“…These values add to the growing literature of hematologic and biochemical baseline and reference ranges reported for crocodilian species. 1,2,12,13,18,23,26,33,34,10,11 Given the high degree of variation in chemistry profile values among reptiles, reference intervals for each species are an important priority.…”

We report hematology and biochemistry reference intervals (RI) for the critically endangered Cuban crocodile (Crocodylus rhombifer). In November 2019, we sampled 43 adult crocodiles (6 male, 37 female) under human care at the Zapata Swamp Crocodile Farm in Matanzas, Cuba. These crocodiles are part of a breeding program for the species registered by the Convention on International Trade in Endangered Species (CITES). Visual health evaluations were performed immediately after manual restraint, and blood was collected from the postoccipital sinus. We performed packed cell volume (PCV), total solids (TS), complete blood counts (CBC), and biochemistry profiles for each crocodile on the day of sampling. Mean PCV (n ¼ 42) was 21.1 6 5.0% and TS (n ¼ 42) 7.3 6 1.2 mg/dl, respectively. Absolute white blood cell (WBC) (n ¼ 40) was 9.6 6 5.7 3 10 9 /L. Similar to other crocodilian species, the dominant leukocyte was lymphocytes (70.7 6 10.4%), followed by heterophils (18.7 6 9.7%). Two of the crocodiles had a high heterophil:lymphocyte ratio (0.87 and 0.74), although on visual exam they were both considered healthy. The range of creatine kinase was 41-1,482 U/L, and the higher values may be a reflection of muscle exertion at time of handling. Limitations to the study included skewed sex ratios and high lipemia and hemolysis in most samples collected. These are the first reference intervals reported for this species, including the first descriptions of WBC morphology. These data are valuable for the management of animals at the Zapata Swamp Crocodile Farm, for comparison with free-living Cuban crocodiles in Cuba, and for comparison with those managed under human care outside of Cuba.

“…El humano la adquiere debido al contacto directo de la bacteria con superficies expuestas de su piel, así como por la ingestión de productos contaminados con ella, principalmente carnes con un proceso de control higiénico poco efectivo durante el faenado (3). En Colombia, la zoocría de caimanes se da en alrededor de 47 establecimientos, cuyos objetivos principales son: la producción de carne y pieles, así como el repoblamiento en zonas en donde debido a la acción humana su número ha disminuido en el ecosistema (4).…”

Objetivo. Determinar la presencia de Salmonella spp y el PRA en aislamientos de hisopados cloacales y musculares en especímenes de Caiman crocodilus fuscus y Crocodylus acutus en cautiverio en Colombia. Materiales y métodos. Se realizó un muestreo de tipo transversal y descriptivo con un diseño no probabilístico por conveniencia una única vez, durante el mes de febrero de 2021. Se incluyeron 150 animales de Caiman crocodilus fuscus y Crocodylus acutus, con una distribución 50/50. Se tomaron muestras cloacales y musculares con hisopos estériles. Estas se sembraron en agar MacConkey, posteriormente en agar SS. Luego, se reconfirmaron las muestras positivas en agar TSI. Se realizó la serotipifación con antisueros monovalentes y polivalentes específicos. Se realizó la prueba de difusión en agar Mueller-Hinton. Resultados. No existió crecimiento de colonias en ninguna muestra muscular. La presencia de la bacteria en muestras cloacales de Caiman crocodilus fuscus fue del 36% y para Crocodylus acutus de 50.6%, los dos serotipos con mayor porcentaje de detección en ambos grupos fueron el serogrupo C1 y el serogrupo polivalente B. Ocho colonias fueron resistentes a tetraciclina, mientras que otras colonias tuvieron una resistencia intermedia a ampicilina, cefoxitin, sulfatrimetropim y tetraciclina. Conclusiones. Este es el primer reporte relacionado con la detección de Salmonella spp. en canales de caimanes en el país, sin encontrar presencia del agente en ninguna muestra evaluada, sin embargo, se recalca la importancia de seguir su monitoreo para garantizar productos inocuos.

The involvement of veterinary medicine in wildlife research has played an important role in understanding the health status of various wildlife species. Health status is a very important aspect of species conservation. However, it requires a widely employed knowledge of veterinary clinical pathology, as a diagnostic tool in diagnosing the various disease conditions of wildlife species. Notwithstanding, a gap exists in the literature about the clinical pathology of the false gharial, due to the lack of normal reference values for hematological and serum biochemical analysis. The present study investigated the normal blood profile of 10 healthy false gharials, from two different zoos, and wildlife conservation centers located in three different states of Peninsular Malaysia. Blood samples were collected from the lateral caudal vein and divided into a vacutainer without anticoagulant for biochemical analysis, and a lithium heparin vacutainer (containing sodium heparin) for hematological studies. The results of the study indicated that the false gharial has a smaller erythrocyte dimension compared to other crocodilian species. At the same time the study revealed that the false gharial in a natural captive pond showed more leukocytes than false gharial kept in zoos, hence, habitat and environmental factors significantly affect hematological values. The biochemistry values also showed differences between the false gharial in different environmental conditions. Total protein, albumin (Alb), globulin (Glob), and Alb: Glob ratio were higher in false gharials kept in wildlife conservation centers than in false gharials kept in zoos. The values obtained in this study provide baseline data of hematological and serum biochemical values of the false gharial for future research and routine clinical diagnosis.
