Bacteria Essay

can bleed easily, this makes the cleaning of the teeth more difficult, and if it remains untreated, the inflammation affects also the jaw bone [18]. While Periodontitis is not just chronic inflammation of the gums and jawbone caused by different bacteria, but also…

vitellogenin is the carrier of immune elictors⁴. She and her team used honey bee model system, and demonstrated with microscopy and western blotting that vitellogenin binds to bacteria, in Paenibacillus larve, which is the gram positive bacteria found in foulbrood disease, and also Escherichia coli, which is the negative bacteria. Her and her team then validated that vitellogenin binds to pathogen-associated molecular patterns, such as zymosan, lipopolysaccharide, and peptidoglycan, using…

disease was previously thought to be caused by pathogenic bacteria. Adolph Meyer demonstrated in 1886, that this disease could transfer from an unhealthy plant to an healthy plant in the form of liquid plant extract. But in 1892, Dmitri Ivanovski used a ceramic filter that could remove bacteria from the extract and saw that the disease transfer from one plant to another was still possible. That’s when they realized that it wasn’t the bacteria, but rather these other infectious entities that were…

Streptococcus is a type of bacterium which causes the disease. Strangles got its name because historically, affected horses were sometimes suffocated from inflamed lymph nodes in their upper airway and trachea.When a horse gets this disease the bacteria cells attach to the tonsil and lymph nodes and then release enzymes and toxins that damage cells nearby and cause inflammation. Strangles is transmitted by direct contact with an infected horse or sub-clinical shedders. It is also transmitted…

The ways in which bacteria can become resistant to antibiotics and how this contributes to the global healthcare concern of Antimicrobial Resistance (AMR). Antimicrobial resistance is a prevailing issue since the discovery of the first antibiotic Penicillin in 1928. There are 5 mechanisms which allow resistance to impede new antibiotic development for the last 29 years (WHO, 2016) consisting of mutations in target genes, enzymatic resistance, latency, antibiotic efflux and non-specific mutations…

so you yell 5-second rule. Saying that makes it “okay” to eat it. But is it really okay, think about all of the bacteria getting on it. Does picking it up within five seconds really make a difference? Is it really as safe as we make it seem? According to prevention there are a few things to be concerned about when eating food off the ground. For one you could get sick if enough bacteria gets transferred on it. Or you can catch a serious bug like Salmonella or E. coli. The best thing to do would…

higher percentage of bacteria-killing chemicals. Theory: E.Coli is a gram-negative rod-shaped bacterium that commonly inhabits the lower intestines of warm blooded animals. E.Coli is important in the body because it helps synthesize vitamin K, which is vital to blood clotting, and prevents the colonization of pathogenic bacteria in the intestines. E.Coli reproduces using binary fission, a process that creates two identical daughter cells. Binary fission means that the bacteria reproduce by…

infected root canal system Historically, the most wide-spread method for detecting and characterizing bacteria has been by culturing. Culturing bacteria allows the analysis of their morphology, virulence, gram-staining pattern, the quantization of viable microorganisms, as well as the testing of their susceptibility to antibiotics. Consequently, this method may not allow normally viable bacteria to cultivate as the selected culturing media may not have the nutritional and physiologic…

discovered that flies carry more diseases than suspected. The Bristles in a fly’s body attracts the bacteria from where the flies have been. Flies are able to spread bacteria from place-to-place on their legs, feet, and its wings, experiments have shown. In fact, researchers have discovered that for every step taken with a fly it can transfer live bacteria from place-to-place. Many of the bacteria that flies carry are linked with human infections, which includes the stomach bug, blood poisoning,…

Impact of penicillin, novobiocin, and kanamycin on Staphylococcus aureus bacterial growth Introduction: In today’s world, bacteria are becoming more abundant and strong in terms of their resistance to antibiotics. As a result of increasing prescription potency, clinicians are supposed to be conscious of those patients who are more inclined to infection by prescribing the appropriate antibiotics on the basis of their sensitivities along with their cultures (Fleming et al., 2006). A recent case…
