Mixed infestations with Linognathus africanus and Bovicola caprae were diagnosed in a lot of 20 goats from a flock of 40, belonging to a farm from the Universidade Federal Rural do Rio de Janeiro, Rio de Janeiro, RJ (22 degrees 44'38''S and 43 degrees 42'27''W). Animals were of both sexes, varied ages and different breeds (half blood Saanen/Boer, Saanen, cross breeds), were examined in April of 2004. With an exception of one goat, parasitized only by L. africanus, the remainders 19 (95%) were infested by the two species lice. Of 69 (71%) specimens of L. africanus and 28 (28.9%) of B. caprae collected the ratio female:male for L. africanus were 4.6 (23:5), while for B. caprae were 4.8 (57:12). The absence of L. africanus in recent surveys carried out in the semi-arid regions of the Northeast Brazil where more the 60% of examined goats were parasitized by B. caprae suggests that the adaptation to the climatic variation might be different for the two species.
在里约热内卢联邦农村大学（位于里约热内卢，RJ，南纬22度44分38秒，西经43度42分27秒）的一个农场的40只山羊群中，对20只山羊进行检查后诊断出存在非洲林虱和山羊毛虱的混合感染。这些动物有公母两性，年龄各异，品种不同（半血萨能/布尔山羊、萨能山羊、杂交品种），于2004年4月接受检查。除了一只仅被非洲林虱寄生的山羊外，其余19只（95%）被这两种虱类感染。在收集到的69只（71%）非洲林虱标本和28只（28.9%）山羊毛虱标本中，非洲林虱的雌雄性比例为4.6（23:5），而山羊毛虱的雌雄性比例为4.8（57:12）。在巴西东北部半干旱地区最近进行的调查中，超过60%接受检查的山羊被山羊毛虱寄生，而未发现非洲林虱，这表明这两种虱类对气候变化的适应性可能不同。
