Newly collected specimens of 21 of the tetraphyllidean species were used to generate ssrDNA sequences that were combined with sequences previously available, including those of two diphyllidean taxa used for outgroup rooting. The sequences were aligned by eye according to secondary structural motifs of the conserved core of the molecule. Of the 1520 sites in the alignment, 874 (58%) were excluded from analysis due to alignment gaps and lack of positional homology as inferred by manual inspection. Genetic variability of the ssrDNA gene regions compared was greater than would be expected, based on the present taxonomy of the ingroup species, and the genetic divergences among tetraphyllidean `families' and genera were comparable to that among tapeworm orders. Phylogenetic hypotheses were generated by the methods of maximum parsimony and maximum likelihood (GTR + I + G nucleotide substitution model). -

Ecology and Evolutionary Biology
Ecology and evolutionary biology SPRING/SUMMER NEWSLETTER 2019 NUMBER 34 CARL SCHLICHTING RETURNS TO FULL TIME TEACHING AND RESEARCH On June 30, 2019 Dr. Carl Schlichting returned to full time teaching and research responsibilities after serving as EEB’s Department Head for 5 1/2 years (2014-2019). Carl received his B.S. in Zoology from Ohio State University, M.A. in Ecology and Evolution from SUNY at Stony Brook, and a Ph.D. in Botany from the University of Texas (Austin). Carl joined the EEB Department in 1988 as Assistant Professor at the Hartford campus. In 2000 he was promoted to Professor and joined the faculty in Storrs in 2002. He is looking forward to finishing some manuscripts and analyzing some old (Phox and Lobelia) and new (Pelargonium) datasets that have been awaiting his attention! During Carl’s tenure as Head, EEB welcomed eight new faculty members, six at Storrs and one each at Hartford and Stamford. Although he takes little credit, he notes that Department grant expenditures have risen by 40% to $3.5M/ year, and the number of EEB majors has risen from 55 to 80. Carl performed day-to-day management of the multi- year planning process for EEB’s eventual move into a newly renovated Gant Building, as well as the negotiations for a new Greenhouse facility. He will continue to manage the planning and move into EEB’s new Gant space. The exact dates of the two-phase moves will be announced in an upcoming newsletter so stay tuned. Faculty, students and staff are grateful to Carl for his leadership and support during his tenure as Department Head. -

Pentastomiasis in Australian Re
Fact sheet Pentastomiasis (also known as Porocephalosis) is a disease caused by infection with pentastomids. Pentastomids are endoparasites of vertebrates, maturing primarily in the respiratory system of carnivorous reptiles (90% of all pentastomid species), but also in toads, birds and mammals. Pentastomids have zoonotic potential although no human cases have been reported in Australia. These parasites have an indirect life cycle involving one or more intermediate host. They may be distinguished from other parasite taxa by the presence of four hooks surrounding their mouth, which they use for attaching to respiratory tissue to feed on host blood. Pentastomid infections are often asymptomatic, but adult and larval pentastomids can cause severe pathology resulting in the death of their intermediate and definitive hosts, usually via obstruction of airways or secondary bacterial and/or fungal infections. Pentastomiasis in reptiles is caused by endoparasitic metazoans of the subclass Pentastomida. Four genera are known to infect crocodiles in Australia: Alofia, Leiperia, Sebekia, and Selfia; all in the family Sebekidae. Three genera infect lizards in Australia: Raillietiella (Family: Raillietiellidae), Waddycephalus (Family: Sambonidae) and Elenia (Family: Sambonidae). Four genera infect snakes in Australia: Waddycephalus, Parasambonia (Family: Sambonidae), Raillietiella and Armillifer (Family: Armilliferidae). Definitive hosts Many species of Australian reptiles, including snakes, lizards and crocodiles are proven definitive hosts for pentastomes (see Appendix 1). Lizards may be both intermediate and definitive hosts for pentastomids. Raillietiella spp. occurs primarily in small to medium-sized lizards and Elenia australis infects large varanids. Nymphs of Waddycephalus in several lizard species likely reflect incidental infection; it is possible that lizards are an intermediate host for Waddycephalus. -

Although it is understood that short-term T. suis infectioninpeoplewithsuchdiseases usually induces a modified Th2-immune response, nothing is known about the molecules in the parasite that induce this response. Methodology/Principal Findings: As a first step toward filling the gaps in our knowledge of the molecular biology of T. suis, we characterised the transcriptome of the adult stage of this nematode employing next-generation sequencing and bioinformatic techniques. A total of ,65,000,000 reads were generated and assembled into -

The organism has been studied for decades in the laboratory, and Genetic diversity its colonization of laboratory rats has recently been shown as protective against some inflammation-associated Helminth-therapy disorders. Recently, H. diminuta has become a leading candidate for helminth therapy, an emerging method of Laboratory isolates “biota enrichment” used to treat or prevent inflammatory diseases of humans in Western society. While most of the experimental isolates of H. diminuta are identified based on typical morphological features, hymenolepidid tapeworms may represent complexes of cryptic species as detected by molecular sequence data. -
Armillifer Armillatus Elective Neutering

