| rickettsia honei: a spotted fever group rickettsia on three continents. | rickettsia honei (also known as strain tt-118) has been detected on three continents. originally isolated in thailand in 1962 (and confirmed in 2001), it has also been detected on flinders island (australia) in 1993 and in texas (usa) in 1998. on each continent it has been associated with a different species of tick. the original isolate (thai tick typhus strain tt-118) was from a pool of larval ixodes and rhipicephalus ticks. later it was detected in i. granulatus from rattus rattus. its pathog ... | 2003 | 12860601 |
| differences in biological characteristics of two strains of the cestode hymenolepis diminuta. | biological characteristics of infectivity, growth rate and fecundity of hymenolepis diminuta isolated from wild rattus rattus in japan were compared with parasites of texas origin maintained for several generations in this and many other laboratories in laboratory bred rattus norvegicus. the timing of development and maturation was similar in parasites from both sources, but the mean parasite dry weight was less and the mean egg production lower in japanese parasites in both single and multiple ... | 1987 | 3670903 |
| observations on the involvement of wildlife in an epornitic of chlamydiosis in domestic turkeys. | in an investigation of potential wildlife reservoirs of chlamydia psittaci at the site of an acute, highly fatal epornitic of chlamydiosis in domestic turkeys in texas, various species of wild birds and rodents were captured and tested for chlamydial serum antibodies and chlamydiae in their tissues. thirteen (65%) of 20 blackbirds (agelaius sp), 4 (44%) of 9 killdeer (oxyechus vociferus), 3 (27%) of 11 sparrows (passer sp) and 1 of 4 mourning doves (zenaidura macroura) were seropositive, but chl ... | 1976 | 988009 |
| murine typhus: an unrecognized suburban vectorborne disease. | murine typhus, an acute febrile illness caused by rickettsia typhi, is distributed worldwide. mainly transmitted by the fleas of rodents, it is associated with cities and ports where urban rats (rattus rattus and rattus norvegicus) are abundant. in the united states, cases are concentrated in suburban areas of texas and california. contrary to the classic rat-flea-rat cycle, the most important reservoirs of infection in these areas are opossums and cats. the cat flea, ctenocephalides felis, has ... | 2008 | 18260783 |
| southern plains woodrats (neotoma micropus) from southern texas are important reservoirs of two genotypes of trypanosoma cruzi and host of a putative novel trypanosoma species. | trypanosoma cruzi, the causative agent of chagas' disease, is an important public health and veterinary pathogen. although human cases are rare in the united states, infections in wildlife, and in some areas domestic dogs, are common. in 2008 and 2010, we investigated t. cruzi prevalence in possible vertebrate reservoirs in southern texas, with an emphasis on southern plains woodrats (neotoma micropus). infection status was determined using a combination of culture isolation, polymerase chain re ... | 2013 | 23127189 |
| lack of trypanosoma cruzi infection in urban roof rats (rattus rattus) at a texas facility housing naturally infected nonhuman primates. | the protozoan parasite trypanosoma cruzi causes chagas disease, uses kissing bugs as a vector, and is maintained in nature by a variety of wildlife reservoirs. many natural cases of chagas disease have been reported in nhp at facilities across the southern united states, where infected vectors and wildlife occur. infection of nhp with t. cruzi can diminish their value as research models and lead to health problems and death. identifying the modes of transmission and role of wildlife reservoirs i ... | 2017 | 28905716 |
