Australia Antigen in Urine and Feces

Abstract

tients after symptoms had subsided.3 Thus, an antigen was found in feces which seemed to be associated with acute hepatitis and which was detected by anti-SH antisera. A cru¬ cial question is whether the detected fecal antigen indicates infectivity of feces analogous to SH-antigen posi¬ tive sera. Identification of fecal anti¬ gen with SH-antigen as found in sera would clearly be of help. The results obtained by the Ouchterlony method showed that fecal antigen was identi¬ cal or at least shared common anti¬ genic sites with SH-antigen from se¬ rum. Nevertheless, slight differences in specificities of antigen in feces and serum or of the antisera used might decisively influence the results. To gain further information on this

Lack of infectivity of HBV in feces from patients with chronic hepatitis B virus infection, and infection using chimeric mice

“…Regarding feces, the results of several investigations are conflicting [ 13 , 19 – 33 ], and no experimental transmission of HBV using an animal model had been performed. In some studies, HBsAg was detectable in the feces of patients with an acute and chronic infection [ 19 , 21 , 23 , 24 ]. In contrast, other studies failed to identify HBsAg in the feces [ 25 , 30 , 33 ].…”

“…A transmissão é favorecida pela alta estabilidade e virulência do HBV, associada com a elevada concentração no sangue de pessoas infectadas (LAVANCHY, 2004;HUTSE et al, 2005;TENGAN;ARAUJO, 2006 (ALTER, 2003;FERREIRA et al, 2006;SHAPATAVA et al, 2006;AREIAS, 1996;CARNEIRO, 1997; (HOLLINGER, 1996;MARGOLIS et al, 1997), tais como saliva (DAVISON et al, 1987;JENISON et al, 1987), sêmen (ZHANG et al, 1994), secreção vaginal (DARANI;GERBER, 1974;YUE et al, 2004), urina (TRIPATZIS, 1972;IRWIN et al,1975;HOURANI et al, 1978), colostro ou leite materno (YANG et al, 1999;ZENG et al, 2006;LU et al, 2008), fezes (VILLAREJOS et al, 1974;DAVISON et al, 1987), dentre outros (LEE et al, 1978;ZHANG et al, 2004).
