1. Neutralising antibodies for Mayaro virus in Pantanal, Brazil
The Pantanal hosts diverse wildlife species and therefore is a hotspot for arbovirus studies in South America. A serosurvey for Mayaro virus (MAYV), eastern (EEEV), western (WEEV) and Venezuelan (VEEV) equine encephalitis viruses was conducted with 237 sheep, 87 free-ranging caimans and 748 equids, including 37 collected from a ranch where a neurologic disor

2. Neutralising antibodies for West Nile virus in horses from Brazilian Pantanal
Despite evidence of West Nile virus (WNV) activity in Colombia, Venezuela and Argentina, this virus has not been reported in most South American countries. In February 2009, we commenced an investigation for WNV in mosquitoes, horses and caimans from the Pantanal, Central-West Brazil. The sera of 168 horses and 30 caimans were initially tested using a flaviv

3. Systematization, description and territory of the middle and rostral cerebral arteries in broad-snouted caimans (Caiman latirostris)
Background: Information on the arterial vascularization of the broad-snouted caimans’ brain (Caiman latirostris), a specie from the Brazilian fauna, is inexistent and the literature consulted yielded only one description about the development of embryonic circulation and post-birth cerebrovascular alterations in the brain of three caymans. The objective of

4. Movimento e área de uso do jacaré-do-pantanal.
O estudo dos padrões de movimento dos jacarés do Pantanal ocorreu em uma área de lagos isolados e em uma área cortada por rios intermitentes no Pantanal. Foram marcados jacarés em 100 lagos, na área de lagos (1986-2001), e em 2 rios, na área de rios (1987-1999), recapturados 163 machos adultos, 132 fêmeas adultas e 237 jovens e monitorados 67 jacaré

5. Parentage test in broad-snouted caimans (Caiman latirostris, Crocodylidae) using microsatellite DNA
In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo, Brazil. Many of the females in the colony were full siblings, which made maternal identification diffic

6. Estructura poblacional y proporción de sexos en Caiman crocodilus en Caño Negro, Costa Rica
Evaluation of population status of Caiman crocodilus (Linnaeus, 1758) in Caño Negro Wildlife Refuge started in 1986. However, only information related with abundance and size of the population is known. The objective of this study was to evaluate population structure and sex ratio of C. crocodilus. We captured 145 caimans in 22 nocturnal spotlight surveys f

7. Diversidade morfológica e molecular e filogenia de isolados brasileiros de tripanossomas de cobras, jacarés e lagartos. / Morphological and molecular diversity and phylogeny of brazilian isolates of trypanosomes from snakes, caimans and lizards.
Tripanossomas de répteis há muito são descritos em lagartos, tartarugas, crocodilos e cobras de todos os continentes. A classificação destes tripanossomas tem sido feita de acordo com a morfologia de formas sanguíneas e hospedeiro de origem. No entanto, estes critérios tradicionais não são suficientes para descrição de espécies, gerando varias si

8. PADRÕES DE MOVIMENTO, USO DE MICROHÁBITAT E DIETA DO JACARÉ- PAGUÁ, PALEOSUCHUS PALPEBROSUS(CROCODILIA: ALLIGATORIDAE), EM UMA FLORESTA DE PALEOVÁRZEA AO SUL DO RIO SOLIMÕES, AMAZÔNIA CENTRAL, BRASIL
Survey based on nocturnal counts of Paleosuchus palpebrosus along dry and rainy season were made in flooded forest areas, streams and pounds in the edge of the highway BR-319, kilometer 80, approximately 100 km south of Manaus in the municipal district of Castanho - Central Amazon, for determination of movement patterns, microhabitat use and diet of the spec

9. Cross-species microsatellite amplification in South American Caimans (Caiman spp and Paleosuchus palpebrosus)
Microsatellite DNA markers have been used to assess genetic diversity and to study ecological behavioral characteristics in animals. Although these markers are powerful tools, their development is labor intensive and costly. Thus, before new markers are developed it is important to prospect the use of markers from related species. In the present study we inv

10. Development of Hepatozoon caimani (Carini, 1909) Pessôa, De Biasi & De Souza, 1972 in the Caiman Caiman c. crocodilus, the frog Rana catesbeiana and the mosquito Culex fatigans
The sporogony of Hepatozoon caimani has been studied, by light microscopy, in the mosquito Culex fatigans fed on specimens of the caiman Caiman c. crocodilus showing gametocytes in their peripheral blood. Sporonts iniciate development in the space between the epithelium of the insect gut and the elastic membrane covering the haemocoele surface of the stomach

11. Efeito do habitat na fecundidade das fêmeas, sobrevivência e razão sexual dos jovens de jacarés-do-pantanal.
A fecundidade das fêmeas, sobrevivência dos ovos e a razão sexual dos filhotes recém-eclodidos de Caiman crocodilus yacare foram estudados nas fazenda Nhumirim (área de lagos) e Campo Dora (área de rios intermitentes) no Pantanal. As fêmeas reprodutivas foram maiores na área de rios intermitentes do que na área de lagos. O número médio de ovos foi

12. Comportamento de termorregulação do jacaré-do-pantanal, Caiman crocodilus yacare.
A temperatura corpórea de 51 jacarés do Pantanal foi monitorada nos períodos de frio e calor em áreas de lagos e rios. A massa corpórea desses jacarés variou de 2 a 42 kg e seu tamanho afetou a temperatura média e a amplitude corpórea. A temperatura média corpórea alcançou 25oC, na estação fria, e 30oC, na estação quente, com valor mínimo de
