“…Various organisms are known, or have been thought, to be implicated in NGU infections, namely Chlamydia trachomatis (Darougar et al, 1971 ; Bowie et al, 1977 a ; Richmond & Clarke, 1977;Taylor-Robinson & Thomas, 1980), Ureaplasma urealyticum (Taylor-Robinson, 1977 ;Taylor-Robinson et al, 1977Taylor-Robinson & McCormack, 1979;Taylor-Robinson & Csonka, 198 I), Clostridium dzfficile (Hafiz et al, 1975), Corynebacterium species (Furness et al, 197 1, 1977), and Staphylococcus saprophyticus (Hovelius et al, 1979). Other organisms, namely Gardnerella vaginalis (Lapage, 196 1 ;Jones et al, 1982 ;Kinghorn et al, 1982 ;Tabaqchali et al, 1983) and anaerobic curved rods (Holst et al, 1981 ;Sprott et al, 1983) are currently regarded as potential agents of NSV. Although various investigators have searched for anaerobes in lower genital-tract infections in men, evidence that they are associated with disease has not been substantiated (Bowie et al, 19773;Hallen et al, 1977).…”
