The manner in which a single injection of S. typhosa endotoxin effects the primary hemolysin response to sheep erythrocytes in the mouse has been shown to depend on the dosage, route, and time of administration of the endotoxin, as well as on the route employed for the injection of antigen. The normal production of antibody, following an intravenous or an intraperitoneal injection of red blood ...

SYNOPSIS Sheep red cells, sensitized with a genus-specific leptospiral substance extracted from a water leptospira, were preserved by freeze drying. The serological reactivity of the preparation was tested against a total of 41 sera from proven cases of human leptospirosis and 27 from proven cases of animal leptospirosis. The sensitized, freeze-dried red cells appeared to be a sensitive reagent...

A woman with a T cell lymphoproliferative malignacy and heterozhgosity at the X chromosome-linked locus for glucose-6-phosphate dehydrogenase (G-6PD) isoenzymes was studied to find the clonal origin of her circulating neoplastic T cells. The red blood cells, polymorphonuclear cells, whole mononuclear cells, and T cell-depleted mononuclear cells contained both A and B isoenzymes of G-6-PD. In co...

b ackground : anaplasma ovis infections can cause clinical symptoms in acute phase and lead to huge economic losses in flocks. the aim of the present study was to investigate the hematological and par- asitological changes in experimental anaplasmosis in sheep with iranian strain of a. ovis . m ethod: five male sheep without any blood parasite infection were selected. one hundred ml hepa-rinize...

A cross-sectional survey was conducted at Constantine’s slaughterhouse in Northeast Algeria between February 2018 and 2019. Livers lungs of 2574 sheep 1036 cattle were examined for the presence lesions. The overall prevalence lung lesions 33% 32% cattle, respectively. most frequent lesion red hepatization (19%) followed by pleurisy (12%). In cystic echinococcosis (24%), (7%) emphysema (5%). Lun...

Young cells produced in LK sheep during rapid hematopoiesis after massive hemorrhage contain more K than the cells which are normally released into the circulation. The K content in these new cells falls to that characteristic of mature LK cells after a few days in the circulation. K transport properties in young and old cells before and after massive bleeding were studied. Young and old cells ...

Objective: The immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. Materials and Method: The essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. The essential oils were tested for hypersensitivity and hemagglutination reaction...

A 42-day study was conducted to evaluate the influence of full-fat flaxseed (FS) and canola seed (CS) on broiler performance, fatty acid (FA) profile of meat, serum lipid content and antibody response to sheep red blood cells antigen (SRBC). A total of 324 one-day-old chicks were attributed to 6 experimental groups. C: control (soybean-corn); CS1:7.5% CS; CS2:15% CS; CS-FS:10% FS + 10% CS; FS1:...
