surgical intervention. Mortality from fulminant colitis may reach 50 %. Untreated intestinal Amoebiasis may proceed to chronic colitis presenting with recurring bloody diarrhea and abdominal discomfort. From the intestinal mucosa E. Histolytica trophozoites follow two paths. Some of them develop into cysts and get excreted in the feces to be recycled while others invade the intestinal mucosa and enter the bloodstream. Blood circulation enables the parasite to disseminate, invade and destroy

for a local hospitals or sometimes hand out medication themselves. Laboratories in many developing countries depend on microscopy and culture for the diagnosis of Amoebiasis. However, due to morphological similarities between E. Histolytica and other non-pathogenic Entamoeba types misdiagnoses are likely. Most of the newer more sensitive and specific tests are do not exist in

Medicinal herbs have curative properties due to presence of various complex chemical substance of different composition, which are found as secondary plant metabolites in

Bygraves The word ‘dysentery’ is used to describe two different kinds of stomach illnesses, both of which result in an inflammation of intestines along with very severe and bloody diarrhea. Amoebic Dysentery is caused by an internal protozoan (Entamoeba histolytica) that has two forms: the cyst form is its infective form and is spherical in shape with refractile walls. The other form is the trophozoite form which is it mobile form and has a diameter 15-30 micrometers. According to Medline Plus, about

Mary Gorton Microbiology Research paper Page 1 General defense mechanisms associated with the digestive system The gastrointestinal tract is a lymphoid organ, and the lymphoid tissue within it is collectively referred to as the gut-associated lymphoid tissue or GALT. The number of lymphocytes in the GALT is roughly equivalent to those in the spleen, and, based on location, these cells are distributed in three basic populations: 1. Peyer's Patches: These are lymphoid follicles similar in many

that trogocytosis is a mechanism in which cells receive nutrition from other cells, however, in the transaction parasites and host cells, the parasites virulence is enhanced killing the host cells. In the processes of amoebiasis, ingested E. histolytica settles in the colon of the individual, releases its mucus and interacts with the exposed enterocyte cells lining in colon causing cell death by lysis. Other models suggested that parasite attached themselves to host cells in order to kill through

1. Describe the characteristics of the Retortamonadida and Diplomonadida orders. Both Retortamonadida and Diplomonadida lack mitochondria as well as a Golgi apparatus, which are also known as dictyosomes. Retortamonadida and Diplomonadida also possess a recurrent flagella within a groove and can occupy low oxygen environments. Both orders of Retortamonadida and Diplomonadida are commonly found within humans. 2. Describe the morphology of Chilomastix mesnili trophozoites. In the cyst stage of

Hydrogenosome relationship Under oxygen-restricted conditions, the mitochondrion has undergone reductive alterations of its content and function. These changes were most likely driven by the independence of ATP generation on oxidative phosphorylation in the mitochondria. These reduced mitochondria are called mitochondrion-related organelles (MROs) (9). There are two types which lack mitochondrial DNA--the hydrogenosome and the mitosome. They are distinguished by the fact that the hydrogenosome has

Abstract Premature delivery is a significant cause of child mortality and morbidity worldwide. It is particularly prevalent in the developing world. As HIV is highly prevalent in Tanzania and much of sub-Saharan Africa, it is important to determine risk factors for prematurity among HIV-positive pregnancies. The aims of this study were to identify risk factors of live preterm (<37 completed weeks gestation) and very preterm (<34 completed weeks gestation) birth among a cohort of 927 HIV positive

On admission, the body temperature was 39ºC. Physical examination revealed an ill-appearing well-developed girl with mild pallor, and anicteric sclera. The patient had right upper quadrant abdominal tenderness with no distension or hepatomegaly. Relevant laboratory data included white blood cell count of 13.780/μL with 78% neutrophils; hemoglobin, 10.9 g/dL and C-reactive protein was 325 mg/L. Liver function tests, blood urea nitrogen and electrolytes were within reference ranges. Chest radiograph
