Canine angiostrongylosis is a nematode infection in domestic dogs and wild carnivores. Few single case reports describing the occurrence of this disease in Germany exist and until recently angiostrongylosis has not been considered endemic in this country. The present report focuses on clinical, pathological and parasitological findings in two cases of fatal… (More)
Host-seeking Ixodes ricinus (L.) (Acari: Ixodidae) ticks were collected systematically, from May to September 2006, at selected sites in southern Germany, including a large city park in Munich. Polymerase chain reactions for amplification of genes of the rickettsial citrate synthase (gltA), the outer membrane proteins A and B (ompA and ompB), and the 16S… (More)
We have reinvestigated the morphology of the salivary glands in the cockroach, Periplaneta americana, by light, electron, and confocal laser scanning microscopy. All secretory acini have a uniform structural layout. They consist of three cell types: peripheral cells, central cells, and duct cells. One pair of peripheral cells forms the base of each acinus.… (More)
Anaplasma phagocytophilum DNA was detected by real-time PCR, which targeted the msp2 gene, in 2.9% of questing Ixodes ricinus ticks (adults and nymphs; n = 2,862), collected systematically from selected locations in Bavaria, Germany, in 2006. Prevalence was significantly higher in urban public parks in Munich than in natural forests.
Nine hundred and fifty-two fleas were collected from 148 cats and 133 dogs at 18 widely distributed geographic locations in Germany and France and examined for the presence of six different Bartonella spp. (Bartonella bacilliformis, Bartonella clarridgeiae, Bartonella elizabethae, Bartonella henselae, Bartonella quintana, Bartonella vinsonii subsp.… (More)
Carbonic anhydrase (CA) activity was localized in the salivery glands of the cockroach, Periplaneta americana, by (1) Hansson's histochemical technique, and (2) the use of the fluorescent sulphonamide, 5-dimethyl-amino-naphthalene-1-sulphonamide (DNSA). Both techniques reveal the same distribution pattern of CA in the four morphologically different cell… (More)
The acinous salivary glands of the cockroach (Periplaneta americana) consist of four morphologically different cell types with different functions: the peripheral cells are thought to produce the fluid component of the primary saliva, the central cells secrete the proteinaceous components, the inner acinar duct cells stabilize the acini and secrete a… (More)
A brain sample of a Natterer's bat tested positive for rabies with classical virological techniques. Molecular techniques confirmed the presence of Bokeloh bat lyssavirus (BBLV) in Germany for the second time. Sequence analysis revealed a close genetic relationship to the initial German BBLV case. Using a TaqMan RT-PCR specific for BBLV viral RNA was… (More)
We have isolated an iridescent virus from commercially produced colonies of Gryllus bimaculatus in Germany, which showed apparent mortality. Transmission electron microscopy studies on adult cricket specimens revealed the paracrystalline assembly of icosahedral virus particles in the cytoplasm of hypertrophied abdominal fat body cells. The infecting agent… (More)
Among 310 fleas collected from dogs and cats in Germany, Rickettsia felis was detected in all specimens (34) of Archaeopsylla erinacei (hedgehog flea) and in 9% (24/226) of Ctenocephalides felis felis (cat flea). R. helvetica was detected in 1 Ceratophyllus gallinae (hen flea).
