The complete mitochondrial genome of Paracheirodon axelrodi (Characiformes:Characidae:Paracheirodon)

Mitochondrial DNA Part A, 2014
The complete mitochondrial genome of Paracheirodon axelrodi was obtained by the traditional polymerase chain reaction method. The mitogenome was determined to be a 17,100 bp long circular molecule. It contains the typical complement of 13 protein-coding genes, 2 rRNAs and 22 tRNAs. This is first report on the complete mitogenome sequence of P. axelrodi.

Disseminated infection due to Exophiala pisciphila in Cardinal tetra, Paracheirodon axelrodi

Journal of Fish Diseases, 2016
AbstractCardinal 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 ...

Cutaneous infection with Dermocystidium salmonis in cardinal tetra, Paracheirodon axelrodi (Schultz, 1956)

Journal of Fish Diseases, 2014
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 &

Extremely high variability in the S72 intron of the Amazonian cardinal tetra (Paracheirodon axelrodi)

Journal of Fish Biology, 2007
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 ...

Autotrophic energy sources for Paracheirodon axelrodi (Osteichthyes, Characidae) in the middle Negro River, Central Amazon, Brazil

Hydrobiologia, 2007
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 ...

Epidermal club cells in the cardinal tetra (Paracheirodon axelrodi): Presence, distribution, and relationship to antipredator behavior

Zoology
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 ...

Microsatellite markers for the cardinal tetra Paracheirodon axelrodi, a commercially important fish from central Amazonia

Molecular Ecology Notes, 2004
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

Mechanisms of Na+ uptake, ammonia excretion, and their potential linkage in native Rio Negro tetras (Paracheirodon axelrodi, Hemigrammus rhodostomus, and Moenkhausia diktyota)

Journal of Comparative Physiology B, 2014
Mechanisms of Na(+) uptake, ammonia excretion, and their potential linkage were investigated in three characids (cardinal, hemigrammus, moenkhausia tetras), using radiotracer flux techniques to study the unidirectional influx (J in), efflux (J out), and net flux rates (J net) of Na(+) and Cl(-), and the net excretion rate of ammonia (J Amm).

Phylogeography of a flooded forest specialist fish from central Amazonia based on intron DNA: the cardinal tetra Paracheirodon axelrodi

Freshwater Biology, 2009
Summary1. Historic and extant landscape structures and environmental conditions are known to influence phylogeographic patterns and population histories in organisms from Amazonia. Recent work suggests that events of the Tertiary Period have played a significant role in generating biodiversity in this exceptionally rich but understudied region. However,
