There is anecdotal evidence implicating Chlamydia spp. in some cases of follicular conjunctivitis, and both Moraxella equi some Mycoplasma spp. may be involved in external ocular disease in the horse (Lavach 1990). The role of anaerobes in equine ocular disease has not been investigated extensively, although Clostridium perfringens has been isolated from corneal ulcers in two horses (Rebhun et al 1999). 

Chlortetracycline ointment (1%) is indicated for conjunctivitis or keratoconjunctivitis where Chlamydia or Mycoplasma spp. are the suspected primary pathogens. Topical chloramphenicol is reported to be effective against clostridial infections of the cornea (Rebhun et al 1999). 

Viruses, Mycoplasma spp., Chlamydia spp., and fungi are recognized causes of pneumonia syndromes in all age groups. The designation atypical pneumonia, distinct from the typical bacterial pneumonia seen most commonly in adults, has been used to describe the illness caused by many of these agents. " ...

A number of gram-positive bacteria, as well as gram-negative, contain cell surface hair-like projections termed fibrillae. In Streptococcus pyogenes bacteria, these structures are composed of protein and lipoteichoic acid complexes. The lipid portion of the lipoteichoic acid complex appears to be the ligand structure that binds to the complementary protein or glycoprotein host cell sites. Mycoplasma spp. and some filamentous bacteria are able to attach by their terminal of attachment structures to host cells, specifically epithelial cells [6,8].
