Evaluation of cellular immunity in bovine brucella seropositive animals has been preformed , using one invitro test , the leucocytes migration test " LMIT " and one invivo test , the skin reaction by using prepared brucellin form Brucella abortus strain RR51 .All these tests showed significant reactions and proved to be reliable tests for proper appreciation of cellular immunity in bovine bruce...

brandenburg, stanley, and anatum, showed no reduction in viable count compared with MacConkey's medium. The growth of salmonellae was somewhat slower than on ordinary MacConkey agar but most produced colonies of 1 mm diameter at 22 hours and only five required incubation for 36 hours. Six of the 41 Salmonella species tested failed to grow (typhi, paratyphi A and C, cholerasuis, gallinarum and p...

Allergic examination using PPD-tuberculins is the main method of life-time tuberculosis diagnostics in farm animals and poultry. However, it known about a decrease diagnostic value allergic reactions after irradiation animals, occurrence non-specific, pseudo-allergic reactions. One reasons for manifestation non-specific may be autosensitisation (autoallergisation) body by breakdown products per...

brucellosis is a widespread zoonotic disease causing considerable economic and public health problems. despite animal vaccination, brucellosis remains endemic in some areas such as iran, especially in the western iranian province of hamadan. we sought to detect some of the most common virulence-associated genes in brucella isolated from human blood cultures to determine the prevalence of some v...

The only known means of effectively separating populations of X and Y bearing sperms is the Beltsville sexing technology. The technology implies that each individual sperm is interrogated for DNA content, measuring the intensity of the fluorescence after staining the spermatozoa with Hoechst 33342. Because there are no data regarding the effect of the staining on stallion sperm, ejaculates were...
