Tick-Borne Diseases - Science topic

Theileriosis is a tick borne disease recorded in ruminants. Besides causing anemia it affects the respiratory tract thereby causing pulmonary oedema.

Dear Collegues,

Are you interested in Medical and Veterinary Entomology as well as Global Health?

An Entomology Summer School, entitled “Hands on’ Course on Arthropods of Medical and Veterinary Significance: A global perspective, from theory to practice”, will be held from the 26th till the 30th of August 2019 at the National Vet School of Toulouse (ENVT), France.

Please find the complete programme leaflet attached to this message.

The course will encompass topics such as arthropod-borne diseases, resistance in arthropod populations, control tools, principles of laboratory rearing and morphological identification of arthropods of medical and veterinary importance (i.e. mosquitoes, flies, sand flies, fleas, ticks, mites, etc.).

The course targets entomologists, postgraduate students in this field, , post-doctoral scientists ACVM and EVPC residents, pest control professionals and the like.

Applications to attend will be accepted until the 31st of March.

See you in Toulouse?!

That is a frequent question concerning Ixodes ricinus asked by public. And there are two groups of parasitologists answering - the ones who say "maybe" and the others who say "have some doubts". Is there anybody aware of studies solving this issue? Experimental evidence wanted!!!

There is an urgent need for Bartonella-specific antigens for use in gauging effector and memory T-cell responses. I am looking for a reputable source from anywhere.

In Lyme disease research, routinely vector tick(I. ricinus) is pressed and its hemolymph could be search for B. burgdorferi under dark field microscopy.

To start of I am trying to isolate DNA from blood and ticks for the identification of the tick species and a parasite that is transmitted by the ticks, by running it through agarose gel, and a limited budget.

To be clear about this question, I get no DNA from Rhipicephalus decloratus ticks when using the Kapa Express Extract kit that can extract DNA from insects. I have followed the instructions to the letter. The only unclear thing in the instructions is that i should spin at high speed for 1 min.

Can anyone please help me by telling me perhaps at what speed this is(rpm or xg).

Alternatively if someone has experience with this kit and ticks please provide me with a few pointers or alterations to the protocol to get the maximum amount of DNA (dilution is a possibility afterwords) 

And please remember that this is before the PCR is performed (which does not work due to no DNA).

I need a contacts!

I have started a Questionnaire Survey across few villages in the fringe zone of a Protected Area (PA) to gather information on prevalence of tick-borne zoonotic diseases. I would like to know the methods of determining the sample size for my study so that I can design a robust framework for the same. Why is 20% of the population regarded in some studies as an ideal sample size?

With regards

.

Dear Researchers,

Is there any publication about this issue?

There has been extensive work published on tick-borne diseases in the Indian sub-continent, mostly from the Veterinary Science sector. But I am in need of a descriptive survey on the prevalence, status and distribution of tick species reported in North-eastern India for my PhD work. 

Thanks

i had collected this ticks on the brown hare, i know that those parasites are rhipicephalus but please if you can confirm me the species.

these ticks are collected from wild rabbits please anyone can confirm me their species.

I am looking for a researcher working on Babesiosis to collaborate with, in order to detect IgG antibodies on human and bovine serum samples from Colombia. Any suggestion?

I am looking for experimental evidence (or convincing non-experimental evidence) that the number of fleas or ticks an individual animal harbors is related to that individual's risk of infection by a vector-borne pathogen.  Can anyone point me to some compelling literature?

Theileria camelensis, piroplasma spp., babesia spp. have been recovered from blood of dromedaries and Bactrian but they are non-pathogenic. Old world camels contrary to cattle and small stock seems not to be affected by serious tick-borne diseases such as East Coast Fever, Piroplasmosis, Anaplasmosis

Why does the alpha-Gal allergy affect some people and not others - is it caused by reaction to tick saliva/enzyme or is it a tick borne disease transmitted to humans or is there a genetic cause/immune system?

Kyasanur Forest disease (KFD) is caused by Kyasanur Forest disease virus (KFDV), a member of the virus family Flaviviridae.

I need update keys for differentiation of D. marginatus from D. niveus?

Does it mean that yellow ticks have only taken up plasma? Will such ticks moult successfully? I want to know the mechanism behind this phenomenon.

Please see below picture.

I want to buy a GPS device to be used for vector mapping in Sudan and low income countries.

I want new information on the diagnosis of Hyalomma marginatum from H. detritum. . Can anyone help me?

Is there any data available indicating tick infestation and reduced reproduction in domestic animals or in any animal species?

I have DNA from babesia bovis and bigemina from clinical and non clinical cases.

I am a Phd student and I want to work on a hard ticks survey and their tick born diseases in the Mazandaran provinces in Iran.

I am looking into a large number of samples of deer and wild rodents. The tick borne pathogens, inside each genus, are too similar to differentiate and cloning will increase the number of samples greatly. I have been using primers for Ehrlichia, Anaplasma, Babesia and Theileria species but these primers are not specific and they cross reacted with other strains. In turn, the sequencing of the nested PCR positive samples failed (may be due to coinfection with multiple pathogens which were picked up with the same primer). I am thinking of switching to RLB but I don't know how sensitive and specific this method is in comparison to the nested PCR, cloning and sequencing.
