In this study, twenty water samples were collected in the island of Lanzarote, Canary Islands, Spain in order to check for the presence of V. vermiformis strains in these samples. Water samples were cultured on 2% Non-Nutrient Agar (NNA) plates covered with a thin layer of heat killed E. coli and checked daily for the presence of Vermamoeba. After a week, V. vermiformis amoebae were observed in 2 of the 20 processed samples (10%) incubated at room temperature and 37°C. Molecular characterization was carried out by amplifying the 18S rDNA gene and DNA sequencing in order to confirm the identity of the isolated amoebic strains...

Adenosine deaminase (ADA) which degrades adenosine to inosine, is known to be pro-inflammatory molecule in many diseases. Adenosine suppresses the functioning of the immune system and thus promotes dissemination of the parasite. In our previous finding, the level of soluble ADA in serum of visceral leishmaniasis (VL) was found to be increased as compared to healthy controls. However, it cannot be fairly interpreted unless their level is demonstrated at the disease site, where the parasite resides. We designed this study to correlate the level of soluble ADA (sADA) with parasitic load at the disease site i...

A new feather mite species, Trouessartia sechellarum sp. n. (Astigmata: Analgoidea: Trouessartiidae), is described from the Seychelles magpie-robin Copsychus sechellarum (Passeriformes: Muscicapidae), an endangered endemic passerine bird inhabiting the Seychelles Islands. The most clear features distinguishing this mite from the related species, T. microfolia Gaud, 1952, are as follows: in both sexes, setae c2 do not exceed 30 μm and are subequal in length to setae c3 and sRIII; in males, the hysteronotal shield is completely split into the prohysteronotal and lobar parts by a narrow groove, and the terminal lamellae are attenuate apically; in females, the median part of the hysteronotal shield bears numerous ovate lacunae, the terminal cleft width is approximately equal to the opisthosomal lobe width, and the collar of the spermathecal head is smooth...

Acanthocotyle urolophi sp. nov. is described from the skin of the banded stingaree, Urolophus cruciatus (Lacépède, 1804). This is the first acanthocotylid to be described from Australian waters. Acanthocotyle urolophi sp. nov. is distinguished from other species of Acanthocotyle by a combination of the number of vitelline follicles 38 (33-46) and the number of rows 35 (32-37) of sclerites on the pseudohaptor. In addition, Acanthocotyle urolophi sp. nov. has no germarial appendix and no uterine "arm". A uterine receptaculum seminis was not identified in whole mounts...

Diseases caused by parasitic helminths cause considerable production and economic losses in livestock worldwide. Understanding the epidemiology of these parasites has important implications for controlling them. The main purpose of the present study was to estimate the prevalence of key parasitic helminths in goats along the Han River in Zhanggang, Hubei Province (from January to December 2014). We used faecal flotation and sedimentation techniques as well as PCR-based DNA sequencing to detect and identify helminths...

Three species of Isorchis Durio and Manter, 1969 are described from Australian waters. Isorchis megas sp. nov. is described from the spotbanded scat, Selenotoca multifasciata (Richardson), off Western Australia (WA) and Northern Territory (NT); Isorchis currani sp. nov. is described from S. multifasciata off NT; and Isorchis anomalus sp. nov. is described from the milkfish, Chanos chanos Forsskål, off WA. Isorchis megas sp. nov. can be differentiated from the other species of Isorchis by possessing a single, large egg that is greater than 20% of the body length; having a shorter body (the largest specimen is less than 500 μm); and utilizing a scatophagid rather than a chanid host...

This study brings the data about the occurrence of bacterial and protozoan pathogens in 32 great cormorants (Phalacrocorax carbo sinensis), representing approximately 20% of the population nesting in the surroundings of water basin Liptovská Mara (northern part of Central Slovakia). A survey revealed the presence of tick-borne bacteria Anaplasma phagocytophilum (6.25%) and parasitic protozoa Toxoplasma gondii (3.1%). These data indicate an infectious status of the great cormorant population nesting in Slovakia; they might suggest a degree of environmental contamination by infectious agents and demonstrate the role of migratory seabirds in the circulation and dispersal of pathogens with zoonotic potential...

About 3.6 million Pashtun and over 1.5 million immigrants from Afghanistan live in the federally administered tribal areas (FATA) on the border between Pakistan's Khyber Pakhtunkhwa Province and southern Afghanistan. Although malaria cases are common in FATA, no detailed studies have yet been performed to reveal the actual status of malaria in the local population and epidemiological data are insufficient to elucidate the actual incidence. A malariometric survey of 691 patients of all ages and genders in seven agencies (districts) in FATA was carried out in 2013 using whole blood samples...
