Hemolysis

When it derives to contemplating out an unknown bacterial species the whole purpose is to benefit us in order to better understand what this species is capable of. Throughout a general basis of identifying an unknown species we must figure out either it will become a gram-positive or gram-negative type of bacteria and in doing so we must do a gram staining method. This method works because it will direct us to what test we can do next based off either it is negative or positive bacteria, which…

Gram staining was used to distinguish the unknown microbes between gram-positive microbes from gram-negative microbes. Gram-positive microbes contain a thick peptidoglycan with only one outer cell membrane, thus dying the microbes dark purple. Gram-negative microbes contain a thin peptidoglycan with an outer and inner cell membrane, dying the microbes pink when a gram stain test is done. Microbes A and C were gram- positive because of purple dye seen under the microscope. Microbe B was a…

Preeclampsia and eclampsia were first documented by Hippocrates around 400 BC. He believed that a headache associated with a seizure in pregnancy was considered bad. This was the first documented case where it was considered to be a complication to a mother’s pregnancy. Early treatment for Preeclampsia and eclampsia was to bring the body’s fluid status back to normal. They tried to achieve this through altered diets, purging and blood-letting. It was not until 1739 that doctors and…

There have been discoveries of haplotypes for distinct region specific mutations of the HbS genes. The four African Haplotypes include the Senegal, Benin, Bantu, and Cameroon haplotypes. There has also been one discovery of an Asian haplotype referred to as the Arab-Indian haplotype [1]. The occurrence of these haplotypes indicates that the increase in sickle cell anemia is related to the incidence of malaria in the surrounding regions [8]. Evidence that supports the link between the…

I. INTRODUTION The worldwide the bacterial community includes billions of microorganisms. Microbiologist and other scientists are constantly working of identifying species and classifying them by morphological, biochemical and molecular tests. This is valuable to the medical community, as some of these microorganisms are pathogens, but also to other industries such as pharmaceuticals, foods and drinks production, ecological, agriculture and biotechnology as humans have used bacteria for years…

and cough. Long term( chronic exposure): • Hemolytic anemia due to destruction of RBCs. Formation of the Heinz bodies is induced by aniline. Persons with deficiency in the glucose-6-phosphate dehydrogenase are more susceptible to the risk of hemolysis induced by aniline. •…

When aseptically plated on the differential blood agar plate and compared to controls, Unknown 15 was identified as non-hemolytic (gamma hemolysis). Growth best resembled the control Staphylococcus epidermidis which is non-hemolytic, indicating that Unknown 15 did not produce hemolysins to lyse RBCs into hemoglobin (1). Therefore, the alpha and beta hemolytic genus Streptococcus was eliminated…

Clostridium perfringens is typically found in soil and if this is eaten or coming in contact with the animal it can cause variety of diseases, especially in domestic animals. These diseases include different enteric syndromes such as bovine and ovine enterotoxemia, fowl necrotic enteritis, and lamb dysentery. Strains of most toxin types like alpha and beta toxin have been involved in necrotic enteritis beta toxin is caused by type-C strains. The pulpy kidney disease is caused by type-D strains…

positive catalase test removed Lactobacillus species as a possibility. A negative nitrate test removed mycobacterium species as a possibility. And, a positive phenol red arabinose test removed Kurthia species as a possibility. A Blood agar ( Beta hemolysis) test was resulted as negative which left only Listeria Monocytogenes. With performing the series of test I was able to come to the conclusion that my unknown is Listeria Monocytogenes. This microorganism causes listeriosis when someone…

colonies that are slightly raised or flat with irregular margins (Dworkin et al., 2006). On MacConkey’s agar, E. aerogenes will grow, as it is gram negative, and will appear pink as it can metabolize lactose; in blood agar it will grow using gamma hemolysis, causing no change to its color or lysing the blood cells on the plate (Bergey et al., 1957). E. aerogenes can grow in both glucose minimal media and Simmons citrate agar, showing that it can use glucose and citrate, respectively, as its only…
