Seroclinical diagnosis of Anaplasma marginale bacteria in carrier Arabian one-humped camels

Abstract EN

Anaplasmosis is a tick-borne disease of ruminants and wild animals that caused by an intra erythrocytic bacterium, Anaplasma marginale.

Under natural conditions, camels become infected in areas where the disease is endemic.

Camels that survive from acute infection become carriers because of the capability of these bacteria to deception the immune system using antigenic variations.

Although, several serological methods were concerned for Anaplasma marginale IgG antibodies detection, but the competitive indirect ELISA test was more sensitivity and specificity.

The present study was conducted at Al- Najaf and Wasit provinces on 120 camels, selected randomly from both sexes and divided into two aged groups.

The total sero positivity prevalence was (10.83%); and depending on provincial basis was (8.57%) in Al-Najaf and (14%) in Wasit provinces.

Clinically, the sero positive prevalence two age groups (<5 and >5 years old) had (6.67%) and (15%), respectively.

No significant differences (P<0.005) were encountered in sero positive camels in related to sex and vital signs (temperature, respiratory and heart rates), emaciation and paleness of the mucous membrane, while the rough hair coat and presence of ticks encountered a significant difference (P< 0.05).
