DIFFERENT TYPES OF AGAR Mac Conkey‘s Agar plate MacConkey (also McConkey) agar is a culture medium designed to grow Gram-negative bacteria and stain them for lactose fermentation. It contains bile salts (to inhibit most Grampositive bacteria‚ except Enterococcus and some species of Staphylococcus)‚ crystal violet dye (which also inhibits certain Gram-positive bacteria)‚ neutral red dye (which stains microbes fermenting lactose)‚ lactose and peptone.

Other problems associated with regulatory pressures are also demonstrated by the fact that Medicare is planning to no longer reimburse for hospital-acquired infections– particularly Methicillin Resistant Staphylococcus aureus (MRSA). The Center for Disease Control suggests that there are two main ways to contract any of the common viral illnesses. Contracting may occur through coughing or sneezing with airborne illness (known as “droplet spread”)‚ or through

Early bleb related endophthalmitis is caused by Streptococcus epidermidis‚ Staphylococcus aureus‚ Propionibacterium acnes and other gram positive organisms. Late onset endophthalmitis is caused by Streptococcus‚ gram negative organisms such as Haemophilusinfluenzae‚ Moraxella‚ Pseudomonas and Serratia The treatment of bleb related endophthalmitis should be more aggressive than on the lines of edophthalmitis per se as the prognosis

March 2013; Accepted 10 May 2013 Abstract: Bacterial resistance to commonly used antibiotics is constantly increasing. Bacteria particularly dangerous for human life are methicillin-resistant Staphylococcus aureus‚ vancomycin-resistant Enterococcus faecium and fluoroquinolone-resistant Pseudomonas aeruginosa. Hence‚ there is an incessant need for developing compounds with new modes of action and seeking alternate drug targets. In this review‚ the authors discuss the current situation of antibacterial

the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The focus of this paper will be on the description of the just one of the three bacteria and some of its effects on humans. The first test done was a differential stain (gram stain) to determine the unknown microorganism cell shape and arrangement. The gram staining is done by first putting a sample of the unknown bacteria on a slide and

organism ferments mannitol‚ an acid will be produced turning the indicator yellow. This is an indication that Staphylococcus aureus ferments with mannitol. Unknown #11 did not ferment with the mannitol‚ as the colonies did not show any yellow coloration‚ thus eliminating the possibility that the unknown organism is a type of Staphylococci.

Infection is the most important reason of morbidity and mortality in burns. Staphylococcus aureus and Pseudomonas aeruginosa are the most frequently colonizing bacteria whereas group-a beta-hemolytic streptococci are the most virulent bacteria and anaerobic bacteria as well as fungi are also common‚ viral infection is less prevalent (3‚ 4).
