After the repeated demonstration of Dirofilaria repens infections in German dogs, D. repens and Dirofilaria immitis DNA was detected in mosquitoes trapped in 2011, 2012 and 2013 in northeastern and southwestern Germany within the framework of culicid monitoring projects. As temperature is the most important factor dictating the extrinsic development of dirofilarial larvae in the potential vector, data of the German Weather Service (DWD) were analysed for the regions where the positive mosquitoes had been collected. Based on the mean daily temperatures recorded by weather stations most closely to the collection sites of the mosquitoes, it can be concluded that the mosquitoes were trapped in time periods that allowed for the completion of the developmental cycle of the worms in the mosquitoes and a subsequent transmission to a vertebrate host. The results of this study confirm the principal climatic suitability of certain German regions for the establishment of natural dirofilarial transmission cycles. Moreover, the theoretical climatic considerations, together with findings of D. repens infections in German dogs and mosquitoes, strongly suggest that the continuing spread of at least D. repens from its traditional habitats in the Mediterranean has reached southwestern and northeastern Germany. © 2014 Springer-Verlag.

Molecular Genetics and Metabolism

This case-series describes fourteen horses suspected of equine acquired multiple acyl-CoA dehydrogenase deficiency (MADD) also known as atypical myopathy of which seven cases were confirmed biochemically with all horses having had access to leaves of the Maple tree (Acer pseudoplatanus) covered with European tar spot (Rhytisma acerinum). Assessment of organic acids, glycine conjugates, and acylcarnitines in urine was regarded as gold standard in the biochemical diagnosis of equine acquired multiple acyl-CoA dehydrogenase deficiency. © 2010 Elsevier Inc.

The aim of this study was to assess the concentration of penicillin G in mammary tissue and secretion of dry heifers following systemic administration of penethamate hydriodide. Six dairy heifers in late gestation received a single intramuscular injection of 10 g penethamate hydriodide and were sacrificed 24, 48 or 144 h after treatment. Penicillin G concentrations were measured in mammary tissue and secretion samples using HPLC. Penicillin G was detected in the udder of two animals euthanized at 24 h (mammary tissue and secretion) and at 48 h post treatment (mammary secretion only) after administration at concentrations still close to or above MIC90 values reported for the pathogens associated with heifer mastitis. Antibiotic concentration shortly after administration will have been substantially higher indicating a potential for systemic treatment with penethamate hydriodide to control prepartum intramammary infections in heifers without the disadvantages of local therapy such as teat contamination or risk of trauma for the administrator. © 2009 Proprietors of Journal of Dairy Research.

Pathogens and Disease

Chlamydia psittaci is a zoonotic pathogen associated primarily with avian chlamydiosis also referred as psittacosis. Human psittacosis can lead to severe cases of respiratory disease. The mule duck is one of the main bird hybrids associated with human cases of psittacosis in France. In order to better understand the epidemiology of avian chlamydiosis, monitoring studies were performed in both breeder flocks and mule duck flocks. Surveys conducted in one professional duck bredding organization revealed little shedding in breeder flocks, whereas heavy but asymptomatic C. psittaci shedding was observed in most of the mule duck flocks, mostly when birds were reared in open range conditions on farms. Human cases of psittacosis linked to duck breeder flocks and their progeny led to detection of heavy shedders in all the suspected flocks despite no birds showing clinical signs. Offspring of one of the infected female flocks was analyzed and also proved to be infected by C. psittaci. Field studies suggest that C. psittaci infections in duck farms involve horizontal and probably vertical transmission but that the environment also plays an important role in maintaining infection on farms. In the light of the widespread occurrence of C. psittaci on duck farms, it has become urgent to clearly identify sources of contamination in order to take appropriate field management measures to minimize worker exposure. © FEMS 2014.

Trichotillomania (TTM) is most frequently characterized by small bald spots on the posterior part of the body of dogs and cats. The disease arises on a psychogenic basis and is a consequence of distress: the animal deprives itself of hair and brings about skin lesions by intensively licking its body. It has been relatively rarely described in cats and, in the case discussed here, is unique in view of the described recurrence. This study presents TTM occurring in a female cat in the second month of life with a recurrence after four years. Source
