Exponential Growth period during Phase A of the given graph. This is visible from the graph because of the distinct J-shaped curve of the graph‚ this indicates that the curve is Exponential. The curve starts with stable phase not seeming to increase because the growth is slow due to the small population known as the Lag Phase. Then the growth build momentum and grows at an accelerating pace until environmental conditions prevent for their growth‚ this is known as the Exponential Growth Phase. To accurately

Cause Bacterial meningitis can become serious even causing death in as little as a couple of hours. Those who are affected by this disease can recover for it. However‚ those who are unfortunate may have permanent disabilities including: hearing loss‚ brain damage‚ learning disabilities‚ etc. caused by the infection. There are a number of bacteria’s that result in meningitis such as: streptococcus pneumoniae‚ group B streptococcus‚ Neisseria meningitides‚ Haemophilus influenza‚ and listeria monocytogenes

Bacterial Vaginosis is a bacterial infection. This STD occurs when there is an overgrowth of bacteria that is normally present in the vagina. BV can only be spread through female sexual interactions. Males are not able to get this STD because they do not have the same bacteria as women. There are rarely ever any extremely noticeable symptoms. Some symptoms of bacterial vaginosis include; abnormal vaginal discharge‚ vaginal itching‚ odor‚ and/or burning when urinating. Since the symptoms can be unnoticeable

of the symptoms. The study of meningitis dates back to the 1960’s when the causative organisms were discovered and treatments were developed. Since then the mortality rate from bacterial meningitis has not changed much despite the introduction of new antibiotics and treatments (Hussein 360). In the case of bacterial meningitis no one casual organism causes all of the cases‚ but rather there are many that capable of causing it. Although there are many causal organisms‚ there are three that are

identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully isolated two different bacterial species by examining my MAC and CNA plates. Only

Many of the bacteria that cause common bacterial infection are mutating and therefore gaining resistance. This means that the original antibiotics that were once used to treat these common illnesses are becoming increasing ineffective. This resistance delays treatment as the original antibiotics are ineffective. This can lead to the disease worsening and even death. This means that common illnesses that were once easily treated by antibiotics are no longer so easy to treat. This results in increased

inhibits the enzyme peptidyl transferase. This inhibition results to the prevention of the transfer of amino acid for growing peptide chains which leads to the inhibition of the formation of bacterial protein. (Michigan State University‚ 2011). Chloramphenicol is a broad-spectrum antibiotic. (Hitner et al.‚ 2016). Bacterial microorganisms become resistant by the inactivation of chloramphenicol through the enzyme acetyltransferases. (Rang et al.‚ 2016). Chloramphenicol resistance are very common in Staphylococcus
