The family Chlamydiaceae with the recombined single genus Chlamydia currently comprises nine species, all of which are obligate intracellular organisms distinguished by a unique biphasic developmental cycle. Anecdotal evidence from epidemiological surveys in flocks of poultry, pigeons and psittacine birds have indicated the presence of non-classified(More)
Francisella tularensis subsp. holarctica isolates from Austria, Germany, Hungary, Italy, and Romania were placed into an existing phylogeographic framework. Isolates from Italy were assigned to phylogenetic group B.FTNF002-00; the other isolates, to group B.13. Most F. tularensis subsp. holarctica isolates from Europe belong to these 2 geographically(More)
Ocular adnexal MALT lymphoma (OAML) is linked to Chlamydophila psittaci (Cp) infection. Viability and infectivity of Cp, demonstrated by growth in culture, has not been yet investigated in these patients. We conducted a single-center prospective case-control study to assess the prevalence, viability and infectivity of Cp in 20 OAML patients and 42 blood(More)
Bartonella henselae is the major etiological agent of Cat Scratch Disease in humans. Cats act as the natural reservoir of B. henselae and can transmit the infection to humans by bite or scratch. The diffusion of B. henselae was evaluated by seroprevalence and bacteremic status in different stray cat populations located in nine areas of Northern Italy. A(More)

Twenty-five percent of ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma (OAML) patients have disseminated disease (distant nodal and/or extranodal lesions) [1]. These patients are usually treated with chemotherapy, which is active though, sometimes, too toxic, or with rituximab, which is better tolerated but has only transient activity.(More)
BACKGROUND Tularemia is a zoonosis caused by the Francisella tularensis, a highly infectious Gram-negative coccobacillus. Due to easy dissemination, multiple routes of infection, high environmental contamination and morbidity and mortality rates, Francisella is considered a potential bioterrorism threat and classified as a category A select agent by the(More)
Due to an unfortunate turn of events, the first-and surname of the sixth author was transposed and a typographical error was introduced in the title of the original publication. The correct representation of the authors, their affiliations, and the title are listed above and below and should be treated as definitive by the reader.
Ticks are the main vectors of rickettsiae of the spotted fever group, as well as of a variety of other Rickettsiales, including bacteria of the genus Anaplasma, that might cause diseases in humans and animals. Here we present the result of a survey for ticks and for tick-associated Rickettsiales in the Emilia Romagna region (Northern Italy). The study was(More)
We describe a novel high-resolution melt assay that clearly differentiates Chlamydia abortus live vaccine strain 1B from field C. abortus strains and field wild-type isolates based on previously described single nucleotide polymorphisms. This modern genotyping technique is inexpensive, easy to use, and less time-consuming than PCR-RFLP.
