Introduction Bacterial vaginosis is known to be the most common cause of abnormal vaginal discharge in women of childbearing age (Hay, 2010). Bacterial vaginosis is the result of the substitution of normal vaginal lactobacilli with anaerobic bacteria Gardnerella vaginalis and Prevotella, Peptostreptococcus and Bacteroides spp., which will result loss of the normal vaginal acidity (Turovskiy, Sutyak Noll, & Chikindas, 2010). Bacterial vaginosis is the main trigger of vaginal discharge or malodor in
Bacterial Vaginosis is a common condition. It is the most frequent vaginal complaint in women and young girls age 14 to 44. My research shows that approximately 29% of women in the US are disturbed by bacterial vaginosiis..It is found in about 25% of pregnant women in the US and approximately 60% of women who have an STD. Bacterial vagnios produces a discharge, from an excessive unusual bacteria in the vagina. In the past, the condition was called gardneralla vaginitis, after the bacteria that was

Additional support for this conclusion was obtained in a study of the grivet monkey as a model for bacteria vaginosis. Bacteria vaginosis is treated with antibiotic medications (CDC). Metronidazole is commonly used. Metronidazole treatment does not adversely affect lactobacilli so they are able to recolonize the vagina and reduce the risk of late-stage relapse (Catlin, 1992)

beneficial to both mother and baby and the environment as well. Breastfed children are less likely to have ear infections, allergies, vomiting, pneumonia, urinary tract infections, chronic digestive disease, insulin-dependent diabetes mellitus, bacterial meningitis, research also indicates that breastfeeding may help protect against Sudden Infant Death Syndrome (SIDS), women who were breastfed as infants have a lower rate of breast cancer, and breastfeeding helps promote bonding between mother and
Investigating the Optimum pH Bacterial and Mammalian Amylase Digests Starch Solution [IMAGE] Biology Coursework Monique Noel 12T Finding the Optimum pH Bacterial and Mammalian Amylase Digests Starch Solution. Introduction I am investigating the optimum pH bacterial and mammalian amylase digests starch solution. To do this I will conduct an experiment using bacterial and mammalian amylase, subjecting them to varying pH levels and record at which pH level the enzyme
Bacterial growth is defined as the division of one bacterium, resulting in two identical cells. This process is referred to as the binary fission that doubles the bacteria population. All three cells are identical. The bacteria go through a growth spurt in order for it to survive and grow. In order to show a bacteria growth curve, scientists create a perfect habitat to predict the bacteria’s growth curve. The growth curve gives the scientists an idea of how certain bacteria will act and how
of microbiology lies the bacterial cell, one that differs from those of a plant or animal because it lacks a nucleus and membrane-bound organelles which, in turn are traded for pili, flagella, and in some cases a cell capsule. Bacteria that are capable of causing illness or disease are called pathogens, pathogens work by releasing toxins in the body or directly damaging the host’s cells. An article by Lise Wilkinson explains that the earliest categorizations of bacterial cells first occurred in the
Gram staining is the most essential and all around used staining technique in bacteriology lab. Gram staining was firstly presented by Christian Gram in 1883. This method is utilized to distinguish between gram positive and gram negative bacteria which have consistent differences in their cell wall. Gram positive bacteria stain blue-purple and gram negative bacteria stain pink-red. There are a few objectives as to why we ought to do this experiment; to gain knowledge of the differences between gram
Results Observing under 1000X magnification, the gram stain depicts purple bacilli, as seen in Figure 1. Figure 2 depicts growth of a light brown, opaque bacteria on a Phenylethyl Alcohol Agar (PEA) plate. As seen in Figure 3, the blood agar plate shows brown growth surrounded by a very thin clear area. Figure 4 shows an endospore stain of the gram-positive unknown. It depicts green endospores surrounded by pink bacilli. Figure 5 depicts a slant of gram-positive isolate, which appears as an opaque
INTRODUCTION The purpose of this investigation was to identify an unknown bacterium. “At any time there are millions of bacteria living around, on, or inside us” (The Plague). Bacterium can’t be identified by merely looking at it. Many bacteria have the similar appearances in growth. “In most cases, detection is based on the reaction of an enzyme with a certain substrate” (Sigma-Aldrich). Identification is usually based on the results of the bacterium’s cells metabolic capacities. Some bacteria
