Pfeifferinella
genus of protists
Pfeifferinella is a genus of parasitic alveolates in the phylum Apicomplexa. This genus has been poorly studied and little is known about it. Species in this genus infect marine priapulid worms and terrestrial and freshwater gastropods.
History
This genus was described by Wasielewski in 1904.
Taxonomy
The type species is Pfeifferinella ellipsoides.
Six species are currently recognised in this genus.
Description
The majority of species have developmental stages undergo merogony, gamogony and sporogony within the digestive gland of gastropod host. The oocysts are passed in the faeces.
The oocysts lack sporocysts. Each oocyst have 8-14 free sporozoites.
This brief starts where responsible research should: with the source description of “Pfeifferinella” as genus of protists. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of protists. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Dec 8, 2025. The linked authority identifier is Q16987904. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1904.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
