Nycteria Brucechwatti
''Nycteria'' is a genus of protozoan parasites that belong to the phylum Apicomplexa. It is composed of vector-borne haemosporidian parasites that infect a wide range of mammals such as primates, rodents and bats. Its vertebrate hosts are bats. First described by Garnham and Heisch in 1953, ''Nycteria'' is mostly found in bat species where it feeds off the blood of their hosts and causes disease. Within the host, ''Nycteria'' develops into peculiar lobulated schizonts in parenchyma cells of the liver, similarly to the stages of ''Plasmodium falciparum'' in the liver. The vector of Nycteria has been hard to acquire and identify. Because of this, the life cycle of ''Nycteria'' still remains unknown and understudied. It has been suggested that this vector could be an arthropod rather than a mosquito or the vector of most haemosporidian parasites. Etymology The word ''Nycteris'' is derived from the Greek word “nykteros”, also “bat”. ''Nycteris'' is a bat genus in the family ...

Gametocytes
A gametocyte is a eukaryotic germ cell that divides by mitosis into other gametocytes or by meiosis into gametids during gametogenesis. Male gametocytes are called ''spermatocytes'', and female gametocytes are called ''oocytes''. Development The development of gametogonia to primary gametocytes is called gametocytogenesis. The further development of primary gametocytes to secondary gametocytes is a part of gametidogenesis. Gametogenesis is the formation or production of gametes (taking place during meiosis). The development and maturation of sex cells also takes place during meiosis. Gametogenesis is also the process of formation in male and female gametes that occur in the gonads (ovary and testis). Both male and female produce gametes. Male gametocytes are called spermatocytes and female gametocytes are called oocytes. The term gametocyte is also used, for example, when talking about gametocytes of species like ''Plasmodium falciparum'' or ''Plasmodium vivax'', which transmi ...

Haemosporida
The Haemosporida (sometimes called Haemospororida) are an order of intraerythrocytic parasitic alveolates. Taxonomy Over 500 species are in this order, organised into four families: the Garniidae, the Haemoproteidae, the Leucocytozoidae, and the Plasmodiidae. The majority of the species lie within three genera: ''Haemoproteus'', ''Leucocytozoon'', and ''Plasmodium''. The Haemoproteidae and the Plasmodiidae both produce pigment. These families have been placed in the suborder Laveraniina. Neither the Haemoproteidae nor the Leucocytozoidae have an asexual cycle in the peripheral blood. The Garniidae do not produce pigment, but do have an asexual cycle in the blood. The taxa in detail are: *Family Garniidae ** Genus '' Fallisia'' Lainson, Landau & Shaw 1974 *** Subgenus '' Fallisia'' *** Subgenus '' Plasmodioides'' Gabaldon, Ulloa and Zerpa 1985 ** Genus '' Garnia'' Lainson, Landau and Shaw 1971 ** Genus '' Progarnia'' Lainson 1995 *Family Haemoproteidae ** Genus '' Johnsprenti ...

Nycteris Thebaica
The Egyptian slit-faced bat (''Nycteris thebaica'') is a species of slit-faced bat broadly distributed throughout Africa and the Middle East. It is a species of microbat in the family Nycteridae. Six subspecies are known. Description The Egyptian slit-faced bat gets its name from a deep slit that runs from the base of the ears to the nostrils, between the nose leaves. The bats typically weigh , with females weighing up to . The wings are broad, with a wingspan of and a low aspect ratio, allowing for high maneuverability and the ability to hover close to the ground. The dorsal surface is dusky to reddish brown, while the underside is white to whitish gray. This bat has lighter fur than other members of the nycterid family. It has a long tail, reaching to . Distribution and habitat This species is able to thrive in a variety of tropical and temperate habitats throughout Africa and the Arabian peninsula.

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erythrocyte
Red blood cells (RBCs), also referred to as red cells, red blood corpuscles (in humans or other animals not having nucleus in red blood cells), haematids, erythroid cells or erythrocytes (from Greek ''erythros'' for "red" and ''kytos'' for "hollow vessel", with ''-cyte'' translated as "cell" in modern usage), are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O2) to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or in fish the gills, and release it into tissues while squeezing through the body's capillaries. The cytoplasm of a red blood cell is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells and the blood. Each human red blood cell contains approximately 270 million hemoglobin molecules. The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liver
The liver is a major Organ (anatomy), organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the Protein biosynthesis, synthesis of proteins and biochemicals necessary for digestion and growth. In humans, it is located in the quadrant (anatomy), right upper quadrant of the abdomen, below the thoracic diaphragm, diaphragm. Its other roles in metabolism include the regulation of Glycogen, glycogen storage, decomposition of red blood cells, and the production of hormones. The liver is an accessory digestive organ that produces bile, an alkaline fluid containing cholesterol and bile acids, which helps the fatty acid degradation, breakdown of fat. The gallbladder, a small pouch that sits just under the liver, stores bile produced by the liver which is later moved to the small intestine to complete digestion. The liver's highly specialized biological tissue, tissue, consisting mostly of hepatocytes, regulates a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizont
Apicomplexans, a group of intracellular parasites, have life cycle stages that allow them to survive the wide variety of environments they are exposed to during their complex life cycle. Each stage in the life cycle of an apicomplexan organism is typified by a ''cellular variety'' with a distinct morphology and biochemistry. Not all apicomplexa develop all the following cellular varieties and division methods. This presentation is intended as an outline of a hypothetical generalised apicomplexan organism. Methods of asexual replication Apicomplexans (sporozoans) replicate via ways of multiple fission (also known as schizogony). These ways include , and , although the latter is sometimes referred to as schizogony, despite its general meaning. Merogony is an asexually reproductive process of apicomplexa. After infecting a host cell, a trophozoite ( see glossary below) increases in size while repeatedly replicating its nucleus and other organelles. During this process, the orga ...
