bacteria that may live as individual cells‚ or pair up to form chains or bunches. Staphylococcus and Streptococcus are the most common bacteria in this group and usually are Gram-positive. These bacteria perform useful functions in the body and environment but they can be harmful. Staphylococcus aureus can cause impetigo (skin infection)‚ scalded skin syndrome and food poisoning‚ while Streptococcus pyogenes may cause tonsillitis and strep throat. Bacillus Bacillus refers to rod shaped bacteria that

Experimental Methods In this lab‚ we use the procedure from Chemically Defined‚ Complex‚ Selective‚ and Differential Media. We divide the agar plates that have the unknown in third‚ write our initials‚ and date on the bottom of the agar plate. We also divide the agar plates into quadrants‚ label each organism in their quadrant‚ write our initials‚ and date on the bottom of the agar plates. We flame the loop and let

accepted demonstration of bacterial transformation‚ where a bacterium distinctly changes its form and function. Griffith succumbed to his death around the year 1941 due to the air raid. His Purpose and what he derived? Griffith showed that Streptococcus pneumonia‚ could transform from one strain into a different strain. The observation was attributed to an unidentified transforming principle of transforming Factor. This was later identified as the stuff of life “DNA” The Experiment Griffith’s

Tetanus Tetanus is a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin‚ a neurotoxin produced by the Gram-positive‚ rod-shaped‚ obligate anaerobic bacterium Clostridium tetani. Clostridium tetani spores can be found most commonly in soil‚ dust and manure‚ but also exist virtually anywhere. If deposited in a wound the neurotoxin interferes with nerves that control muscle movement. The signs and symptoms

maggot therapy mechanisms of action Medicinal maggots have at least two confirmed beneficial effects on wounds that can be supported by laboratory investigations. They are debridement‚ or elimination of necrotic tissue‚ and removal of pathogenic bacteria. There is moreover‚ evidence from recent studies that they may also accelerate wound healing by promoting the formation of granulation tissue as suggested by the early literature‚ Wound debridement activity Necrophagous larvae feed on the dead
