Combination Anthelmintic Treatment for Persistent Ancylostoma Caninum Ova Shedding in Greyhounds
CASE SERIES Combination Anthelmintic Treatment for Persistent Ancylostoma caninum Ova Shedding in Greyhounds Lindie B. Hess, BS, Laurie M. Millward, DVM, Adam Rudinsky DVM, Emily Vincent, BS, Antoinette Marsh, PhD ABSTRACT Ancylostoma caninum is a nematode of the canine gastrointestinal tract commonly referred to as hookworm. This study involved eight privately owned adult greyhounds presenting with persistent A. caninum ova shedding despite previous deworming treatments. The dogs received a combination treatment protocol comprising topical moxidectin, followed by pyrantel/febantel/praziquantel within 24 hr. At 7–10 days posttreatment, a fecal examination monitored for parasite ova. Dogs remained on the monthly combination treatment protocol until they ceased shedding detectable ova. The dogs then received only the monthly topical moxidectin maintenance treatment. The dogs remained in the study for 5–14 mo with periodical fecal examinations performed. During the study, three dogs reverted to positive fecal ova status, with two being associated with client noncompliance. Reinstitution of the combination treatment protocol resulted in no detectable ova. Use of monthly doses of combination pyrantel, febantel and moxidectin appears to be an effective treatment for nonresponsive or persistent A. caninum ova shedding. Follow-up fecal examinations were important for verifying the presence or absence of ova shedding despite the use of anthelmintic treatment. Limitations of the current study include small sample size, inclusion of only privately owned greyhounds, and client compliance with fecal collection and animal care.

Conservation and Diversification of Small RNA Pathways Within Flatworms Santiago Fontenla1, Gabriel Rinaldi2, Pablo Smircich1,3 and Jose F
Fontenla et al. BMC Evolutionary Biology (2017) 17:215 DOI 10.1186/s12862-017-1061-5 RESEARCH ARTICLE Open Access Conservation and diversification of small RNA pathways within flatworms Santiago Fontenla1, Gabriel Rinaldi2, Pablo Smircich1,3 and Jose F. Tort1* Abstract Background: Small non-coding RNAs, including miRNAs, and gene silencing mediated by RNA interference have been described in free-living and parasitic lineages of flatworms, but only few key factors of the small RNA pathways have been exhaustively investigated in a limited number of species. The availability of flatworm draft genomes and predicted proteomes allowed us to perform an extended survey of the genes involved in small non-coding RNA pathways in this phylum. Results: Overall, findings show that the small non-coding RNA pathways are conserved in all the analyzed flatworm linages; however notable peculiarities were identified. While Piwi genes are amplified in free-living worms they are completely absent in all parasitic species. Remarkably all flatworms share a specific Argonaute family (FL-Ago) that has been independently amplified in different lineages. Other key factors such as Dicer are also duplicated, with Dicer-2 showing structural differences between trematodes, cestodes and free-living flatworms. Similarly, a very divergent GW182 Argonaute interacting protein was identified in all flatworm linages. Contrasting to this, genes involved in the amplification of the RNAi interfering signal were detected only in the ancestral free living species Macrostomum lignano. We here described all the putative small RNA pathways present in both free living and parasitic flatworm lineages. Conclusion: These findings highlight innovations specifically evolved in platyhelminths presumably associated with novel mechanisms of gene expression regulation mediated by small RNA pathways that differ to what has been classically described in model organisms. -

Gupta Block, Kolkata 700 091 Post Graduate Department of Zoology, Vidyasagar College, Salt Lake City, CL N. Debnath Block, Kolkata 700 091 ABSTRACT The present paper reports the occurrence of 111 species of mites belonging to 69 genera,27 families under 3 orders collected from a total of 40 samples representing 5 different habitats viz. stored products, house dust, bird nests, cattle sheds and roof gardens from 5 districts of South Bengal. Among the 5 habitats, cattle shed provided richest diversity both in respect of species and genera followed by stored product habitat and the minimum was bird nest which represented only 11 species. The family level diversity was also highest in case of cattle sheds followed by stored products and the minimum was in roof garden. There was not a single species which could be collected from all the 5 habitats though; of course, there was 1 species which represented 4 out of 5 habitats. Therefore, cattle sheds proved to be habitat showing highest diversity. The order Prostigmata represented highest number of species followed by Astigmata. -

Leptotrombidium Deliense

R. China; 2Vector Laboratory, Institute of Pathogens and Vectors, Yunnan Provincial Key Laboratory for Zoonosis Control and Prevention, Dali University, Dali, Yunnan Province 671000, P. R. China Abstract: This article reviews Leptotrombidium deliense, including its discovery and nomenclature, morphological features and identification, life cycle, ecology, relationship with diseases, chromosomes and artificial cultivation. The first record of L. deliense was early in 1922 by Walch. Under the genus Leptotrombidium, there are many sibling species similar to L. de- liense, which makes it difficult to differentiate L. deliense from another sibling chigger mites, for example, L. rubellum. The life cycle of the mite (L. deliense) includes 7 stages: egg, deutovum (or prelarva), larva, nymphochrysalis, nymph, ima- gochrysalis and adult. The mite has a wide geographical distribution with low host specificity, and it often appears in differ- ent regions and habitats and on many species of hosts. As a vector species of chigger mite, L. deliense is of great impor- tance in transmitting scrub typhus (tsutsugamushi disease) in many parts of the world, especially in tropical regions of Southeast Asia. The seasonal fluctuation of the mite population varies in different geographical regions. The mite has been successfully cultured in the laboratory, facilitating research on its chromosomes, biochemistry and molecular biology. -

Hymenolepis Nana Is a Ubiquitous Parasite, Found Throughout Many Developing and Developed Countries
Characterisation of Community-Derived Hymenolepis Infections in Australia Marion G. Macnish BSc. (Medical Science) Hons Division of Veterinary and Biomedical Sciences Murdoch University Western Australia This thesis is presented for the degree of Doctor of Philosophy of Murdoch University 2001 I declare that this thesis is my own account of my research and contains as its main work which has not been submitted for a degree at any other educational institution. ………………………………………………. (Marion G. Macnish) Characterisation of Community-Derived Hymenolepis Infections in Australia ii Abstract Hymenolepis nana is a ubiquitous parasite, found throughout many developing and developed countries. Globally, the prevalence of H. nana is alarmingly high, with estimates of up to 75 million people infected. In Australia, the rates of infection have increased substantially in the last decade, from less than 20% in the early 1990’s to 55 - 60% in these same communities today. Our knowledge of the epidemiology of infection of H. nana is hampered by the confusion surrounding the host specificity and taxonomy of this parasite. The suggestion of the existence of two separate species, Hymenolepis nana von Siebold 1852 and Hymenolepis fraterna Stiles 1906, was first proposed at the beginning of the 20th century. Despite ongoing discussions in the subsequent years it remained unclear, some 90 years later, whether there were two distinct species, that are highly host specific, or whether they were simply the same species present in both rodent and human hosts. The ongoing controversy surrounding the taxonomy of H. nana has not yet been resolved and remains a point of difference between the taxonomic and medical literature.
