Description and significance
Campylobacter fetus is a spiral slender, spirally curved bacterial pathogen, enclosed with an S layer of special crystalline surface proteins. (Their unique function will be discussed later) . It is a gram negative species holding two membranes and a thin cell wall in between. Since it is a pathogen, it can reside anywhere in the human body. The campylobacter S layer proteins were found to have a virulence factor in resistance to the host immune defense mechanisms. Two subspecies were then suspected to exist in the campylobacter. One was Campylobacter fetus subsp. fetus and Campylobacter fetus subsp. Venerealis. To further investigate the genetic diversity among C. fetus strains of different origins, multiple genetic analyzing were used such as polymorphic DNA (RAPD), pulsed-field gel electrophoresis (PFGE), and DNA-DNA hybridization. I t was also mainly found that its natural habitat of C. fetus subsp. fetus is the intestinal tract of cattle, but it can also cause abortions.
Genome structure
Campylobacter Fetus was completely sequences and was found to have 1820 genes. It has a circular DNA. Its genome length is 1,773,615 nt.GC content is 33%, coding sequence is 90%.It as 3441 proteins. The two stains that were found were dividing based on their lipopolysaccharide (LPS) composition. These unique stains must contain conserved sequences so to check their unique versus mutual sequences we used gel electrophoresis. This helped answer the unique method of this pathogen in changing its S layer proteins. Different study reported the different multiple somewhat homologous and highly conserved surface layer proteins, tightly packed in this species. They encode for the 97-149 kDa. They attach to the N terminus of the cell wall lipopolysaccharide non covalently.
Cell structure and metabolism
