A STUDY ON SOME ZOONOSES IN DJIBOUTI REPU BLIC .1. RUMINANTS FROM DJIBOUTI SLAUGHTERHOUSE

A prevalence survey on 1 500 bovine carcasses in Djibouti slaughter-ho use did not reveal any macroscopic lesion of tuberculosis. Thirteen an imals (0.86 %) showed hydatic cysts and 17 cases of muscular cysticerc osis were detected (1.13 %). From 2 500 small ruminants carcasses, 23 hydatic (0.92 %) and 2 Cysticercus ovis cases were detected. Four hund red and ninety nine sera sampled from cattle in the area revealed prev alences of 4.0 % for brucellosis, 1.0 % for chlamydiosis and for Q-fev er, 4.45 % for hydatidosis, and 2.8 % for toxoplasmosis. No positive r eactions were detected for Rift Valley Fever or Crimean-Congo Hemorrha gic Fever. The same serologic tests were applied to 1 081 sera from sm all ruminants and revealed a prevalence of 2.6 % for brucellosis (shee p: 1.0 %, goats : 4.0 %), 0.1 % for chlamydiosis (respectively 0.2 % a nd 0 %), 7.0 % for Q-fever (resp. 3.5 % and 10.6 %), 0.5 % for Rift Va lley Fever (0.4 % and 0.7 %) and 0.8 % for Crimean-Congo Hemorrhagic F ever (0.8 % and 0.9 %). Hydatidosis was serologically detected in 12.0 % of sheep and 9.6 % of goats, as well as toxoplasmosis (respectively 9.8 % and 6.4 %).
