Abstract Lameness in poultry is a significant issue modern meat production that adversely affects both animal welfare and economic outcomes due to poor leg health, reduced locomotor function, increased feed conversion ratios, performance. Fast-growing broilers are particularly susceptible lameness, with Staphylococcus being major bacterial cause of skeletal infections. The aim this study was identify species isolated from lesions broiler chickens characterize the factors facilitate such...

Abstract Introduction Although the presence of rotaviruses in pigeon samples has been reported since 1980s, its importance as an aetiological agent “classical” young disease (YPD) was not proven until 2020, when Henle–Koch postulates were confirmed for pigeon-type rotavirus A (RVA) genotype G18P(17). Material and Methods From 2011 to archived liver from 117 pigeons submitted by 74 individual lofts tested RVA using a VP6-specific RT-qPCR test. For four positive racing pigeons, more detailed...

Pigeons are widespread bird species in urban regions ( Columba livia forma urbana ) and may carry pathogens with zoonotic potential. In recent years, more data indicate that these multidrug resistant. Our results confirmed global trend. Three different multidrug-resistant were isolated from an oral cavity of a racing pigeon lesions typical for pox virus infection. Staphylococcus aureus was recognized as methicillin resistant, thus resistant to all beta-lactams. Additionally, it also many...

Mycobacteriosis caused by Mycobacterium avium subsp. was observed in a parental loft of 70 meat-breed pigeons. It decided to undertake treatment as the birds represented substantial value owner. A multiagent therapy using azithromycin, marbofloxacin, and ethambutol administered. After 4 mo therapy, desired results were not obtained. At end treatment, poor general condition, with white blood cells above 20 g/L, after clutching, 2-yr-old older euthanatized. Overall, postmortem lesions found 17...

Abstract The primary aim of poultry production is to obtain a high yield and quality end product. To reduce the risk disease, many direct-fed microbial products have been developed. That appears be an excellent tool for disease prevention. We evaluated influence commercial, competitive exclusion (CE) product, Broilact®, on growth rate, hematology, serum biochemistry, innate immunity in male ROSS-308 chickens, randomly divided into two groups (Broilact® treatment control) raised 42 days....

Abstract Background Pigeon Rotavirus A (RVA) infection has been confirmed in pigeons the last decade as a cause of Young Disease (YPD). Although YPD known for many years to date, no studies have conducted track spread RVA during racing season. The presented research aims determine course flights young summer season, one districts Mazovian Voivodeship Poland. Results Faecal samples collected from transport baskets vehicles transporting starting point were tested. quantitative RT-PCR (qRT-PCR)...

Mycobacteriosis is a significant disease of companion and wild birds which causes emaciation widely distributed lesions, as well being potential zoonosis. Its primary aetiological agents in are Mycobacterium avium subsp. the fastidious genavense. This study monitored therapy naturally infected with genavense to gain understanding its effectiveness interrelation co-infections course pharmacotherapy.Five Atlantic canaries (Serinus canaria) one Bengalese finch (Lonchura striata) tentative...
