The isolation, purification, and identification of nearly pure HA have been the center of scientific interest for many decades. The bacterial production of HA by Streptococcus equi [221] and Streptococcus zooepidemicus [222] enabled it to be produced in larger quantities than could be achieved by extraction methods alone. HA produced by S. equi has a lower molecular weight than does HA produced by S. zooepidemicus, which has a MW of about 1.8-2x 10 Da with a yield of... 

Endometritis in mares may be associated with at least four clinical s)mdromes. It can be caused by sexually transmitted infections, such as Taylorella equigenitalis (contagious equine metritis). Pseudomonas aeruginosa and Klebsiella pneumoniae. Pseudomonas and Klebsiella spp. may also be present in the fecal and genital flora. Chronic uterine infection with Streptococcus equi subsp. zooepidemicus and Escherichia coli are often associated with contamination of the uterus by fecal and genital flora.

Streptococcus equi subsp. equi, which is the causative agent of Strangles, was adsorbed onto poly-e-caprolactone microspheres with chitosan-modilied surfaces (Florindo et al. 2008). After subcutaneous immunization of mice, the formulations induced higher lymphokines levels than did the free antigen, in accordance with cellular and humoral immune responses, successfully activating the paths leading to Thl and Th2 cells. More pronounced responses were observed with chitosan-surface-modifled PCL microspheres than those of the unmodified formulations.

Streptococci species. Streptococcus equi is a commercially used microbe to produce hyaluronic acid using complex medium.Vazquez et al., proposed a seafood by-products-based culture medium for the production of hyaluronic acid by Streptococcus zooepidemicus.The medium contains mussel processing waste as carbon source and tuna peptone as protein substrate and thus can be a cheap alternative to synthetic peptone-based medium. Now, genetically modified strain with high productivity of hyaluronic acid is in place to meet the challenges with conventional fermentation.

At the present time such non-haemolytic and hyaluronidase-negative strains are usually obtained by non-direct chemical and UF-induced mutagenesis, followed by selection or cloning of the hyaluronidase gene in order to transform Streptococcus sp. into non-pathogenic bacteria [33]. Of all the hyaluronan producers, the most appropriate strain is streptococcus of the group C, that is Streptococcus equi because it produces the highest yield of HA [30].
