as secondary transporters‚ catalysing drug-ion antiport. Efflux mediated resistance to biocides exhibit a wide range of substrate specificity. Quaternary ammonium compounds (QAC) have been defined in Gram-positive bacteria majority being in the Staphylococcus spp. Most of the determinants are plasmid-encoded SMR family exporters e.g. QacG‚ and QacH‚ although QacA/B is a MF family efflux system‚ through plasmid acquisition resistance occurs. Chromosomal efflux determinants of QAC resistance although

A 62-year old diabetic black man presents in the emergency room with a swollen left leg with areas of blanching and blue mottling. A "foul odor" is coming from a dressed wound. The physicians remove the dressing and a brownish fluid is seeping from a wounded area. The fluid contains what appear to be small bits of the tissue. No pus appears to be present. The wound has a strong "rotten" odor. Five days earlier‚ while at his work as a farmer‚ he caught the leg in his manure spreader‚ sustaining a

CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

to determine the potential and effect of banana shoot extract as antibacterial soap. ----------------------- ABSTRACT This study aimed the potential of banana shoot extract for the production of an antibacterial soap. The innovation in this study is the utilization of bio-product to use as an antibacterial soap at a very minimal cost. The researchers also aimed that the antibacterial soap could also be a moisturizer. They were still working

the structure of a gene What is antibiotic resistance? Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic. What is the scientific name for this process? methicillin-resistant Staphylococcus aureus Why is bacterial resistance a problem? Because they can cause diseases. What has led to an increase in the amount of bacterial resistance? Because the particles have grown over time. HIGHER Antibiotic-resistant bacteria Describe how a

of Public Health: Sir Alexander Fleming The discovery of penicillin by Sir Alexander Fleming is believed to be one of the greatest gifts every made to humankind. This discovery introduced the era of antibiotics to the world (Calvo‚ 2000). Staphylococcus aureus causes various pus-forming infections such as boils‚ styes‚ pneumonia‚ urinary tract infections‚ and more seriously osteomyelitis and endocarditis (Todar‚ PhD‚ 2008). The recurring theme of Sir Fleming’s career was to find a chemical substance

The food produced is processed using chemicals which in turn make people less immune and vulnerable to developing disease. Reports indicate that there are a significant number of people in the society suffering from various diseases (Shorter and David 155). Therefore‚ scientists worked to make antibiotics

Absract The aim of the prac was to identify and isolate Staphylococcus aureus and Eschericia coli in milk and salmonella in poultry.It was to investigate bacteriological quality of milk and poultry. Salmonella is areprobably the most important cause of food borne illness globally.Staphylocooccus aureus all cause food borne diseases if consumed in a contaminated milk. For milk a spread plate method was used and for poultry a streak method was applied using different Medias. All food contain a certain

INTRODUCTION Both scarring and nonscarring alopecias have been described with long-term use of epidermal growth factor receptor (EGFR) inhibitors. Current treatments revolve around anti-inflammatory agents such as topical corticosteroid ointments‚ creams‚ and intralesional injections to reduce follicular inflammation. Unfortunately‚ none of these therapies are universally effective. Here‚ we describe a case of erlotinib-induced alopecia refractory to intralesional and topical corticosteroids that
