Brucella melitensis biovar 1 was isolated from bovine milk samples from a herd in central Kenya, and Brucella abortus biovar 3 was isolated from aborted fetus materials and vaginal discharge fluids from cattle in central and eastern provinces of Kenya. All infections including those with B. melitensis were in cattle with reproductive problems kept in mixed herds indicating that cross infection occurs from small ruminants. Multiple-locus variable-number tandem repeat analysis genotyping revealed a close molecular homology of the B. melitensis isolates with an isolate from Israel and a close homology of the B. abortus isolates with an isolate from Uganda indicating that these genotypes have a wide geographic distribution. Infection of cattle with B. melitensis may complicate the control of brucellosis in this country.
马尔他布鲁氏菌生物变种1从肯尼亚中部一个牛群的牛奶样本中分离出来，流产布鲁氏菌生物变种3从肯尼亚中部和东部省份牛的流产胎儿材料及阴道分泌物中分离出来。所有感染，包括马尔他布鲁氏菌感染，都发生在混养牛群中有生殖问题的牛身上，这表明存在从小反刍动物的交叉感染。多位点可变数目串联重复序列分析基因分型显示，马尔他布鲁氏菌分离株与来自以色列的一株分离株有密切的分子同源性，流产布鲁氏菌分离株与来自乌干达的一株分离株有密切同源性，这表明这些基因型具有广泛的地理分布。牛感染马尔他布鲁氏菌可能会使该国布鲁氏菌病的防控复杂化。
