Apical complex / Apicoplast[edit]

The first sentence might mislead to the conclusion that the apical complex is the same as the apicoplast. This should be clarified.-- (talk) 15:33, 26 February 2009 (UTC)

Number of Species[edit]

This page should say how many species are found in the phylum. --Savant13 20:03, 21 December 2006 (UTC)

The short answer is we dont know. The best estimates that I know of suggest > 5000 species. DrMicro.


The article deceptively suggests that Apicomplexa is nonmotile, which is untrue...most are motile...Anyone up for changing it?...If not I'll pull out a few papers to refresh my memory when I have time Jarwulf 05:56, 1 Apr 2005 (UTC)

Based on this glossary entry, I'd say nonmotility is definitive...? --Renice 19:37, 4 October 2006 (UTC)

apicomplexan: A sporozoan protist that lacks special locomotor organelles but has an apical complex and a spore-forming stage. It is either an intra- or extracellular parasite of animals; a member of the phylum Apicomplexa.

Ah, but this suggests otherwise. --Renice 19:52, 4 October 2006 (UTC)

Rhoptries: The osmiophilic rhoptries – as well as the micronemes – are characteristic cytoplasmic inclusions of the motile stages of sporozoans.


For the record, the sources I'm finding say Cryptosporidium is a coccidia; for example, see:


Are Blastocystea Apicomplexa or Chromista? --Kupirijo 10:00, 1 January 2007 (UTC)

Stramenopile, it seems pretty clear from the refs at Blastocystis (Chromista doesn't seem to be monophyletic, so I wouldn't use that term, per refs at Chromalveolate). If anyone knows of something we are missing, please provide specifics. I've updated this article accordingly. Kingdon (talk) 02:45, 12 January 2009 (UTC)


This page should be moved to Sporozoan. --Aruseusu (talk) 16:05, 31 May 2009 (UTC)

Apicomplexa seems to be a much more common term these days (I tried a google scholar search). Unless there is something I'm missing, it looks like a case where wikipedia needs to follow existing usage. Kingdon (talk) 19:12, 1 June 2009 (UTC)


This area is a mess. I am finding multiple contradictory references on this. I am working to resolve this. DrMicro (talk) 21:20, 27 November 2010 (UTC)

Subclasses taxonomy - mess, this entire article needs in-line citations![edit]

This article had a subclasses section that says there are four, and the taxobox is divided into different classes and subclasses.


"The phylum is currently divided into four subclasses:"


I've removed the taxonomy section, but left the taxobox, until it is corrected. Both should also have citations attached before replacing anything. --Kleopatra (talk) 18:54, 28 November 2010 (UTC)
