Ticks and tick-borne diseases.

Ticks and tick-borne diseases. Med Mal Infect. 2019 Feb 05;: Authors: Boulanger N, Boyer P, Talagrand-Reboul E, Hansmann Y Abstract Ticks are a major group of arthropod vectors, characterized by the diversity of pathogens they transmit, by their impact on human and animal health, and by their socioeconomic implication especially in countries of the Southern Hemisphere. In Europe, Ixodes is the most important tick due to its wide distribution in the ecosystems and the variety of transmitted pathogens, in particular Borrelia (responsible for Lyme borreliosis), but also the tick-borne encephalitis virus. Their increased presence in the environment since the beginning of the 20th century is undeniable, because of major modifications in the biodiversity caused by humans. Increasing the awareness of health professionals and the general population is required to achieve better control of these infections. Thus, "a better understanding of these tick-borne diseases for a better control" is a simple but effective approach, considering their ubiquity in the environment and their particular mode of pathogen transmission (long-lasting blood meal for hard ticks and delayed transmission for bacteria and parasites). Finally, these ectoparasites are problematic due to the potential allergic reactions and other damages caused by their saliva, in humans and animals.

NielsenAbstractA model was developed to reproduce the dynamics of the parasitic stages of equine cyathostomins. Based on a detailed review of published literature, a deterministic simulation model was constructed using the escalator box-train approach, which allows for fully-overlapping cohorts of worms and approximately normally distributed variations in age/size classes. Key biological features include a declining establishment of ingested infective stage larv...

Kate Winslet picture about renowned fossil hunter had been criticised by relatives for ‘unconfirmed’ portrait of her sexualityThe director of a new biopic about the celebrated fossil hunter Mary Anning has defended his film after criticism of its lesbian romance storyline.Ammonite, which stars Kate Winslet and Saoirse Ronan, recently began filming in Lyme Regis, the coastal town in Dorset where Anning lived in the early 19th century. Anning never married and is not known to have had any direct descendants, but a report in the Telegraph suggested her distant relatives were at odds over the film ’s central ...

Abstract Eukaryotic cells have different mechanisms of post-transcriptional regulation. Among these mechanisms, microRNAs promote regulation of targets by cleavage or degradation of the mRNA. Fungi of the Paracoccidioides complex are the etiological agents of the main systemic mycosis of Latin America. These fungi present a plasticity to adapt and survive in different conditions, and the presence of microRNAs-like molecules could be part of the mechanisms that provide such plasticity. MicroRNAs produced by the host influence the progression of this mycosis in the lungs besides regulating targets involved in apoptosis in ma...

In this study, the prevalence of antibodies against two Babesia spp. was investigated in a cohort of patients that were seropositive for Borrelia (B.) burgdorferi sensu lato (s.l.). Data were compared to a control group of healthy individuals. Sera were collected from 283 individuals residing in the southernmost region of Sweden, Skåne County. Almost one third of the sera were from patients with a confirmed seropositive reaction against B. burgdorferi s.l. All sera samples were assessed for IgG antibodies against Babesia (Ba.) microti and Ba. divergens by indirect fluorescent antibody (IFA) assays. Seropositive IgG t...

Ticks and the diseases they carry have long been recognized as health concerns, especially in the warmer months when ticks (and humans) are more active. Ticks wait on grass tips or shrubs to latch onto new hosts when they brush by. Most of the hosts are animals, but a few tick species do bite and feed on humans. While doing so, they can transmit bacteria and viruses through their saliva. But here’s what’s changing: Tick species are being found in a wider geographic range. The number of case reports of tick-borne illnesses is increasing. Scientists continue to identify new pathogens (bacteria and viruses that c...
