TL;DR: The status of acaricide resistance in cattle ticks from different parts of the world is summarized and modes of action of currently used acaricides, mechanism of resistance development, contributory factors for the development and spread of resistance, management of resistant strains and strategies to prolong the effect of the available acar pesticides are reviewed.

TL;DR: The results showed here demonstrated the first case of fluazuron resistance in R. microplus and the first tick population resistant to six classes of acaricides in Brazil.

TL;DR: There are presently no reports that definitively link anthelmintic resistance with clinical problems in horses, but that generally appears to be due to a publication bias toward well managed horse farms and the lack of appropriate diagnostic methods for rapidly quantifying anthel Mintic resistance in these parasites.

TL;DR: Dose ranging and a 5-month multi-dose experimental study in dogs, established that the 2.5mg/kg oral dosage was highly effective against fleas and ticks, and produced predictable and reproducible pharmacokinetics following repeated dosing.

TL;DR: It appears likely that pigs are natural hosts of Blastocystis with a high prevalence of ST5 that is presumably the pig-adapted ST in these regions, and close contact between pigs and their handlers may increase the risks of zoonotic transmission.

TL;DR: The cattle and equine industries have, until quite recently, remained generally oblivious to the issue of anthelmintic resistance and the need to take pre-emptive action, indicating a failure to learn the lessons from resistance development in small ruminants.

TL;DR: Xenodiagnostic studies carried out with wild rabbits captured in the area demonstrate that they are able to transmit L. infantum to P. perniciosus, suggesting that wild rabbits could play some role in Leishmania transmission.

TL;DR: This study was undertaken in two different climatic areas of Turkey to determine the presence of tick-borne pathogens of medical and veterinary importance and found most tick pools were infected with a single pathogen.

TL;DR: Current knowledge on the global epidemiology, geographical distribution and genotype frequency of Echinococcus spp.

TL;DR: The results of the present study indicate the high efficacy of treatment with oral formulations of MOX and IVM on all farms, except on 1 farm in Greece, where multi drug resistance (MDR) was identified involving 4 anthelmintics.

TL;DR: Current information on Troglostrongylus spp.

TL;DR: Cod or seal worm Pseudoterranova decipiens was recorded in musculature associated with a negative correlation between worm intensity and condition factor and infection with Anisakis simplex in Baltic cod was found at a low level corresponding to previous studies.

TL;DR: The challenges ahead include the development of programs that control the anthelmintic resistant nematodes but at the same time result in more sustainable parasite control, and whether it is important that parasite control programs are sustainable over time, or if the pharmaceutical industry develop new control agents at a rate sufficient to render sustainability unimportant.

TL;DR: The present results suggest that the interactions between tannins and other PSC are complex and may reduce the AH effects against H. contortus eggs.

TL;DR: The results of this study indicate that multiple vector-borne pathogens responsible for severe diseases infect dogs in Costa Rica and therefore, increased owner and veterinarian awareness are needed.

TL;DR: A review of current evidence with equine and ruminant parasites suggests that fitness is not significantly compromised in drug resistant strains, and the need for further research is emphasized.

TL;DR: Although its sensitivity is not ideal yet, discarding the IFA and including the DPP improved the accuracy of the new Brazilian CVL diagnostic protocol, particularly of detecting truly infected dogs.

TL;DR: There is a great need for new and improved methods for diagnosis and surveillance to supplement or replace the fecal egg counts, and equine health parameters need to be included in studies evaluating any parasite control program.

TL;DR: This pattern of contamination strongly supports the role of inhabited areas which concentrate cat populations as sources of risk for oocyst-induced infection for both humans and animals and suggests a large spatial scale of environmental contamination, which could result from T. gondii oocysts dissemination through rain washing or other mechanisms.

TL;DR: The qPCR technique developed here allowed us to quantify environmental E. multilocularis contamination by fox faeces by studying the infectious agent directly and no previous study had performed this test in a one-step reaction.

TL;DR: Nanoencapsulated EcEO did not obtain the expected efficacy in vivo and was not effective on the control of gastrointestinal nematodes of small ruminants in vitro and in vivo.

TL;DR: It is highlighted that pooling ovine faecal samples is a rapid procedure that holds promise as a valid strategy for assessing GI strongyles FEC and FECR in sheep.

TL;DR: The widespread distribution of Theileria spp.

TL;DR: Even though recommendations for standardized fecal flotation procedures have been promoted in the past, it is clear that the factors are too numerous to allow for the recommendation of one, or even a few, procedures for all purposes.

TL;DR: The pharmacokinetic properties of afoxolaner are suited for a monthly administration product because the fast absorption and long terminal half-life support a rapid onset of action while ensuring month-long efficacy.

TL;DR: The prevalence of the infection by L. infantum in the study population was 41% and did not differ between group A and B cats, and the likelihood of PCR-positivity was higher than in group A cats, thus highlighting the need for multiple tissue PCR testing in order to minimize false-negative results.

TL;DR: The results showed that there is an association of genotypes of ROP5 and ROP18 with mouse-virulence, however, additional gene(s) may also contribute to virulence in distinct T. gondii genotypes.

TL;DR: Dried, pelleted SL has excellent potential as a natural anti-coccidial feed for weaned goats and should be considered for use in the treatment of internal parasites, including gastrointestinal nematodes.

TL;DR: A multiplex PCR-based method was developed to overcome the limitations of microscopic examination as a means of identifying individual infective larvae from the wide range of strongylid parasite species commonly encountered in sheep in mixed sheep-cattle grazing situations in New Zealand.

TL;DR: Investigation of dairy farms in England and Wales found birds and rodents may represent significant reservoirs of Cryptosporidium due to high prevalence, large oocyst concentrations, and the detection of a C. parvum subtype known to be present in human populations, identified in samples from these wildlife.
