Abstract
A survey was carried out over a period between 1994 -1995
determine the total numbers of condemned lungs of different animals
slaughtered at gharbia governorate abattoirs during various seasones. in
addition, the different causes of such condemnations were recorded.
during this period 1556 cows, 12623 buffaloes, 39602 bulls, 24659
buffaloes calves, 646 camels, 23372 sheep and 1314 goats were routinelly
inspected at gharbia abattoirs. the obtained results of the survey revealed
that 1619 lungs of different animals were condemned. this figures
constitutes about 1.59% from the total animals slaughtered in the gharbia
abattoirs. the examined lungs of most slaughtered animals were firstly
condemned as a result of tuberculous lesions, hydatid cysts and
pneumonia. furthennore, the perceatages of condemend lungs of such
.baima’s were greatly varied according to the season of slaughtering of
different animals. from 56%, 4% and 24% of examined cattle lung abscesses and 32%, 8% and 16% of examined camel lung abscesses, respectively. however, mixed infections were detected in 16% and 44% of the examined cattle and camel lungs affected with abscesses, respectively.
enterobacter, micrococcus, alcaligenes, citrobacter, klebsiella and
proteus species were isolated from the examined cattle lungs affected with
pneumonia in percentages of 76%, 64%, 48%, 40%, 28% and 16%,
respectively. moreover, the results of the laboratory diagnosis of suspected lung cases of tuberculosis indicated that out of25 suspected cases, 18 cases
(72%) were diagnosed as tuberculous lesions, while 7 cases (28%) were
negative (false judgment at abattoir). accordingly, the lungs may be
condemned •due to tuberculous lesions but, accurately, they were free from
such tuberculosis lesions. the public health sillficance of the isolated microorganisms and sbme reconunendations . .. ize such condemnations of different carcasses in various ar.e were discussed.
