Research output: Article


Histophilus somni is a Gram-negative, fastidious, facultative pathogenic bacterium. It had many former names (Histophilus ovis, Haemophilus agni, Haemophilus somnus) that were used parallel resulting certain confusion. The taxonomical position of the microorganism was not clarified for a long time, the name Histophilus somni was suggested a few years ago. H. somni is a coloniser of the respiratory and genital tract of cattle and sheep. It can cause local or generalised diseases, but asymptomatic carriers can also occur in both animal species. In cattle it can cause thrombotic meningoencephalitis, pneumonia and reproductive disorders, as well as septicaemia, orchitis and epididymitis in sheep. The authors reviewed the diseases caused by H. somni, the virulence factors and the antigens of the bacterium. Finally, they summarized the possibilities of protection against H. somni infection.
