Candida pararugosa isolation from the oral cavity of an Italian denture wearer

2004

Candida pararugosa was first isolated from human feces, but after the initial description no further recovery from humans has been reported. During a study on oral Candida colonization in denture wearers living in Palermo (Italy), we isolated C. pararugosa from a 61-year-old woman without signs of oral candidosis. This constitutes, to the authors' knowledge, the first isolation of C. pararugosa from the oral cavity. After six months, colonization by C. pararugosa persisted, suggesting that this species could be a component of the normal oral microbiota. The identification procedure we used could be useful in elucidating the epidemiology of C. pararugosa and for establishing its clinical sig…

Detection of the norovirus variants GGII.4 hunter and GGIIb/hilversum in Italian children with gastroenteritis.

2006

Noroviruses (NoVs) are important enteric pathogens of humans. Although they exhibit an impressive genetic diversity, few NoV strains appear to predominate worldwide. Limited epidemiological data are available on NoV gastroenteritis in Italy. In this study, we assessed the prevalence of human NoV in Italian children with gastroenteritis by using a reverse-transcription nested polymerase chain reaction (RT-PCR) assay specific for the RNA-dependent RNA polymerase (RdRp) on faecal samples collected throughout the 2004 surveillance activity in Palermo, Italy. NoVs were detected in 47% of the stool samples obtained from children <5 years age, admitted to hospital with acute non-bacterial gastroen…

Nationwide surveillance study of human astrovirus infections in an Italian paediatric population

2012

SUMMARYThe study investigated the genetic diversity of human astroviruses (HAstVs) detected in children hospitalized with gastroenteritis in Italy in 2008–2009. A total of 1321 faecal samples were collected in Parma (northern Italy), Bari (southern Italy), and Palermo (Sicily) and screened for the presence of HAstVs. RT–PCR amplification of a portion at the 5′-end of ORF2 allowed the detection of HAstVs in 3·95% of the patients. Four different genotypes (HAstV-1, HAstV-2, HAstV-4, HAstV-5) were found to be circulating during the study period, with HAstV-1 being the predominant type. Interestingly, a novel lineage, proposed as HAstV-2d, was found to have emerged in Parma in 2009. Investigati…

First report of Antigastra catalaunalis on sesame in Greece.

2017

Τον Αύγουστο του 2016, καταγράφηκαν σοβαρές προσβολές σε καλλιέργειες σουσαμιού από το έντομο Antigastra catalaunalis (Duponchel) (Lepidoptera: Crambidae) σε αγροτικές περιοχές της Περιφερειακής Ενότητας Δράμας. Το A. catalaunalis είναι ένας σημαντικός εχθρός της καλλιέργειας του σουσαμιού σε περιοχές όπου αυτό καλλιεργείται. Παρατηρήθηκαν συμπτώματα προσβολής από τις προνύμφες του εντόμου σε φύλλα, βλαστούς και κάψες. Οι προσβολές καταγράφηκαν σε όλους τους αγρούς με καλλιέργεια σουσαμιού που επιθεωρήθηκαν, με επίπεδα προσβολής υψηλά τα οποία προκάλεσαν οικονομική απώλεια. Στο βαθμό που γνωρίζουμε, αυτή είναι η πρώτη αναφορά σοβαρών προσβολών σουσαμιού από το Α. catalaunalis στην Ελλάδα.

Prevalence of Mycobacterium bovis in agroecosystems : analysis of potential environmental reservoirs (soil, fresh water, soil fauna and aquatic fauna…

2016

Bovine tuberculosis is an infectious disease caused by Mycobacterium bovis. This disease affects cattle, and many species of domestic and wild mammals, and humans. The circulation of the bacteria in various multi-host systems promotes the maintenance of the disease and the contamination of cattle in the vicinity. Beside direct transmission of the bacteria through the respiratory route, indirect transmission, through inhalation or ingestion of environmental matrices contaminated by an infected animal excretory, is suspected in several countries. Environmental contamination with M. bovis appears to be a crucial factor in the persistence of the infection in multi-host systems.In Côte d'Or, a F…

Morphology of Bertiella studeri (Blanchard, 1891) sensu Stunkard (1940) (Cestoda: Anoplocephalidae) of human origin and a proposal of criteria for th…

2000

Human material of an African specimen of Bertiella studeri (Blanchard, 1891), a typical intestinal cestode of monkeys, is described. Mature, postmature and gravid proglottides, and eggs, previously inadequately figured, are illustrated and photographed. The description of the species agrees with that provided by Stunkard (1940). A comparative study with other descriptions of the species is made in an attempt to clarify previous findings. The morphological differences reported in various earlier descriptions of the species suggest that B. studeri should be regarded as a "B. studeri species complex". Improvements are required in the descriptions of new future findings in order to clarify the …

Methods for diagnosing bile acid malabsorption: a systematic review

2019

Abstract Background Bile acid malabsorption (BAM) and bile acid-related diarrhea represent an under-recognized cause of chronic diarrhea mainly because of limited guidance on appropriate diagnostic and laboratory tests. We aimed to perform a systematic review of the literature in order to identify and compare the diagnostic accuracy of different diagnostic methods for patients with BAM, despite a proven gold standard test is still lacking. Methods A PubMed literature review and a manual search were carried out. Relevant full papers, evaluating the diagnostic accuracy of different methods for BAM, were assessed. Available data were analyzed to estimate the sensitivity and specificity of each…

Role of tir and intimin in the virulence of rabbit enteropathogenic Escherichia coli serotype O103:H2.

2000

ABSTRACT Attaching and effacing (A/E) rabbit enteropathogenic Escherichia coli (REPEC) strains belonging to serogroup O103 are an important cause of diarrhea in weaned rabbits. Like human EPEC strains, they possess the locus of enterocyte effacement clustering the genes involved in the formation of the A/E lesions. In addition, pathogenic REPEC O103 strains produce an Esp-dependent but Eae (intimin)-independent alteration of the host cell cytoskeleton characterized by the formation of focal adhesion complexes and the reorganization of the actin cytoskeleton into bundles of stress fibers. To investigate the role of intimin and its translocated coreceptor (Tir) in the pathogenicity of REPEC, …
