at under a microscope it appears to be a cluster of what looks like purple circles. This shape is known as cocci. When grown on a TSA plate‚ Staphylococcus aureus appears to be yellow to opaque in color. S. aureus is known as one of the most resistant bacterium to multiple antibiotics and considered the most pathogenic. Everyone is susceptible to S. aureus with one way of transmission being from foods such as chicken‚ eggs‚ meat‚ and tuna which can all cause food poisoning. Another way of transmitting

Staph infections are caused by a staphylococcus bacterium‚ Staphylococcus aureus. S. aureus is a purple‚ cocci shaped cell with its morphological arrangements in grape-like clusters‚ it is determined by a bacteriological stain‚ known as the Gram stain. This determines it to be a gram positive bacterium. When grown on bacteriological media‚ S. aureus appears as a large white to golden colony. It is not very fastidious but it grows well‚ either aerobically or under anaerobic conditions and produces

health care workers have listed barriers and constraints that prevent them from practicing proper hand hygiene; therefore‚ leading to a low compliance rate. The effect of this low compliance rate leads to longer hospital stays‚ the development of resistant bacterial infections‚ and consequently a higher mortality rate among the patients. Research suggests that using alcohol based hand-rubbing solution is more effective in preventing nosocomial infection versus standard hand washing with antiseptic

every 20 minutes and are the same as the bacteria they came from‚ however they can sometimes mutate to adapt to their surroundings One such mutation is if they are exposed to too much antibiotics they could become resistant to the antivbiotic. Bacteria can mutate to become resistant in several ways. One is to deactivate the antibiotic before it reaches the inside of the bacterial cell‚ another is to pump the antibiotic out of the cell‚ yet another is to alter the protein on the bacterial cell so

Nursing Essay: Sample Reflecting on one’s Communication Skills Introduction Nursing students can enhance their learning through reflection that is‚ reflecting on a situation that involves nursing care (Parker 2006‚ p.115). In line with this thought‚ I shall reflect on an experience and discuss the communication skills I used or should have used during the patient encounter. I will use the three what model based on the work of Borton (1970) and Boud (1985) to help structure my reflection. Before

Dramatic increase in antibiotic resistance is an after effect of genetic material transfer from species to species and within species. Egression of Strains like VREF (vancomycin resistant Enterococcus faecalis)‚ MRSA (Methicillin resistant staphylococcus aureus) add complexity to current drug resistance problems. Use of broad spectrum antibiotics as medicational strategies transforms them from its normal state as gut commensal to leading nosocomial pathogens

Disruption of the normal gut flora from wide spread use of broad spectrum antibiotics is pivotal to the development and pathogenesis of RCDI. The standard treatment of oral Vancomycin while effective is not without significant side effects‚ while treatments using FMT shows promising high response rates with excellent safety records all the while restoring the gastrointestinal microbiome to a healthy state.
