The aim of the present study was to examine the suitability of the methodology which may disclose microbial diversity within feline conjunctivas of healthy cats and animals with conjunctivitis symptoms, using partial sequencing of the 16S rRNA gene.
To the best of our knowledge, there were no reports on the isolation of these species from cat conjunctivas. S.
Thus, its presence in cat conjunctivas can be explained by nursing cats with milk products.
Total RNA was isolated from conjunctivas harvested from WT or TSP-1 null mice (6, 8, and 12 weeks, n = 3 to 5) using TRIzol Reagent (Life Technologies, Carlsbad, CA) according to the manufacturer's instructions.
These mice spontaneously and progressively develop inflammation in the conjunctiva, with appearance of inflammatory infiltrates, tissue expression of Th1 and Th17 inflammatory cytokines, along with the development of inflammatory T cell effectors in their draining lymph nodes [17].
