The prevalence and diversity of ticks on wildlife species on Guam is understudied, as to date no work has been conducted on the infection of these ticks with Rickettsia (obligate intracellular pathogens that use a variety of ectoparasites as vectors and can cause disease in humans, domestic animals, and wildlife species). The goal of our study was to investigate the presence of Rickettsia species on the island of Guam by testing ticks found on Philippine deer (Rusa marianna) and wild pigs (Sus scrofa). Increasing numbers of these species have led to increased interactions with humans, including hunting, highlighting the importance of studies on vector prevalence and associated zoonotic pathogens.

Effects of supramolecular complexation of praziquantel with disodium glycyrrhizinate on the liver fluke Opisthorchis felineus: An in vitro and in vivo study.

Acta Trop 2019 Mar 11;194:1-12. Epub 2019 Mar 11.

Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (SB RAS), Novosibirsk, Russia. Electronic address:

Millions of people worldwide have a chronic infection with the liver fluke Opisthorchis felineus, which causes opisthorchiasis in humans and animals. The only known effective drug for this disease is praziquantel (PrzQ); however, its efficacy is below 100%, and it has some adverse effects. In this study, a water-soluble complex of PrzQ with a disodium salt of glycyrrhizic acid (disodium glycyrrhizinate; NaGA) in a 1:10 ratio (PrzQ:GA) allowed the PrzQ dose to be decreased 11-fold for effective killing of O.

Contextualizing Schistosoma haematobium transmission in Ghana: Assessment of diagnostic techniques and individual and community water-related risk factors.

Acta Trop 2019 Mar 11;194:195-203. Epub 2019 Mar 11.

Tufts University School of Engineering, Medford, MA, USA; Tufts University, Friedman School of Nutrition Science and Policy, Boston, MA, USA.

Objectives: The study assessed associations between Schistosoma haematobium infection (presence of parasite eggs in urine or hematuria) and self-reported metrics (macrohematuria, fetching surface water, or swimming) to evaluate their performance as proxies of infection in presence of regular preventive chemotherapy. It also examined community water characteristics (safe water access, surface water access, and groundwater quality) to provide context for schistosomiasis transmission in different types of communities and propose interventions.

Methods: Logistic regression was used to assess the associations between the various measured and self-reported metrics in a sample of 897 primary school children in 30 rural Ghanaian communities. Read More
