Tick-borne pathogens in Ixodes ricinus ticks collected from migratory birds in southern Norway
2020
Birds are important hosts for the first life stages of the Ixodes ricinus tick and they can transport their parasites over long distances. The aim of this study was to investigate the prevalence of Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum, Neoehrlichia mikurensis and Rickettsia helvetica in ticks collected from migratory birds in Norway. A total of 815 Ixodes ricinus ticks from 216 birds trapped at Lista Bird Observatory in southern Norway during spring and autumn migration in 2008 were analysed by real-time PCR. B. burgdorferi s. l. was the most prevalent pathogen, detected in 6.1% of the ticks. The prevalence of N. mikurensis, A. phagocytophilum and R. helvetica was 1.2%…
A link between ectoparasite infection and susceptibility to bacterial disease in rainbow trout
2006
Rainbow trout, Oncorhynchus mykiss, were infected concomitantly with Argulus coregoni and Flavobacterium columnare and their survival was compared with that of fish infected with either the parasite or the bacterium alone. The mortality of fish challenged with A. coregoni was negligible while infection with F. columnare alone led to significantly lower survival. However, compared with single infections, the mortality was significantly higher and the onset of disease condition was earlier among fish, which were concomitantly infected by A. coregoni and F. columnare. This data presents, for the first time, experimental support for the hypothesis that an ectoparasite infection increases suscep…
OLIVE FRUIT FLY: A threat to the South African olive industry?
2015
Olive fruit fly (Bactrocera oleae) is the most serious pest of cultivated olives in the Mediterranean basin. to date we have not seen the same level of damage in south africa, but the question remained whether it poses a similar threat as the local olive industry expands. From this study it is clear that the climatic con- ditions during the period preceding harvest are un- favourable for rapid population growth of OFF in the Western Cape, in contrast to conditions in the coastal area of Trapani province in Sicily. Climate, and not parasitism, appears to be the main factor limiting OFF population levels in the Western Cape. While sporadic outbreaks of economically damaging OFF infestations c…
Essential versus accessory aspects of cell death: recommendations of the NCCD 2015
2015
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ?accidental cell death' (ACD). In most settings, however, cell death is initiated by a genetically encoded apparatus, correlating with the fact that its course can be altered by pharmacologic or genetic interventions. "Regulated cell death" (RCD) can occur as part of physiologic programs or can be activated once adaptive responses to perturbations of the extracellular or intracellular microenvironment fail. The biochemical phenomena that accompany RCD may be harnessed to…
Holistic and unified approach to facilitate graphical data visualization and statistical predictive modelling for diseases at the microorganism level
2015
Borrelia species are predominantly responsible for the most common form of Tick-borne diseases (TBD) which is Lyme borreliosis (LB). Episodes of Lyme arthritis (LA) is a hallmark symptom of LB patients. LA is an atypical form of reactive arthritis (ReA) that is a sub-type of Spondyloarthritis (SpA). Coinfections such as Ehrlichia chaffeensis accompany primary Borrelia species during the later stages of LB infection to induce severe symptoms. Currently, there is no holistic approach that would unify different TBD pathogens into independent and multiple TBD infection (MTBDI) combination categories to facilitate graphical and statistical analysis between any two patients groups. The chronic ma…
Ordinare il tempo. Sui principi organizzativi dei calendari cerimoniali
2016
Le rappresentazioni del tempo e dello spazio variamente declinate nella storia dall’homo religiosus, in quanto riduzioni e tra- duzioni culturali dell’unicum continuum spazio- temporale in esperienze umanamente concepibili, si riflettono e si esibiscono con particolare evidenza – oltre che nelle credenze, nei miti, nell’organizzazione dei sistemi sociali, ecc. – nelle attività rituali che sostanziano le feste religiose. Questo può osservarsi tanto a livello della loro distribuzione calendariale quanto a livello della strutturazione degli specifici itinera festivi e dei relativi contenuti simbolici. Le feste, infatti, agite in tempi e spazi definiti, da un lato disgiungono, perimetrando e co…
Angelo Brelich, Introduzione allo studio dei calendari festivi
2015
Tra le costanti che determinano la formazione e la trasformazione del pensiero calendariale e – più in generale degli orientamenti delle varie religioni – emergono i modi di reperimento delle risorse alimentari. Sono i tempi dell’accesso a queste risorse, correlati ai ritmi della natura e alle forme della produzione, che condizionano, ab origine, il primo strutturarsi del tempo festivo e dell’organizzazione sociale: «vi è un’interdipendenza funzionale tra le forme dell’esistenza economico-sociale e le forme culturali umane» (Brelich 1955:, I, 63). Nelle società preistoriche, antiche e “primitive”, tanto in quelle di cacciatori-raccoglitori quanto in quelle agro-pastorali, sono innanzitutto …

Oral Manifestations of Wolf-Hirschhorn Syndrome: Genotype-Phenotype Correlation Analysis
2020
Background: Wolf-Hirschhorn syndrome (WHS) is a rare disease caused by deletion in the distal moiety of the short arm of chromosome 4. The objectives of this study were to report the most representative oral findings of WHS, relate them with other clinical characteristics of the disease, and establish possible phenotype-genotype correlation. Methods: The study was conducted at 6 reference centers distributed throughout Spain during 2018&ndash
