to detect the presence of infectious bronchitis virus (ibv) in infected allantoic fluid (af) of spf embryonated eggs rapid hemagglutination (ha) activity after treatment with neuraminidase enzyme was used. twenty ibv suspected materials were inoculated in spf embryonated eggs via chorioallantoic cavity. harvested afs were treated with neuraminidase enzyme and the presence of ibv was detected by...

in a comparative study, 460 serum samples were tested for the serological determination of human immunodeficiency vrius (hiv) using an elisa kit and a rapid test kit. results indicated that the rapid test is reliable for screening unkonwn samples when there is no special equipment for screening with immunoblotting and/or elisa.

The rapid corticotropin test with synthetic corticotropin ( 1-24 peptide) was studied. A single intravenous injection of the corticotropin was performed in 26 human subjects. The increment of plasma 11-0HCS concentration by the administration was less than that of NH-corticotropin dripping infusion or synthetic corticotropin intramuscular injection. Intramuscular rapid corticotropin test was co...

A rapid and sensitive urease test for mycobacteria utilizing a cumulative radiometric technique is described. Definitive results were obtained within a 30-min incubation period. The procedure is simple and economical. Technical time involved is no greater than in conventional procedures.

the objective of the present study was to determine the grades of nonspecific bacterial infection of genitalia of repeat breeding cattle by a simple and rapid test under field condition. for this purpose, a total of 100 crossbred jersey cows comprising of 80 repeat breeding animals presented for treatment and 20 normal cyclic (control group) animals presented for artificial insemination at thei...

A rapid, miniaturized, urea broth test useful for detecting urease activity of yeasts was compared to Christensen urea agar. All urease-producing yeasts tested were positive on both media; however, 60% were reactive in the urea R broth within 30 min, and the remainder were reactive within 4 h. This urea multiwell test may be useful as a rapid screening method for detecting urease-producing yeas...
