🧪 New work on the thorny-headed worm Rhadinorhynchus cololabis shows two spine morphotypes are actually one species (ASAP + BI data).
Results also question several Rhadinorhynchus taxa.
First complete mitogenome of R. cololabis reported.

New insights into why tap water might be a major risk factor for Acanthamoeba keratitis.

doi.org/10.1051/para...

Calcium ions in regular tap water dramatically increase Acanthamoeba castellanii adhesion (up to 80% more than in purified water) and enhance its cytopathic effects.

Using immunoproteomics and LC-MS/MS, we identify proteins linked to the diagnostic IgM triplet—key to understanding vertical transmission and new therapeutic avenues.
doi.org/10.1051/para...
2D immunoblot of T. gondii RH strain proteins. A and B. Obtained after incubation with two NNTPos sera (patients 5BB (A) and 8BB (B)) and revelation with peroxidase-conjugated goat anti-human IgM antibodies. C and D. Obtained after incubation with two NNTNeg sera (patients 17BB (C) and 19BB (D)) and revelation with peroxidase-conjugated goat anti-human IgM antibodies. These immunoblots reveal the IgM triplet spots of interest (21–24) present only in NNTPos sera and identified by superposition with the protein profile of the T. gondii RH strain (black box). These immunoblots also make it possible to exclude the spots that are not specific to the IgM triplet (25 and 26) present in NNTPos and NNTNeg sera and identified by superposition with the protein profile of the T. gondii RH strain (NNTPos: newborns positive for the IgM triplet; NNTNeg: newborns negative for the IgM triplet).

Laboratory specimens of Pediculus humanus corporis (2) were also used in this study.

𝗛𝗮𝘃𝗶𝗻𝗴 𝘁𝘂𝗿𝗸𝗲𝘆 𝗳𝗼𝗿 𝗧𝗵𝗮𝗻𝗸𝘀𝗴𝗶𝘃𝗶𝗻𝗴?

If you need a conversation starter, why not bring up this 1948 paper on 𝘁𝘂𝗿𝗸𝗲𝘆 𝗽𝗮𝗿𝗮𝘀𝗶𝘁𝗲𝘀! The translation below will guide you through the twists of Cyclocoelum systematics.

Guaranteed to fascinate everyone at the table. 🦃🧪
Paper: doi.org/10.1051/para...
Translation of page 190: It would be quite embarrassing for Mr. Neveu-Lemaire and G. Lesbouyries if one were to ask them who has ever seen a Cyclocoelum in the ceca of a turkey; they simply copied an incorrect piece of information based on a mistaken interpretation of an old text. Here is the origin of the error: in Padua, Ant. Frid. Polonio, having found a trematode in a turkey cecum, gave it to Raf. Molin, who described it very incompletely (1859, p. 824), attributing it to Monostomum attenuatum Rudolphi 1809 [which is actually a Notocotylus]. Despite the inadequacy of Molin’s description, Fra. Sav. Monticelli (1892, p. 709) considered that, by certain characters, it resembled M. mutabile and by others M. flavum, but that since the resemblance seemed greater with M. mutabile, he ventured to suggest the possible identity of the two forms. However, when one refers back to Molin’s text, one reads that it concerns a species with both testes at the same horizontal level and the vitellaria located in the middle third of the body—features that rule out any identification with Cyclocoelum mutabile (Zeder). Nonetheless, Monticelli’s unacceptable and vague supposition unfortunately gained acceptance with Alcide Railliet (Traité de Zoologie médicale et agricole, 1895, p. 338) and was retained by L. G. Neumann (1909, p. 137). In Railliet’s Traité, one finds: “Monostomum attenuatum Molin 1859 nec Rudolphi 1809,” listed as a synonym of Monost. mutabile Zeder! Since Monticelli’s assumption rests on no solid basis, it is desirable that authors of textbooks, manuals, and general works definitively abandon the claim that Cyclocoelum mutabile (Zeder) has been found in the ceca of the turkey.
