aureus nasal carriage rates were found 28% (41/144) in normal population‚ and 31.5% (12/38) in hospital laboratory personnel. Materials: * Mannitol salt agar (MSA) plate – Mannitol is a carbohydrate that can be used by some bacteria as a nutrient. The use of mannitol is important in identifying Stapphylococcus species. Mannitol salt agar contains 7.5% sodium chloride (salt) whereas‚ most media contains about 0.5% sodium chloride. Organisms that cannot tolerate a high salt concentration will not

nothing out of the ordinary except dehydration from the diarrhea. Lab tests showed that he had 13‚000 white blood cells/microliter of blood‚ and a methylene blue stain of his feces showed abundant neutrophils. His stool specimen was plated on MacConkey agar and several colonies on the plate turned bright pink after 24 hours. Based on symptoms and the lab results‚ he was treated with trimethoprim-sulfamethoxadole and intravenous fluid therapy. He improved quickly and was released after 24 hours.

Today‚ certain antibiotics are used in fighting certain diseases caused by pathogenic bacteria such as Salmonella enterica and Escherichia coli. However‚ due to the improper usage of these antibiotics and the increasing antibiotic resistance of the bacteria‚ a lot of the medicines commonly used before to fight the same bacteria are now considered ineffective and because of it‚ scientists try to find ways such as discovering new antibiotics or recommending to the citizens some procedures and ways

They are as follows: lactose fermentation on eosin methylene blue (EMB)‚ TSI (Triple Sugar Iron agar)‚ Phenol red sucrose‚ the SIM test‚ H2S by SIM‚ IMViC (indole‚ motility‚ voges-proskauer‚ and citrate)‚ Urease (urea broth)‚ PDase (Phenylalanine Deaminase)‚ Lysine Decarboxylase‚ and Ornithine Decarboxylase.

PEPSODENT THE PRODUCT Pepsodent‚ launched in 1993‚ was the first toothpaste with a unique anti-bacterial agent to address the consumer need of checking germs even hours after brushing. Pepsodent packs included a Germ Indicator in February-May 2002‚ which allowed consumers to see the efficacy in fighting germs for themselves. As a follow-up‚ in October 2002‚ Pepsodent Fresh & Pepsodent Family offered Dental Insurance to all its consumers to demonstrate the confidence the company has in the

Doctors use this to determine which antibiotics are needed to treat infections. b) The test is used to see how the antimicrobials impregnate on the disks are then placed on a plate which then are incubated to grow more bacteria it also allows the agar to diffuse over. Then a concentration gradient is created‚ if there is a zone of inhibition the the disks will show the growth being

Microbes are everywhere. Objectives: The experiment performed in the Lab was isolation of microbes taken from us and the environment. We used Nutrient Agar which is a growth medium used to culture microorganisms or small plants and Sabourand Dextrose Agar plates used to cultivate moulds and yeasts. The objective of it was to demonstrate that microbes are everywhere. We expected to find a variety of bacteria‚ moulds and yeasts. We were introduced to aseptic techniques as they help ensure that

on bacterial growth. By observing the effects of 5 different inhibitors including alcohol‚ bleach‚ soap solution and distilled water‚ it was determined what antiseptic or disinfectant was able to best inhibit this kind of bacterial growth. Nutrient Agar was poured into a Petri dish with four quadrants and then a pipette was used to place bacterial culture on top. Using forceps‚ a filter disc was dipped into each inhibitor and then into a separate quadrant of the Petri dish. The lid of the Petri dish
