Intraspecific Variation in the Characteristics of Cryptocaryon irritans Isolated in Japan

Journal of Fish Diseases, EarlyView.
ABSTRACT Cryptocaryon irritans is an obligate parasitic ciliate and the causative agent of cryptocaryoniasis. This parasite is widely distributed in tropical and subtropical marine waters, and numerous outbreaks in aquaculture have been reported worldwide. Previous studies have documented variations in biological traits, such as cell size, serotype and

Utility of the ITS1 Region for Phylogenetic Analysis in Stingless Bees: a Case Study of the Endangered Melipona yucatanica Camargo, Moure and Roubik (Hymenoptera: Meliponini).

Sociobiology, 2014
The internal transcribed spacers of the ribosomal RNA gene have been recently proposed as an appropriate marker for genetic analysis of the molecular variation of stingless bees.

A comparative study of populations of Ectopleura crocea and Ectopleura ralphi (Hydrozoa, Tubulariidae) from the Southwestern Atlantic Ocean [PDF]

, 2014
Ectopleura crocea (L. Agassiz, 1862) and Ectopleura ralphi (Bale, 1884) are two of the nominal tubulariid species re-corded for the Southwestern Atlantic Ocean (SWAO), presumably with wide but disjunct geographical ranges and similar morphologies.

Gradual processing of the ITS1 from the nucleolus to the cytoplasm during synthesis of the human 18S rRNA

Nucleic Acids Research, 2013
Defects in ribosome biogenesis trigger stress response pathways, which perturb cell proliferation and differentiation in several genetic diseases. In Diamond–Blackfan anemia (DBA), a congenital erythroblastopenia, mutations in ribosomal protein genes ...

Unveiling the phylogenetic position of the type species of the syndinean genus Amoebophrya and broad divergence of the A. ceratii complex

Journal of Phycology, EarlyView.
Abstract The syndinean genus Amoebophrya comprises endoparasitic dinoflagellates that infect various marine protists. Since the description of the type species, A. sticholonchae, a parasite of the radiolarian Sticholonche zanclea, an additional six Amoebophrya species have been formally described.

Diversity analysis of Bemisia tabaci biotypes: RAPD, PCR-RFLP and sequencing of the ITS1 rDNA region

Genetics and Molecular Biology, 2008
The Bemisia tabaci complex is formed by approximately 41 biotypes, two of which (B and BR) occur in Brazil. In this work we aimed at obtaining genetic markers to assess the genetic diversity of the different biotypes.
