morbidity-mortality factors and survival of an urban coyote population in arizona.the health of coyotes (canis latrans) in urban areas has not been studied. our objectives were to assess the health of coyotes in tucson (arizona, usa) by determining the prevalence of antibodies to selected pathogens, estimating survival rates, and identifying sources of mortality. we drew blood from 22 coyotes to evaluate the prevalence of heartworm (dirofilaria immitis) antigens, and antibodies to canine distemper virus (cdv), infectious canine hepatitis (ich), canine parvovirus (cpv), and se ...200111310882
trichinella infection in wildlife of the southwestern united states.several potential mammalian reservoirs of sylvatic species of trichinella were examined from texas, new mexico, and arizona. during 1998-99, tongues were collected from a black bear (ursus americanus) in arizona; from 9 black bears, a coyote (canis latrans), and a mountain lion (felis concolor) in new mexico; and from 154 coyotes, 32 raccoons (procyon lotor), 13 opossums (didelphis marsupialis), 4 ocelots (leopardus pardalis), 3 bobcats (lynx rufus), and 5 feral hogs (sus scrofa) in southern tex ...200111695403
rabies surveillance in the united states during 2001.during 2001, 49 states and puerto rico reported 7,437 cases of rabies in nonhuman animals and 1 case in a human being to the centers for disease control and prevention, an increase of < 1% from 7,364 cases in nonhuman animals and 5 human cases reported in 2000. more than 93% (6,939 cases) were in wild animals, whereas 6.7% (497 cases) were in domestic species (compared with 93.0% in wild animals and 6.9% in domestic species in 2000). the number of cases reported in 2001 increased among bats, cat ...200212494966
fatal footsteps: murder of undocumented border crossers in maricopa county, the past 5 years, the mortality rate among undocumented workers in arizona has increased steadily. in 1998-1999, the number of deaths among border crossers was 28. that number increased dramatically in 1999-2000 to 106 and has exceeded 200 in each of the past 2 years. in the past, many immigrant deaths occurred as a result of dehydration and exposure (1). more recently, a new trend has emerged, that is, death of border crossers at the hands of the persons ("coyotes") hired to lead them across ...200818279237
seroprevalence of trypanosoma cruzi among eleven potential reservoir species from six states across the southern united states.trypanosoma cruzi, the causative agent of chagas' disease, is a substantial public health concern in latin america. although rare in humans and domestic animals in the united states, t. cruzi is commonly detected in some wildlife species, most commonly raccoons (procyon lotor) and virginia opossums (didelphis virginiana). to increase our understanding of the reservoir host species range and geographic distribution, 11 species of mammals from six states spanning the known range of t. cruzi (arizo ...201020020815
annual seroprevalence of yersinia pestis in coyotes as predictors of interannual variation in reports of human plague cases in arizona, united states.abstract although several health departments collect coyote blood samples for plague surveillance, the association between reported human cases and coyote seroprevalence rates remains anecdotal. using data from an endemic region of the united states, we sought to quantify this association. from 1974 to 1998, about 2,276 coyote blood samples from four arizona counties were tested for serological evidence of exposure to yersinia pestis, the causative agent of plague. using a titer threshold presum ...201121756031
prevalence and characterization of escherichia coli and salmonella strains isolated from stray dog and coyote feces in a major leafy greens production region at the united states-mexico 2010, romaine lettuce grown in southern arizona was implicated in a multi-state outbreak of escherichia coli o145:h28 infections. this was the first known shiga toxin-producing e. coli (stec) outbreak traced to the southwest desert leafy green vegetable production region along the united states-mexico border. limited information exists on sources of stec and other enteric zoonotic pathogens in domestic and wild animals in this region. according to local vegetable growers, unleashed or stray d ...201425412333
captive breeding and the reintroduction of mexican and red wolves.mexican and red wolves were both faced with extinction in the wild until captive populations were established more than two decades ago. these captive populations have been successfully managed genetically to minimize mean kinship and retain genetic variation. descendants of these animals were subsequently used to start reintroduced populations, which now number about 40-50 mexican wolves in arizona and new mexico and about 100 red wolves in north carolina. the original captive mexican wolf popu ...200818173506