Microbial pigments have antioxidant activity because of their biological functions.and these pigments are Carotenoid ,naphthaquinone,and Violacein. Bacterial pigment plays role as antioxidant by inhibiting photodynamic lipid peroxidation in liposome and give protection against photodamage (Rajagopal et al. 1997).Xanthomonadin is example of this bacterial pigment. Yellow pigment from Staphylococcus aureus which is called as staphyloxanthin.it prevents CCl4 induced oxidative stress in swissalbino
The dichotomous keys show process of elimination taking place and several steps that were performed to the two unknown bacteria. Bacteria number one was concluded to be either S. aureus or E. faecals. As shown, a gram stain was performed to bacteria 1, because it helped in separating the bacteria into Gram negative or positive. Bacteria 1 was Gram positive bacteria, so the next step was to eliminate the bacteria that were bacilli, because under the microscope the bacteria was shown to be cocci. Then
Results The unknown bacterium that was handed out by the professor labeled “E19” was an irregular and raised shaped bacteria with a smooth texture and it had a white creamy color. The slant growth pattern was filiform and there was a turbid growth in the broth. After all the tests were complete and the results were compared the unknown bacterium was defined as Shigella sonnei. The results that narrowed it down the most were the gram stain, the lactose fermentation test, the citrate utilization test
In today's medicine, correctly and quickly identifying a patient's illness is essential for proper treatment. In order to execute this, biochemical tests of various magnitudes are used to identify what a patient may be infected with. In our lab, we received an unknown sample of urine. After several biochemical tests, we determined our unknown specimen to be Enterobacter aerogenes. This particular bacterium is gram-negative, with rod shaped morphology. In order to determine whether our specimen
development. It is because penicillin and its derivatives have played such a vital role in everyday medicine that it is such an important topic. Penicillin works by virtue of its beta-lactam ring that specifically binds to microbial enzymes in bacterial cell walls, and keeps the cell membrane structures from linking up. Eventually, if the bacterium keeps dividing, the cell membrane will become increasingly weaker and lyse. The beta-lactam ring is very simple in and of itself, but its ability to
typically when you’re sick, you go to the doctors. If your doctor happens to suspect that you may have an infection, he or she may order to have a culture, and/or a gram stain done to check for bacteria. If it happens to be that you do have a bacterial infection, your doctor can then have a gram stain done on the bacteria to see if the bacteria in your infection are gram negative or gram positive bacteria. A gram stain can be performed on various types
After gram staining, it was revealed that unknown 1 microscopic morphology was Gram positive cocci in clusters Staphylococcus epidermiclis. When observed under the microscope, the bacteria’s morphology displayed a purple color, round shape, and clustered together like bundles of grapes. It was difficult to locate the specimen due to the student’s lack of experience with using the microscope. The student forgot to use the stage clip to hold the slide in place, which made it difficult to control
Metronidazole Article: Bacterial vaginosis is one of the major contributors of vaginal infections during pregnancy and accounts for 40 percent of these cases. Generally, bacterial vaginosis is associated with several obstretic complications like pre-term labor and delivery, untimely rupture of membranes, postpartum endometrisis, and chorioamnionitis (Wang et. al., 2010, p.444). Metronidazole has traditionally been used as the drug of choice in the treatment of bacterial vaginosis because it is an agent
Female genital mutilation is a common practice throughout many parts of the world. FGM is a practice that has been banned in a lot of countries but unfortunately there are still many cultures that practice this act. A considerable amount of people view female genital mutilation as a form of abuse. I disagree with the practice of female genital mutilation. FGM is a procedure that alters the external female genital organs. There are over 100 million girls and women worldwide who are living with the
