EO1- BRUCELLOSIS ERRADICATION PROGRAM IN URUGUAY.
Garín Alfredo. Jefe Programa de Errradicación de Brucelosis y Tuberculosis. Ministerio Agricultura y
Pesca, División Sanidad Animal. Montevideo-Uruguay.
In 1926 bovine Brucellosis was diagnosed in tuhis country for the first time.
Since then, different actions have been taken in order to diminish the prevalence of
this disease. We went throug voluntary stages and obligatory ones, in wiche different
tool available were used. In 1998 after a control stage that lasted thirty four years
there started an Erradicacition Program using different procedures, depending on the
type of cattle (milk producers or beef). With this Program development and
surveillance increase, some problems have been detected. Today, the Official
Veterinary Service, independents veterinarians and cattle breeders are devoted to
solving these problems. This work develops the different stages of this Program
dealing with what we consider achievements and errors, as wells. We believe this
analysis to be important contribution to other countries that are also working on this
desease.
EO2- BOVINE BRUCELLOSIS CONTROL PROGRAM IN MÉXICO: PRESENT
SITUATION AND FACTORS THAT LIMITS ITS ADVANCE.
R. Flores-Castro. Dirección de Investigación en Salud Animal y Salud Pública,DGIP/INIFAP. México.
Bovine Brucellosis control in Mexico has been performed since the second
half of the 20 th sentury, however it was until 1995 when the first official regulation was
published, as a NORMA OFICIAL MEXICANA, for the control of the disease.The
official proeradication program describes the authotized diagnostic tests, as well as
the recommendations for the use of vaccines. During several years only strain 19
Vaccines were used, for calfs immunization. Later, the reduced dosis of this vaccine
was included en the program and in the last 8 years RB 51 vaccines are officially
used for the immunization of calf and cattle.
Despite the fact that we have all elements needed for a succesfull program,
the advances are not as expected. From 1965 to 2001, the number of animals tested
for brucellosis diagnostic were 14,351,061; from them 110,223 were identified as
reactors ( 0.77%). In the year 2001, the number of tested animals was 2,372,609,
with 13,975 reactors (0.59%). In contrast, the number of doses of vaccine used every
year is only about one million. Last year, this number was 1,187,000 dosis, however,
some animals are vaccinated two or more times. This means that less than a million
animal are immnized every year, while the cattle population in this country is about
28 millions. Other important limitating factor is the fact that not all the reactors are
eliminated or segregated, thus the bacteria persist in the farms.

Research Institute, Vom Plateau State, Nigeria.
Brucellosis is recognised as an endemic disease in Nigeria, affecting large
population of animals and posing big public health problems. Seroprevalence of
brucellosis has been reported in cattle, sheep, goats pigs, dogs horses, chickens and
