A typical actinobacillosis in an adult friesian cow

Aleri JW, Abuom TO, Mulei CM. "A typical actinobacillosis in an adult friesian cow.". 2011.


Actinobacillosis due to Actinobacillus lignieresi, has been reported in domestic animals including cattle, sheep, goats, buffalo, horses and dogs (Carmalt et al., 1999; Kennerman et al., 2006; Muhammad et al., 2006; Brown et al., 2007). The causative agent is a gram-negative aerobic rod and a normal inhabitant of the gastrointestinal tract of ruminants (Radostits et al., 2007; Smith, 2009). The most frequent clinical presentation is granulomatous or pyogranulomatous lesion of the tongue or subcutaneous tissues in the head and neck region. A typical manifestation of the disease have been reported affecting other body tissues / organs usually associated from lacerations, dehorning, nose-rings, intravenous injections and lymphadenitis (Aslani, et al., 1995; Holzhauer and Roumen, 2002). Outbreaks of the disease have also been reported (Campbell et al., 1975; Nakazawa and Azuma 1977). This paper outlines an atypical case of actinobacillosis of soft tissue swelling of the head in a cow without any exudation from the lesion, which is a challenge to confirming the etiological agent and treatment.
