Cecere, Fernando Spina, Federica MonacoAbstractThe continuous flow of billions of birds between Africa and Europe creates an “ecological bridge” between physically remote areas. Migratory birds fly south from their breeding grounds during late summer/fall and fly back in spring. These movements regulate the spread of internal and external parasites, as well as pathogens of potential public health concern. The aim of the present study was to investigate the possible introduction of exotic tick species and tick-borne pathogens into Europe via migratory birds. At the bird observatory of Ventotene island (Italy), 443 feeding ticks were collected from 249 birds captured and ringed during their northbound migration in spring 2013. Each tick was identified by morphological and molecular methods and then tested for bacterial and viral pathogens: Borrelia burgdorferi s.l., Rickettsia spp., Ehrlichia ruminantium and Coxiella burnetii, Crimean Congo haemorrhagic fever virus (CCHFV) and Flavivirus. Morphological and molecular identification confirmed Hyalomma rufipes as the most abundant species among the collected arthropods (366/443; 82.6%) followed by Hyalomma marginatum (10/433; 2.3%). Rickett...

Talib, Choon Hui Tan, Khalina Abdan, Eric Wei Chiang ChanAbstractNano adsorbent possess notable adsorption capabilities but is difficult to recover in wastewater treatment processes. To overcome this limitation, the entrapment of nanocellulose (NCC) and chitosan (Cts) within poly(hydroxyalkanoate) (PHA) via electrospinning is proposed. The Pickering emulsion stabilized with Tween 80 formed a homogeneous NCC-Cts-PHA mixture prior to electrospinning. ...

We describe a new fish blood fluke (Digenea: Aporocotylidae: Electrovermis zappum n. gen., n. sp.) and its life cycle in the intertidal zone adjacent to Mobile Bay (north-central Gulf of Mexico). This is the first elucidated aporocotylid life cycle that includes a chondrichthyan definitive host or a bivalve intermediate host. The new species undergoes asexual reproduction within the gonad of the variable coquina clam before maturing in the heart of the lesser electric ray. These adults and cercariae had identical 28S, 18S, and ITS2 nucleotide sequences. The new genus is similar to Ogawaia Cutmor et al., 2018 by having an i...

CONCLUSION: The current study indicates that knee muscle strength variables, resulting from an isokinetic testing, have the potential to discriminate between soccer players with and without a history of low back pain. However, low back pain is a multidimensional phenomenon and knee muscle strength or imbalance alone cannot be expected to explain low back pain. PMID: 31524139 [PubMed - as supplied by publisher]

Due to its conservation status in Portugal, i.e. endangered, it is important to understand the role of parasites in this population, since they can be a limiting factor for the population fitness and trophic interactions and, ultimately, their survival. From November 2017 to August 2018, 33 fre...

To reduce infection-associated morbidity, WHO has published guidelines for control of schistosomiasis based on targeted mass drug administration (MDA) and, in 2017, on supplemental snail control. We compared the current WHO guideline-based strategies from 2012 to an alternative, adaptive decision making framework for control in heterogeneous environments, to estimate their pre...

In this study, we used high-throughput genotyping by sequencing to resolve the genetic structure of the Mediterranean ex situ lentil collection held at the Italian National Research Council. Sequencing of a 188-plex genotyping-by-sequencing library and bioinformatics treatment of data yielded 6,693 single nucleotide polymorphisms. Analysis of nonredundant genotypes with nonparametric and parametric methods highlighted the occurrence of five highly differentiated genetic clusters. Clustering could be related to geographic patterns and phenotypic traits, indicating that post-domestication routes introducing cultivation in Me...

ConclusionsThe unusual presentation of Familial Mediterranean Fever with liver disease suggests the role of inflammasome in hepatic inflammation. Colchicine controls systemic inflammation in most of the patients; however, subclinical inflammation can persist in some of them and can manifest with increased levels of CRP, ESR, serum amyloid A also in attack-free intervals.
