Disseminated infection due to Exophiala pisciphila in Cardinal tetra, Paracheirodon axelrodi
Journal of Fish Diseases, 2016AbstractCardinal tetra, Paracheirodon axelrodi (Schultz, 1956), kept in an ornamental tank, was found to be affected by severe invasive mycosis. Externally, the disease manifested as abdominal swelling, and internally, the anterior part of the intestine was extremely bloated with abundant dematiaceous septate hyphae and an accumulation of fluid ...

The genus Dermocystidium comprises fungal pathogens of the order Dermocystida in the class Ichthyosporea (http://www.ncbi.nlm.nih.gov/taxonomy). Several different Dermocystidium species have been described, infecting a variety of fish hosts and producing gill infections, skin lesions and visceral disease all over the world (Wildgoose 1995; Pekkarinen &

Parasitology Research, 2016
An investigation of mortalities in a group of cardinal tetras Paracheirodon axelrodi Meyers, 1936, a popular ornamental fish, revealed myxozoan parasites in ventricles of the brains in 3/10 fish and the ocular retina of a fourth. Parasite impacts were unclear, as additional histopathological findings were present, including bacterial dermatitis and ...

Temperature is the main factor affecting the distribution of the sympatric Amazon fishes Paracheirodon axelrodi and Paracheirodon simulans. Both species are associated with flooded areas of the Negro river basin; P. axelrodi inhabits waters that do not exceed 30°C, and P. simulans lives at temperatures that can surpass 35°C.

The cardinal tetra (Paracheirodon axelrodi) is the most abundant species of the Brazilian ornamental fish trade, constituting more than 80% of the ornamental fish collected in the middle Negro River basin. Stable isotope analyses were used to identify the autotrophic carbon sources and trophic position for the cardinal in relation to the plant groups ...

Autapomorphies of Paracheirodon axelrodi: 1. Form of mesethmoid spine (27): (0> 1) relatively short, with premaxillae articulating with each other anterior to mesethmoid. Paralleled in nodes 225 and 234 and in Chalceus macrolepidotus. 2. Number of rows of premaxillary teeth (122): (1> 0) one.

Here, a combination of a DNA screening technique, direct sequencing and cloning was used to carry out a large‐scale assessment of intron variability in cardinal tetras – the first to be conducted for an Amazonian forest fish. To the best of the authors’ knowledge, the levels of DNA variability reported in this study are the highest ever documented for ...

Aquatic Toxicology, 2016
Copper at high concentrations is an ionoregulatory toxicant in fish and its toxicity is known to be strongly modulated by the water chemistry. The toxicity of Cu to the tropical fish cardinal tetra (Paracheirodon axelrodi) was investigated in waters from two major rivers of the Amazon watershed: the Rio Negro (filtered

Epidermal club cells (ECCs) are present in many species of teleost fish. In an attempt to justify their presence in the epidermis of fish, they have been associated with numerous functions. One proposed function is communication with conspecifics during a predation event, as these cells may passively release substances upon rupture, which may occur ...

AbstractThe cardinal tetra Paracheirodon axelrodi is a very popular aquarium fish and the most important ornamental fishery resource for riverine communities inhabiting the Rio Negro floodplain in central Amazonia. Here we describe the isolation and characterization of 14 microsatellite DNA loci for cardinal tetras. Number of alleles and heterozygosity
