Norovirus in captive lion cub (Panthera leo)
2007
African lions (Panthera leo) are susceptible to viral diseases of domestic carnivores, including feline calici-virus infection. We report the identification of a novel enteric calicivirus, genetically related to human noroviruses of genogroup IV, in a lion cub that died of severe hemorrhagic enteritis.
The effects of Borrelia infection on its wintering rodent host
2022
AbstractIn seasonal environments, appropriate adaptations are crucial for organisms to maximize their fitness. For instance, in many species, the immune function has been noticed to decrease during winter, which is assumed to be an adaptation to the season’s limited food availability. Consequences of an infection on the health and survival of the host organism could thus be more severe in winter than in summer. Here, we experimentally investigated the effect of a zoonotic, endemic pathogen, Borrelia afzelii infection on the survival and body condition in its host, the bank vole (Myodes glareolus), during late autumn–early winter under semi-natural field conditions in 11 large outdoor enclos…
Escherichia coli of human and avian origin: detection of clonal groups associated with fluoroquinolone and multidrug resistance in Italy
2012
Objectives: Poultry have been suggested as a reservoir for fluoroquinolone-resistant extraintestinal pathogenic Escherichia coli (ExPEC). Our aim was to investigate whether genotypes associated with ciprofloxacin and multidrug resistance were shared among human and avian E. coli. Methods: We compared 277 human ExPEC isolates from urinary tract infection (UTI) and sepsis (142 susceptible and 135 ciprofloxacin resistant) and 101 avian isolates (68 susceptible and 33 ciprofloxacin resistant) by antimicrobial resistance phenotype, phylogenetic group and multilocus sequence type (ST). Results: Most ciprofloxacin-resistant isolates from both human and avian sources were multidrug resistant. Human…
High prevalence of Blastocystis sp. in pigs reared under intensive growing systems: Frequency of ribotypes and associated risk factors
2007
Three hundred and ninety-five pig fecal samples were analyzed looking for Blastocystis sp. using optical microscopy and PCR. A global prevalence of 46.8% has been observed in this study, although relative values of prevalence differ notably according to the strata examined, ranging from 9.3% in sows to 75% in weaners. Statistic analysis of the data included several risk factors such as different management systems, date of sample collection, fecal consistency, age and sex of the animals. The presence of the parasite was statistically associated to the variables "age" and "date of sample collection", being more prevalent in weaners and grower pigs and warm season. Random fragment-length poly…
Toxoplasma gondii seroprevalence in extensively farmed wild boars (Sus scrofa) in Denmark
2019
Toxoplasma gondii is a zoonotic parasite of worldwide importance. In this study, we estimated T. gondii seroprevalence in extensively farmed wild boars in Denmark, where little is known about T. gondii in animal hosts. Our study focused on wild boars because they are considered good indicator species for the presence of T. gondii, and wild boar meat is used for human consumption. Serum samples from 101 wild boars collected in 2016-2018 from five different locations from the continental part of Denmark, Jutland, were screened for anti-T. gondii antibodies. The samples were analysed using a commercial indirect enzyme-linked immunosorbent assay (ELISA). Samples from 28 (27.7%) of the 101 wild …
The management of abdominal hydatidosis after the rupture of a pancreatic hydatid cyst: a case report
2015
Introduction Echinococcosis or hydatidosis is a zoonosis caused by cestodes from the genus Echinococcus; its habitat is the small intestine of the definitive host, represented by dogs/carnivorous animals, where it produces eggs which are eliminated in the environment. Cystic echinococcosis represents more than 95% of the hydatidosis cases registered annually. The most frequent localization is the hepatic one, followed by the pulmonary localization with a ratio of 2.5:1. A pancreatic localization represents 0.2% of hydatidosis cases with a higher possibility of disseminating intra-abdominally. The incidence of hydatidosis in Romania has not been investigated yet through national studies. Cas…
Ear, nose and throat (ENT) involvement in zoonotic diseases: a systematic review.
2013
Introducción: Las zoonosis son infecciones de transmisión del animal al hombre, ya sea directamente (a través del contacto directo o contacto con productos de origen animal) o indirectamente (a través de un vector intermedio, tal como un artrópodo). Los agentes causales incluyen bacterias, parásitos, virus y hongos. El propósito de esta revisión es hacer un examen preciso de todas las enfermedades zoonóticas que pueden ser responsables de oído, nariz y garganta (ENT) participación. Metodología: Se realizó una búsqueda en PubMed combinando los términos (otorrinolaringología o Rinología o laringología o otología or mastoiditis u otitis o sinusitis o laringitis o rinitis o faringitis o de la e…
Epidemiology of Q fever in Italy and in other Mediterranean countries
1987
Abstract The history of Q fever in Italy may be divided into three periods: epidemic in character after the Second World War, endemic occurrence from 1960 to 1980, and sporadic occurrence at present. Clinical symptoms are unspecific, and diagnosis must be confirmed by serology and isolation of the causative agent. The reported incidence is consequently underestimated. Results are reported of a seroepidemiologic survey in animals and humans in the Italian region and western Sicily. In the Mediterranean area several epidemic foci are still present. The need of further studies to evaluate the incidence of Q fever and to shed more light upon the epidemiology of Coxiella burnetii infections is s…

First case of Mediterranean spotted fever-associated rhabdomyolysis leading to fatal acute renal failure and encephalitis
2014
SummaryMediterranean spotted fever (MSF) is a tick-borne zoonosis caused by Rickettsia conorii. In Italy, about 400 cases are reported every year and nearly half of them occur in Sicily, which is one of the most endemic regions. Although MSF is mostly a self-limited disease characterized by fever, skin rash, and a dark eschar at the site of the tick bite called a ‘tache noire’, serious complications are described, mainly in adult patients. Nevertheless, severe forms of the disease with major morbidity and a higher mortality risk have been described. We report a fatal case of MSF complicated by rhabdomyolysis, acute renal failure, and encephalitis in an elderly woman.
