Bacteria Essay

Scientists have not found antibiotics that are effective since the pathogens are multi-drug resistance. Multi-drug resistance is top three on global public health that are mostly caused by nosocomial infections (hospital-acquired infection caused by bacteria, fungal and viral, parasites and other pathogens). The six pathogens are Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumonia, Acinetobacter baumannii, Pseudomonas aeruginosa, and several species of Enterobacter. Instead of…

Under 100x magnification – a view of purple rod shaped bacteria/bacilli; some appear as either single rods or paired rods (diplobacillus). Yoghurt prepared – under 40x magnification Yoghurt prepared – under 100x magnification * Fresh yoghurt. Under 40x magnification – a view of loads of bacteria moving about with undefined shapes. Under 100x magnification – an indistinct view of loads of varied bacteria moving about, such as diplococci, streptococci, staphylococci,…

Is It Safe To Go To A Pedicure Spa? For the Science Fair, my question will be, “Is it safe to go to pedicure spas?”. To answer my question, I will test the bacteria levels at pedicure stations in local salons. I will get permission from the salons where I plan to obtain the samples and identify them only as anonymous sources. I will go to local business establishments and collect samples from the pedicure stations using materials such as petri dishes, sterilized swabs and other research…

the rate of E. coli growth over 100 minutes in a heated liquid growth medium. The prediction is that the control E. coli culture will grow at a faster rate exponentially over 100 minutes than the experimental bacteria culture. Consequently due to heat application, the experimental bacteria will not grow over the 100 minutes, and will either move into G0 of its cell cycle or will produce descending results as cell death occurs. The null hypothesis for this experiment is that the experimental E.…

wrong bacteria, do not treat the viruses, and are often overused. Antibiotics were created in order to fight off bacterial infections in the body, in the early 1940’s. According to, A Brief History of Antibiotics, “Alexander Fleming, was the first scientist to discover one of the first antibiotics known as penicillin” (BBC…

different proteases. These proteases may be membrane bound or extracellular. Among membrane bound proteases CaaX proteases are present in both the strains. In S.gordonii these proteases are known to play a role in protein transportion and protection of bacteria from bacteriocins. Protease HMPREF0389_00122 is present in the extracellular fraction of D-62D srain and this is known to have collagen peptidase function. This protease might be responsible for the damage of the connective tissue which…

The use antibiotics in raising livestock has contributed negatively to the effectiveness of antibiotics for humans and needs to be regulated by the FDA. Over the past 80 years the use of antibiotics and other treatments has grown and expanded too many practices in how people produce food. Farmers use pesticides on vegetables and plants to kill off insects to keep production levels high. Livestock farmers use antibiotics to enhance the growth and health of animals. Unlike pesticides, antibiotics…

Introduction: Viral infections can affect many things, including bacteria. When bacteria undergo infections from a virus that virus is called a bacteriophage. After a bacteriophage infects a bacteria it can create two different phases, the lytic or lysogenic cycles. During a lytic stage the bacteriophage causes death to the bacteria. When this happens on an agar plate covered in bacteria it creates a clear spot known as a plaque. Each plaque is created by one virus so from the number of plaques…

antibiotic that would eventually save countless numbers of lives (“Discovery” par. 4). Since then, many new antibiotics have been introduced in the market; however, they are misused frequently, thus creating a shortage of effective antibiotics as bacteria develop resistance to overused antibiotics. Many people believe antibiotics…

antibiotic resistance present in humans. One major factor is that the antibiotics fed to animals are being transferred to humans through meat consumption. There were several cases of major outbreaks due to human bodies being resistant to a strain of bacteria. There have been a handful of evidence linking the cause to antibiotics fed to animals. Many argue that the government is not regulating the amount of antibiotics animals receive which leads to extreme cases of antibiotic resistance.…
