East Mediterr Health J. Jul-Sep 2001;7(4-5):791-8.

Abstract

All 137 brucellosis cases occurring in Tabuk Province, Saudi Arabia in 1997 were studied retrospectively. Brucella agglutination titre of > or = 1/80, or rising titre plus history of typical signs and symptoms were considered evidence of infection. The incidence rate was 34/100,000, mean age 33.8 +/- 13.9 years (range: 3-72 years) and male:female ratio 1.8:1. There were 63.5% of cases rurally resident, 58.4% kept animals at home or elsewhere, 27.0% worked with animals and/or on farms, and 88.3% reported a history of raw milk ingestion. The most common infecting agents were Brucella melitensis, B. abortus and B. suis. Splenomegaly and hepatomegaly were detected in 25.5% and 22.6% of cases respectively.
