First record of Troglotrema acutum (Trematoda: Troglotrematidae) from a pine marten Martes martes in Germany
We examined 438 fresh skulls of pine marten (Martes martes) from Germany to check for the presence of the cranial trematodeTroglotrema acutum. The parasite was detected in the frontal sinuses of one 3-year-old road-killed male from the Rhoen Mountains (Thuringia). We detected 19 adultT. acutum and 34 eggs. The infested pine martens showed no deformations or lesions of the skull. This is the first time that specimens of the trematode were recovered from a pine marten from Germany, but the low prevalence of 0.23% confirms that the pine marten is only a rare host ofT. acutum.

Detecting Fasciola hepatica and Fasciola gigantica microRNAs with loop-mediated isothermal amplification (LAMP)
AbstractFascioliasis is a parasitic infection typically caused by two common parasites of class Trematodo, genusFasciola, namelyFasciola hepatica andFasciola gigantica. The widespread of these species in water and food makes fascioliasis become a global zoonotic disease that affects 2.4 million people in more than 75 countries worldwide. Typically,F. hepatica andF. gigantica can be recognized by parasitological techniques to detectFasciola spp. eggs, immunological techniques to detect worm-specific antibodies, or by molecular techniques such as PCR to detect parasitic genomic DNA. Recently, miRNAs have been raised as a key...

Immunomodulatory and antiparasitic effects of garlic –arteether combination via nitric oxide pathway in Plasmodium berghei -infected mice
AbstractMany reports indicate medicinal value of garlic (Allium sativum), a popular herbal medicine used worldwide, and its therapeutic effect against several diseases. Earlier studies in our laboratory have shown a potential therapeutic role of garlic –artemisinin combination in mice infected withPlasmodium berghei. A single dose of α, β-arteether with three oral doses of garlic provides almost 95% protection. The present study aims to understand the mode of action of this combination. We have documented the level of nitric oxide (NO), a key molecule of protection and have seen in the reversal of organ mo...

Drug-containing hydrophobic dressings as a topical experimental therapy for cutaneous leishmaniasis
AbstractCutaneous leishmaniasis (CL), a clinical condition caused mainly byLeishmania amazonensis in Brazil, is characterized by topical, painless ulcers. The current treatment, based on intravenous administration of pentavalent antimonials, presents low adherence by patients and may cause serious adverse effects, leading to the need for searching new therapeutic options. Thus, this study aimed at evaluating a topical administration of “intelligent dressings” as an alternative treatment for CL. BALB/c mice were infected withL. amazonensis promastigotes.

Automatic detection of Plasmodium parasites from microscopic blood images
AbstractMalaria is caused byPlasmodium parasite. It is transmitted by femaleAnopheles bite. Thick and thin blood smears of the patient are manually examined by an expert pathologist with the help of a microscope to diagnose the disease. Such expert pathologists may not be available in many parts of the world due to poor health facilities. Moreover, manual inspection requires full concentration of the pathologist and it is a tedious and time consuming way to detect the malaria. Therefore, development of automated systems is momentous for a quick and reliable detection of malaria. It can reduce the false negative rate and ...

Prevalence and determinants of gastrointestinal parasite infection in intensively managed pigs in Nsukka agricultural zone, Southeast, Nigeria
AbstractGastrointestinal parasite (GIP) infection in pigs constrains swine production and enhances dissemination of zoonotic parasites, especially in the tropics. Therefore, an epidemiological study to determine prevalence and risk factors of GIP infection in intensively managed pigs in Nsukka, was conducted. Faecal samples from 1400 pigs, randomly collected from 40 farms, were examined for GIP eggs following standard protocol. Data on involvement of pig farmers in risk practices that enhance endoparasitic infection in piggeries were obtained using structured questionnaire.

Molecular characterization of β-tubulin gene associated with benzimidazole resistance in larvae of field isolates of Parascaris (Nematoda: Ascarididae)
AbstractSince the past 2  decades, an increasing number of resistance to the Benzimidazoles (BZs) have been reported in nematode parasites of livestock. More recently, detection of single-nucleotide polymorphisms (SNPs) at codons of 167, 198 or 200 of the β-tubulin gene has been attributed to the occurrence of resistance. In the present study, we investigated the presence of those SNPs in the β-tubulin isotype-1 gene in different isolates ofParascaris in horse. Also, the mitochondrial (mt) and ribosomal genes were sequenced for species confirmation of the isolates. The analysis of sequences inferred from COI...

Daughter cyst sign in liver hydatid cyst
AbstractDaughter cyst sign is one of the most characteristic imaging findings of liver hydatid cysts. It is schematically divided into two types according to the daughter cyst localization in regard to the hydatid cyst wall: endogenous daughter cysts and exogenous daughter cysts. The endogenous daughter cyst is presented by a small cyst that protrudes into the lumen of the cystic mass. The exogenous daughter cysts are enclosed in the laminated layer then gradually pushed outwards giving the hydatid a bumpy appearance that distorts the classic circular radiological image. Imaging findings could detect these daughter cysts a...

Evaluation of Toxoplasma gondii propagated in specific pathogen free embryonated chicken egg, for diagnosis of toxoplasmosis in equids and human
AbstractToxoplasma gondii (T. gondii) is a worldwide distribution infects a wide variety of mammals, including humans. The present study aimed to detect the efficacy of soluble and wholeT. gondii antigens propagated in specific pathogen-free of embryonated chicken egg (SPF-ECE) used to improve the potency of serological assays for diagnosis of toxoplasmosis in equids and human. Total of 220 serum samples from 170 equids (90 donkeys and 55 horses and 25 mules) and 50 humans were collected from different governorates in Egypt during the period from October 2017 to March 2018. CrudeT. gondii tachyzoites antigens from low or h...

Prevalence of Giardia intestinalis with other co-infecting parasites in Barak Valley, Assam, India: a molecular approach
AbstractGiardia intestinalis was included in the World Health Organization ’s Neglected Disease Initiative in 2004 as it may range from asymptomatic to chronic or severe diarrhoea and chronic disorders post-infection. The present study aimed to find out the rate of sole infection ofG. intestinalis and co-infection of this with other protozoan parasites among the inhabitants of Barak Valley region of Southern Assam by conventional and molecular detection. A total of 1168 samples were collected from different groups of individuals, all the collected samples were subjected to microscopy after specific staining by Lugol ...

Parasitic pneumonia caused by Paragonimus spp. in a wild Royal Bengal Tiger, Mysuru, South India
In this report, we have described the gross and histopathological findings ofParagonimus fluke infection in lungs of tiger. The postmortem examination of sub adult male wild tiger (Panthera tigris tigris) died in captivity was conducted, earlier which was rescued by Forest Department, Mysuru, Karnataka, India. External examination of carcass revealed pale oral and conjunctival mucous membranes with sunken eye balls. During necropsy, moderate congestion, consolidation and numerous transparent to dark encysted lesions were found in the parenchyma of all lobes of lungs visible grossly on pleural surface. Lungs were hemorrhagi...

Upregulation of gametocytogenesis in anti-malarial drug-resistant Plasmodium falciparum
In this study, artemisinin-resistantP. falciparum parasites were tested for the development of AID forms and their recovery. Interestingly, it was found that exposure of an asynchronous culture of artemisinin-resistantP. falciparum IPC 5202 to DHA, a line carrying a mutation in thePfK13 gene that is linked to artemisinin resistance, also results in dormancy. Both the ring and some late stages of these AID forms recovered after 10 –15 days. Furthermore, a high proportion of the recovered dormant forms developed into sexual forms or gametocytes after 3–4 weeks, which is almost a 7–8 times higher r...
