Cold agglutinins (CA) were evaluated prospectively in patients with various mononucleosis syndromes and in a large control group. Cold agglutinins with anti-i specificity were seen mainly in heterophil-positive or -negative Epstein-Barr virus (EBV)-induced infectious mononucleosis (31.8% of cases). Unclassified CA with equal reactivity against cord and adult erythrocytes were seen in 56 of 150 ...

The present study aimed to determine haemato-biochemical constituents and corticosterone level of synthetic coloured broiler male line affected with heat stress. We hypothesized that haemoglobin (Hb), Packed cell volume (PCV), total erythrocyte count (TEC), lymphocyte eosinophil values were significantly higher in control whereas leucocyte (TLC), heterophil basophil stress group. Additionally, ...

Heterophils are the predominate granulated leukocyte in the acute inflammatory response in gallinaceous birds. Heterophils are highly phagocytic and are capable of a broad spectrum of antimicrobial activity. They accumulate in inflamed tissue, causing tissue damage and forming heterophil granulomas that are morphologically similar to inflammatory lesions in reptiles. The avian heterophil lacks ...

The EBV IgG titres in acute and convalescent specimens from 97 cases of infectious mononucleosis were compared with titres from acute and convalescent sera from 96 students with illnesses resembling infectious mononucleosis but without heterophil antibody, EB IgM or EB IgG seroconversion; and also with titres from 91 healthy students known to have had EB IgG antibody for at least six months. Th...

Serial passage of Salmonella enteritidis (SE) yields heterophil-adapted SE (HASE) strains that have resulted in decreased shedding of SE in feces and reduced egg contamination. Additionally, increasing the number of heterophil passages further reduced the number and frequency of fecal shedding. To evaluate SE and heterophil interaction, nine SE strains were fluorescein isothiocyanate-labeled wh...

The immune system of neonatal chicks is functionally immature during the first week of life. Researchers have previously demonstrated that the avian humoral response can be increased with probiotics. Although the humoral response provides the chick with an effective mechanism to combat pathogens, sufficient antibody titers are not attained until 7 to 10 d postinfection. However, the innate immu...

We hypothesized that heterophil antibodies reactive with animal proteins used in blot preparation caused nonspecific staining (NSS) on HIV Western blot (WB) studies, causing indeterminate results. We analyzed samples showing NSS on HIV WB using a multiplexed immunoassay to simultaneously measure IgG antibodies to animal IgG (bovine, goat, sheep, mouse) and bovine serum albumin. Heterophil antib...

Aengwanich, W. and Chinrasri, O. Effect of dexamethasone on differential white blood cell counts and heterophil / lymphocyte ratio in Japanese quails (Coturnix coturnix japonica) Songklanakarin J. Sci. Technol., 2003, 25(2) : 183-189 Laying Japanese quails (n = 60), 30 weeks of age reared at the experimental laboratory unit of the Faculty of Technology, Maha Sarakham University, Maha Sarakham p...

Staphylococcal tenosynovitis and osteomyelitis are world-wide problems of broilers and broiler breeders. Avian heterophils are analogous to mammalian neutrophils but the granules appear to be Afferent. The main objective of the study was to compare heterophil chemotaxis using heterophil obtained from healthy and staphylococcal infected chickens. Commercial broiler chickens were obtained to serv...

Over several years sera were collected from 14 heterophil-positive students or patients who did not fulfill minimal hematologic criteria for infectious mononucleosis (I.M.) The specificity of these heterophil reactions for I.M. was investigated by determining antibodies to Epstein-Barr virus-determined antigens, i.e., to viral capsid antigens (VCA), early antigens (EA), and EBV-associated nucle...
