Methicillin-resistant Staphylococcus aureus

Meningitis is an inflammation of the brain and spinal cord, most often caused by viral infection, while bacterial and fungal infections are also possible causes. The first major recorded outbreak of Meningitis was in Geneva, in 1805. Meningitis can affect anyone, regardless of age, race or ethnicity, but the groups that are most susceptible to infection are infants between the ages of 6 and 18 months of age, children under the age of 5 years old, young adults, elderly people and anyone with an…

SSIs result from a variety of sources, both endogenous (such as bacteria living on the patient’s skin) and exogenous (outside the patient, such as from the equipment). Most SSIs and other nosocomial infections are caused by the bacteria Staphylococcus aureus (S. aureus). An important part of minimizing nosocomial infections is to perform the duties in the three…

What is SIBO? SIBO is an acronym for “small intestinal bacterial overgrowth”. While bacterium is naturally present in the digestive tract, in a healthy body, the small intestine contains relatively low levels of bacteria. The large intestine contains approximately 10-100 billion bacterial organisms, and bacteria is supposed to be at its highest concentration in the colon. Compared to this number, the small intestine is relatively sterile (containing a mere 100 thousand organisms). However,…

various species occur in pairs, short chains, and chains. Some are facultative aerobes, and some are anaerobic. Some species also are hemolytic, and others are non-hemolytic. Many species cause disease in humans. Streptococcus faecalis, a penicillin-resistant group D Enterococcus and normal inhabitant of the GI tract may cause infection of the urinary tract or endocardium. Streptococcus pneumoniae, formerly Diplococcus pneumoniae, causes a majority of the cases of bacterial pneumonia in the…

RESISTANCE 2 The genus Staphylococcus is a common inhabitant of the skin and mucous membranes. Staphylococci are organisms that are gram positive clusters or tetrads. They stain purple with the Gram’s stain. The organisms lack spores, flagella and some species are encapsulated. There are about 30 species of Staphylococcus species. Some of the pathogens include…

organisms for present study is MRSA, a microorganism which has developed resistance to the almost all types of antibiotics. Staphylococcus aureus the catastrophic effects of staphylococcus have affected human kind since very early history and it is believed that 6th plague of Egypt which was named as “incurable boils” was also caused by staphylococcus. But the name staphylococcus was given after the two Greek words stands for staphylos (grips) and kokkos (seeds/berry) in 1882 by the Scottish…

lysozyme etc. The production of these substances ensures that the microorganisms are destroyed before they get an opportunity to cause infections [4]. However, S. aureus has developed mechanisms, which enhance the evasion of the host immune system. The host’s body produces effector proteins after microbial invasion; nevertheless, S. aureus produces molecules that inhibit these proteins. Another mechanism used by the microbe involves binding of immune regulators produced by the host through the…

Staphylococcus Aureus How it started S. aureus belongs to the Staphylococcaceae family. This special germ is a major source of pus. It was discovered and named by Scottish surgeon Alexander Ogston in 1880. He was distressed with the high rate of post- operative mortality and unwilling to accept death as a likely outcome of surgery. He was a fan and follower of the value of antisepsis advocated by Joseph Lister. Ogston abandoned the contemporary teaching that pus formation was a necessary stage…

it is very common in athletes who play sports like American football or Rugby. And following simple habits such as washing your hands frequently can ultimately reduce Methicillin-Resistant Staphylococcus Aureus by 40%. The name Staphylococcus Aureus comes from the time when this disease could be cured by the antibiotic Methicillin. But as time went on the disease kept on transforming…

Methicillin Resistant Staphylococcus Aureus (MRSA) was first discovered as the superbug in the United Kingdom in 1961 and because of its nature of resisting antibiotic treatments, it was difficult to treat this bacterium (Sanders, 2012). Staphylococcus Aureus (S. Aureus) is one of the normal floras that make ecological niches on certain body parts but usually on the anterior nares. It is a commensal organism that can also be pathogenic if its ecological niches’ such as body’s defense system…
