Ovine keratoconjunctivitis was successfully reproduced in lambs under 1 year of age, in four separate transmission trials, by the use of mycoplasma isolates obtained from field outbreaks of ovine infectious keratoconjunctivitis. Mycoplasma isolates used in one of these trials, were identified as M. conjunctivae by means of immunofluorescence. Mycoplasma was isolated from approximately 87% of fi...

Infectious bovine keratoconjunctivitis (IBK) involves multiple factors and opportunistic pathogens, including members of the genus Moraxella , specifically M bovis . The causal role is clear, where presence virulence that facilitate colonization (pili) host cytotoxicity (RTX toxins) are well characterized, IBK has been reproduced in many models. Experimental infection with bovoculi failed to re...

Acholeplasma laidlawii can be isolated from cattle environments and different body sites of bovines. It is still under evaluation if A. acts as a primary pathogen. Here, we present the whole-genome sequence conjunctiva heifer with infectious bovine keratoconjunctivitis.

A concentrated bacterial culture supernatant from the hemolytic Moraxella bovis strain UQV 148NF was used to immunize mice and generate monoclonal antibodies (MAbs). One, MAb G3/D7, neutralized the hemolytic activity of M. bovis and recognized a 94-kDa protein by Western blot analysis in hemolytic M. bovis strains representing each of the different fimbrial serogroups. Exposure of corneal epith...

Chloramphenicol, chlortetracycline, streptomycin, and sulfisoxazole prevented keratoconjunctivitis in rabbit eyes infected with Shigella flexneri. The route of administration of the agent and the dose were important variables in controlling the infectious process. This assay system appears to be a useful technique for the in vivo evaluation of chemotherapeutic agents.

Moraxella bovoculi is a recently identified species, recovered from the bovine eye, which is under investigation as an etiological agent of infectious bovine keratoconjunctivitis. A draft genome sequence of the Moraxella bovoculi type strain 237(T) has been determined to identify features that may be important during host colonization.
