A cross-sectional survey was performed to estimate the prevalences of antibodies to Toxoplasma gondii (ELISA, IFAT), Sarcocystis spp. (ELISA, using S. miescheriana as antigen) and Neospora caninum (ELISA, immunoblotting) in sows from breeding farms in southern Hesse, Germany. A total of 2041 plasma samples of sows from 94 randomly selected farms was examined. Data on farm profiles, husbandry ma...

background: coccidiosis is a serious protozoal disease of poultry. the iden-tification of eimeria species has important implications for diagnosis and con-trol as well as for epidemiology. the molecular characterization of eimeria spe-cies infecting egyptian baladi chickens was investigated. methods: eimeria species oocysts were harvested from intestines of naturally infected egyptian baldi chi...

respiratory diseases are considered as common disorders in broiler farms. over the past decade a pleomorphic gram negative bacteria which isolated from broilers with respiratory diseases now calls ornithobacterium rhinotracheale . in this study, samples from trachea and lung collected from chicken with clinical respiratory signs in 173 broiler farms and then subjected on bacterial culture. the ...

There are few published studies describing the unique management practices, farm design and housing characteristics of commercial meat chicken and layer farms in Australia. In particular, there has been a large expansion of free range poultry production in Australia in recent years, but limited information about this enterprise exists. This study aimed to describe features of Australian commerc...

To identify the reservoirs of shiga toxin-producing Escherichia coli O157, sensitive detection andisolation methods are necessary. The sensitivity of traditional culture methods can be improved significantlyby the inclusion of an immunoconcentration step, resulting in less false-negative results. In this study,enrichment procedure and immunomagnetic separation (IMS) were compared for use in con...

To ascertain whether on animal farms there reside extended-spectrum beta-lactamase (ESBL) and plasmidic class C beta-lactamase-producing Escherichia coli isolates potentially pathogenic for humans, phylogenetic analyses, pulsed-field gel electrophoresis (PFGE) typing, serotyping, and virulence genotyping were performed for 86 isolates from poultry (57 isolates) and pig (29 isolates) farms. E. c...

The present study was conducted to compare aqueous nanoparticle-based Montanide™ IMS 1313 N VG PR (IMS 1313) and oil-based ISA 71 VG (ISA71) adjuvants in combination with an Eimeria subunit protein vaccine on protection against avian coccidiosis. Male broiler chicks were vaccinated twice with an Eimeria recombinant profilin protein alone or in conjunction with IMS 1313 or ISA 71 prior to infect...

post inoculation. Across all isolates there was a linear improvement in performance and decrease in coccidiosis lesions. Within all categories there were not significant differences between the NMI and N125 except for E. acervulina lesion scores (NMI 0.0 and N125 0.4). All other treatments and categories were significantly different. Feed conversions were NMU 1.447, NMI 2.594, N36 1.956, N72 1....
