A systemic study on the pathogenesis of experimentally induced
Salmonella typhimurium infection was carried out in calves. Sixteen normal,
colostrum-fed, friesian calves, ranging in age from 3 to 6 weeks were used. The
calves were divided into two equal groups. Group I calves were inoculated
orally with 1.5 x 1011 CFU of Salmonella typhimurium and group II calves
served as control.
Using an indirect fluorescent antibody technique, it was found that
Salmonella typhimurium has an apparent predilection for the small intestine
particularly jejunum and ileum. The results of this study suggest that this
technique can be considered as a rapid reliable technique for diagnosis of
salmonellosis in endemic outbreaks.

Morphological variation in helminthes parasites is a well- established phenomenon and may have many
sources and important taxonomic implications. The morphological differences between the two isolates of
Echinococcus granulosus were the dimensions of worm total length , number of the developing segment ,
testes distribution , details of the cirrus sac and position of genital pore .The results of present study indicate
that there is a form of the parasite is adapted to donkey and other in camel have some differences in
morphological also biological features not tackled in the present work .Genetic study is required for strain
detection for clarification of the situation in a country .

The objective of this study was to determine the effect of adding aspirin to the diet on some
biochemical parameters such as blood serum glucose , cholesterol , uric acid , total protein ,
phosphorus and calcium concentrations of broilers reared in high density (15 birds / m ) . A 90 chicks 7
days old were distributed into two treatments (45 chicks per treatment ) , T1 chicks fed a diet without
aspirin (control) , chicks in T2 fed a diet supplemented with 0.2 % aspirin (2 mg aspirin / kg feed) .
Each treatment subdivided into three replicates and each replicate reared in 1 X 1 m pen . The data
obtained revealed the following:
Blood serum glucose concentration were 189 mg /100 ml , cholesterol concentration were 207

This study was conducted to compare the effect of adding organic chromium (Biochrome) and
organic acids (Galli acids) for reducing experimentally infected broiler chicks by Salmonella
typhimurium . A total of 400 one day old broiler chicks were divided into four dietary groups which
were: un-treated negative control (T1) , 044 ppb organic chromium / kg feed (T2) , 4.0 of organic acids
/ kg feed (T3) and positive control (T4) . After one day of feeding T2 ,T3 and T4 chicks were oral
experimentally infected by S. typhimurium. Results have shown :
Mortality of positive control broiler chicks were 70 % , added organic chromium and organic acids
reduced chicks mortality tto 10 % in each , also the results revealed that th
