RESUMO
Brazil concentrates the largest number of primate species in the world. In the present study, an extensive literature review of ticks on New World wild monkeys has been carried out, demonstrating that between the years 1912 to 2018, 182 larvae, 137 nymphs and 31 adult ticks (10 males and 21 females) were collected on 78 primates (from 12 different species) in 28 distinct localities in the Brazilian territory. Additionally, examination of allotments of 11 tick collections of Brazil revealed that from 1919 to 2019, 93 larvae, 91 nymphs and 175 adult ticks (62 males and 113 females) were collected from 100 monkeys (among 20 different species) from 43 localities in distinct Brazilian biomes. Overall, 19 tick species were identified on wild primates in the country: Amblyomma aureolatum (Pallas, 1772), Amblyomma cajennense (Fabricius, 1787) sensu stricto, Amblyomma coelebs Neumann, 1899, Amblyomma dubitatum Neumann, 1899, Amblyomma geayi Neumann, 1899, Amblyomma incisum Neumann, 1906, Amblyomma longirostre (Koch, 1844), Amblyomma naponense (Packard, 1869), Amblyomma nodosum Neumann, 1899, Amblyomma ovale Koch, 1844, Amblyomma parkeri Fonseca & Aragão, 1952, Amblyomma romarioi Martins, Luz & Labruna, 2019, Amblyomma rotundatum Koch, 1844, Amblyomma sculptum Berlese, 1888, Haemaphysalis juxtakochi Cooley, 1946, Ixodes fuscipes Koch, 1844, Rhipicephalus microplus (Canestrini, 1888), Rhipicephalus sanguineus (Latreille, 1806) sensu lato,and Ornithodoros rostratus Aragão, 1911. The presence of A. incisum, A. naponense, A. nodosum, A. rotundatum and I. fuscipes on monkeys is recorded for the first time. Thisresearch is therefore a significant contribution to the knowledge of tick speciesassociated with non-human primates in the Neotropical region.
RESUMO
The aim of this study was to describe a fatal salmonellosis case in a non-human female primate (Callithrix jacchus), found in the illegal pet trade in Brazil. The marmoset was sent to the quarantine section of the Guarulhos City Zoo and died in the sequence of an episode of profuse diarrhea. Necropsy findings included mucous enteritis, and liver enlargement and necrosis. Feces and liver fragments were collected for bacteriological tests, which indicated the presence of Salmonella sp.; it was subsequently characterized as pertaining to the Yoruba serotype. The susceptibility profile demonstrated resistance to tetracycline only. The strain was positive for genes that encoded the virulence factors investigated (invA, sefC, pefA and spvC). The results indicated the risk of introduction of Salmonella pathogenic serotypes in primates in captivity.
O objetivo deste trabalho foi descrever um caso fatal de salmonelose em uma fêmea primata não humana (Callithrix jacchus), originária de tráfico ilegal no Brasil. O sagui foi enviado para seção de quarentena do Zoológico Municipal de Guarulhos e morreu após um episódio de diarréia profusa. Achados de necropsia incluíram enterite mucosa, hepatomegalia e necrose do fígado. Fezes e fragmentos do fígado foram coletados para testes bacteriológicos e indicaram a presença de Salmonella sp.; subsequentemente caracterizada como sorotipo Yoruba. O perfil de suscetibilidade mostrou resistência somente à tetraciclina. A cepa foi positiva para os genes que codificam os fatores de virulência investigados (invA, sefC, pefA and spvC). Os resultados indicaram o risco de introdução de sorotipos patogênicos de Salmonella por primatas em cativeiro.
