Topic:Moraxella
Moraxella is a genus of bacteria that can be associated with various infections in horses, particularly affecting the respiratory and ocular systems. These bacteria are known to be opportunistic pathogens, often taking advantage of compromised immune systems or pre-existing conditions in equines. In horses, Moraxella species have been implicated in conditions such as keratoconjunctivitis and respiratory infections. The presence and impact of Moraxella in horses are subjects of ongoing research, with studies focusing on their pathogenic mechanisms, transmission, and potential treatment options. This page compiles peer-reviewed research studies and scholarly articles that explore the epidemiology, clinical manifestations, and management of Moraxella infections in equine populations.
Isolation of Moraxella spp. from horses with conjunctivitis in Southern Brazil. Infectious keratoconjunctivitis (IKC) is the most frequent ocular disease in livestock worldwide and is primarily caused by Moraxella bovis, M. ovis, and/or M. bovoculi. The economic impact of IKC is mainly due to ocular damage, which leads to weight loss, management difficulties, pain and discomfort, and cost of treatments. In horses, limited information is available on the association of Moraxella spp. with keratoconjunctivitis. The present report describes two cases of equine keratoconjunctivitis caused by members of the genus Moraxella. Both animals presented with lacrimation, conjunctivit...
Prevalence of ocular microorganisms in hospitalized and stabled horses. Microorganisms from normal eyes of hospitalized and stabled horses were identified, and the frequency of isolation was compared between the 2 groups. Using standard techniques, swab specimens from both eyes of 22 hospitalized horses and both eyes of 18 stabled horses were cultured for aerobic bacteria and fungi. Ninety-six aerobic bacteria and 57 fungi were isolated. The predominant bacterial isolates were gram-positive organisms, most of which belonged to the genera Corynebacterium, Bacillus, Staphylococcus, and Streptomyces. Gram-negative organisms comprised less than one-fourth of the bacte...
[Bacterial flora of the conjunctival sac of the horse]. The AA. report the results of taxonomic research conducted on the conjunctival sac of 59 horses for identification of the present bacterial flora. In the controlled animals, it was observed, at the level of the considered niche, a community constituted of normal bacterial populations, but not autochtonous in the significance they attributed from DUBOS et al., relative to the characterization of the indigenous microbiota of the intestine. The isolated normal bacterial flora seems to be constituted of: Micrococcus (subgroup 6 of Baird-Parker, M. luteus, Micrococcus spp.) isolated in 49,15% of th...
