Abstract
The present study was carried out to evaluate the percent of MAP infection among imported cattle from Sudan to Egypt during the period of investigation (13 months) in the quarantine period in Abu-Simbel Veterinary Quarantine at the South border of Egypt. A total number of 1500 imported cattle were inspected from May, 2015 till May, 2016, clinically examined and sampled during different months of the year, different age, and with male in relation to sex for epidemiological studies using fecal smear and ELISA techniques for diagnosis of MAP infection.
The clinical signs of the examined cattle infected by MAP can be summarized as follow:
Out of 1500 examined cattle, 200 (13.34 %) cases showed clinical abnormalities suggesting its infection with MAP and the remained cases (86.66%) appeared to be clinically healthy. The prevalence of MAP infection using fecal smear technique was 16.0% among the clinically suspected cases whereas; the prevalence of MAP infection using ELISA was reached 4.35% among clinically suspected cattle.
The prevalence of MAP infection according to presence of acid fast bacilli in their fecal smear is higher in old aged animals (6 years) with percent of 22.5% and the presence of MAP infection according to ELISA procedures is higher in old aged animals (6 years) with percent of 7.5%.
The obtained results indicated that higher percentage of MAP infection by fecal smear than ELISA techniques were observed and discussed. Cattle were positive by fecal smear found to be negative by ELISA technique, as ELISA technique is sensitive and specific for the detection of MAP in the blood of cattle. These indicate that there were high proportion of clinical and carriers of MAP infection among the imported cattle.
The obtained results in the present study indicate the spread of MAP infection among cattle population imported from Sudan. Consequently, it is recommended that good management and hygienic precautions should be carried out immediately to minimize the entrance of infectious diseases from Sudan to Egypt, establish a modern laboratory unit containing ELISA in Abu-Simbel Veterinary Quarantine for cattle diseases to reveal up the infectious diseases among cattle and other animals.
