Among 292 heterosexual men with gonorrhoea seen during one year, 59 (20%), had a co-existing chlamydial infection. Of the men infected with a serogroup WI strain 30% had a chlamydial infection compared with 16% of those infected with a serogroup W II/III strain (p less than 0.01). Heterosexual men infected with WI strains had less objective symptoms as judged by the number of leucocytes per high power field and by discharge, than men infected with W II/III strains (p less than 0.05 and p less than 0.01, respectively).
在一年中接诊的292例患淋病的异性恋男性中，59例（20%）同时感染了衣原体。在感染WI血清群菌株的男性中，30%感染了衣原体，而感染W II/III血清群菌株的男性中这一比例为16%（p<0.01）。根据每高倍视野白细胞数量和分泌物判断，感染WI菌株的异性恋男性比感染W II/III菌株的男性客观症状更少（分别为p<0.05和p<0.01）。
