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. ...	1977	407202
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.	1977	924837

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 ...	1990	2280392
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 ...	1989	2505046
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 ...	1989	2585458
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 ...	1989	2764659
sarcocystis capracanis and toxoplasma gondii infections in range goats from texas.	specimens of tongues, esophagi, diaphragms, or abdominal muscles of 115 range goats from san angelo, tex, were examined for sarcocystis and toxoplasma gondii infections. sarcocystis spp zoites were found microscopically in pepsin digests of muscles of 60.8% goats and sarcocysts of s capracanis were found in histologic sections of 27.8% goats. sarcocysts were more common in sections of tongue (19.1%) than in those of other muscles (9.9% to 10.7%). a dog fed sarcocystis-infected tissues shed sporo ...	1986	3083732

sebaceous adenitis in the akita: clinical observations, histopathology and heredity.	ninety-seven pure-bred akitas were examined clinically and histologically for sebaceous adenitis. the diagnosis was established histologically in 23 akitas by demonstrating an inflammatory reaction targeted against the sebaceous glands or a reduction in the number of glands. the clinical course of sebaceous adenitis in the akita was similar to that seen in other breeds. the first skin lesions occurred mainly on the dorsal midline and ears. compared with the poodle, the age at first onset of the ...	2001	11906649
ownership of cats or dogs does not increase exposure to rickettsia typhi.	in the united states, murine typhus (rickettsia typhi) is endemic in southern california and south texas. evidence indicates the natural host/vector system is the opossum and cat flea, the most common flea on both cats and dogs, and speculation suggests that pet contact may pose a risk for r typhi exposure. serum from 140 subjects was tested for rickettsial antibodies by an enzyme-linked immunosorbent assay that used an r typhi antigen. each subject was asked about pet contact status and placed ...	2002	12073903
