Enzyme-Linked Immunosorbent Assay Using Monoclonal Antibodies for Direct Serotyping of Enteric Adenoviruses in Feces

We were prepared three monoclonal antibodies in which the monoclone 12D was type specific for Adenovirus 40 (Ad40), 1F was type specific for Ad41 and 15D was group specific for Ads. For identification of enteric adenoviruses (EAd) in stool specimens, enzyme-linked immunosorbent assay (ELISA) test using monoclonal antibodies was developed. Results of identification by the ELISA tests using monoclonal antibodies to EAd on 15 fecal samples in which Ad particles were found by electron microscopy showed complete coincidence to those of Sma 1 restriction endonuclease cleavage. From these results, the ELISA tests employing EAds type specific monoclonal antibodies proved to be specific and this was a rapid technique for laboratory diagnosis of EAd in fecal specimens of viral gastroenteritis. Fifty-eight fecal samples with Ad particles positive by EM were serotyped by the ELISA using monoclonal antibodies. Eleven fecal samples were identified as Ad40, 25 as Ad41, 1 as double infection with Ad40 and Ad41, and 4 as non-EAd. These results indicated that Ad41 was more dominant than Ad40 during April, 1986 to January, 1989 in Matsuyama city.
