Redefining () species complex in Greece focusing on the mitogenome of .

species complex, referred to as (), is distributed globally with some species distributed in specific regions and others spread globally. In Greece, () in dogs, and and in livestock, have been repeatedly reported however only based on morphological identification. Recently, there has been a great effort to accurately identify the species belonging to the species complex, using modern molecular tools and describe their spatial distribution.

Melatonin Administration to Pregnant Ewes for Coccidiosis Control in Their Offspring.

In livestock research, there has been a growing interest in the impact of melatonin on both health and disease conditions. The hypothesis of the present study was that melatonin treatment prenatally could support the immune competence and growth of experimentally infected lambs. This is the first study that aimed to investigate the impact of melatonin administration throughout pregnancy on immunity and oocyst excretion of pre-partum ewes and their offspring after experimental infection with species.

Anguillicola (Anguillicoides) crassus: Morphometric characteristics and pathogenicity in eels (Anguilla anguilla) in Greece.

Anguillicola (Anguillicoides) crassus is a swimbladder nematode parasite of Anguilla anguilla (Linnaeus, 1758). The present study investigates the morphology and pathogenicity of A. crassus in European eel, as well as, the effects of different aquatic environments on the infection of A.

Gastro-intestinal parasitism and control practices in dairy cattle in North-west Cameroon (Central Africa).

Purpose: The main objective of this study was to assess the gastrointestinal parasitism in relation with the worm control practices (WCP) in dairy cattle in areas of major importance for dairy/milk production of Cameroon.

Methods: Fresh fecal samples were randomly collected from 402 cattle from August to October 2016 in North West Cameroon, and analyze using the McMaster technique. Data on WCP were collected using a questionnaire.

Internal Parasites of Pigs and Worm Control Practices in Bamboutos, Western Highlands of Cameroon.

Internal parasites are limiting factors to successful, sustainable livestock production. Knowledge on how they are dealt with is important to prevent resistance to anthelmintics. The aim of this study was to describe the internal parasitism of indoor pigs in Bamboutos Division in Cameroon, as well as the attendant worm control practices.

An analysis of seroprevalence and risk factors for parasitic infections of economic importance in small ruminants in Greece.

A cross-sectional serological survey was carried out to screen the small ruminants of Thessaly, Greece, for infection with Haemonchus contortus, lungworms (i.e. Cystocaulus ocreatus, Muellerius capillaris, Protostrongylus rufescens and Neostrongylus linearis) as a group, and for Cysticercus tenuicolis, Linguatula serrata and Oestrus ovis.

Global geographic distribution of Trichinella species and genotypes.

Maximum entropy ecological niche modeling was utilized to describe the global geographic distribution of Trichinella species and genotypes and to assess their invasive risk in new areas other than the ones currently known. Also, space-time scan statistic was utilized to identify global spatiotemporal clusters of infection. A database containing 3209 records for 12 species and genotypes identified at the International Trichinella Reference Center (ITRC) as well as climate, elevation, and land cover data extracted from various databases were used.

Seroprevalence and risk factors associated with zoonotic parasitic infections in small ruminants in the Greek temperate environment.

A cross-sectional serological study was carried out to screen the sheep and goat population of Thessaly, Greece for evidence of infection with Toxoplasma, Toxocara, Leishmania, and Echinococcus and to determine the risk factors related to herd characteristics, herd management practices, farmer status, and the bioclimatic variables associated with these zoonotic parasitic infections. A total of 540 sheep and goat serum samples were examined. The seroprevalence of infection in all examined animals was 24.

Geographic distribution modelling for ruminant liver flukes (Fasciola hepatica) in south-eastern Europe.

Maximum entropy ecological niche modelling was utilised to predict the geographic range for fluke genotypes and haplotypes in south-eastern Europe, using the Maxent program. The lowest (0.832) and the highest (0.

Survey of gastrointestinal parasitic infections of beef cattle in regions under Mediterranean weather in Greece.

Gastrointestinal (GI) parasitic infections of beef cattle were investigated in 15 farms from 3 different regions of Greece, characterized by temperate Mediterranean climate, during two years. A total of 262 faecal samples were collected. Helminth eggs were detected in 42 (16%) samples.

Geographic distribution modeling and spatial cluster analysis for equine piroplasms in Greece.

Maximum entropy ecological niche modeling and spatial scan statistic were utilized to predict the geographic range and to investigate clusters of infections for equine piroplasms in Greece, using the Maxent and SaTScan programs, respectively. The eastern half of the country represented the culminating area with high probabilities (p>0.75) of presence of equine piroplasms and encompassed most regions with high concentration of equid host populations.

Genetic diversity of equine piroplasms in Greece with a note on speciation within Theileria genotypes (T. equi and T. equi-like).

Equine piroplasms in Greece were studied using the reverse line blot hybridization (RLB) assay. Three genotypes consisting of two Theileria (T. equi and T.

Seroprevalence of equine piroplasms and host-related factors associated with infection in Greece.

Serum samples were collected from a total of 544 equids that included 524 horses, 13 mules, and 7 ponies from various regions of mainland Greece and were examined by competitive-inhibition ELISA (cELISA) to evaluate the level of exposure of Greek equids to Theileria (Babesia) equi and/or Babesia caballi, the causative agents of piroplasmosis. Association between seropositivity and host-related factors of species, gender, age, origin, activity and location were investigated. The overall seroprevalence was 11.
