Differential Sporulating Oocyst Count and Cross Protection Assessment of Two Immunologically Distinct Strains of Eimeria maxima; Guelph and M6 Strains
نویسندگان
چکیده
The members of the genus Eimeria infect a wide range of vertebrate hosts, such as swine, cattle, goats, sheep, rabbits, turkeys and chickens. It is now generally accepted that seven Eimeria species are recognised to parasitize the intestinal tract of the domestic fowl (Gallus gallus domesticus). Of all the Eimeria species that infect domestic fowl, Eimeria maxima is the most immunogenic species. Recent live oocyst vaccine failures to protect against infection with field isolates of E. maxima have demonstrated that there are immunologically distinct strains of this species. The degree of cross protection between the Guelph and M6 strains was evaluated by measuring oocyst shedding following homologous and heterologous infections. Furthermore, differential sporulating oocyst count for each strain was characterized in detail.

From the Macro to the Micro: Gel Mapping to Differentiate between Sporozoites of Two Immunologically Distinct Strains of Eimeria maxima (Strains M6 and Guelph)
Two immunologically distinct strains of E. maxima were examined in this study: the M6 strain and the Guelph strain. The differential expression between the sporozoites of the two strains of E. maxima was determined by image analysis of 100 μg of protein from each strain separated by standard one- and conventional two-dimensional polyacrylamide gel electrophoresis. In addition to differences in ...
متن کاملSequence-based genotyping clarifies conflicting historical morphometric and biological data for 5 Eimeria species infecting turkeys.
Unlike with Eimeria species infecting chickens, specific identification and nomenclature of Eimeria species infecting turkeys is complicated, and in the absence of molecular data, imprecise. In an attempt to reconcile contradictory data reported on oocyst morphometrics and biological descriptions of various Eimeria species infecting turkey, we established single oocyst derived lines of 5 import...
متن کاملA Novel Vaccine Delivery Model of the Apicomplexan Eimeria tenella Expressing Eimeria maxima Antigen Protects Chickens against Infection of the Two Parasites
Vaccine delivery is critical in antigen discovery and vaccine efficacy and safety. The diversity of infectious diseases in humans and livestock has required the development of varied delivery vehicles to target different pathogens. In livestock animals, previous strategies for the development of coccidiosis vaccines have encountered several hurdles, limiting the development of multiple species ...
متن کاملPrevalence and molecular characterisation of Eimeria species in Ethiopian village chickens
BACKGROUND Coccidiosis, caused by species of the apicomplexan parasite Eimeria, is a major disease of chickens. Eimeria species are present world-wide, and are ubiquitous under intensive farming methods. However, prevalence of Eimeria species is not uniform across production systems. In developing countries such as Ethiopia, a high proportion of chicken production occurs on rural smallholdings ...

Different species of Streptomyces are common in most types of soil. Some certain species are plant pathogenic especially on potato. This study was conducted to evaluate genetic diversity among some local Streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of Iran. Repetitive DNA elements (BOX, ERIC and REP) as genetic markers were used for diversity stu...
