RESUMO
Human babesiosis is an emerging zoonotic disease; diffused especially in some regions of the United States, it has been less frequently observed in other continents, including Europe. Serological surveys suggest that babesiosis could be more frequent than expected in European countries, representing an emerging health-issue and a possible harm, especially in immunocompromised populations. Only one case of human babesiosis has been reported in Italy and data about the diffusion of the pathogen in this country are scant. We conducted a multicentric serological survey in 5 centers of North-Eastern Italy, aimed to detect the seroprevalence of Babesia spp. antibodies in 3 groups of immunocompromised patients: people living with HIV (PLHIV), rheumatologic patients undergoing immunosuppressive therapies and patients undergoing renal transplant. Among the 433 enrolled patients, 3 (0.7%) tested positive for Babesia spp. serology. All positive patients belonged to the PLHIV group, with a seroprevalence of 1.7% (3/180) in this population; the three serologically positive patients were all asymptomatic. They were all enrolled in the provinces of Bolzano and Trento, where seroprevalences of 3.1% and 3.6% were recorded, respectively. Our results suggest that further research is needed on this field, awareness should be raised toward the human disease in Europe, especially in immunocompromised patients, and this emerging health issue should be analyzed in a One-Health perspective to be fully understood.
RESUMO
Antimicrobial resistance (AMR) is one of the most complex global health challenges today: decades of overuse and misuse in human medicine, animal health, agriculture, and dispersion into the environment have produced the dire consequence of infections to become progressively untreatable. Infection control and prevention (IPC) procedures, the reduction of overuse, and the misuse of antimicrobials in human and veterinary medicine are the cornerstones required to prevent the spreading of resistant bacteria. Purified drinking water and strongly improved sanitation even in remote areas would prevent the pollution from inadequate treatment of industrial, residential, and farm waste, as all these situations are expanding the resistome in the environment. The One Health concept addresses the interconnected relationships between human, animal, and environmental health as a whole: several countries and international agencies have now included a One Health Approach within their action plans to address AMR. Improved antimicrobial usage, coupled with regulation and policy, as well as integrated surveillance, infection control and prevention, along with antimicrobial stewardship, sanitation, and animal husbandry should all be integrated parts of any new action plan targeted to tackle AMR on the Earth. Since AMR is found in bacteria from humans, animals, and in the environment, we briefly summarize herein the current concepts of One Health as a global challenge to enable the continued use of antibiotics.
RESUMO
We determined the seroprevalence of hepatitis E virus (HEV) in persons in 2 rural communities in southeastern Bolivia and the presence of HEV in human and swine fecal samples. HEV seroprevalence was 6.3%, and HEV genotype 3 strains with high sequence homology were detected.
