Black Plague in the Middle Ages wiped out significant human populations. In the present‚ research in medicine has brought forth antibiotics – a way of stopping harmful bacteria from infecting a person. Growing concern is centered on the fear that the overuse of antibiotics will create different types of “super bacteria”‚ or bacteria resistant to multiple kinds of antibiotics. This fear is legitimate – mankind could be fast-forwarding the evolution of harmful viruses or bacterium‚ leading

of Streptococcus pneumoniae is the key factor in the significant increase of morbidity and mortality rate globally. For instance‚ the proposed research of studying the resistant strains of the Streptococcus pneumoniae can lead to a potential new antibiotic (Science and Social Responsibility - Dual Use Research). Despite the many benefits that may derive from such proposal‚ the potential risks of misuse could outweigh the

Identifying bacteria can furthermore be utilized in various other areas to knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for producing certain foods or antibiotics‚ to biological warfare. Their uses are infinite as are their abilities to develop and adjust to altering environments. That is why it is so significant to be competent to identify microorganisms. This study was conducted by applying techniques and

Amoxicillin is an antibiotic in the penicillin class that destroys bacteria. The mechanism of action of amoxicillin involves inhibition of bacterial cell wall synthesis. Therefore‚ it is valuable in destroying actively growing and cell wall synthesizing bacteria. Lysis of bacteria causes a lack of bacterial cell wall leading to death. Amoxicillin is used to treat several forms of infections of the nose‚ ear‚ skin‚ urinary tract‚ or throat and other infections caused by bacteria‚ such as bronchitis

Antibacterial activity of medicnal plants has turned out to be a global concern. Medicnal plants are very useful in treating various diseases. Antibiotics are an important class of pharmacological agents used for treating antibacterial infections. Although antibiotics were first isolated from fungi and bacteria but over the years more and more synthetic antibiotics has been synthesized‚ which are in great demand. This present study has been done to determine the antibacterial activity of Cannabis sativa

Chancroid‚ also know as Haemophilus Ducreyi‚ is a bacterium that attacks the skin tissue and produces an open sore. The sore appears in the region of the reproductive organs. The chancroid bacterium appears in both men and women. The symptoms of chancroid may vary between gender but nonetheless appear a few weeks after initial exposure. In men a small red bump will form near the genitals and convert to an open sore only a day or two later. For women four red bumps form in the genital region and also

The use of plant extract for medical treatments is enjoying great popularity since 1990s when people realized that the effective life span of antibiotic is limited and over prescription and misuse of traditional antibiotics are causing microbial resistance.

Just like potato chips‚ silly putty‚ and corn flakes‚ penicillin was an accident. Many people contributed to the bringing about of penicillin. The discovery of penicillin‚ the history of it are two very important subjects on how it became what it is today. First of all‚ penicillin was discovered by a bacteriologist Alexander Fleming. This scientist discovered it by accident. He went away for a while and when he came back a mold was covering all his petri dishes. Fleming did some testing with a particular

The difference observed in MICs against gram-positive and gram-negative bacteria could possibly due to their structural variation. Gram-negative bacteria have toxic outer membrane made of liposaccharides layer which makes them less susceptible to antibiotics and antibacterial agents than gram-positive bacteria (Guo‚ Ma‚ Guo‚ & Xu‚

MICROBIOLOGY COURSEWORK The effect of antibiotic concentration on bacterial growth Introduction Null Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth. Scientific Theory Bacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci‚ rod shaped bacteria are called bacilli‚ spiral shaped bacteria are called spirilla and
