    Transcriptomic Analysis of the Temporal Host Response to Skin

    Burgess et al. BMC Genomics 2010, 11:624 http://www.biomedcentral.com/1471-2164/11/624 RESEARCH ARTICLE Open Access Transcriptomic analysis of the temporal host response to skin infestation with the ectoparasitic mite Psoroptes ovis Stewart TG Burgess*, David Frew, Francesca Nunn, Craig A Watkins, Tom N McNeilly, Alasdair J Nisbet, John F Huntley Abstract Background: Infestation of ovine skin with the ectoparasitic mite Psoroptes ovis results in a rapid cutaneous immune response, leading to the crusted skin lesions characteristic of sheep scab. Little is known regarding the mechanisms by which such a profound inflammatory response is instigated and to identify novel vaccine and drug targets a better understanding of the host-parasite relationship is essential. The main objective of this study was to perform a combined network and pathway analysis of the in vivo skin response to infestation with P. ovis to gain a clearer understanding of the mechanisms and signalling pathways involved. Results: Infestation with P. ovis resulted in differential expression of 1,552 genes over a 24 hour time course. Clustering by peak gene expression enabled classification of genes into temporally related groupings. Network and pathway analysis of clusters identified key signalling pathways involved in the host response to infestation. The analysis implicated a number of genes with roles in allergy and inflammation, including pro-inflammatory cytokines (IL1A, IL1B, IL6, IL8 and TNF) and factors involved in immune cell activation and recruitment (SELE, SELL, SELP, ICAM1, CSF2, CSF3, CCL2 and CXCL2). The analysis also highlighted the influence of the transcription factors NF-kB and AP-1 in the early pro-inflammatory response, and demonstrated a bias towards a Th2 type immune response.

A sexually dimorphic ungulate of large stature and unique coloration, it is the only species in the genus Boselaphus. It is endemic to peninsular India and small parts of Pakistan and Nepal, has been extirpated from Bangladesh, and has been introduced in the United States (Texas), Mexico, South Africa, and Italy. It prefers open grassland and savannas and locally is a significant agricultural pest in India. It is not of special conservation concern and is well represented in zoos and private collections throughout the world. DOI: 10.1644/813.1.

    The Role of Wild and Domestic Ungulates in Forming the Helminth Fauna of European Bison in Belarus

    Sviatlana Polaz et al. European Bison Conservation Newsletter Vol 10 (2017) pp: 79–86 The role of wild and domestic ungulates in forming the helminth fauna of European bison in Belarus Sviatlana Polaz, Alena Anisimova, Palina Labanouskaya, Aksana Viarbitskaya, Vasili Kudzelich The State Research-Production Association “The Scientifically-Practical Centre of the National Academy of Sciences of Belarus for bio-resources”, Minsk, Belarus Abstract: Discussed is the role of wild and domestic ungulates in the formation of helminth fauna of the European bison in the Republic of Belarus. The current status of helminth infection of E. bison was determined and comparative analysis was conducted regarding the helminth fauna of other wild and domestic ungulates of the Republic of Belarus. Key words: European bison, helminth infection, Belarus Introduction The European bison (Bison bonasus) is a rare terrestrial mammal inhabiting a num- ber of countries including the territory of the Republic of Belarus. To facilitate fur- ther increase of its population, measures for conservation and sound management have been developed, aiming at preserving the already existing European bison population and enriching it with new individuals through an import of animals from other countries. One of present urgent problems in maintenance of European bison are parasitic infestations, since breeding programs carried out in Belarus concern not only the European bison but also other species of large mammals. Therefore an access to complete information about the types of helminths that are capable to affect the health of the E. bison and about factors that influence the formation of helmin- thiases is very important. One of these aspects is the transfer of helminths from one organism to another.

This study was undertaken to identify and characterize Amblyomma species ticks collected from cattle in Plateau State, North-Central, Nigeria. They were morphologically identified using diagnostic characters. Further confirmation and characterization was done genetically using a 460bp-long partial fragment of the 16S rRNA gene amplified by polymerase chain reaction (PCR). The amplified fragment was cloned and sequenced for the phylogenetic dendogram. All the examined ticks were identified as A. variegatum which was confirmed by 16S rRNA gene sequences analysis, and phylogenetic inferences showed a 99% similarity and grouping to A. variegatum of African origin. However, the A. variegatum sequences from Nigeria were clustered into 2 groups, but formed a distinct clade from the A. variegatum sequence from Ethiopia.

Received: 04/11/2017 Accepted: 14/12/2017 Abstract Most larvae of Erythraeidae are considered as parasites of various insect species, and their adults seem to be effective generalist predators of several agricultural pests. Studies of this fauna is limited in Syria. The present study aimed to identify mite species of Erythraeidae in a pesticide-free citrus orchard in Latakia governorate/Syria. Surveys were carried out three times in 2016 and 2017. Three Erythraeid species were collected, and all belong to the genus Erythraeus: Erythraeus (Erythraeus) phalangoides, Erythraeus (Erythraeus) adanaensis and Erythraeus (Zaracarus) didonae. This is the first report of these species in Syria. Morphological remarks of each species were collected and provided. Keywords: Acari, Erythraeidae, Erythraeus, larva, Syria Introduction Recent advances in knowledge of mite fauna in Syrian agro-ecosystems are took place. Actually, the number of reported species from Syria increased from about 15 species in 2012 to more than 80 species in 2017 (Zriki et al., 2015; Barbar, 2016, 2017; Zeity, 2017; Barbar and Ueckermann, 2017), and more species still to be discovered. The family Erythraeidae presently comprises more than 300 nominal species (Gerson et al., 2009; Krantz and Walter, 2009). Most larvae of these mites are parasites of various arthropods, but adults have been shown to be effective generalist predators of several agricultural pests including insects and spider mites (Zhang, 2003; Gerson et al., 2009).

Its distribution and prevalence in developed nations has been curtailed by various successfully implemented preventive health measures and geographic conditions. In few low and middle income nations, pulmonary parasitic infections still remain a problem, although not rampant. With increase in immunocompromised patients in these regions, there has been an upsurge in parasites isolated and reported in the recent past.

Hoang Quoc Viet Rd, Cau Giay, Hanoi, Vietnam, email: [email protected] ; 2. Nguyen Thi Lan Anh, National Institute of Veterinary Research, 86 Truong Chinh, Hanoi, Vietnam, email: [email protected] We report, for the first time, the occurrence of Toxocara malaysiensis, but not T. cati in domesticated cats in Vietnam; and T. canis was commonly found to infect dogs. The finding of T. malaysiensis infection is likely of public health concern and warrants investigations of this ascaridoid in Vietnam and other countries. -------------------------------------------------------------------------------------------------------------------- Toxocariasis is a globally distributed infection of carnivores, primarily dogs and cats caused by species of the Toxocara genus (Nematoda: Toxocaridae), including Toxocara canis, T. cati and T. malaysiensis (McGuinness, Leder, 2014). T. canis and T. cati in pets are of the significant zonootic ascaridoid nematodes infecting humans reported worldwide (Moreira et al., 2014; Fisher, 2003), while the recently described species, T. malaysiensis (Gibbons et al., 2001), contributes less prevalence in cats and humans (Macpherson, 2013).
