Little is known about the significance of mycoplasmas in different free-ranging bird species. One hypothesis that prevalence and influence vocalization on reproduction are evolutionarily linked. To add another piece information toward proving or disproving this obtain more clinical relevance mycoplasmas, choanal swabs from passerine species presented to a veterinary clinic were examined for using culture Mycoplasma genus-specific PCR. When detected, was identified by sequencing partial 16S...
Newcastle Disease (ND) is a viral disease spread worldwide with high impact on economy and animal welfare. Vaccination against one of the main control measures in countries such as Germany endemic occurrence virus free ranging bird population. The German Standing Veterinary Committee Immunization (StIKo Vet) recommends to revaccinate chickens at intervals six weeks attenuated live vaccines via drinking water or spray line SPCs (Summary Product Characteristics) current vaccines. However, it...
Mycoplasma gallisepticum and synoviae are bacterial pathogens that cause disease in poultry, adversely affecting their health welfare, a financial burden on producers. This manuscript describes the results of MycoPath project is first international antimicrobial susceptibility programme for mycoplasma isolated from poultry. Improved comparative analysis minimal inhibitory concentration (MIC) participating countries was facilitated by using one laboratory determining all MICs. Chicken turkey...
The mycoplasma strain ST 57T was isolated from the trachea of a clinically healthy, free-ranging white stork nestling in Nielitz, Mecklenburg-Western Pomerania, Germany. Strain grew fried-egg-shaped colonies on (SP4) agar plates and dependent sterol for growth. organism fermented glucose did not hydrolyse arginine or urea. optimal growth temperature 37 °C, with range 23 to 44 °C. 57Tcould be identified as representative any currently described species by alignment 16S rRNA gene sequence...
Mycoplasma species are well known pathogens in avian medicine, especially poultry. However, several have been regularly found the respiratory tract of birds prey which seem to be commensals these bird species. In previous studies, an unknown caused false positive results a meleagridis -specific PCR, was isolated from tracheal swab clinically healthy, captive, adult peregrine falcon (Falco peregrinus). The isolate appeared typical fried-egg-shaped colonies on SP4 agar plates and dependent...
Abstract In poultry industry, mycoplasmas cause large economic losses. The pathogenic significance of varies widely between species. birds where vocalization is crucial for reproductive success, seem to be absent. Birds with high mycoplasma prevalence like prey and storks do not rely on their reproduction. Corvids an intermediate use other strategies besides mating. It hypothesized that used reproduction evolutionary related. Barn swallows have two traits relevant mating: tail feather length...
Several Mycoplasma spp. are well-known pathogens in poultry. In birds of prey, White Storks ( Ciconia ciconia ), and some waterfowl (Anatidae, Pelecanidae) species, mycoplasmas occur commonly seem to be apathogenic or commensal most likely belong the physiologic microbial flora respiratory tract. other bird such as Common Nightingales Luscinia megarhynchos ) tits (Paridae), absent healthy birds. corvids, prevalence role disease remains unclear. previous studies, sturni was detected diseased...
An alternative to culling male hatchlings of layers is breeding dual-purpose chickens. One objective the ability digest low-quality feed. Certain measurements gastrointestinal tract may be useful indicators this ability. The present study compared adult hens two layer-type breeds (White Rock (WR), New Hampshire (NH)) and meat-type ÖTZ (Ökologische Tierzucht gGmbH) Bresse Gauloise (BR), used for production organic Flocks had same housing feeding conditions. At slaughter at 19 months, body...

The identification of avian Mycoplasma spp. by conventional immunologic, phenotypic, and molecular methods can be demanding time-consuming. We evaluated MALDI-TOF MS for its suitability to identify mycoplasmas at the species level. generated a mycoplasma spectral database 36 main spectrum profiles (MSPs) representing 23 using type reference strains, 1 live vaccine strain, 8 clinical isolates. then used 112 isolates different mycoplasmas, 4 previously cultured identified level methods,...
Abstract Mycoplasma spp. are important pathogens in poultry and cause high economic losses for industry worldwide. In other bird species (e.g. white storks, birds of prey, several waterfowl species), regularly found healthy individuals, hence, considered apathogenic or part the microbiota upper respiratory tract. However, as absent individuals some wild species, they might play a role pathogen these e.g. gallisepticum house finches. The knowledge on occurrence is limited. To evaluate...
