Molecular characteristics of fowl adenovirus strains detected in broiler chickens on diets without immunostimulant supplements.

Introduction: Outbreaks of fowl adenovirus (FAdV) infection in chicken flocks in Poland threaten birds' health and lives and are rising in frequency. The risk of these infections in immunocompromised poultry flocks with developed clinical symptoms was analysed through virus detection in broiler chicks and correlation of cases with the birds' immune strength.

Material And Methods: Samples were analysed from four broiler farms with chicks from the same hatchery in Silesia, Poland where feeding regimes were different.

Antibiotic resistance of biovar isolates from chickens.

Introduction: is an opportunistic bacteria inducing a range of clinical signs in poultry. strains show multidrug resistance to antibacterial substances. The purpose of this study was to examine the susceptibility of biovar isolates collected from the respiratory, reproduction and gastrointestinal tracts of chickens to different antibiotics from various classes.

Probiotic supplementation as an alternative to antibiotics in broiler chickens.

Introduction: The broiler chicken digestive tract microbiome maintains the bird's immunity. Its composition has been shown to be important not only for the immune system but also for the gastrointestinal function and productivity of broiler chickens. If the microbiome is populated by supplementation with and spp.

and in Turkeys in Poland.

The pathogenic mycoplasmas are among the bacteria causing significant losses in the poultry industry worldwide. (MG) and (MS) are economically important pathogens causing chronic respiratory disease, decreased growth, egg production and hatchability rates, and significant downgrading of carcasses. Effective diagnosis of infection with these species in poultry is highly requisite considering their two routes of spreading-horizontal and vertical.

Prevalence, Identification and Antibiotic Resistance of Isolates from Chickens in Poland.

The Gram-negative bacterium is part of the normal avian respiratory, intestinal and reproductive tract microflora and can be transmitted horizontally and vertically. With the coexistence of other relevant factors, becomes an opportunistic pathogen, economically damaging to the poultry industry. This bacterium's prevalence and molecular epidemiology were investigated, and the antimicrobial treatment options for infection in chicken flocks in Poland were assessed.
