The impact of vector control on the prevalence of Theileria cervi in farmed Florida white-tailed deer, Odocoileus virginianus

Vector-borne diseases exert a global economic impact to the livestock industry. Understanding how agriculture practices and acaricide usage affect the ecology of these diseases is important for making informed...

Publication date: Available online 21 August 2019Source: Ticks and Tick-borne DiseasesAuthor(s): R. Megía-Palma, D. Paranjpe, P. Blaimont, R. Cooper, B. SinervoAbstractIt is generally accepted that parasites exert negative effects on their hosts and that natural selection favors specific host responses that mitigate this impact. It is also known that some components of the host immune system often co-evolve with parasite antigens resulting in a host-parasite arms race. In addition to immunological components of the anti-parasitic response, host behavioral responses are also important in this arms race and natural se...

Three-year review says new vaccines for eradicating disease are only 40% effectiveMalaria will not be eradicated in the foreseeable future even though it is achievable and would save millions of lives, according to World Health Organization (WHO) experts following a three-year review.The WHO remains committed to the “disappearance of every single malaria parasite from the face of the planet”, as it has been since the UN organisation was launched in 1948, said Dr Pedro Alonso, the director of its global malaria programme.Continue reading...

The objective was to evaluate the potential of Fluorescence in Situ Hybridization as a diagnostic method for Cutaneous leishmaniasis in Sri Lanka. Literature on current laboratory tests used to diagnose Cutaneous leishmaniasis in Sri Lanka and globally was reviewed. Sri Lankan data were reviewed systematically following the PRISMA guidelines. A narrative of the results is presented. There is currently no gold standard diagnostic method for Cutaneous leishmaniasis. Fluorescence in Situ Hybridization has been previously applied to detect dermal pathologies including those involving infectious agents, and its use to detect th...

Pi uptake and transcription of LamPho84 gene are differentially regulated during parasite life cycle. Our data suggest that Pi acquisition could be a pivotal task for the success of the parasite throughout its life cycle.Graphical abstract

Till date, the polymorphic variant was considered predominant, constituting 85–90%. However, following active-case surveillance, the proportion of macula...

Tokarski, Abhay R. Satoskar, James R. Fuchs, Eric M. Bachelder, Kristy M. AinslieAbstractVisceral leishmaniasis (VL) is associated with treatment complications due to the continued growth of resistant parasites toward currently available pathogen-directed therapeutics. To limit the emergence and combat resistant parasites there is a need to develop new anti-leishmanial drugs and alternative treatment approaches, such as host-directed therape...

In the 19th century the word ‘virus’ was used to describe the cause of any contagious disease. How it came to describe the very small intracellular parasites that we know today is a fascinating story that illustrates our evolving concepts of infectious agents. Long before bacteria, fungi, and viruses were identified, it was known that […]

In conclusion, the results show that salmon were able to mount a robust adaptive response to different PAA doses and exposure times, and a combined exposure to stress and PAA. These results underscore the potential of PAA as a chemotherapeutant for salmon at PAA concentrations commonly applied to control parasitic infestations.

In conclusion, diclazuril is effective in attenuating Eimeria oocysts and thus provides an alternative approach for using diclazuril-treated oocysts to protect chicks against Eimeria challenge.

This study sought to evaluate spatial variation in encysted cyathostomin larval counts among the large intestinal organs and their subsections. Following humane euthanasia, ceca, ventral, and dorsal colons were harvested from 8 foals (aged 4-8 months) raised in an anthelmintic naïve parasitology research herd. Each organ was weighed and separated into 3 equal sections by length: the orad, intermediate, and aborad portions. From each of those sections, two 5% weight tissue samples were collected and digested to quantify the early third stage larvae (EL3) and late third stage larvae/fourth stage larvae (LL3/L4). A mixed...
