Anurans as paratenic hosts in the transmission of Hepatozoon caimani to caimans Caiman yacare and Caiman latirostris

Parasitology Research, 2011
Prevalence of Hepatozoon caimani has been reported in 76% of caimans Caiman yacare from the Pantanal region. Culex (Melanoconion) spp. mosquitoes were recently identified as natural vectors of this parasite. However, culicids are not typically eaten by crocodilians, suggesting that the main transmission route is through ingestion of insectivorous ...

CEPHALOSPORIOSIS IN THREE CAIMANS

Journal of Wildlife Diseases, 1972
A fatal diffuse granulomatous pneumonia and focal necrotizing hepatitis were found at necropsy of three 6-month old caimans. Centers of the widely disseminated, discrete lesions in the lungs had a branching fungus with septate hyphae, chlamydospores, and elliptical and cigar-shaped conidia.

Allometry of Reproduction in Wild Broad-Snouted Caimans (Caiman latirostris)

Journal of Herpetology, 2004
We studied 20 nesting female Caiman latirostris and their clutches in Santa Fe Province, Argentina. We regressed clutch and egg parameters and hatchling size with several measurements of female size (ln-transformed) to evaluate the allometry of reproduction in the wild. Larger females produced relatively smaller clutches. Larger females produced larger

Detection of Leptospira spp. in Captive Broad-Snouted Caiman (Caiman latirostris)

EcoHealth, 2019
Leptospira sp. is an important waterborne zoonotic bacterium, known to cause infection in animals and humans worldwide. The role of reptiles in the transmission of this microorganism is poorly understood and historically neglected. This study aimed to investigate the presence of anti-Leptospira spp.

The Hearing of the Caiman, Caiman crocodilus

1990
The caiman is an alligator which, together with the crocodiles and gavials, form the few remaining reptilian descendents of the huge group of ruling diapsid reptiles of the Mesozoic period, the archosaurs (Fig. 1.2). They are closely related to the birds, a relationship which is immediately apparent in a comparison of the structure of the inner ear ...

Caiman yacare

Yacare Caiman, Caiman yacare (Daudin, 1802) Two skulls of individuals hunted locally at the Prefectura Naval de Pozo Hondo (22°18’30.3”S 62°31’53.5”W) (one collected CZPLT-H 2443, Fig. 26) document the species presence in the northern reaches of the Paraguayan Pilcomayo River, and represents the first specimen of the species from Boquerón department ...

Retinofugal projections of Caiman sklerops

Experimental Neurology, 1967
Abstract The retinofugal projections of the South American alligator, Caiman sklerops , were traced utilizing the Nauta-Gygax method. The results of this study confirm earlier work on the alligator which described direct retinal connections to the lateral geniculate nucleus of the thalamus, the nucleus lentiformis mesencephali of the pretectum and ...

Growth rates of black caiman Melanosuchus niger and spectacled caiman Caiman crocodilus, and the recruitment of breeders in hunted caiman populations

Biological Conservation, 1991
Abstract Hunted populations of black caiman Melanosuchus niger are unable to persist, but many hunted populations of spectacled caiman Caiman crocodilus appear to be maintaining their numbers. Previous authors explained these observations by noting that black and spectacled caiman differ in the length of time that individuals are highly ...

Antibodies against Leptospira spp. in Free-Living and Captive Broad-Snouted Caiman (Caiman latirostris) and Free-Living Yacare Caiman (Caiman yacare) in Brazil

Journal of Wildlife Diseases
We evaluated antibodies against Leptospira spp. in both free-living and captive Caiman latirostris from Atlantic Forest, and free-living Caiman yacare from Pantanal, Brazil, by using a microscopic agglutination test. Overall seropositivity was 17%, with rates of 36% in captive C. latirostris (n=4/11) and 18% in free-living C. yacare (n=4/22).
