Evolution of Sickle Cell Sickle Cell was discovered in the United states although it originated in Africa . The sickle cell disease (SCD) describes traits of an inherited red blood cell disorder‚ having SCD means you have abnormal hemoglobin‚ called hemoglobin S or sickle hemoglobin‚ in your red blood cells. What is hemoglobin u might ask?! Well Hemoglobin is a protein in red blood cells that is suppose to carry oxygen throughout the body. But when a sickle cell trait is “Inherited” it could

MALARIA SURVEILLANCE Malaria is Malaria Is caused by infection with a single-celled nucleated protozoan of the genus Plasmodium. There are four species of Plasmodium that cause disease in humans: P. Vivax P. falciparum P. ovale P. malariae P. vivax and P. falciparum are the most prevalent‚ accounting for almost 90 percent of all cases worldwide. Malaria life-cycle Anopheles mosquito goes through asexual and sexual reproduction Asexual reproduction occurs in the human body and sexual reproduction

infection by the Parasite Plasmodium and more than 1 million deaths are recorded annually (World Health Organization‚ Para 5). Malaria is caused by apicomplexan parasites of the genus Plasmodium. Charles Louis Alponse Lavern‚ who was a French army surgeon stationed in Algeria‚ Africa‚ was the first to notice the parasites in the blood of a patient suffering from malaria. The four species that infect humans are Plasmodium vivax‚ Plasmodium falciparum‚ Plasmodium malariae‚ and Plasmodium ovale (Medical Microbiology

6PROTOZOA INTRODUCTION Parasitism A specific type of interaction between two organisms Host-parasite interactions often operate over a longer timescale than those seen with other pathogens Results in significant host-parasite interaction at the cellular and organismal level E.g. Parasites that alter the behavior of the host Giardia lamblia – induce biochemical change in the host cells at the site of infection (duodenal epithelium) Parasites – have life cycles that often involve several hosts (survival

BS801 Genes R Us Questions for study: 1. What functions do transcription and translation carry out‚ and where are they carried out in the cell? Transcription: process of creating an equivalent RNA copy of a sequence of DNA Transcription is the first step leading to gene expression. The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. Occurs in nucleus of the cell Translation: Translation is the production of proteins by decoding mRNA produced

Malaria (also called biduoterian fever‚ blackwater fever‚ falciparum malaria‚ plasmodium‚ Quartan malaria‚ and tertian malaria) is one of the most infectious and most common diseases in the world. This serious‚ sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year‚ five hundred million adults and children (around nine percent of the

we must educate as future nurses to those countries that lack knowledge and have little or no access to healthcare‚ because even these people can contribute to malaria worldwide. There are five species of parasites‚ which infect humans such as Plasmodium falciparum‚ P. vivas‚ P.ovale‚ P.malariae and P.knowlesi. All of these parasites are introduced into our red blood cells by a single bite of the mosquito. The mosquito then injects sporozoites‚ which are immature forms of the parasite into the bloodstream

Malaria contributes very significantly to maternal and fetal mortality - with at least 10‚000 maternal deaths per annum attributable in sub-Saharan Africa. The presentation include headache‚ fever‚ shivering‚ joint pain‚ vomiting‚ hemolytic anemia

million children under the age of fourteen die each year from Malaria. From these figures it is easy to see that eradication of this disease is of the utmost importance. The disease is caused by one of four species of Plasmodium These four are P. falciparium‚ P .malariae‚ P .vivax and P .ovale. Malaria does not only effect humans‚ but can also infect a variety of hosts ranging from reptiles to monkeys. It is therefore necessary to look at all the aspects in order to assess the possibility of a vaccine
