In order to clarify the intraspecies taxonomic position of the non-photosynthetic algal species Prototheca zopfii, as well as the aetiology of bovine mammary protothecosis, a selection of P. zopfii strains isolated from clinical cases of protothecal mastitis and from various environmental habitats was characterized using a polyphasic molecular approach.(More)
AIM To gain deeper insight into the seroprevalence of brucellosis, which remains a zoonotic disease of worldwide public health concern, by reviewing studies from countries including North Africa, the Middle East, and India. METHODS Studies on brucellosis performed in countries that are neighbors or important trading partners of the European Union and on(More)
In order to clarify the epidemiology of bovine protothecal mastitis, 30 Prototheca zopfii mastitis isolates were genetically investigated. Based on the 18S rDNA, which allows a differentiation of the former species P. zopfii in two distinct P. zopfii genotypes and Prototheca blaschkeae sp. nov., newly developed genotype-specific PCR-assays as well as(More)
Bovine mastitis due to unicellular, achlorophyllous algae of the genus Prototheca is a serious and complex ailment that accounts for high economic losses in the dairy industry. Bovine protothecal mastitis has been almost exclusively associated with only one species Prototheca zopfii. Recently, based on the 18S rDNA sequence analysis, P. zopfii has been(More)
Camels are highly susceptible to brucellosis caused by Brucella melitensis and Brucella abortus. Difficulties can arise in diagnosis of camel brucellosis, especially as this disease provokes only few clinical signs in contrast to its clinical course in cattle. Because none of the commonly used serological test can be perceived as a perfect test for Brucella(More)
The occurrence of laMRSA (livestock-associated methicillin-resistant Staphylococcus aureus) and extended-spectrum beta-lactamase (ESBL) and/or plasmid-mediated AmpC beta-lactamase-producing (AmpC) Enterobacteriaceae in healthy livestock herds is known for some time.The spread of these bacteria in the environment is discussed critically.The object of this(More)
