Zoonotic Dirofilaria immitis and Dirofilaria repens infection in humans and an integrative approach to the diagnosis
2021
Abstract Dirofilariosis by Dirofilaria immitis and Dirofilaria repens is endemic in dogs from countries of the Mediterranean basin. Both species may infect humans, with most of the infected patients remaining asymptomatic. Based on the recent description of the southernmost hyperendemic European focus of heartworm disease in dogs from the Pelagie archipelagos, we performed a serological and molecular survey in human population of that area. Human blood samples were collected in the islands of Linosa (n=101) and Lampedusa (n=296) and tested by ELISA and molecular test for the detection of D. immitis and D. repens. Samples were also screened for filarioid-associated endosymbionts, Wolbachia s…
Secondary hemophagocytic lymphohistiocytosis in zoonoses. A systematic review
2012
BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a rare syndrome that is often fatal despite treatment. It is caused by a dysregulation in natural killer T-cell function, resulting in activation and proliferation of histiocytes with uncontrolled hemophagocytosis and cytokines overproduction. The syndrome is characterized by fever, hepatosplenomegaly, cytopenias, liver dysfunction, and hyperferritinemia. HLH can be either primary, with a genetic aetiology, or secondary, associated with malignancies, autoimmune diseases, or infections. AIM: To focus on secondary HLH complicating zoonotic diseases. MATERIALS AND METHODS: PubMed search of human cases of HLH occurring during zoonotic dise…
The Immunology of Zoonotic Infections
2012
Zoonotic infections are in general defined as infections transmitted from animal to man (and less frequently vice versa), either directly (through contact or contact with animal products) or indirectly (through an intermediate vector as an arthropod or an insect) [1]. Although the burden of zoonotic infections worldwide is major, both in terms of immediate and long-term morbidity and mortality [2, 3] and in terms of emergence/reemergence and socioeconomical, ecological, and political correlations [4], scientific and public health interest and funding for these diseases remain relatively minor. Zoonoses include diseases induced by diverse pathogens (bacteria, viruses, fungi, and parasites), …
Further spread of West Nile virus in Italy.
2010
Following two consecutive years of West Nile virus (WNV) circulation in Italy, new foci of infection were observed in August 2010 in Sicily and Molise in southern and central Italy, respectively. These incidents were far from the previous infected area in northern Italy, thereby confirming the ability of WNV to spread to new areas and affect new host populations. © Istituto G. Caporale 2010.
Epidemiology and management of foodborne nematodiasis in the European Union, systematic review 2000–2016
2018
Background: Foodborne nematodiasis are caused by the ingestion of food contaminated by helminths. In Europe, these diseases are present in all countries. Objectives: To review the available data on epidemiology and management of foodborne nematodiasis in the European Union, detect any trends and determine the possible causes of the observed changes. Methods: A review of available literature published between 2000 and 2016 was conducted. Results: Out of 1523 cases described in the literature, 1493 cases were autochthonous and 30 cases were imported. The detected parasites were Toxocara spp (34.7%), Ascaris lumbricoides (27.1%), Trichinella spp (21.9%), Anisakis spp (15.5%) and Angiostrongylu…
Trends in the Epidemiology of Leishmaniasis in the City of Barcelona (1996–2019)
2021
Background: Leishmaniasis is a neglected zoonosis produced by 20 different flagellated parasites of the Leishmania genus, a protozoan transmitted to humans and other vertebrates by the bite of dipteran insects of the Phlebotominae subfamily. It is endemic in Mediterranean countries and the number of cases is expected to increase due to climate change and migration. Prioritizing public health interventions for prevention and control is essential. The objective was to characterize the epidemiology and temporal trends in the incidence of human leishmaniasis in the city of Barcelona, between the years 1996 and 2019. Methods: A population-based, analytical observational study among residents in …
Alveolar echinococcosis: characteristics of a possible emergence and new perspectives in epidemiosurveillance
2001
International audience; The aim of this review is to discuss the situation of alveolar echinococcosis in France, in the light of the current knowledge on its transmission patterns in the world, especially Europe. An important risk of higher contamination of the rural environment may be suspected from newly reported cases of infected foxes or voles in several countries where the disease was not found before. Furthermore, the increase of prevalence rate in foxes in Bade-Würtemberg (Germany) and Franche-Comté (France), traditionally endemic, is also in support of this new trend. Urban foxes and the spreading of infected foxes to cities may also be the cause of the extension to urban and suburb…
Genomic epidemiology: from transmission to the evolution of pathogenic microorganisms
2022
La epidemiología genómica ha revolucionado el mundo microbiano. Sus aplicaciones permiten conocer y comprender mejor el comportamiento, la transmisión y la evolución de los microorganismos. A pesar de su gran y reconocido potencial, su uso aún es limitado, especialmente en regiones en desarrollo. El principal objetivo de esta tesis fue estudiar y analizar los genomas completos de tres microorganismos patógenos y zoonóticos para comprender mejor su epidemiología, potencial patogénico y evolución. En el primer capítulo caracterizamos a nivel genómico a Salmonella enterica aislada de alimentos, fincas y muestras clínicas en Ecuador. Además, presentamos evidencia de la presencia de factores de …
