| cutaneous leishmaniasis of man due to leishmania (viannia) shawi lainson, de souza, póvoa, ishikawa & silveira, in pará state, brazil. | leishmania (viannia) shawi lainson, braga, de souza, póvoa, ishikawa & silveira, 1989, was originally recorded from monkeys (cebus apella and chiropotes satanas), sloths (choloepus didactylus and bradypus tridactylus) and coatis (nasua nasua) and the sandfly, lutzomyia whitmani. with a panel of leishmania specific monoclonal antibodies, it was found that 30.5% of the leishmania strains from patients, who had contracted cutaneous leishmaniasis in pará state, were similar, but not identical to l. ... | 1991 | 1822654 |
| vertebrate hosts and vectors of trypanosoma rangeli in the amazon basin of brazil. | a total of 46 trypanosoma rangeli stocks were isolated from naturally infected mammals and triatomine vectors. twenty-two stocks were from the common opossum (didelphis marsupialis), one from the brown "4-eyed" opossum (metachirus nudicaudatus), one from the anteater (tamandua tetradactyla), one from the coati (nasua nasua), seven from rhodnius pictipes and 14 from rhodnius robustus. two stocks were also isolated from recently fed sandflies (lutzomyia sp., shannoni group). the stocks were identi ... | 1983 | 6418015 |
| collection and evaluation of semen from the three-toed sloth (bradypus tridactylus). | sloths (bradypus sp.) are extremely sensitive animals that suffer with the destruction and fragmentation of forests. they present a low population growth rate and need to be further studied for the preservation of the specie. thus, the aim of this study was to establish an efficient semen collection protocol as well as characterize sperm concentration, motility and morphology in order to contribute with information about the reproductive traits of this specie, which has never been described in t ... | 2008 | 18417178 |
| pneumocystis and histoplasma infections in wild animals from the amazon region of brazil. | routine examination of tissues from wild forest rodents from amapá, north brazil, revealed pneumocystis carinii in lung smears from a newly captured oryzomys capito (cricetidae). acute, fatal infections with this parasite are also recorded in a number of captive "coatimundis", nasua narica (carnivora: procyonidae) and a sloth, bradypus tridactylus (edentata). pneumocystis was also encountered in lung smears from a newly captured and apparently healthy sloth, choloepus didactylus. the presence of ... | 1975 | 1084602 |
| brazilian distribution of amblyomma varium koch, 1844 (acari: ixodidae), a common parasite of sloths (mammalia: xenarthra). | amblyomma varium, commonly known in brazil as the "carrapato-gigante-da-pregui a" (sloth's giant tick) is found from southern central america to argentina. the present study adds information on the geographical distribution of a. varium, as well as on their hosts, based on material deposited in the main brazilian collections and on the available literature. eighty-two vials, containing 191 adult specimens, deposited in five acari collections between 1930 and 2001, were examined. these vials incl ... | 2003 | 12563481 |
| novel anaplasma and ehrlichia organisms infecting the wildlife of two regions of the brazilian amazon. | during 2009-2012, wild animals were sampled in the amazon biome of brazil. animal tissues and blood were tested by polymerase chain reaction (pcr) assays targeting dna of the bacterial family anaplasmataceae (genera anaplasma, ehrlichia, wolbachia) and the genus borrelia. overall, 181 wild animals comprising 36 different species (2 reptiles, 5 birds, and 29 mammals) were sampled. all birds and reptiles were negative by all pcr assays, as well as all mammals for the borrelia pcr assay. anaplasmat ... | 2017 | 28690147 |
