Hepatocystis Vassali
''Hepatocystis vassali'' is a species of parasitic protozoa that infect mammals. Taxonomy The parasite was first described by Laveran in 1905. Hosts The only known host is the red-bellied squirrel (''Callosciurus flavimanus Pallas's squirrel (''Callosciurus erythraeus''), also known as the red-bellied tree squirrel, is a species of squirrel native to Greater China, India, and Southeast Asia.

Laveran
Charles Louis Alphonse Laveran (18 June 1845 – 18 May 1922) was a French physician who won the Nobel Prize in Physiology or Medicine in 1907 for his discoveries of parasitic protozoans as causative agents of infectious diseases such as malaria and trypanosomiasis. Following his father, Louis Théodore Laveran, he took up military medicine as his profession. He obtained his medical degree from University of Strasbourg in 1867. At the outbreak of the Franco-Prussian War in 1870, he joined the French Army. At the age of 29 he became Chair of Military Diseases and Epidemics at the École de Val-de-Grâce. At the end of his tenure in 1878 he worked in Algeria, where he made his major achievements. He discovered that the protozoan parasite ''Plasmodium'' was responsible for malaria, and that ''Trypanosoma'' caused trypanosomiasis or African sleeping sickness. In 1894 he returned to France to serve in various military health services. In 1896 he joined Pasteur Institute as Chief of t ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Pallas's Squirrel
Pallas's squirrel (''Callosciurus erythraeus''), also known as the red-bellied tree squirrel, is a species of squirrel native to Greater China, India, and Southeast Asia. Description Pallas's squirrel is a medium-sized tree squirrel, with a head-body length of , and a tail in length. Both sexes are of similar size and appearance, and weigh between . The colour of the pelt varies considerably between the many different subspecies, but is generally brownish on the upper body with a more reddish tint on the belly, and often with some black on the tail. The precise pattern and shades of the fur are often used to distinguish subspecies from one another, but make it difficult to distinguish the species as a whole from other, similarly variable, tree squirrel species. Subspecies Over 30 subspecies have been identified, although not all are recognised by all authorities: * ''C. e. erythraeus'' * ''C. e. atrodorsalis'' * ''C. e. bartoni'' * ''C. e. bhutanensis'' * ''C. e. bonho ...

Parasites Of Rodents
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

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 ...
