Abstract:
... RT-PCR was used to detect canine distemper virus (CDV) RNA in clotted blood from Argentine domestic dogs. The NP gene was detected in 73 out of 99 blood samples analyzed. The deduced amino acid sequence of these gene fragments showed 100% identity with the sequence of other wild-type and vaccine strains. A fragment of the hemagglutinin gene was amplified from 24 (32.9%) of the NP-RNA-positive clin ...

Abstract:
... Paenibacillus larvae is the causal agent of American Foulbrood (AFB) disease, the most virulent bacterial disease of honeybee (Apis mellifera L.) brood. Oxytetracycline is the main antibiotic used for prevention and control of AFB. Using the polymerase chain reaction, isolates were screened for the presence of the tetracycline resistance tet(K) and tet(L) determinants. Four isolates (5%), which co ...

Abstract:
... Hemotropic mycoplasmas (aka hemoplasmas) are the causative agents of infectious anemia in numerous mammalian species. Originally known as Haemobartonella and Eperythrozoon species, these organisms have been reclassified within the genus Mycoplasma. The development of new molecular assays has expanded our knowledge of this heterogeneous group of agents and allowed us to study their epidemiology and ...

Abstract:
... This cross-sectional study was conducted to determine the prevalence and antimicrobial resistance of Salmonella species in swine reared in the intensive (indoor) and extensive (outdoor) ABF production systems at farm and slaughter in North Carolina, U.S.A. We sampled a total of 279 pigs at farm (extensive 107; intensive 172) and collected 274 carcass swabs (extensive 124; intensive 150) at slaught ...

Abstract:
... The objective was to study the prevalence of antimicrobial resistance and the mechanisms implicated in faecal enterococci of wild boars in Portugal. One hundred and thirty-four enterococci (67 E. faecium, 54 E. hirae, 2 E. faecalis, 2 E. durans and 9 Enterococcus spp.) were recovered from 67 wild boars (two isolates/sample), and were further analysed. High percentages of resistance were detected f ...

Abstract:
... Cryptococcosis is considered a zoonosis but is rare in stock animals. In humans it is imputed to be a mortality cause in immunocompromised patients. This case study reports the anatomopathology of respiratory cryptococcosis in ovine and the recuperation and identification of Cryptococcus neoformans var. neoformans from 1-year frozen lung tissue sample. The findings from haematoxylin/eosin staining ...

Abstract:
... The purpose of this study was to characterize, at the molecular level, the Ehrlichia canis strains involved in naturally occurring canine monocytic ehrlichiosis (CME) in Greece, and to investigate if any sequence diversity exists between the 16S rRNA genes of those involved in the mild non-myelosuppressive or the severe myelosuppressive form of CME. To this end, amplification of the ehrlichial 16S ...
