Molecular survey and genetic characterization of tick-borne pathogens in dogs in metropolitan Recife (north-eastern Brazil).

To identify DNA of the main tick-borne pathogens in dogs from Recife (Brazil), polymerase chain reactions were carried out on blood samples of dogs treated at the Veterinary Hospital of the Universidade Federal Rural de Pernambuco from March 2007 to June 2008. The detection of DNA was performed using specific primers. Amplicons were analyzed through electrophoresis and sequencing. A phylogenetic tree was constructed using the UPGMA method, revealing that the sequences were closely related to those of strains from other geographic regions. Among the 205 blood samples analyzed, 48.78% was positive for Anaplasma platys; 38.04% was positive for Ehrlichia canis; 7.31% was positive for Babesia canis vogeli; and 0.49% was positive for Hepatozoon canis and Mycoplasma haemocanis. Coinfection of two or three pathogens was found in 23.9% (49/205) of the dogs. The subspecies B. canis vogeli was identified. Infection by H. canis and M. haemocanis is reported for the first time in dogs in the state of Pernambuco (Brazil). The data indicate that the main tick-borne pathogens in dogs in this region are E. canis and/or A. platys, followed by B. canis vogeli.

European Union (EU) general farm animal directive applicability in Africa and bovine welfare assessment in Italy

The was conducted with objectives focusing on the EU farm animal directive and applicability in Africa focusing in Ethiopia, the welfare assessment and the effect of different bovine respiratory disease (BRD) treatment protocols in beef cattle fattening unit and the calves navel healing and fitness for transport. Different methodology was applied: relevant literates, international organization, regional organization, countries legislations, standards were assessed and reviewed, for assessing beef welfare and biosecurity a modified version of the Italian protocol for assessing beef cattle was adopted which is part of the ClassyFarm monitoring scheme, 264 Limousine bulls with an average age of 11 months at the entrance to fattening unit were considered. Mycoplasma bovis was tested using RT-PCR at arrival and with culture at after 15 days of arrival to the fattening unit. For studying the navel healing and effect on transport the navels of 299 dairy calves (55 males, 244 females) aged 0–90 days were examined. As a conclusion, the European Union (EU) farm directive, could not be completely implement in African countries like Ethiopia, but it could serve as a good starting point, so as after successful identification of the farm animal welfare critical points may help as a starting point with modification to the local situation in the ground. In beef welfare assessment, integration of different assessment parameters could be of useful, when assessing beef welfare, and further continues detail physiological parameters of welfare assessment for integration with other assessment protocols should be studied, our finding indicate that also BRD was a major welfare and health concern in the studied population and evidence the difficulties of antimicrobial treatment of M. bovis associated BRD. In transporting calves with a completely healed navel should be considered best practice because it ensures that calves that are too young are not transported.
