vaccine-associated canine distemper infection in a litter of african hunting dogs (lycaon pictus).four, 57 days old, african hunting dog puppies (lycaon pictus) from one litter died within three weeks following vaccination with modified-live canine distemper virus (cdv) and killed canine adenovirus type 1, canine parvovirus and leptospira icterohemorrhagiae and canicola. 18 days post vaccination, the animals developed neurologic disease characterized by episodes of grand mal seizures and circling. macroscopic, histological and immunohistochemical studies revealed acute systemic cdv infection ...19902385981
serosurvey for selected viral diseases and demography of african wild dogs in tanzania.african wild dogs (lycaon pictus) are endangered, with only 3,000-5,000 remaining in the wild. it is believed that wild dogs are unusually vulnerable to viral diseases, particularly rabies and canine distemper (cdv). however, canine distemper has been confirmed by laboratory diagnosis in only one free-living wild dog. the 43,000 km2 selous game reserve (sgr; tanzania) holds approximately 900 adult wild dogs. in a study area of 2,600 km2, the population maintained high density (> or = 1 dog/20.5 ...19979391968
seroepidemiological survey of sympatric domestic and wild dogs (lycaon pictus) in tsumkwe district, north-eastern namibia.disease is a potential threat to many endangered populations and may originate from sympatric domestic species. this paper describes a cross-sectional serological survey of canine pathogens carried out in domestic (n = 70) and wild dogs (lycoan pictus) (n = 6), in tsumkwe district, northeastern namibia. evidence of past exposure to canine distemper virus, canine adenovirus and parainfluenza virus was evident in both wild and domestic dogs with this, the first, documented exposure of free-living ...19979551484
clinical and serological response of wild dogs (lycaon pictus) to vaccination against canine distemper, canine parvovirus infection and rabies.wild dogs lycaon pictuis (n = 8) were vaccinated 4 times against canine distemper (n = 8) (initially with inactivated and subsequently with live attenuated strains of canine distemper) and canine parvovirus infection (n = 8) over a period of 360 days. four of the wild dogs were also vaccinated 3 times against rabies using a live oral vaccine and 4 with an inactivated parenteral vaccine. commercially-available canine distemper, canine parvovirus and parenteral rabies vaccines, intended for use in ...200212088076
fatal canine distemper infection in a pack of african wild dogs in the serengeti ecosystem, tanzania.in 2007, disease related mortality occurred in one african wild dog (lycaon pictus) pack close to the north-eastern boundary of the serengeti national park, tanzania. histopathological examination of tissues from six animals revealed that the main pathologic changes comprised interstitial pneumonia and suppurative to necrotizing bronchopneumonia. respiratory epithelial cells contained numerous eosinophilic intracytoplasmic inclusion bodies and multiple syncytial cells were found throughout the p ...201020684868
contact with domestic dogs increases pathogen exposure in endangered african wild dogs (lycaon pictus).infectious diseases have contributed to the decline and local extinction of several wildlife species, including african wild dogs (lycaon pictus). mitigating such disease threats is challenging, partly because uncertainty about disease dynamics makes it difficult to identify the best management approaches. serious impacts on susceptible populations most frequently occur when generalist pathogens are maintained within populations of abundant (often domestic) "reservoir" hosts, and spill over into ...201222238695
serological detection of infection with canine distemper virus, canine parvovirus and canine adenovirus in communal dogs from zimbabwe.domestic dogs are common amongst communities in sub-saharan africa and may serve as important reservoirs for infectious agents that may cause diseases in wildlife. two agents of concern are canine parvovirus (cpv) and canine distemper virus (cdv), which may infect and cause disease in large carnivore species such as african wild dogs and african lions, respectively. the impact of domestic dogs and their diseases on wildlife conservation is increasing in zimbabwe, necessitating thorough assessmen ...201425686382
duration of immunity in red wolves (canis rufus) following vaccination with a modified live parvovirus and canine distemper vaccine.there is growing information available regarding duration of immunity for core vaccines in both domestic and nondomestic species. vaccination protocols in nondomestic canids have frequently followed guidelines developed for the domestic dog; however, these protocols can be inappropriate for nondomestic canids such as the african wild dog (lycaon pictus), leaving some animals susceptible to infectious disease and others at risk for contracting vaccine-induced disease. in this study, red wolves (c ...201425314821
rabies, canine distemper, and canine parvovirus exposure in large carnivore communities from two zambian ecosystems.disease transmission within and among wild and domestic carnivores can have significant impacts on populations, particularly for threatened and endangered species. we used serology to evaluate potential exposure to rabies virus, canine distemper virus (cdv), and canine parvovirus (cpv) for populations of african lions (panthera leo), african wild dogs (lycaon pictus), and spotted hyenas (crocuta crocuta) in zambia's south luangwa national park (slnp) and liuwa plain national park (lpnp) as well ...201323805791
