Cutaneous microflora in horses with and without skin diseases
The cutaneous microflora of dogs without skin problems, dogs with seborrhoic diseases or allergic dermatoses is well evaluated. Surprisingly, less is known about the equine cutaneous microflora. This brandnew study from Cornell University gives some interesting new insights: For example, equine hyperkeratotic skin is significantly associated with an increased number of surface bacteria.

A retrospective study using light microscopy was performed to assess the prevalence of surface and follicular bacteria and fungi in skin biopsy specimens from 247 horses with inflammatory dermatoses and from 27 horses with healthy skin.

Cocci were found on the surface of specimens from 23% (95% confidence interval 18%, 29%) and 7% (95% confidence interval, 0%, 19%), respectively, of horses with skin disease and horses with healthy skin.

Of the nine dermatoses with at least 10 cases in our series of horses, bacterial folliculitis had a higher prevalence of surface bacteria (57%; 95% confidence interval 34%, 81%) than the other eight (which all had a prevalence < 30%).

There was a significant association between the prevalence of surface cocci and the extent of epidermal hyperkeratosis.

Cocci were found in the keratin of noninflamed hair follicles in only 2% of the horses with skin disease, and in none of the horses with healthy skin.

Fungal poroconidia were found on the surface of 4% of the horses with skin disease, and on none of the horses with healthy skin. Yeasts were not found.

Novel therapeutic approach for mares with suspected uterine tubal blockagemembers
Prostaglandin E2 is one of the traditional therapeutics in horses with suspected uterine tubal blockage. This study describes a modified approach: the laparoscopic transection of restrictive bands of the mesosalpinx as a useful adjunct to the topical application of prostaglandin E2. Can it be recommended?
