Divide the learners into 2 teams. 1 team will be given a set of artificial fingernail tips to wear along with instructions on how to put them on and the other team of learners will not be given artificial fingernail tips. Give both groups bowls of flour and water and instruct them to make small balls of dough with these materials. Do not allow the first group to remove their fingernail tips and do not allow

Unit 21: Biomedical science techniques Assignment one Task one Bacteria Virus Fungi Protozoa Structure Structure of bacteria includes a cell wall made up of glycoprotein murein, a plasma membrane made up of proteins, phospholipids and carbohydrates which make a fluid mosaic. It also consists of cytoplasm, ribosome which is small granule made up of protein and RNA, plasmid that are a small circle of DNA, flagella which has a rigid rotating tail, Pilli which has small protein appendages and

including bacteria, combined, cause or contribute to 99,000 deaths each year. In Europe, where hospital surveys have been conducted, the category of Gram-negative infections are estimated to account for two-thirds of the 25,000 deaths each year. Nosocomial infections can cause severe pneumonia and infections of the urinary tract, bloodstream and other parts of the body. Many types are difficult to attack with antibiotics, and antibiotic resistance is spreading to Gram-negative bacteria that can infect

Fundamentals of Biotechnology: BS934 Assignment title Antimicrobials Student Number 1464986 Word Count 2470 The article will initially cover conventional antibiotics and how their abuse led to antibiotic resistance in bacteria. Alternative antimicrobials will be reviewed by taking into consideration their mechanisms of action and how they can represent a viable option to address the issue of antibiotic resistance.

population, including food pathogens, during sprouting. Population as high as 109 CFU/g have been reported in sprouts obtained from retail stores (Patterson et al, 1980, Prokopowich et al, 1991). Many published studies have shown that pathogenic bacteria not only survive but can also grow on sprouts under favorable conditions (Portnoy et al., 1976, Harris et al., 1986, Steinbruegge et al., 1988, Abdoul-Raouf et al., 1993, and Farber et al., 1998). The seeds are generally

This essay is about superbugs that can be found in a hospital setting. Because one out of every twenty patients admitted to a hospital will contract an infection according to the Center for Disease Control and Prevention (CDC), it’s important to understand the science behind them. These superbugs are methicillin-resistant Staphylococcus aureus (MRSA), Clostridium difficile (C. diff), Vancomycin-resistant Enterococci (VRE), Carbapenem-resistant Enterobacteriaceae (CRE) and Carbapenem-resistant and

Type and class of Pathogen Sulfonamides have been in use since the 1930's , these drugs are effective against both gram- negative and gram - positive bacteria. Sulfonamides are know as broad spectrum antimicrobial drugs; they are effective against a wide variety of microorganisms most Enterobacteriaceae, Chlamydia trachomatis, Nisseria, Haemophilus influenzae,, Norcardia, E.Coli , P. mirabilis some

CHAPTER II REVIEW OF RELATED LITERATURE Infectious diseases represent a serious health problem today and account for one third of all deaths worldwide (Perumal et al., 2012), and herbal medicine has been used in many parts of the world as a rich tradition for the treatment of these infectious diseases (Titilope et al., 2012), both infectious and non-infectious. Attah et al. (2012) makes similar claims with the evaluation and development of compounds from similar claims with the evaluation and development
