Talk:Apicomplexa

Apical complex / Apicoplast

The first sentence might mislead to the conclusion that the apical complex is the same as the apicoplast. This should be clarified.--131.152.195.24 (talk) 15:33, 26 February 2009 (UTC)

Number of Species

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.

Motility

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.

Cryptosporidium

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

Blastocystea

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)

Title

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)

Taxonomy

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!

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

Taxonomy

"The phylum is currently divided into four subclasses:"

• Adeleida
• Coccidea
• Gregarinea
• Haemosporidia
• Perkinsea

Taxobox:

• "subdivision_ranks = Classes & Subclasses"
• "subdivision ="
• Aconoidasida
  
  • Haemosporasina
  • Piroplasmasina
• Conoidasida
  
  • Coccidiasina
  • Gregarinasina

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)
