background: the occurrence of giardia duodenalis in cats is of potential significance from both clinical and public health perspectives. the object of this study was antigenic detection of g. duo­denalis in house­hold cats of ahvaz district, south-west of iran. methods: the prevalence of g. duodenalis was determined in fecal samples by two techniques: centrifuga­tion-flotation and a commercial ...

1. The human thymus-brain antigen, which corresponds to the murine (mouse or rat) Thy1 antigen complex, was isolated from brain after solubilization in deoxycholate by gel-permeation chromatography, wheat-germ-lectin affinity chromatography and ionexchange chromatography. 2. The isolated antigen is a glycoprotein displaying an apparent molecular weight of 26000-29000 in sodium dodecyl sulphate/...

In the last decades researchers had focused on developing a vaccine against tick based on protective antigen. Recombinant vaccines based on concealed antigen from Boophilus microplus have been developed in Australia and Cuba by the name of TICKGARD and GAVAC (De La Fuente and Kocan, 2006). Further studies on this antigen have shown some extent of protection against other species (De Vos et al.,...

ported criteria of S/LC -cTnI 6.7 or S/LC -cTnT 5.3 (1, 2 ). Taken together, 55 (15.9%) of the 345 samples were positive for autoantibodies to cardiac troponin I or T isoforms. In these positive samples, 10.9% (6 of 55) were positive for both autoantibodies. The odds of being positive for both autoantibodies increased in the presence of either species; in samples positive for autoantibodies to ...
