The epizootic of Bluetongue virus (BTV) throughout Europe in 2006 revealed insufficient knowledge regarding seasonal activities, endo/exophilic and endo/exophagic behaviour of the species of the Culicoides genus (Diptera: Ceratopogonidae). Although several studies have been carried out in Western Europe, bringing new knowledge of the above mentioned topics, there was still a gap to fill in Central Europe. Therefore, this study investigated seasonal variations in the indoor/outdoor Culicoides activity observed in the south-eastern Slovakia from 2012 to 2014, using a light-trapping method...

During an extensive survey of fish parasites along the Malabar coast of India we observed exceptionally high or even massive infection of the narrow-barred Spanish mackerel, Scomberomorus commerson (Scombridae), with parasitic copepods Cybicola armatus. Such infection has not hitherto been reported. The copepods occurred on the gills of its host and the infection persisted for many years (the survey lasted from January 2010 to July 2014). The overall prevalence was very high (95%); out of a total of 981 fish studied, 933 were infected, and the maximum intensity reached 42...

The abundance of elk (Alces alces) in Poland at the beginning of 2016 reached over 28 000 individual animals. However, little is still known about health status of elk population in the country. In particular, important health issue tend to be parasitic diseases which are the most common diseases in wild animals. Special emphasis should be given to the parasitofauna of elks. Their ability to move over great distances increases the chance of parasitic infestations in new areas and transmission to other wild animals and livestock...

Fascioliasis is a zoonosis actually considered as a foodborne trematode disease priority by the World Health Organization. Our study presents three cases of F. hepatica infection diagnosed by direct, indirect and/or imaging diagnostic techniques, showing the need of the combined use of them. In order to overcome some difficulties of the presently available methods we show for the first time the application of molecular tools to improve human fascioliasis diagnosis by employing a PCR protocol based on a repetitive element as target sequence...

Cutaneous leishmaniasis (CL) caused by Leishmania major is common in southern Israel, while Leishmania infantum (sub-strain of L. donovani, causing zoonotic visceral leishmaniasis) infections were rarely reported in Israel and only in other regions. We report the first case of L. infantum infection in southern Israel, presented atypically as CL in an immunosuppressed 47-year old male. The patient was treated with liposomal amphotericin-B and recovered, without extra-cutaneous complications. Diagnosis of L. infantum CL was confirmed by microscopic identification of amastigotes in Gimsa-stained smear of skin lesion, positive blood serology and a positive polymerase chain reaction (PCR) amplification of the internal transcribed spacer 1 genes (ITS1) and restriction fragment length polymorphism (ITS1 PCR-RFLP)...

There are few published studies on various vector borne diseases of dogs in India and most depict clinical infection in dogs, diagnosed by observation of the haemopathogens in stained blood smears. This study provides the first report regarding molecular confirmation and ancestral relationship analysis of blood smears positive cases of assorted haemopathogens in Punjab province of India. On blood smear examination, haemopathogens were observed in 124 out of 778 (15.95%, 95% CI: 13.53- 18.68) blood smears. Further polymerase chain reactions (PCR) was used on bloods smear positive cases to validate the results...

Free-living amoebae of Acanthamoeba genus are opportunistic pathogens distributed worldwide. Strains included in this genus are causative agents of a fatal encephalitis and a sight-threating keratitis in humans and other animals. In this study, 550 clinical samples which were collected between 1984 and 2014 from different patients with suspected infections due to Acanthamoeba were initially screened for the presence of this amoebic genus at the Laboratorio de Amibiasis-Escuela de Bioanálisis at the Universidad Central de Venezuela...

Pathogenic strains of Acanthamoeba are causative agents of a sight threating infection of the cornea known as Acanthamoeba keratitis. AK cases have been reported in Iran recently due to inappropriate usage of contact lens maintenance and most patients report a contact with contaminated sources such as dust, water or soil. Sixty soil samples were collected from public and recreational areas in the province of East Azerbaijan, Iran and checked for the presence of Acanthamoeba spp. Samples were cultured on non-nutrient agar plates seeded with heat killed Escherichia coli...

A phenomenon of switching of the parasite in the food chain to an accidental host is commonly observed in nature. However, there is little available data concerning the morphological descriptions of parasites that passively get into the atypical hosts and are capable, at least to some degree, of somatic growth and development of reproductive structures. A morphological survey of Diplodiscus subclavatus (Pallas, 1760) adults isolated from a digestive tract of an accidental host, Viviparus contectus (Millet, 1813), was carried out...

Theileriosis caused by Theileria lestoquardi (malignant ovine theileriosis) in sheep and Theileria annulata (tropical theileriosis) in cattle is an important hemoprotozoal tick-borne disease in Iran. Due to major biologic and phylogenic similarities of these two species, this study was carried out to investigate the occurrence of natural infections with T.lestoquardi and T.annulata in cattle with clinical theileriosis in Ahvaz, southwest Iran. Fifty one cattle were selected based on clinical signs of theileriosis and confirmation by microscopic examination of blood smears...

The pace of anti-malarial drug discovery is often impeded due to the lack of tools to determine the cidality of compounds in vitro. An anti-malarial compound must have a cidal mode of action, i.e. kill parasites, in order to quickly reduce parasite load. A static compound that merely inhibits growth must be identified early on in the discovery cascade. In this paper, we describe a high-throughput fluorescent assay for determination of the cidality of an anti-malarial compound. The assay works on the principle that cultures treated with a static compound will exhibit re-growth while treatment with a cidal compound leads to a marked reduction in parasite number...

Monocotyle luquei n. sp. (Monogenea: Monocotylidae) was described from gills of diamond stingray Dasyatis dipterura (Jordan and Gilbert, 1880) (Dasyatidae) off Peru. The new species can be differentiated from the other species of the genus by the combination of the following characteristics: (1) accessory sclerites on the dorsal posterior surface of the body absent, (2) only one testis is present, (3) 1-2 loops in the copulatory organ, (4) the male copulatory organ with a sclerotized accessory piece, (5) shape of five sclerites in marginal papillae, (6) size of anchor and (7) posterolateral septa bifurcated...

Digenetic trematodes have complex life cycles involving multiple hosts and free-living larval stages. Some species have 2 lar-val stages that infect snails, with miracidia and cercariae using these molluscs as first and second intermediate hosts, respec-tively. Although both larval stages may infect the same snail species, this is accomplished using different chemical cues and may be influenced by different biotic and abiotic factors. Significant differences in the infection patterns of these parasitic stages regarding host size and density were observed in 2 separate field studies...

Parasites are ubiquitous members of biotic communities. To investigate the infective status of helminth parasites in Pelophylax nigromaculatus from Shanghai, 90 frogs were collected from July 2013 to July 2014 and examined for the presence of internal parasites. Of these, 86.67% (78/90) of frogs were infected with parasites, the total helminth intensity within infected frogs ranged from 1 to 367, and the mean intensity was 28.49. The infection rates and intensities were 78.89% and 22.89 for trematodes, 50.00% and 5...

Nematodes, belonging to the family Thelastomatidae, are parasites of saprophytic terrestrial arthropods, mainly cockroaches. American cockroach Periplaneta americana (Linnaeus, 1758) has high environmental adaptability, and has been spread worldwide by human activity. There are several reports of thelastomatid parasitic nematodes of P americana in the world. Here, the thelastomatid nematode Hammerschmidtiella diesingi (Hammerschmidt, 1838) (Oxyuridomorpha: Thelastomatidae), isolated from P americana is recorded for the first time in Japan...
