Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

septicemia. (Strand & Shulman 1988) As shown in Table 1.‚ many organisms have developed resistances to commonly used antibiotics. The difference between the standard strain of Klebsiella pneumoniae and the extended spectrum betalactemase (ESBL) strain‚ for example‚ is striking. 12 antibiotics had greater than or equal to 95 percent effectiveness against the common K. pneumoniae strain‚ while only 2 antibiotics were as effective against the ESLB strain. P. aeruginosa and K. pneumoniae are only two

dependency on antibiotics‚ E. Faecalis is becoming feared due to its intrinsic antibiotic resistance (Wesley Glick‚ 2000). This strain is naturally immune to weaker levels of penicillin because of its ability to synthesize cell wall components in the presence of penicillin. Instead of allowing this antibiotic to destroy the cell wall‚ E. Faecalis produces penicillin-binding proteins that inhibit penicillin from disintegrating its cell wall (Susan L. Fraser‚ 2012). Thus a more effective antibiotic must

resistant to the antibiotic vancomycin. Enterococci infections are the most common type acquired by hospitalised patients. Vancomycin was the last-line antibiotic for hospital treatment of serious methicillin-resistant staphylococcus aureus (MRSA) infections according to Collignon (2002‚ p. 327). These enterococci have become resistant because of the overuse of the antibiotics that control these infections. Cross-resistance between classes and exposure to one antibiotic may promote resistance to others

One of the most serious infections is called Methicillin-resistance Staphylococcus aureus (MRSA).

It is a constant problem because of the misuse of antimicrobials in farms‚ disease treatment‚ growth promotion in domestic livestock‚ and the increasing problem of antimicrobial resistance. Current research is being conducted with bacteriophages because they have been identified as a prospective alternative bio-control method to control Salmonella contamination in a variety of foods.
