Cross-species microsatellite amplification in South American Caimans (Caiman spp and Paleosuchus palpebrosus)
Provedor de dados: 74
Autores: Zucoloto,Rodrigo Barban; Villela,Priscilla Marqui Schimidt; Verdade,Luciano Martins; Coutinho,Luiz Lehmann.
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 investigated the possibility of using microsatellite markers developed for Alligator mississipiensis and Caiman latirostris in South American crocodilians. Our results demonstrate the use of microsatellite markers for Paleosuchus palpebrosus, Caiman crocodilus and Caiman yacare.

Parentage test in broad-snouted caimans (Caiman latirostris, Crocodylidae) using microsatellite DNA
Provedor de dados: 74
Autores: Zucoloto,Rodrigo B.; Verdade,Luciano M.; Villela,Priscilla M.S.; Regitano,Luciana C.A.; Coutinho,Luiz L.
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 difficult due to genotypic similarity. Even so, the most likely mother could be identified unambiguously among offspring in most of the clutches studied. Two non-parental females displayed maternal behavior which would have misled managers in assigning maternity based on behavior alone. This set of variable loci demonstrates the utility of parentage testing in captive propagation programs.

Cranial sexual discrimination in hatchling broad-snouted caiman (Caiman latirostris)
Provedor de dados: 76
Autores: Piña,Carlos; Larriera,Alejandro; Siroski,Pablo; Verdade,Luciano M.
Broad-snouted caiman (Caiman latirostris) hatchlings present a consistent sexual dimorphism in their cranium shape and size. Male hatchlings have smaller crania than females. Using multivariate statistical analyses it is possible to discriminate sex in broad-snouted caiman hatchlings by their cranial shape with a reasonable efficiency. The understanding of sexual dimorphism of crocodilian hatchlings might be possibly improved by experimental approach considering, genetic and phenotypic variables such as incubation temperature and clutch of origin.

BLOOD CELL MORPHOLOGY AND LEUKOCYTE DIFFERENTIAL OF MORELET'S CROCODILE (Crocodylus moreletii) (CROCODYLIDAE)
Provedor de dados: 37
Autores: GUTIÉRREZ-CERVANTES,Adrián; AHUJA-AGUIRRE,Concepción; LÓPEZ-de BUEN,Lorena; VIVEROS-PEREDO,Sergio.
ABSTRACT The objective of the study was to determine the morphological characteristics of peripheral blood cells (erythrocytes, leukocytes, thrombocytes) and the leukocyte differential count (heterophils, eosinophils, basophils, lymphocytes, monocytes, azurophils) of captive Morelet's crocodiles (Crocodylus moreletii) from Veracruz, Mexico. Peripheral blood from 80 apparently healthy farmed crocodiles (39 subadults [19 females, 20 males] and 41 adults [18 females, 23 males]) was examined for morphology through stained blood smears and manual count was used for the leukocyte differential. Blood was collected during the non-breeding (n = 42) and breeding (n = 38) seasons. Blood examination indicated similar morphological characteristics of blood cells in...

Aerobic bacterial microflora of Broad-snouted caiman (Caiman latirostris) oral cavity and cloaca, originating from Parque Zoológico Arruda Câmara, Paraíba, Brazil
Provedor de dados: 58
Autores: Silva,J.S.A.; Mota,R.A.; Pinheiro Júnior,J.W.; Almeida,M.C.S.; Silva,D.R.; Ferreira,D.R.A.; Azevedo,J.C.N.
The objective of this study was to isolate and identify the aerobic bacterial microflora from the oral cavity mucosa and cloaca's samples, collected from Broad-snouted caiman (Caiman latirostris), born and bred in captivity at Parque Zoológico Arruda Câmara, João Pessoa, Paraíba, Brazil. The most common bacteria were Staphylococcus sp. (14.74%), Corynebacterium sp. (13.68%), Escherichia coli (13.68%) and Shigella sp. (11.58%), and the less common were Citrobacter sp. (1.05%), Klebsiella pneumoniae (1.05%) and Salmonella sp. (1.05%).This emphasizes the importance of these microorganisms' participation in infectious processes (sepsis) and injuries caused by crocodilians.
