Staphylococcus aureus

Introduction / Purpose: Ventilator-associated pneumonia (VAP) is the most common nosocomial infection in the intensive care unit (ICU). It caused prolonged hospital stay and increased mortality. In this study, we aimed to investigate the rate of VAP, causative microorganisms and their antibiotic susceptibilities. Materials and Method: This retrospective study included patients that admitted in 12-bed ICU between January 2013 and December 2014. Centers for Disease Control and Prevention criterias…

Once the human body has been exposed to, and therefore infected by foreign bacteria, the infectious agents travel through the body via the bloodstream and the lymph nodes. After this infection occurs these bacteria now, in the body are planktonic. This means they are individual, free swimming, and virtually functioning as single celled organisms. When these bacteria are threatened by the host’s immune system or antibiotics they form biofilms. A biofilm is a thin coating of organic as well as…

Purpose Statement: The purpose of this experiment was to determine the Gram stain of the certain slant cultures we used in class, Escherichia coli and Staphylococcus aureus, under a microscope. Since it is the most important staining procedure in microbiology, it is used to distinguish between gram-positive and gram-negative organisms. The gram-positive cells stain purple, and the gram-negative stain a pinkish color. This staining is a differential stain that allows is used to identify the…

Results: In order to identify the gram positive isolate in the unknown #260 broth, I observed the bacterium under the microscope, created a stock culture, and conducted a variety of biochemical tests. First, I prepared a gram stain of the mixed culture using aseptic technique, shown in Figure 1, and found two different bacteria. There were too numerous to count purple cocci in clusters, pairs, and some single cells, which I identified as the target isolate. The other bacteria present a pink…

silkworm Bombyx mori L. like other organisms (Legay, 1958). In the present study, the antibacterial activity of sericin from sporlac, treated silkworm against five human bacterial pathogens such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pyogenes…

Chart. Catalase test is positive result, so I got two Strike Charts which are Staphylococcus and Micrococcus, Planococcus and Sporosarcina from Mrs.Terri. I need to figure out my unknown cell trough theses charts. Analysis 05-02-16 The Gram positive unknown is identified to be cocci and Catalase positive result. Through this test, my result is narrowed Micrococcus, Planococcus, Sporosarcina, and Staphylococcus. This deduction is reached with several bits of evidence. Firstly, a…

Serratia marcescens utilizes the sugars very slowly. This can be accredited to the fact that the slant is pinkish but the bottom of the test tube is still yellow. In our biochemical analysis of gram positive bacteria, we learned that only Staphylococcus aureus…

staph infection or also known as MRSA. [show pic of MRSA] 2. Sub point: According to Aslantaş, Ö., & Demir, C. (2016). “Investigation of the antibiotic resistance and biofilm-forming ability of Staphylococcus aureus from subclinical bovine mastitis cases” they point out, “ In our study, Staph. aureus isolates showed higher rate of resistance to penicillin (45.5%)”…

demonstrated immediate, persistent, broad-spectrum antimicrobial effectiveness and utility in clinical health care settings. [44] Braid, et al (2002) carried out study on the antibacterial activity of triclosan-impregnated storage boxes against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa,…

These days, it seems everyone likes to keep it hair-free down there. But lately we read some stories that ask men and women to let their pubic hair grow. Since it is all a matter of preference, but let’s get the facts straight that it isn’t very important to wax or shave your pubes? Actually, you may event want to abstain from doing it, because pubic hair aren’t there without a purpose. Because shaving/waxing down there can pose a lot of health risk that you’ve never heard of. First things…
