Background: A study on tick species characterization and tick borne pathogens detection was performed by a survey conducted during 2012 and 2013 in the Viterbo province (Lazio Region, Central Italy). Seven sites were selected for the study investigation, including two farms and a military zone.
Methods: A total of 255 ticks, Rhipicephalus (Boophilus) annulatus (n = 215), Rhipicephalus bursa (n = 28), and Hyalomma marginatum (n = 12) were screened individually by molecular methods for the tick borne bacterial agents: Borrelia burgdorferi sensu lato group, Bartonella spp., Coxiella burnetii, Ehrlichia spp., Francisella spp., and Rickettsia spp.
Results And Conclusion: Overall, 182 ticks (71%) were infected with at least one pathogen; among these co-infections were found in 94 ticks. Tick borne pathogens identified were C. burnetii, B. burgdorferi s.l., Bartonella spp., Rickettsia spp., Francisella spp., and Ehrlichia spp. In R. bursa and H. marginatum, the presence of B. burgdorferi s.l. was positively correlated with that of C. burnetii, Rickettsia spp., and Bartonella spp. and their coinfection probabilities were 29.8%, 22.7% and 11.7%, respectively; the probability of coinfection for Francisella spp. and Rickettsia spp. and for Francisella spp. and Bartonella spp. was 14.9% and 17.9%, respectively. In R. (Boophilus) annulatus, the probability of coinfection between C. burnetii and B. burgdorferi s.l. was 11.3%, while those between C. burnetii and Bartonella spp. and between B. burgdorferi s.l. and Bartonella spp. were 0.8%. Further studies are needed in order to assess the risk associated with these unusual tick-borne pathogens in Central Italy.

A 13-y-old, spayed female dog had regenerative anemia, lymphopenia, hypoalbuminemia, and elevated hepatic biochemical parameters. Liver biopsy revealed hepatic peliosis (hepatic sinusoidal angiectasis), frequently associated with perisinusoidal fibrosis. The dog was seroreactive to antigens by indirect fluorescent antibody assays, and quantitative PCR from blood identified subsp.

More than one-hundred species that affect animals and humans have been described, eight of which have been associated with emerging and underdiagnosed zoonoses. Most diagnostic studies in humans have used serology or molecular assays based on the 18S rRNA gene. Because the 18S rRNA gene is highly conserved, obtaining an accurate diagnosis at the species level is difficult, particularly when the amplified DNA fragment is small.

Background: Acute febrile illness is a common reason for seeking healthcare in low- and middle-income countries. We describe the diagnostic utility of a TaqMan Array Card (TAC) real-time polymerase chain reaction (PCR) panel for pathogen detection in paediatric and adult inpatients admitted with febrile illness.
Methods: In this prospective cohort study, we screened medical admissions for a tympanic temperature ≥38.

Raccoons (Procyon lotor) originated in North America and have been introduced to Europe. Due to their close contact with human settlements, they are important reservoirs for zoonotic pathogens, such as Baylisascaris procyonis. The relevance and prevalence of vector-borne pathogens have not yet been fully elucidated.

Bartonella spp. are gram-negative bacteria recognized as zoonotic pathogens of wide spectrum mammals. Rodents are recognized as a natural reservoir of pathogens, and many Bartonella species transmitted by various blood-sucking arthropods have been detected in various rodents populations.
