Canine and feline cardiorespiratory parasites are of utmost relevance in veterinary medicine. Key epizootiological information on major pet metastrongyloids, i.e., Angiostrongylus vasorum and Crenosoma vulpis infecting dogs, and Aelurostrongylus abstrusus and Troglostrongylus brevior infecting cats, is missing from Austria. This study investigated their occurrence in 1320 gastropods collected in the Austrian provinces of Styria, Burgenland, Lower Austria, and in metropolitan Vienna. Metastrongyloid larvae were microscopically detected in 25 samples, and sequence analysis confirmed the presence of metastrongyloids in nine samples, i.e., A. vasorum in one slug (Arion vulgaris) (0.07%), C. vulpis in five slugs (one Limax maximus and four A. vulgaris) (0.4%), A. abstrusus in two A. vulgaris (0.17%), and the hedgehog lungworm Crenosoma striatum was detected in one A. vulgaris. The present study confirms the enzooticity of major cardiorespiratory nematodes in Austria and that canine and feline populations are at risk of infection.

Abstract Background Metastrongyloid parasites Angiostrongylus vasorum and Crenosoma vulpis infect wild and domestic canids and are important pathogens in dogs. Recent studies indicate that gastropod intermediate hosts infected with various metastrongyloids spontaneously shed infective third-stage larvae (L3) into the environment via feces and mucus under laboratory conditions. Shed L3 retain motility up to 120 days, but whether they retain infectivity was unknown. Methods To assess the infectivity of shed L3, the heart/lungs of six red foxes (Vulpes vulpes) were obtained from trappers in Newfoundland, Canada. Lungs were examined for first-stage larvae (L1) by the Baermann technique. A high number of viable A. vasorum L1 and a low number of C. vulpis L1 were recovered from one fox; these were used to infect naïve laboratory-raised Limax maximus. L3 recovered from slugs by artificial digestion were fed to two naïve purpose-bred research beagles (100 L3/dog). L1 shed by these two dogs was used to infect 546 L. maximus (2000–10,000 L1/slug). L3 shedding was induced by anesthetizing slugs in soda water and transferring them into warm (45 °C) tap water for at least 8 h. Shed L3 recovered from slugs were aliquoted on romaine lettuce in six-well tissue culture plates (80–500 L3/well) and stored at 16 °C/75% relative humidity. Four naïve research beagles were then exposed to 100 L3/dog from larvae stored for 0, 2, 4, or 8 weeks, respectively, after shedding. Results All four dogs began shedding C. vulpis L1 by 26–36 days post-infection (PI). All four dogs began shedding A. vasorum L1 by 50 days PI. Conclusions L3 infectivity for the definitive host was retained in both metastrongyloids, indicating the potential for natural infection in dogs through exposure from environmental contamination. As an additional exposure route, eating or licking plant or other material(s) contaminated with metastrongyloid L3 could dramatically increase the number of dogs at risk of infection from these parasites.

Risk Areas

Cats infected with the metastrongylid nematode Aelurostrongylus abstrusus may show clinical signs ranging from mild to severe respiratory disease or remain unobserved, despite damages present in the lung tissue. This study aimed to determine the seroprevalence and distribution of A. abstrusus in cats by testing serum samples from all over Germany to identify potential risk areas and strengthen disease awareness accordingly. Sera of 2998 cats were screened for the presence of antibodies against A. abstrusus by ELISA, and the data were evaluated by a geographic information system to visualise the regional distribution of the analysed samples. Overall, 12.0% of the samples tested positive (361/2998 cats, 95% confidence interval: 10.9–13.3%). Seropositive cats were identified throughout the country, suggesting that all cats in Germany with outdoor access are at risk of A. abstrusus infection and that the infection is overall underdiagnosed. Increased testing for A. abstrusus infection would allow earlier detection of infected animals, hence improving the life quality and health of cats and preventing potential death under anaesthesia.

ZusammenfassungNeue Arbeiten zum Lungenwurmbefall bei Hunden signalisieren, dass sich das Infektionsrisiko für Hunde in Deutschland in den letzten Jahren möglicherweise erhöht hat. Auswertungen von Kotuntersuchungen zeigen außerdem, dass Angiostrongylus vasorum, Crenosoma vulpis und Eucoleus aerophilus bei Hunden in Deutschland endemisiert sind. Von insgesamt 223 mit A. vasorum infizierten Hunden waren 102 in Baden-Württemberg beheimatet, 65 in Nordrhein-Westfalen, 27 im Saarland, 15 in Bayern, 7 in Rheinland-Pfalz, 5 in Hessen und 2 in Brandenburg. Von 170 C.-vulpis-positiven Hunden lebten 54 in Nordrhein-Westfalen, 40 in Baden-Württemberg, 30 in Bayern, jeweils 17 in Rheinland-Pfalz und im Saarland, 9 in Hessen und jeweils 1 Hund in Niedersachen, Berlin und Mecklenburg-Vorpommern. Ein Befall mit E. aerophilus wurde bei 83 Hunden festgestellt, von denen 23 aus Baden-Württemberg, 20 aus Nordrhein-Westfalen, 17 aus Bayern, 11 aus Rheinland-Pfalz, 7 aus Hessen, 4 aus dem Saarland und 1 Hund aus Mecklenburg-Vorpommern stammten. Die Ergebnisse zeigen, dass Infektionen mit Lungenwürmern bei Hunden in vielen Gebieten in Deutschland etabliert sind. Mit der vorliegenden Arbeit sollen die wesentlichen Fakten der Erkrankung zusammengestellt und ein Überblick über Vorkommen und Verbreitung, zur Klinik, Diagnose und Therapie der Lungenwurminfektionen beim Hund gegeben werden.

South African radiologists performing interventional and angiographic procedures are at risk of occupational exposure to hepatitis Band C and the human immunodeficiency virus (HIV). Simple precautions reduce this risk substantially. It is important that radiologists and personnel working in the interventional suite are aware of the risk of infection, how to reduce the risk and how to prevent seroconversion after needle stick injuries.
