naturally occurring trypanosomiasis (chagas' disease) in dogs.nine fatal cases of canine american trypanosomiasis (chagas' disease) were encountered from november, 1972, through november, 1975. of the 9 cases, 7 occurred in dogs from 5 central texas counties, and all but one case was diagnosed during the months of september, october, or november. the source of infection was discovered in only one case--that being a doghouse heavily infested with triatoma lectularius occulta. each of 6 bugs collected had infective forms of the protozoan, trypanosoma cruzi. ...1977407202
accidental exposure of veterinary students to rabies.accidental exposure to rabies occurred in more than 200 veterinary students at texas a&m university from 1970 to 1977. few of the animals to which the students were exposed had typical signs of rabies prior to the exposures. an accelerated preexposure rabies prophylaxis program coupled with retention of suspect tissues suitable for fluorescent antibody procedures has reduced the number of postexposure prophylaxis series.1977924837

rabies surveillance in the united states during 1991.in 1991, 49 states, the district of columbia, and puerto rico reported 6,972 cases of rabies in nonhuman animals and 3 cases in human beings to the centers for disease control. ninety-one percent (6,354 cases) were wild animals, whereas 8.9% (618 cases) were domestic species. the total number of reported cases of rabies increased 42.9% over that of 1990 (4,881 cases), with most of the increase resulting from continued spread of the epizootic of rabies in raccoons in the mid-atlantic and northeas ...19921483899
pulmonary dirofilariasis. the largest single-hospital experience.pulmonary dirofilariasis caused by dirofilaria immitis, the dog heartworm, is a rarely reported pulmonary lesion. it most often appears as a solitary pulmonary nodule, often mistaken for a primary or metastatic lung tumor, and the diagnosis is not often established until thoracotomy with excisional lung biopsy is performed. sporadic reports of pulmonary dirofilariasis in the united states total only 87 cases. the ten resections of pulmonary dirofilariasis at the methodist hospital in houston, te ...19921516414

additional instances of human parasitism by the brown dog tick (acari: ixodidae).nine cases of humans parasitized by the brown dog tick, rhipicephalus sanguineus (latreille), are reported. eight cases occurred during 1989. seven of the individuals were from an apparent focus of human biting in northern texas and southwestern oklahoma, one case was from san antonio, bexar county, tex., and one case was from homestead air force base, dade county, fla. these cases suggest that the role of r. sanguineus in the transmission of the etiologic agent of canine ehrlichiosis and other ...19902280392
rabies surveillance, united states, 1988.the primary purpose of the annual report on rabies surveillance is to assist local and state public health officials in the planning of rabies control programs and to guide health professionals in evaluating the need for rabies postexposure prophylaxis in patients who are exposed to animals that may be rabid. in 1988, a total of 4,724 cases of animal rabies were reported by 47 states, the district of columbia, and puerto rico, similar to the total (4,729) for 1987. no human cases of rabies were ...19892505046
focus of human parasitism by the brown dog tick, rhipicephalus sanguineus (acari: ixodidae).throughout most of its range, the brown dog tick, rhipicephalus sanguineus (latreille), prefers dogs as a host, but human bites occasionally occur in the mediterranean region and central america; historically, this species has rarely bitten humans in the united states. a focus of 15 human bite cases by this tick is reported from four air force bases located within 200 miles of each other in north central texas and southwestern oklahoma. the sudden appearance of numerous documented bite cases ind ...19892585458
leptospirosis. epidemiological features of a sporadic case.leptospirosis occurred in a 45-year-old man with presumed infection from an exposure to contaminated water at his source of employment. an intensive epidemiological investigation, including serological examination of all family members and pets and cultures on the patient and his family pets (cats and dogs), proved that the leptospiral organism was acquired by the patient's exposure to his dogs. the risk of acquiring infection from dogs that are asymptomatic and vaccinated is emphasized by this ...19892764659
sarcocystis arieticanis and other sarcocystis species in sheep in the united states.histological sections of tongues, esophagi, and diaphragms from 512 adult ewes from the northwest united states and texas were examined for sarcocystis spp. sarcocysts were found in sections of 82.1% of 504 tongues, 44.4% of 478 esophagi, and 51.7% of 89 diaphragms. sarcocystis tenella was the predominant species and was found in 430 (84.0%) sheep; s. arieticanis was found in 18 (3.5%) sheep. the mean number of s. tenella sarcocysts in tissue sections was approximately 10 times higher than that ...19883142990

hepatozoon sp. in wild carnivores in texas.twelve coyotes (canis latrans), three bobcats (lynx rufus) and six ocelots (felis pardalis) from the gulf coast of texas were infected with hepatozoon sp. the geographic distribution of infected wild animals coincides with the highest prevalence of hepatozoon canis infection in domestic dogs for which the wild species may act as a reservoir.19883411720
endemic canine and feline histoplasmosis in el paso, texas.seventeen cases of histoplasmosis involving 2 dogs and 15 cats have occurred in the upper rio grande valley of el paso since 1978. the diagnosis, based on clinical signs and radiographic findings, was confirmed by one or more of the following laboratory procedures: demonstration of intracellular histoplasma capsulatum yeast cells in tissue, positive serology, or isolation of h. capsulatum from various organs of necropsied animals. h. capsulatum was isolated also from a bat cave and soil in the v ...19863701541
dermal leishmaniasis in a texas cat.leishmaniasis was diagnosed by demonstrating amastigotes of leishmania from dermal lesions on the ear of a male long-haired domestic cat from uvalde, texas. leishmania from the cat were propagated in syrian hamsters, bovine macrophages, and in nnn medium. the organism, in the l. mexicana complex, is apparently the same as that reported from recent human cases in the same area.19863789264
