Background: Angiostrongylus vasorum is a potentially fatal canine nematode. Due to the high variability of clinical signs and the often chronic and subtle course of the infections, the diagnosis is particularly challenging. A rapid in-clinic assay (Angio Detect™ Test, IDEXX Laboratories, Westbrook, Maine, USA) for the serological detection of circulating antigen and intended for routine in-clinic diagnosis has been evaluated. Methods. Sensitivity was calculated with sera from 39 naturally infected dogs confirmed by Baermann-Wetzel analysis, while sera of 38 experimentally infected dogs were used for follow-up analyses, of which 10 were treated with imidacloprid/ moxidectin. Cross-reactivity was tested with a total of 123 samples from dogs with proven parasitic infections with Toxocara canis (n = 21), Ancylostoma caninum (n = 4), Crenosoma vulpis (n = 18), Oslerus osleri (n = 3), Eucoleus aerophilus, (n = 6), Dirofilaria immitis (n = 28), Dirofilaria repens (n = 20), Acantocheilonema reconditum (n = 10) or Dipetalonema dracunculoides (n = 10) or multiple infections (n = 3). All sera were tested with the Angio Detect™ Test and with an ELISA for detection of circulating antigen of A. vasorum. Results: The sensitivity of the Angio Detect™ Test was 84.6% (95% C.I. 69.5 - 94.1%), while specificity was 100% (95% C.I. 97.6 - 100%). The sensitivity of the ELISA (94.9%, 95% C.I. 82.7 - 99.3%) was comparable with previous evaluations. In experimentally infected dogs, earliest positive results with the Angio Detect™ Test were observed 9 weeks post inoculation and 5 weeks later all sera were Angio Detect™ Test positive. After anthelmintic treatment, seropositive dogs turned negative again within 3 to 7 weeks after treatment. The evaluation of the colour intensity of the test strips confirmed the delay of approximately 3-4 weeks for antigen detection by the Angio Detect™ Test compared to the ELISA and its correlation with the time after infection. Conclusions: This study provided evidence of a good sensitivity and a very high specificity of the rapid device Angio Detect™ Test for detection of circulating A. vasorum antigen in dogs with suspected canine angiostrongylosis, representing a very simple and useful tool to be broadly applied in veterinary practices. The rapid detection of infected dogs is a key point for initiating an indispensable and urgent therapy. © 2014 Schnyder et al.; licensee BioMed Central Ltd. Source

Background: Gammaherpesviruses (GHVs) are a large group of dsDNA viruses that can infect humans and several animal species. The two human GHVs, Epstein-Barr virus and Kaposi's sarcoma-associated herpesvirus are known for their oncogenic properties in individuals with immunodeficiency. Recently, the first feline GHV, Felis catus gammaherpesvirus 1 (FcaGHV1) was discovered and frequently found in domestic cats in Australia, Singapore and the USA. FcaGHV1 is more likely to be detected in cats co-infected with the feline immunodeficiency virus (FIV). Findings: The prevalence of FcaGHV1 in pet cats from Germany and Austria was 16.2 % (95 % CI∈=∈12.38-20.02). The odds for GHV infection were greater for FIV positive (OR∈=∈4.5), male (OR∈=∈13.32) and older (OR∈=∈2.36) cats. Furthermore, FcaGHV1 viral loads were significantly higher in FIV-infected cats compared to matched controls. Conclusions: GHV infections are common in domestic cats in Central Europe. The worldwide distribution of FcaGHV1 can be assumed. A potential role as a co-factor in FIV-induced pathogeneses is supported. © 2015 Ertl et al. Source

Objectives: The aim of this study was to determine the MICs of 32 antimicrobial agents for 200 isolates of Rhodococcus equi of animal origin by applying a recently described broth microdilution protocol, and to investigate isolates with distinctly elevated rifampicin MICs for the genetic basis of rifampicin resistance. Methods: The study included 200 R. equi isolates, including 160 isolates from horses and 40 isolates from other animal sources, from the USA and Europe. MIC testing of 32 antimicrobial agents or combinations thereof followed a recently published protocol. A novel PCR protocol for the joint amplification of the three rpoB regions in which rifampicin resistance-mediating mutations have been reported was applied to isolates with elevated rifampicin MICs. The amplicons were sequenced and screened for mutations. Results: Susceptibility testing revealed a rather uniform distribution of MICs for most of the antimicrobial agents tested. The lowest MICs were seen for clarithromycin, rifampicin and imipenem. Six isolates (3%) exhibited distinctly higher MICs of rifampicin than the remaining 194 isolates. In five of these six isolates, single bp exchanges, which resulted in the amino acid exchanges Gln513Leu, Asp516Val, His526Asp or Ser531Leu, were detected in the rifampicin resistance-determining region 1 of the rpoB gene, with Gln513Leu representing a novel substitution for R. equi. Conclusions: This study shows the MIC distribution of 32 antimicrobial agents for a large collection of R. equi isolates of animal origin from two continents. Isolates that exhibited distinctly elevated MICs of rifampicin were only rarely detected. © The Author 2013.

During an entomology survey in July 2009 and July 2010, 4 males and 22 females of Phlebotomus (Transphlebotomus) mascittii were caught in southeastern Carinthia. These are the first documented records of the occurrence of Phlebotominae in Austria. © 2011 Springer-Verlag. Source

Background. With the import of pets and pets taken abroad, arthropod-borne diseases have increased in frequency in German veterinary practices. This is reflected by 4,681 dogs that have been either travelled to or relocated from endemic areas to Germany. The case history of these dogs and the laboratory findings have been compared with samples collected from 331 dogs living in an endemic area in Portugal. The various pathogens and the seroprevalences were examined to determine the occurrence of, and thus infection risk, for vector-borne pathogens in popular travel destinations. Results. 4,681 dogs were examined serological for Leishmania infantum, Babesia canis and Ehrlichia canis. Buffy coats were detected for Hepatozoon canis and blood samples were examined for microfilariae via the Knott's test. The samples were sent in from animal welfare organizations or private persons via veterinary clinics. Upon individual requests, dogs were additionally examined serological for Anaplasma phagocytophilum, Borrelia burgdorferi and Rickettsia conorii. Overall B. canis was the most prevalent pathogen detected by antibody titers (23.4%), followed by L. infantum (12.2%) and E. canis (10.1%). Microfilariae were detected in 7.7% and H. canis in 2.7% of the examined dogs. In 332/1862 dogs A. phagocytophilum, in 64/212 B. burgdorferi and in 20/58 R. conorii was detected. Of the 4,681 dogs, in total 4,226 were imported to Germany from endemic areas. Eighty seven dogs joined their owners for a vacation abroad. In comparison to the laboratory data from Germany, we examined 331 dogs from Portugal. The prevalence of antibodies/pathogens we detected was: 62.8% to R. conorii, 58% to B. canis, 30.5% to A. phagocytophilum, 24.8% to E. canis, 21.1% to H. canis (via PCR), 9.1% to L. infantum and 5.3% to microfilariae. Conclusions. The examination of 4,681 dogs living in Germany showed pathogens like L. infantum that are non-endemic in Germany. Furthermore, the German data are similar in terms of multiple pathogen infection to the data recorded for dogs from Portugal. Based on these findings the importation of dogs from endemic predominantly Mediterranean regions to Germany as well as travelling with dogs to these regions carries a significant risk of acquiring an infection. Thus we would conclude that pet owners seek advice of the veterinarians prior to importing a dog from an endemic area or travel to such areas. In general, it might be advisable to have a European recording system for translocation of dogs. © 2010 Menn et al. Source
