Assessing the efficacy and zootechnical performance in laying hens after administration of a 1% aqueous solution of fluralaner (Exzolt) for treating natural infestation by Menacanthus cornutus.

A brood of laying hens infested with the lice Menacanthus cornutus (Phthiraptera: Menoponidae) evidenced itching, irritation, and damage to their zootechnical performance. A study was conducted to evaluate the zootechnical performance and infestation control using a 1% solution of fluralaner in a brood of white laying hens infested naturally with lice. The experiment was carried out using 10,560 naturally infested chickens divided into 2 groups: a treatment group of animals that received a 1% solution of fluralaner in drinking water, at a dose of 0.

Prevalence and distribution of pathogenic genes in Campylobacter jejuni isolated from poultry and human sources.

Introduction: Campylobacter jejuni is one of the most common bacterial causes of human gastroenteritis. Despite its public health importance, the virulence factors and mechanisms underlying C. jejuni pathogenesis remain poorly understood and the relationships between these genes and the sources of the strains are not clear.

Efficacy of fluralaner (Exzolt) for the treatment of natural Allopsoroptoides galli infestations in laying hens.

Mite infestations in laying hens can cause losses to producers due to stress, reduced egg production and even death of birds. A new species of mite, Allopsoroptoides galli (A. galli), Analgoidea: Psoroptoididae, was recently identified in commercial laying farms in Brazil, causing damage due to its highly aggressive infestation that results in a sharp drop in egg production and culling.

Comparison of transport crates contamination with Campylobacter spp. before and after the cleaning and disinfection procedure in broiler slaughterhouses.

Campylobacteriosis is one of the most common types of bacterial gastroenteritis affecting humans, and poultry is considered a major source of the causative organism, Campylobacter spp. Broilers may arrive contaminated at slaughterhouses, and transport crates could be considered a potential source of contamination. Thus, cleaning and disinfection procedures are crucial to avoid cross-contamination among flocks.

Detection and Quantification of in Poultry Slaughterhouses Using Conventional Microbiological Technique, Most Probable Number, and Real-Time PCR.

Campylobacteriosis is one of the most common bacteria causing human gastroenteritis. Poultry is a major reservoir of spp. as well as the main source of transmission.
