RESUMO

BACKGROUND OBJECTIVES: Vector borne haemoprotozoan diseases comprise diverse group of single celled organism transmitted by haematophagus invertebrates. The current study was aimed at identification of major haemoprotozoan (Babesia, Theileria and Trypanosoma) in dromedary camel of North Gujarat region using microscopy and Polymerase Chain Reaction (PCR). METHODS: A total of 234 blood samples were screened by the microscopic and molecular detection assays. Molecular prevalence studies of Theileria, Trypanosoma spp and Babesia was undertaken using 18s ribosomal DNA, RoTat 1.2 and SS rRNA gene respectively. The data relating to microscopic and molecular prevalence along with associated risk factors were analysed by statistical methods. RESULTS: The overall prevalence of hamoprotozoan disease based on microscopic and molecular investigation was 23.50%. The sensitivity and specificity (95% Confidence Interval) of PCR assay was 100% in comparison to microscopy (45.45% and 100%). The kappa coefficient between PCR and microscopy indicated good level of agreement with a value of 0.704 and SE of 0.159. INTERPRETATION CONCLUSION: Despite holding much significance to the animal sector, little work has been undertaken in regional part of India regarding camel parasites. The present paper offers the first preliminary research data investigating haemoprotozoan disease using parasitological and molecular methods in camels in the region.

RESUMO

Around 60% dairy animals developed moderate to severe hepatic lipidosis at the time of parturition or during early lactation stage. Most of clinician suspect the hepatic lipidosis during above time window only. However, negative energy balance or feeding of high concentrate diet can lead to hepatic lipidosis at any phase of life. The aim of the present study was to evaluate the potential for diagnosis of hepatic lipidosis by means of hemato-biochemical parameters and ultrasonography of the liver at any stage of life. Here, ultrasonographic back fat thickness measurement was correlated with ultrasonographic features of hepatic lipidosis. A total 60 buffaloes were included under the study and sampled for hematological and biochemical parameters. Hematological parameters did not exhibit any significant difference between healthy and hepatic lipidosis-affected buffaloes. Biochemical parameters like beta hydroxy butyric acid, non esterified fatty acid, aspartate amino transferase, gamma glutamyl transferase and alkaline phosphatase revealed a significant increase, while triglyceride, cholesterol, and glucose declined significantly in hepatic lipidosis-affected buffaloes. Total protein, albumin, and total bilirubin levels did not exhibit any significant difference. Based on ultrasonographic findings, the hepatic lipidosis-affected buffaloes were further sub divided into mild, moderate, and severe groups. Portal vein diameter and depth of portal vein were also estimated in current study. Ultrasonographic examination could diagnose 53.33% hepatic lipidosis cases in buffaloes. Among it, 37.50% buffalo had mild hepatic lipidosis, 33.33% had moderate hepatic lipidosis, and 29.16% had severe hepatic lipidosis. Depth of portal vein significantly increased in hepatic lipidosis cases. However, portal vein diameter exhibited a non-significant difference in mild, moderate, and severe groups of hepatic lipidosis. Back fat thickness also revealed a non-significant difference in mild, moderate, and severe hepatic lipidosis. Above study indicate that B mode ultrasonography of the liver can be employed to differentiate various grades of hepatic lipidosis in buffaloes. Biochemical parameters like NEFA, BHBA, AST, GGT, ALP, TG, cholesterol, and glucose can be helpful to screen the hepatic lipidosis at farm level.