In April 2010, a male stray dog, 6 months of age, was admitted to the veterinary clinic for Armillifer armillatus elective neutering. Coiled pentastomid larvae were found in the vaginal processes of the testes during surgery. Adult Ova at Snake Farm, and larval parasite specimens were preserved in 100% The Gambia, West Africa Dennis Tappe, Michael Meyer, Anett Oesterlein, Assan Jaye, Matthias Frosch, Christoph Schoen, and Nikola Pantchev Visceral pentastomiasis caused by Armillifer armillatus larvae was diagnosed in 2 dogs in The Gambia. Parasites were subjected to PCR; phylogenetic analysis confi rmed re- latedness with branchiurans/crustaceans. Our investigation highlights transmission of infective A. armillatus ova to dogs and, by serologic evidence, also to 1 human, demonstrating a public health concern. entastomes are an unusual group of vermiform para- Psites that infect humans and animals. Phylogenetically, these parasites represent modifi ed crustaceans probably re- lated to maxillopoda/branchiurans (1). Most documented human infections are caused by members of the species Armillifer armillatus, which cause visceral pentastomiasis in West and Central Africa (2–4). An increasing number of infections are reported from these regions (5–7). Close contact with snake excretions, such as in python tribal to- temism in Africa (5) and tropical snake farming (2), as well as consumption of undercooked contaminated snake meat (8), likely plays a major role in transmission of pentastome ova to humans. The Study In May 2009, a 7-year-old female dog was admitted to a veterinary clinic in Bijilo, The Gambia, for elective ovariohysterectomy. -

Trichuriasis Importance Trichuriasis Is Caused by Various Species of Trichuris, Nematode Parasites Also Known As Whipworms
Trichuriasis Importance Trichuriasis is caused by various species of Trichuris, nematode parasites also known as whipworms. Whipworms are common in the intestinal tracts of mammals, Trichocephaliasis, although their prevalence may be low in some host species or regions. Infections are Trichocephalosis, often asymptomatic; however, some individuals develop diarrhea, and more serious Whipworm Infestation effects, including dysentery, intestinal bleeding and anemia, are possible if the worm burden is high or the individual is particularly susceptible. T. trichiura is the species of whipworm normally found in humans. A few clinical cases have been attributed to Last Updated: January 2019 T. vulpis, a whipworm of canids, and T. suis, which normally infects pigs. While such zoonotic infections are generally thought uncommon, recent surveys found T. suis or T. vulpis eggs in a significant number of human fecal samples in some countries. T. suis is also being investigated in human clinical trials as a therapeutic agent for various autoimmune and allergic diseases. The rationale for its use is the correlation between an increased incidence of these conditions and reduced levels of exposure to parasites among people in developed countries. There is relatively little information about cross-species transmission of Trichuris spp. in animals. However, the eggs of T. trichiura have been detected in the feces of some pigs, dogs and cats in tropical areas with poor sanitation, raising the possibility of reverse zoonoses. One double-blind, placebo-controlled study investigated T. vulpis for therapeutic use in dogs with atopic dermatitis, but no significant effects were found. Etiology Trichuriasis is caused by members of the genus Trichuris, nematode parasites in the family Trichuridae. -
Neglected Tropical Diseases in The
Qian et al. Infectious Diseases of Poverty (2019) 8:86 https://doi.org/10.1186/s40249-019-0599-4 SCOPING REVIEW Open Access Neglected tropical diseases in the People’s Republic of China: progress towards elimination Men-Bao Qian1, Jin Chen1, Robert Bergquist2, Zhong-Jie Li3, Shi-Zhu Li1, Ning Xiao1, Jürg Utzinger4,5 and Xiao-Nong Zhou1* Abstract Since the founding of the People’s Republic of China in 1949, considerable progress has been made in the control and elimination of the country’s initial set of 11 neglected tropical diseases. Indeed, elimination as a public health problem has been declared for lymphatic filariasis in 2007 and for trachoma in 2015. The remaining numbers of people affected by soil-transmitted helminth infection, clonorchiasis, taeniasis, and echinococcosis in 2015 were 29.1 million, 6.0 million, 366 200, and 166 100, respectively. In 2017, after more than 60 years of uninterrupted, multifaceted schistosomiasis control, has seen the number of cases dwindling from more than 10 million to 37 600. Meanwhile, about 6000 dengue cases are reported, while the incidence of leishmaniasis, leprosy, and rabies are down at 600 or fewer per year. Sustained social and economic development, going hand-in-hand with improvement of water, sanitation, and hygiene provide the foundation for continued progress, while rigorous surveillance and specific public health responses will consolidate achievements and shape the elimination agenda. Targets for poverty elimination and strategic plans and intervention packages post-2020 are important opportunities for further control and elimination, when remaining challenges call for sustainable efforts.
