Quantification of Microbes in Milk and Water Naomi Hall 10/20/14 BSC 381L H003 Group: Megan Baker‚ Katie Coe and Meagan Williams Abstract Coliforms are gram negative bacteria commonly found in the intestines of birds and mammals and are the most widely utilized indicators of fecal contamination. The purpose of this experiment was to test various water and milk samples for the presence of coliforms‚ specifically fecal coliforms. It was expected that fecal coliforms would be found in all

Ventilator Associated Pneumonia is one of the many nosocomial bacterial infections that patients in Intensive Care Units might acquire during their stay. VAP is the number one hospital acquired infection contracted in ICU’s. It occurs within 48 hours from prolonged oxygen therapy by endotracheal tube or tracheostomy. Intubation compromises the oropharynx and trachea by obstructing the normal airway. This allows easier access for microorganisms in gastric and oral secretions to enter the lungs and

continuous overuse or misuse of effective antibiotics has led to the ongoing emergence of new antibioticresistant pathogenic bacteria [23]. The continuous vicious cycle between rapidly increasing multidrug resistance and new drug development needs intervention. Bacteriophage therapy involves the utilization of a virus as a biocontrol agent to target and destroy disease causing bacteria and is predicted to be a practicable alternative therapy because of its long history of successful use in the eastern

Jordan. Following inoculation of red soils isolated from geographically separate areas of Jordan‚ Micrococcus luteus and Staphylococcus aureus were rapidly killed. Over the 3-week incubation period‚ the number of specific types of antibiotic-producing bacteria increased‚ and high antimicrobial activity (MIC‚ ∼10 μg/ml) was observed in methanol extracts of the inoculated red soils. Antibiotic-producing microorganisms whose numbers increased during incubation included actinomycetes‚ Lysobacter spp.‚ and Bacillus spp

The Characteristics of MRSA Staphylococcus aureus is a group of lactic acid-producing bacteria commonly found on the surface of the skin. When it penetrates a break in the surface‚ it induces an immune response that involves hydrogen peroxide and nitric oxide. For example‚ when it reaches the gut‚ it induces what is clinically referred to as enterocolitis‚ or infection of the digestive tract (Suzuki‚ 1994). Methicillin-resistant S. aureus (MRSA)‚ just like other S. aureus strains avoids such immune

Fleming was convinced that penicillin could not last long enough in the human body to kill pathogenic bacteria‚ and stopped studying it after 1931. He restarted clinical trials in 1934‚ and continued to try to get someone to purify it until 1940 The chemical structure of penicillin was determined by Dorothy Crowfoot Hodgkin in the early 1940s. Penicillin has since become the most widely used antibiotic to date‚ and is still used for many Gram-positive bacterial infections. A team of Oxford research

There are both good and bad bacteria’s and the good bacteria is known to helps fight against the bad bacteria that makes its way into our bodies. According to www.righthealth.com‚ less than 1% of bacteria are actually harmful to us. In fact‚ we couldn’t survive without bacteria in our body. Bacterial infection is
