Control of Brucella melitensis infection in a large camel herd in Saudi Arabia using antibiotherapy and vaccination with Rev. 1 vaccine.

The authors describe an attempt to control Brucella melitensis infection in a large camel herd in Saudi Arabia. Sera from the entire herd (2,536) were examined by the Rose Bengal and standard United States of America buffered plate agglutination tests. The overall Brucella seroprevalence was 8%.

Successful therapeutic regimens for treating Brucella melitensis and Brucella abortus infections in cows.

Three therapeutic regimens were evaluated in 121 cows naturally infected with Brucella melitensis or Brucella abortus, using a combination of long-acting oxytetracycline (LA-OTC), streptomycin (ST) and OTC-intramammary infusion (IMI). Cessation of shedding of Brucella in udder secretions and absence of Brucella in selected tissues were considered criteria for successful treatment. Regimen A (tested on 35 cows) consisted of LA-OTC 25 mg/kg administered intramuscularly (i.

Treatment of Brucella melitensis infection in sheep and goats with oxytetracycline combined with streptomycin.

Six treatment regimens using oxytetracycline (OTC) combined with streptomycin (ST) were evaluated for eliminating Brucella melitensis from 480 naturally-infected sheep and goats. Cessation of shedding Brucella from udder secretions and absence of Brucella in selected tissues at autopsy were considered criteria for successful treatment. Four regimens were equally effective in eliminating Brucella in the treated groups of sheep and goats regardless of the source of antibiotics used.

Serological and bacteriological study of brucellosis in camels in central Saudi Arabia.

Sera from 2,630 apparently normal adult camels (Camelus dromedarius) raised in central Saudi Arabia (Riyadh and Al-Kharj cities) were examined serologically by the Rose Bengal and standard United States of America Brucella plate agglutination tests. The overall seroprevalence of brucellosis in the restricted populations of tested camels was 8%. The seroprevalence of brucellosis among camels raised in small numbers in the backyards of 24 houses in Riyadh and those intensively raised on one large camel farm near Al-Kharj were 4.
