background and objective: brucellosis is a zoonotic disease of worldwide distribution and has great economic importance. despite its control in many countries, it remains endemic in iran. brucellosis was investigated in many high risk occupational groups; however, few studies on the prevalence of brucellosis among blood donors are available. to determine the seroprevalence of brucellosis antibo...

Brucellosis is a contagious zoonosis caused by Brucella Infection transmitted wools, hairs, milk, butter, cheese and meats of infected animals. Skin, conjuctiva respiratory mucosa also constitutes entry routes for bacteria other than digestive system. Wright agglutination generally used diagnosis.In this study. agglutinins were searched in the sera 100 butchers method. The results compared with...

0.1% Protamine sulphate in normal (0.85% w/v) saline has been used as a diluent in Brucella serology instead of saline as such. The use of protamine sulphate in this concentration has obviated the need for performing the modified Coombs test to detect non-agglutinating Brucella antibodies. This method has been used in the Microbiological Diagnostic Unit of the University of Melbourne in the rou...

It was shown by Wiener (1944) that some human a,nti-Rh sera contained incomplete antibodies which combined with but did not agglutinate the corresponding red cells. They appeared to be more avid than agglutinating antibodies, so that, if the two kinds of antibody co-existed in the same serum, the incomplete or blocking antibody might account for failure of agglutination or for a zone of inhibit...

The microagglutination technique without centrifugation was more effective than centrifugation of the standard tube test for increasing Brucella agglutinin titers of specimens with a titer greater than or equal to 160 but was less effective than centrifugation of the standard tube test for specimens with a titer less than 160.

In a herd of cattle in which several cows are infected with Brucella abortus, it has been observed for many years that seldom, if ever, do all adult cows become infected. Very often a considerable percentage of animals in such a herd even fail to show by diagnostic tests indications of having been exposed to infection. It has been assumed that they were resistant to infection, this resistance b...

THE clinical diagnosis of undulant fever or brucellosis is frequently a matter of very great difficulty. This difficulty is made apparent by a short review of the opinions of various authors as they set them out in current textbooks of medicine. Thus, G. M. Low and N. H. Fairly in their contribution to Price's Textbook of Medicine (6th Edition) state that the differential diagnosis of undulant ...
