Specimens of prostatic fluid were collected by ejaculation from 104 dogs after collection of a specimen of urethral contents and after collection of a urine specimen by antepubic cystocentesis. For purposes of data analysis, results of bacterial culture of the specimens were grouped according to individual colony counts in each specimen group (ie, urine, urethra, prostatic fluid). For purposes of this study, prostatic infection was defined as greater than or equal to 2 log10 of one or more bacterial species in prostatic fluid over the number of colonies of the same species in the paired urethral specimens.
在收集尿道内容物标本和经耻骨前膀胱穿刺采集尿液标本后，通过射精从104只犬收集前列腺液标本。为了进行数据分析，将标本的细菌培养结果根据每个标本组（即尿液、尿道、前列腺液）中的单个菌落计数进行分组。在本研究中，前列腺感染的定义为前列腺液中一种或多种细菌的菌落数比配对尿道标本中相同细菌的菌落数多2个对数10或更多。
