Rickettsia felis in Fleas, Western Australia

This study is the first confirmation of Rickettsia felis in Australia. The organism was identified from 4 species of fleas obtained from dogs and cats in Western Australia, by using polymerase chain reaction amplification and DNA sequencing of the citrate synthase and outer membrane protein A genes

Fleas as parasites of the family Canidae

Historically, flea-borne diseases are among the most important medical diseases of humans. Plague and murine typhus are known for centuries while the last years brought some new flea-transmitted pathogens, like R. felis and Bartonella henselae. Dogs may play an essential or an accidental role in the natural transmission cycle of flea-borne pathogens. They support the growth of some of the pathogens or they serve as transport vehicles for infected fleas between their natural reservoirs and humans. More than 15 different flea species have been described in domestic dogs thus far. Several other species have been found to be associated with wild canids. Fleas found on dogs originate from rodents, birds, insectivores and from other Carnivora. Dogs therefore may serve as ideal bridging hosts for the introduction of flea-borne diseases from nature to home. In addition to their role as ectoparasites they cause nuisance for humans and animals and may be the cause for severe allergic reactions

Sorveglianza microbiologica in una unità di terpia intensiva postoperatoria polispecialistica

bstract Surgery is the only curative treatment for primary hyperparathyroidism (pHPT). Surgical exploration is recommended for all patients with biochemically documented pHPT and signs or symptoms of the disease. Some patients are asymptomatic, others have subtle symptoms that disappear after parathyroid surgery. Felix Mandl successfully performed the first parathyroidectomy in 1925, using a bilateral neck exploration (BNE) with examination of all four glands and this remained the procedure of choice for pHPT into the 1990s. As over 80% of pHPT cases are due to a single parathyroid adenoma, many authors have questioned the need of BNE and have proposed directed unilateral approaches, termed "mini-invasive parathyroidectomies". The aim of this report is to define which is the actual role of the conventional surgical approach to pHPT

GNSS maps in environmental monitoring

© Springer International Publishing AG 2018. Traditionally, maps have been produced by plotting features on paper at a given scale, calling upon a variety of cartographic skills. The advent of computers, satellite data, and geographical information system (GIS), however, has revolutionized the art of map production, with the modern day cartographer required to master computer skills for the purpose of not only the production, but also the management of digital maps

Seroprevalence and risk factors for Rickettsia felis exposure in dogs from Southeast Queensland and the Northern Territory, Australia

Background: The recent detection of Rickettsia felis DNA in dogs in Australia suggests that dogs are potential mammalian reservoir hosts for this emerging rickettsia. To date, there is no published report addressing the seroprevalence of R. felis in dogs in Australia
