The poultry mite, Dermanyssus gallinae, is a parasite of fowl and birds worldwide, causing huge economic losses in production systems. We investigated gene-knockdown approach in identifying potential vaccine antigens, targeting Histamine Releasing Factor (HRF) and Cathepsin D (C), through immersion in dsRNA derived from the two genes, for 7 and 16 h respectively, alongside LacZ control. Quantit...

Dermanyssus gallinae, the poultry red mite, is an obligatory blood-sucking ectoparasite. The genetic diversity of D. gallinae has been examined in some countries, but so far not in Asian countries. Here, we sequenced a part of the mitochondrial cytochrome oxidase subunit I (COI) and16S rRNA genes and nuclear internal transcribed spacers (ITS) region in 239 mite samples collected from 40 prefect...

Contextualización: el ácaro rojo de las aves corral (Dermanyssus gallinae) es un ectopárasito que afecta la salud gallinas ponedoras, genera estrés en población, disminuye tasa crecimiento y por ende baja calidad los huevos. Vacío conocimiento: control D. gallinae se hace a través acaricidas químicos hacia cuales han generado resistencia, necesario nuevas alternativas base productos naturales, ...

SUMMARY Although the poultry red mite Dermanyssus gallinae (De Geer, 1778) is the major parasitic pest in poultry farming causing substantial economic losses every year, nucleotide data are rare in the public databases. Therefore, de novo sequencing covering the transcriptome of D. gallinae was carried out resulting in a dataset of 232 097 singletons and 42 130 contiguous sequences (contigs) wh...

Dermanyssus gallinae (Arthropoda, Mesostigmata) is suspected to be involved in the transmission of a wide variety of pathogens, but nothing is known about its associated non-pathogenic bacterial community. To address this question, we examined the composition of bacterial communities in D. gallinae collected from standard poultry farms in Brittany, France. Genetic fingerprints of bacterial comm...

The bacterium Erysipelothrix rhusiopathiae can infect a wide range of mammals (including humans) and birds. Disease outbreaks (erysipelas) have been considered unusual in chickens internationally, but outbreaks with high mortality and egg production losses have been diagnosed in Swedish laying hen flocks every year since 1998. Different aspects of E. rhusiopathiae infection in chickens were exa...
