ABSTRACT Nature has been a source of medicinal agents for thousands of years and an impressive number of modern drugs have been isolated from natural sources Plants used for traditional medicine contain a wide range of substances that can be used to treat chronic as well as infectious diseases. Clinical microbiologists have great interest in screening of plants for antimicrobial activities and phytochemicals as potential new therapeutics. The use of plant extract for medical treatments is enjoying

Introduction: Antimicrobial agents are chemicals that are used against bacteria. There are many such agents available. Because there are many different situations where bacterial control is important‚ no antimicrobial agent is effective in all situations. For example‚ you wouldn’t use the same compound to fight an ear infection as you would use to sterilize surfaces in an Operating room. The situations are completely different. In one case‚ you are trying to assist the body to fight off an internal

Causes and spread of infection Micro-organisms that cause infections are known as pathogens. They may be classified as follows: Bacteria: minute organisms about one-thousandth to five-thousandths of a millimetre in diameter. They are susceptible to a greater or lesser extent to antibiotics. Viruses: much smaller than bacteria and although they may survive outside the body for a time they can only grow inside cells of the body. Viruses are not susceptible to antibiotics‚ but there are a few

NEUTRALIZATION TEST FOR VIRUS Neutralization of a virus is defined as the loss of infectivity through reaction of the virus with specific antibody. Virus and serum are mixed under appropriate condition and then inoculated into cell culture‚ eggs or animals. The presence of unneutralized virus may be detected by reactions such as CPE‚ haemadsorption/haemagglutination‚ plaque formation‚ disease in animals. The loss of infectivity is bought about by interference by the bound Ab with any one of the

Gut bacteria Gut bacteria are bacteria that are located in the gut. The gut is considered as any part of the gastrointestinal tract. The gastrointestinal tract includes the stomach‚ mouth‚ oesophagus‚ and duodenum. The gastrointestinal track has many different parts and each part contains different bacteria.There are 100 trillion bacteria present in the human body‚ most of them can be found within the gut and others can be found in the mouth‚ skin surface‚ urogenital tract and nose. Its structure

Strep Bacteria Strep is a bacteria that attacks your throat to be specific you tonsils and is very good at surviving in the throat that is why people remove there tonsils because if you remove them it’s a very low chance that you get strep. Or it will not be as bad as regular strep. “Some of the symptoms of strep are headaches‚ sore throat‚ nausea‚ cough‚ sneezing‚ headaches‚ swollen lymph nodes‚ a fever and other cold symptoms” (CDC).

The plate count agar‚ CFC agar and cetrimide agar are used and provided different evidences on the isolation of Pseudomonas from the soil experiment. Firstly‚ the plate count agar is a medium for the enumeration of viable organisms in food‚ water‚ waste water and also from clinical samples‚ and thus it is non-selective to any species. Whereas the CFC agar is a selective agar which contains reduced amounts of cetrimide but also cephaloridine and fucidin are added to allow the isolation of most Pseudomonas

(2 pts) Why are patients with cystic fibrosis prone to infections with Pseudomonas aeruginosa? Pseudomonas aeruginosa is an opportunistic infection that usually does not affect healthy patients‚ but is particularly detrimental in patients with cystic fibrosis. This is because they are antibiotic resistant to a certain extent. Paired with this‚ patients with cystic fibrosis have a decreased ability to produce mucous membranes‚ making it easier for biofilms associated with P. aeruginosa (Lyczak et
