| Causes of MRSA Infection |
|
Methicillin-resistant Staphylococcus aureus (MRSA) is caused mainly by antibiotic resistance. Staph bacteria are resident organisms on the surface of the skin and the anterior nose or nares. The problem begins once these organisms get into the body. Given below are some of the main causes of MRSA infection 1) Indiscriminate use of antibiotics: Using antibiotics for unnecessary reasons mainly viral infections has made staph bacteria resistant to normally used drugs. Viral infections like common cold are not responsive to antibiotics, yet they continue to be prescribed on a massive scale. 2) Mutation of Staph bacteria: As all organisms do, Staph bacteria have also adapted to continual attacks by antibiotics by mutating to a form that resist almost all powerful antibiotics. Usually bacteria that survive one antibiotic without getting killed manage to develop resistance quickly to all forms of antimicrobials barring the most lethal ones. 3) Trace antibiotics in water and food: Some amounts of trace antibiotics are consumed almost daily by the general population from the water as well as food they eat. Antibiotics are found in meat products like chicken, pork and beef. However it must be noted that proper dosage is important for animals as well and only excess drugs are shed off to contaminate various systems. 4) Poor hygiene: It is generally known that unclean conditions and poor hygiene are the main promoters of bacterial growth. Recent instances of Community-acquired MRSA bear testimony that sub-standard conditions trigger the growth and spread of MRSA. |
