Neisseria cuniculi was isolated, between March 1987 and March 1989, from 38 cases of respiratory disease in small and large ruminants. In all but five cases N. cuniculi was cultured together with other potential respiratory pathogens. A survey was conducted to assess the prevalence of N. cuniculi in the pharyngeal region of Merino and Awassi purebred sheep, Awassi/East-Friesian and Merino/Romanov crossbred sheep and one exotic cross breed (goat/ibex). N. cuniculi was isolated from 80-88% of the animals under 1 month of age. Among older animals, the microorganism was isolated from 20.5% of the pure bred animals and 79.3% of the crossbred ones. This difference was significant (P less than 0.001) by the chi 2 test. The prevalence of N. cuniculi in the second age group coincides with the susceptibility of the breeds to respiratory pathology. This, we believe, is the first report of N. cuniculi involved in multiple cases of respiratory pathology and of a survey assessing the prevalence of this microorganism in small ruminants.
1987年3月至1989年3月期间，从38例大小反刍动物呼吸道疾病病例中分离出兔奈瑟菌。除5例外，其余所有病例中兔奈瑟菌均与其他潜在呼吸道病原体共同培养。开展了一项调查，以评估兔奈瑟菌在美利奴羊和阿瓦西纯种绵羊、阿瓦西/东弗里生羊和美利奴/罗曼诺夫杂交绵羊以及一个外来杂交品种（山羊/野山羊）咽部的流行情况。在1月龄以下的动物中，80-88%分离出了兔奈瑟菌。在年龄较大的动物中，纯种动物中有20.5%分离出该微生物，杂交动物中有79.3%分离出该微生物。经卡方检验，这种差异具有显著性（P<0.001）。兔奈瑟菌在第二个年龄组中的流行率与各品种对呼吸道疾病的易感性相符。我们认为，这是关于兔奈瑟菌涉及多例呼吸道疾病病例以及评估该微生物在小反刍动物中流行情况的首份报告。
