Arthropod-borne diseases: spreading of pathogens transmitted by hematophagous arthropods of human and veterinary concern
Arthropod-borne diseases are caused by several bacterial, viral and protozoal species and transmitted through the bite of hematophagous arthropods, mainly ticks whose spreading is strictly related to the climatic conditions. Most etiologic agents are zoonotic bacteria able to cause mild or severe clinical forms both in animals and humans. Some of these pathogens are well known, such as Borrelia burgdorferi sensu lato responsible for the Lyme disease and Rickettsia conorii, etiologic agent of the Mediterranean Spotted Fever. However, other arthropod-borne bacteria are circulating in Central Italy: Anaplasma phagocytophilum, Bartonella henselae and other Bartonella species, Coxiella burnetii, and Ehrlichia canis. In view of the One- Health concept, a regular monitoring of the spreading of these pathogens is necessary to give information of veterinary and human interest
Rickettsiosi del cane: considerazioni sui risultati di sierodiagnosi condotte su cani sintomatici.
In Italy, during the last years, rickettsiae of the Spotted Fever Group (SFG), other than Rickettsia conorii, have been detected and some human clinical cases have been related to them. During a ten years period, from 2003 to 2012, sera of 3196 pet dogs were tested for antibodies to R. conorii and R. rickettsii antigens, employing the indirect immunofluorescent antibody test. All serodiagnosis had been requested by veterinarians for dogs with symptoms reportable to rickettsiosis (lymphoadenomegaly, anorexia, lethargy, fever). One hundred and sixty (5.0%) animals resulted positive to R. conorii, 603 (18.86%) to R. rickettsii, 36 (1.12%) reacted to both antigens; the total number of dogs positive to Rickettsia spp. was 763 (23.87%). Considering that R. rickettsii has never been isolated in Italy and the rest of Europe, the seropositive reactions are probably due to other SFG species which are here circulating. Further studies should be carried out to verify the pathogenicity of these agents for dogs

Bacterial zoonoses among domestic reptiles
SUMMARY In the last years an ever-increasing importation of exotic animals destined to live under domestic conditions has been observed. Chelonians, terrestrial and aquatic turtles, are the most commonly present in domestic environment, even if saurians (lizards) and ophidians (snakes) are frequently kept in houses. Reptiles, that can be considered new pet animals, even if clinically healthy, often harbor opportunistic pathogens, which can become cause of serious infections under stress condition. Viral, protozoal, fungal and parasitic agents can infect the cold-blooded animals, but bacteria are the most common pathogens recovered from these animals and in most cases they can be transmitted to humans. Domestic reptiles represent an emerging problem for the public health. New reptile owners should be educated about a proper animal care in order to assure the pet health, to protect themselves from venomous or aggressive species, and to avoid the risk of infection. The main bacterial infections, transmitted from reptiles to humans, are reported, with particular attention to salmonellosis, mycobacteriosis, chlamydophilosis and Aeromonas and Pseudomonas infections. RIASSUNTO Negli ultimi anni si è assistito ad una notevole crescita del numero degli animali esotici destinati a vivere in ambiente domestico. I cheloni, tartarughe di terra e di acqua dolce, sono i più numerosi, ma i sauri e i serpenti sono tenuti come animali domestici con sempre maggiore frequenza. I rettili, anche se clinicamente sani, spesso albergano microrganismi patogeni opportunisti che possono divenire causa di serie patologie durante periodi di stress. Gli animali a sangue freddo sono colpiti da virus, protozoi, funghi, parassiti, ma sono i batteri i microrganismi più frequentemente isolati da soggetti con o senza patologie clinicamente manifeste. Molti di questi batteri sono in grado di causare infezione anche nell’uomo e per questo motivo i rettili domestici devono essere considerati un problema emergente per la sanità pubblica. I nuovi proprietari dovrebbero quindi essere opportunamente educati sui rischi che corrono tenendo i rettili nelle loro case, legati non solo a graffi e morsi talora velenosi, ma anche alle infezioni. Di seguito vengono trattate le principali zoonosi ad eziologia batterica trasmissibili dai rettili all’uomo, con particolare attenzione alle infezioni sostenute da salmonelle, micobatteri, clamidie, Aeromonas e Pseudomonas
