RECENT NEWS ABOUT FREE-LIVING AMOEBAE

JULY 2021 – TABLES UPDATED

JANUARY 2019 – HAPPY NEW YEARS – ALMOST ALL TABLES AND FIGURES CONCERNING ACANTHAMOEBA, PROTACANTHAMOEBA AND VERMAMOEBA HAVE BEEN UPDATED TO THE END OF 2018.

JANUARY 2019 – A recent paper (Kialashaki et al., Annals of Parasitology 2018, 64(4), 285–297) presents an interesting metanalysis of the occurrence of Acanthamoeba in environmental soil and water samples throughout Iran. 

September 2018 – WE HAVE BEGUN PLACING THE ABSTRACTS FROM PAST FLAM MEETINGS ON OUR SITE.  ABSTRACTS FROM FIVE PREVIOUS FLAM MEETINGS ARE ALREADY ACCESSIBLE. 

August 2018 –  JUST RETURNED FROM A VERY SUCCESSFUL TRIP TO THE INTERNATIONAL CONGRESS OF PARASITOLOGY IN DAEGU, KOREA, WHERE WE HELD SEVERAL SESSIONS EXPLORING ISSUES WITH FREE-LIVING AMOEBAE.  Keynote addresses presented by Ho Joon Shin, Navid Khan and Paul Fuerst.  Sessions chaired by Jacob Lorenzo Morales and Julia Walochnik.

JANUARY 2018 – HAPPY NEW YEARS – ALMOST ALL TABLES AND FIGURES CONCERNING ACANTHAMOEBA, PROTACANTHAMOEBA AND VERMAMOEBA HAVE BEEN UPDATED TO THE END OF 2017.

IN DECEMBER 2017  THE NUMBER OF 18S rRNA GENE SEQUENCES EXCEEDED 4300 IN THE DNA DATABASES.  MOST CHARTS AND TABLES HAVE BEEN UPDATED THROUGH THE END OF 2017.   (click here to see a list of updates to the site)

NOVEMBER 2017 –  THE SOURCE OF THE T99 CLADE IS IDENTIFIED.  THE T99 SEQUENCES ARE ARTIFACTS CAUSED BY CHIMERIZATION OF 18S rRNA PRODUCTS COLLECTED DURING ENVIRONMENTAL DNA STUDIES.  THEY REPRESENT T13 CLADE ACANTHAMOEBA. ANOTHER VERY SIGNIFICANT CONTRIBUTION FROM THE CORSARO LAB (Corsaro et al. 2017b – Parasitology Research)

OCTOBER 2017 – THE NUMBER OF DIFFERENT IDENTIFIABLE T4 ALLELES THAT OCCUR MORE THAN A SINGLE TIME IN THE DNA DATABASES HAS PASSED 100.

APRIL 2017 – FULL LENGTH SEQUENCES OF 18S rRNA GENE FROM A. JACOBSI – A SIGNIFICANT CONTRIBUTION (Corsaro et al. 2017- Parasitology Research 116: 1273).

ANOTHER SIGNIFICANT ADDITION WAS THE APPEARANCE OF TWO NEW GENOME SEQUENCES FROM ACANTHAMOEBA (A. COMANDONI PB30/40 AND A. LENTICULATA  STRAIN 72/2), BOTH DEPOSITED AS SEQUENCE READ ARCHIVES (SRA) FROM THE AUSTRIAN INSTITUTE OF TECHNOLOGY (JANUARY 2017).  INFORMATION IN OUR GENOMES SECTION.

LATE IN DECEMBER 2016, A PAPER APPEARED THAT REINTERPRETS THE EXTENT OF THE ACANTHAMOEBIDAE (Tice, et al. – Biology Direct [2016 Dec 28] 11(1):69.).  SEE THE SECTION BELOW FOR MORE INFORMATION, INCLUDING THE PROPOSAL OF A NEW SEQUENCE TYPE (HERE DESIGNATED T22, REPRESENTED BY THE PROPOSED SPECIES ACANTHAMOEBA PYRIFORMIS).  THE EXPRESSED PORTIONS OF THE GENOME OF A. PYRIFORMIS ARE AVAILABLE ON GENBANK AS A SEQUENCE READ ARCHIVE (SRA).

NOVEMBER 2016 – WE HAVE RECENTLY STARTED A NEW PAGE (“UNANSWERED QUESTIONS“) WHICH LISTS SOME QUESTIONS THAT HAVE ARISEN FROM THE DATA, AND THAT MAY BE OF INTEREST TO ALL RESEARCHERS OF ACANTHAMOEBA
