Testing The Effect Of Grapefruit Seed Extract (Gfse) On The Mastitsis-Causing Alga, Prototheca, Kendra Janelle Macdonald
Testing The Effect Of Grapefruit Seed Extract (Gfse) On The Mastitsis-Causing Alga, Prototheca, Kendra Janelle Macdonald
Honors College
Mastitis is an inflammation of the mammary gland that costs the United States dairy industry between $1.7 and $2 billion annually [9]. Approximately 97% of mastitis infections are caused by bacteria, which can be treated with antibiotics [2]. However, mastitis infections can be caused by the alga, Prototheca. Specifically, it is P. zopfii (genotype 2) and P. blaschkeae that have been found in cows with mastitis [7]. There are currently no approved treatments for protothecal mastitis. The following experiments a tested the effects of grapefruit seed extract (GFSE) on P. zopfii (genotype 2) using spectrophotometry and plating techniques. GFSE was …
Equine Serum Antibody Responses To Streptococcus Equi And Streptococcus Zooepidemicus, Rafaela De Negri
Equine Serum Antibody Responses To Streptococcus Equi And Streptococcus Zooepidemicus, Rafaela De Negri
Theses and Dissertations--Veterinary Science
Streptococcus zooepidemicus (Sz) and Streptococcus equi (Se) share 98% DNA sequence homology, but display different pathogenic properties. Infection by one organism does not cross-protect against the other. To better understand pathogenic differences between these organisms and gain information about which proteins are expressed in horses infected experimentally with Se, intrauterine Sz or naturally with respiratory Sz we compared antibody specificities of convalescent sera using ELISA. These comparisons were based on sets of 8 and 14 immunoreactive recombinant proteins of Se strain CF32 and Sz strain NC78, respectively. Sera from donkeys that were previously naturally affected with strangles and later developed …
Evidence For The Maturation Of Cellular Immune Responses In Equine Infectious Anemia Virus-Infected Ponies, Chong Liu
Theses and Dissertations--Veterinary Science
Equine infectious anemia virus (EIAV) has been used as a model to investigate protective mechanisms against lentiviruses. Unlike other lentiviruses, EIAV replication can be eventually controlled in most infected horses leading to an inapparent carrier state free of overt clinical signs which can last for many years. Maintenance of this carrier state is absolutely dependent on active immune responses as evidenced by the fact that immunosuppressive drugs can induce the recurrence of disease. However, the immune mechanisms that are responsible for this control of infection are not yet identified. As the resolution of the initial infection is correlated with the …
