The impact of buckwheat and paulownia (Paulownia elongata × P. fortunei) intercropping on beekeeping value and buckwheat yield.

Increasing crop diversity is a way for agriculture to transition towards a more sustainable and biodiversity-friendly system. Growing buckwheat intercropped with paulownia can contribute not only to mitigating climate change but can also enrich the environment with species of agricultural importance, without causing a decline in pollinators, since buckwheat is pollinated mainly by the honeybee. In a field experiment comparing growing buckwheat with paulownia against a monoculture crop, we investigated differences in flower visitation and beekeeping value, as well as the associated impact on crop yields.

Isolation and Characterization of Phages Active against Causing American Foulbrood in Honeybees in Poland.

The aim of this study was the isolation and characterization, including the phage effect on honeybees in laboratory conditions, of phages active against , the causative agent of American Foulbrood-a highly infective and easily spreading disease occurring in honeybee larva, and subsequently the development of a preparation to prevent and treat this dangerous disease. From the tested material (over 2500 samples) 35 spp. strains were obtained and used to search for phages.

Conjunctival aerobic bacterial flora in healthy Silesian foals and adult horses in Poland.

Background: Commensal bacterial and fungal flora of the conjunctival sac has been described in horses and other animals. The identification of commensal flora of the conjunctival sac may aid in the diagnosis of ocular inflammatory diseases, such as conjunctivitis or more severe ulcerative keratitis, common in horses. Moreover, damage of ocular protective barriers may lead to an opportunistic infection.

Occurrence of reproductive disorders in pig herds with and without Chlamydia suis infection - statistical analysis of breeding parameters.

Chlamydiae are frequently encountered Gram-negative intracellular eubacteria that can cause clear manifestations or clinically asymptomatic disorders. C. suis and other chlamydia are primarily isolated in cases of reproductive disorders.

Molecular analysis of Trichomonas gallinae in racing pigeons from Upper Silesia, Poland.

The aim of the study was the molecular analysis of ITS1/5.8S rRNA/ITS2 region of Trichomonas gallinae isolates from racing pigeon lofts in Upper Silesia, Poland. The analysed region is very useful for the taxonomy of the Trichomonadidae family and indicates the possible existence of different genotypes or species within the T.
