Ixodes ricinus infesting snakes: Insights on a new tick-host association in a Borrelia burgdorferi sensu lato endemic area.

Ixodes ricinus infesting snakes: Insights on a new tick-host association in a Borrelia burgdorferi sensu lato endemic area. Acta Trop. 2019 Feb 19;: Authors: Mendoza-Roldan JA, Colella V Abstract The castor bean tick Ixodes ricinus is one of the most abundant tick species in Europe, being able to parasitize a wide number of vertebrate hosts, including mammals, birds, and reptiles. This tick species has an important role as vector of zoonotic pathogens, including the causative agents of Lyme borreliosis (i.e. Borrelia burgdorferi sensu lato). Here, we provide insights on a new tick-host association (i.e. I. ricinus infesting snakes) in an area recently recognized as endemic for reptile-associated zoonotic species of Borrelia burgdorferi s.l..

In this study, cases submitted with a serologically confirmed, clinically unequivocal, or highly suspicious diagnosis of ECM/Lyme disease between January 01, 2016, and September 01, 2018, were retrieved from the electronic database system and reviewed to delineate the histopathologic features of ECM. The series consisted of 14 cases. A superficial perivascular lymphocytic infiltrate was noted in all biopsies, accompanied by a deep and/or interstitial inflammatory infiltrate in 9 cases (64%). The inflammation ranged from relatively sparse to dense and prominent. At least focal interface changes were noted in 12 biopsies (86...

Conclusions: Direct exposure to armadillos does not appear to be required for transmission of HD making a soil-mediated mechanism of indirect exposure plausible.

irkland Approximately 60% of Australia’s beef cattle are located in the vast rangelands of northern Australia. Despite the often low stocking densities and extensive management practices of the observed herd, animal prevalence of BVDV infection and typical rates of transmission are similar to those observed in intensively managed herds in southern Australia and elsewhere in the world. A recent large three- to four-year study of factors affecting the reproductive performance of breeding herds in this region found that where there was evidence of widespread and/or recent BVDV infection, the percentage of lactat...

During the fourteenth century, the bubonic plague or Black Death killed over one-third of Europe or 25 million people. Afflicted subjects died quickly and horribly from an unseen menace, spiking high fevers with suppurative buboes (swellings). Its causative agent is Yersinia pestis, creating recurrent plague cycles from the Bronze Age into modern-day California and Mongolia. Plague remains endemic in Madagascar, Congo, and Peru. This history of medicine review highlights plague events across the centuries.

In this study, the major factors underlying synonymous codon‐related amino acid usage in the B. burgdorferi genome and bias in synonymous codon usage of the translation initiation region of coding sequences were analyzed. Additionally, adaptation of B. burgdorferi to several of its hosts was analyzed in the context of synonymous codon usage. Principal component analysis (PCA) revealed that nucleotide content at the third synonymous position of a codon influenced the synonymous codon usage pattern, but the strand‐specific factor did not influence the synonymous codon usage pattern of B. burgdorferi. In terms of the low ...

Conclusion: Our results highlight the potential for climate change to have an effect on future Lyme disease risk in Canada even if the Paris Agreement’s goal to keep global warming below 2°C is achieved, although mitigation reducing emissions from RCP8.5 levels to those of RCP6.0 or less would be expected to slow tick invasion after the 2030s. https://doi.org/10.1289/EHP57 Received: 02 March 2016 Revised: 26 August 2016 Accepted: 30 August 2016 Published: 31 May 2017 Address correspondence to H.

Summary The spirochaete (Borrelia burgdorferi) associated with Lyme disease was detected in questing ticks and rodents during a period of 18 years, 1991–2009, at five locations on the Outer Banks of North Carolina. The black‐legged tick (Ixodes scapularis) was collected at varied intervals between 1991 and 2009 and examined for B. burgdorferi. The white‐footed mouse (Peromyscus leucopus), house mouse (Mus musculus) marsh rice rat (Oryzomys palustris), marsh rabbit (Sylvilagus palustris), eastern cottontail (Sylvilagus floridanus) and six‐lined racerunner (Cnemidophorus sexlineatus) were live‐trapped...

Conclusions: These results emphasize the need for follow-up investigations to determine whether the identified spatial pattern is due to: clustering of misdiagnosed cases, clustering of patients with an out-of state travel history, or presence of a clustered unknown enzootic cycle of B. burgdorferi in Texas. This would enable an improved surveillance and reporting of LD in Texas.
