and an elisa performed. by this proced ... | 1987 | 3443681 |
| 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 ... | 1986 | 3769442 |

| weather factors in the prediction of western equine encephalitis epidemics in manitoba. | cases of western equine encephalitis in horses in 1987 in western usa and manitoba, canada were examined by backward trajectory analysis of winds. culex tarsalis mosquitoes infected with western equine encephalitis virus could have been carried on southerly winds from texas and oklahoma to northern usa and from there to manitoba. the presence of the polar front over north dakota and minnesota at the end of july would have led to the landing of cx. tarsalis in montana and wisconsin and prevented ... | 1993 | 8405163 |
| risk factors associated with the incidence of foal mortality in an extensively managed mare herd. | the purpose of this study was to determine the incidence of neonatal mortality in a large, extensively managed mare herd and what risk factors were involved in foal mortality. for a 6 wk period between april 18, 1994, and may 31, 1994, 334 foals were born, of which 74 died before reaching 10 d of age, giving an overall mortality of 22% for this period. seventy four percent of the foal deaths occurred within 48 h of parturition. the major causes of foal mortality included starvation/exposure 27%, ... | 1996 | 8640655 |
| anesthetic gas exposure in veterinary clinics. | concerns were raised by several workers from veterinary clinics in manitoba, canada, regarding potential exposure to isoflurane and halothane during anesthetic administration. there has been no guideline established for isoflurane by the american conference of governmental industrial hygienist (acgih) or a permissible exposure limit by the occupational safety and health administration (osha) or a recommended exposure limit (rel) by the national institute for occupational safety and health (niosh ... | 1999 | 10429733 |
| prevalence of antibodies to neospora caninum, sarcocystis neurona, and toxoplasma gondii in wild horses from central wyoming. | sarcocystis neurona, neospora caninum, n. hughesi, and toxoplasma gondii are 4 related coccidians considered to be associated with encephalomyelitis in horses. the source of infection for n. hughesi is unknown, whereas opossums, dogs, and cats are the definitive hosts for s. neurona, n. caninum, and t. gondii, respectively. seroprevalence of these coccidians in 276 wild horses from central wyoming outside the known range of the opossum (didelphis virginiana) was determined. antibodies to t. gond ... | 2003 | 14533680 |
| chronically starved horses: predicting survival, economic, and ethical considerations. | nine of 45 horses subjected to prolonged malnutrition died subsequent to being placed with a responsible caregiver and being provided an appropriate diet. initial extreme poor body condition score tended to be associated with death, although individual response to refeeding varied. the financial costs of stabilizing the group of horses significantly exceeded their free market price. responsible management of chronically starved commercial animals should include options for immediate euthanasia. | 2005 | 15943117 |
