Poster Session
Brucellosis is one of the most important infectious and zoonotic diseases in
Iran. Genus of Brucella has seven species including: B. melitensis, B. abortus, B.
suis, B. ovis, B. canis, B. neotomae and B. maris which two of them (B. melitensis, B.
abortus) are very dangerous in humans and animals in Iran. Brucellosis commonly is
transmitted to human by animals and animals’ products. The diagnosis of the disease
is based on serological and bacteriological methods in Iran. The purpose of this study
was to detect the incidence of brucellosis in Yazd province.
This study was carried out in the Abarkouh city of Yazd province of Iran. The
populations of human, cattle and sheep of Abarkouh city were estimated about
50000, 8000 and 300000 respectively. Samples: One thousand and two hundred
sera samples were taken from sheep (800 samples), goats (200 samples) and
human (200 samples) in autumn and winter. Human sera samples were collected
from central medical laboratory of Abarkouh city and sera samples of sheep and
goats were collected from the farms around of the Abarkouh city. Tests: The samples
were tested by using Slide (Rose Bengal) and tube (Wright) agglutination tests.
The results showed seropositive rate in goats, sheep and human were %2/5,
%1 and %1/37 respectively. It is generally accepted that brucellosis induces both
humoral and cellular immunity responses. The humoral response to brucella infection
in human and animals has been subjects of many studies in many countries (1 and
2). Coming to conclusion, the results of our study have revealed the incidence rate of
brucellosis in goat is more than human and sheep in central part of Iran.

112 animals belonging to sixteen sheep flocks suspicious (FCT positive) of
Brucella melitensis infection were sacrificed and ten tissue samples taken from each
one. Samples were analyzed by microbiology cultures in order to describe different
microbial distribution pattern in sheep bodies and relationships with epidemiological
and serological status of the flock. Special attention was made in very low (less than
1% serological positive reactors) and low (less than 5% positive reactors) prevalence
flocks. The results suggest that mammary gland and lymph node biopsy will be the
best options to confirm brucellosis infection in all of the epidemiological situations
described and that very low positive flocks needs additional studies to asses their
infection status.
