plasmodium minasense plasmodium minasense plasmodium minasense is a parasite of the genus plasmodium subgenus carinamoeba. plasmodium minasense scientific classification domain: eukaryota clade: diaphoretickes clade: tsar clade: sar clade: alveolata phylum: apicomplexa class: aconoidasida order: haemospororida family: plasmodiidae genus: plasmodium species: p. minasense binomial name plasmodium minasensecarini and rudolphi, 1912 like all plasmodium species p. minasense has both vertebrate and insect hosts. the vertebrate hosts for this parasite are lizards. taxonomy the original description of this species was by carini and rudolphi in 1912 in a lizard mabuia agilis. since then a number of subspecies of p. minasense have been described. the diagnostic features of p. minasense are: the schizonts are smaller than normal erythrocyte nuclei. schzonts produce 4-8 merozoites the gametocytes are equal to or smaller than erythrocyte nuclei in size and round in shape they infect hosts of the lizard families scincidae, iguanidae and teiidae in the neotropics it is currently thought that p. minasense is closely related to plasmodium floridense and plasmodium tropiduri. like much of the taxonomy in this genus this opinion may need to be revised once the species have been subjected to dna analysis. subspecies subspecies are currently named on the basis of the hosts infected. this criterion may be subject to revision when dna based taxonomy is applied to this species complex. the subspecies currently recognised include: p. minasense anolisi p. minasense calcaratae p. minasense capitoi p. minasense carinii p. minasense diminutivum p. minasense minasense p. minasense plicae p. minasense tegui p. minasense anolisi described by telford in 1979 distribution found in panama, central america and the caribbean. hosts known hosts include the lizards anolis cybotes, anolis distichus, anolis frenatus and anolis limifrons p. minasense calcaratae this subspecies was described by telford and telford in 2003. it is characterized by very small, usually fan-shaped, schizonts that average 3.4 × 2.6 micrometres (range: 2.5 – 4.5 × 2.0 – 3.0). the schizonts produce 3.9 (range: 3 – 4) merozoites. the gametocytes are spherical or ovoid averaging 6.7 × 5.0 micrometres (range: 4.5 – 9.0 × 3.0 – 7.0) in size with a length-width product of 33.7 (range: 15 – 54) and a length/width ratio of 1.4 (range: 1.0 – 2.3). by dimension they are not sexual dimorphic. distribution found in venezuela, south america. hosts the only known host is the lizard kentropyx calcarata p. minasense capitoi this subspecies was described by telford in 1979. distribution found in panama, central america. hosts the only known host is the lizard anolis capito p. minasense carinii this subspecies was described by leger and mouzels in 1917 distribution found in coastal south america. hosts the only known host is the lizard iguana iguana p. minasense diminutivum this subspecies was described by telford in 1973 distribution found in panama, central america. hosts the only known host is the lizard ameiva ameiva p. minasense minasense this is recognised as the type species. it was described by carini and rudolphi in 1912 in a lizard mabuya agilis. distribution found in brazil, central america. hosts known hosts include the lizards mabuya agilis and mabuya mabouya. p. minasense plicae this subspecies was described by telford in 1979. distribution found in guyana, south america. hosts the only known host is the lizard plica umbra distribution found in venezuela, south america. hosts the only known host is the lizard tupinambis teguixin
