Pregnancy is a special physical period in reproductive age women, which has a beneficial influence on the course of certain autoimmune diseases. It has been recently suggested that the microbiome undergoes profound changes during pregnancy that are associated with host physiological and immunological adaptations. The maternal microbiome remodeling during pregnancy is an active response of the mother, possibly to alter immune system status and to facilitate metabolic and immunological adaptations, which are needed for a successful pregnancy...

Spirocerca lupi is the esophageal nematode of dogs. Early, transient eosinophilia occurs in experimentally infected dogs, but is absent in advanced cases, suggesting that the nematode evades the dog's immune system. Lectins are proteins or glycoproteins of plant or animal origin, binding different saccharides, with varying specificities and avidities, used to characterize surface haptens in plant and animal parasitic helminths. This study investigated the in vitro binding of six lectins (Concanavalin A [ConA], wheat germ agglutinin [WGA], peanut agglutinin [PNA], soybean agglutinin [SBA], Dolichus biflorus agglutinin [DBA] and Ulex earopaeus agglutinin I [UEA]) to the surface of S...

Helminth infections are the cause of morbidity in Cambodian cattle but other factors such as nutritional deficiencies and concurrent diseases may enhance the effects of parasites. The present study aimed to investigate the impact of anthelmintic treatment, feed supplementation, or both on gastrointestinal strongyle (GIS) and trematode infections as well as on morbidity parameters in Cambodian village cattle. At the beginning of the dry season, cattle populations in six villages were randomly assigned to a group: (A) receiving anthelmintic treatment (ivermectin+clorsulon) at week 0; (P) feed pellet supplementation during week 0-13 or both (AP)...

Organisms throughout biology need to maintain the integrity of their genome. From bacteria to vertebrates, life has established sophisticated mechanisms to detect and eliminate foreign genetic material or to restrict its function and replication. Tremendous progress has been made in the understanding of these mechanisms which keep foreign or unwanted nucleic acids from viruses or phages in check. Mechanisms reach from restriction-modification systems and CRISPR/Cas in bacteria and archaea to RNA interference and immune sensing of nucleic acids, altogether integral parts of a system which is now appreciated as nucleic acid immunity...

Nine helminth parasites were used as biological tags to discriminate diverse areas of Scomber colias Gmelin, 1789. During three seasons, a total of 369 fish were examined in four zones off the Tunisian coast, including Bizerte in the north, Kelibia and Mahdia in the centre and Zarzis in the south. Discriminant analyses were used to identify distinct areas of S. colias. Fish from Bizerte were grouped as one area and were correlated negatively with the monogenean Grubea cochlear and the digenean Lecithocladium excisum...

Alternative strategies to synthetic chemical drugs are needed in livestock and are a key issue in organic farming today. This study aimed at examining the potentialities of sainfoin, a legume rich in condensed tannins, as a nutraceutical that combines nutritive and antiparasitic effects in rabbits. To test the effect of infection with a helminth (I: infected groups; NI: not infected groups) and the effect of substituting 40% of the alfalfa in a control diet (C) with sainfoin (diet S), four groups of 16 weaned rabbits were arranged according to a 2×2 bifactorial design...

It is estimated that over a billion people are infected with soil-transmitted helminths (STHs) globally with majority occurring in tropical and subtropical regions of the world. The roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura), and hookworms (Anclostoma duodenale and Necator americanus) are the main species infecting people. These infections are mostly gained through exposure to faecally contaminated water, soil or contaminated food and with an increase in the risk of infections due to wastewater and sludge reuse in agriculture...

M esostephanus appendiculatus (Family: Cyathocotylidae) is one of the unique trematodes that complete their cycles in human and animal intestines in many countries of the world. The main source of its transmission is eating raw or undercooked infected fish muscle. Earliest analyses of genes to different parasites supported the analysis of helminthes either biological or morphological. This paper detected M. appendiculatus sequence with GenBank accession number gb (KY026782). Comparison of M. appendiculatus with other helminthes using BioEdit 7 and MEGA7 program shows some similarity in different points along its sequence...

Cystic and alveolar echinococcosis are severe chronic helminthic diseases caused by the cystic growth or the intrahepatic tumour-like growth of the metacestode of Echinococcus granulosus or Echinococcus multilocularis, respectively. Both parasites have evolved sophisticated strategies to escape host immune responses, mainly by manipulating and directing this immune response towards anergy and/or tolerance. Recent research studies have revealed a number of respective immunoregulatory mechanisms related to macrophages and dendritic cell as well as T cell activities (regulatory T cells, Tregs)...

BACKGROUND: Globally, in 2010, approximately 1.5 billion people were infected with at least one species of soil-transmitted helminth (STH), Ascaris lumbricoides, Trichuris trichiura, hookworm (Ancylostoma duodenale and Necator americanus). Infection occurs through ingestion or contact (hookworm) with eggs or larvae in the environment from fecal contamination. To control these infections, the World Health Organization recommends periodic mass treatment of at-risk populations with deworming drugs...

BACKGROUND: A method is outlined for the use of an individual-based stochastic model of parasite transmission dynamics to assess different designs for a cluster randomized trial in which mass drug administration (MDA) is employed in attempts to eliminate the transmission of soil-transmitted helminths (STH) in defined geographic locations. The hypothesis to be tested is: Can MDA alone interrupt the transmission of STH species in defined settings? Clustering is at a village level and the choice of clusters of villages is stratified by transmission intensity (low, medium and high) and parasite species mix (either Ascaris, Trichuris or hookworm dominant)...

BACKGROUND: Understanding the prevalence of soil-transmitted helminth infections is necessary to plan control strategies and focus on highly endemic regions for preventive chemotherapy and improved sanitation facilities. India is known to be endemic for soil-transmitted helminth infections. METHODS: To understand the prevalence, spatial distribution and identify high-risk zones, a systematic search of published literature was carried out based on PRISMA guidelines from the year 2000 to 2015...

Cellular hypo responsiveness observed during helminth infections are attributed to factors like Antigen presenting cells (APC) dysfunction, increased Interleukin-10(IL-10), regulatory T cells and induction of CD4(+) T (Th) cell apoptosis.. Increased Fas ligand (FasL) expression on the surface of B-1 cells and induction of apoptosis of Th cells by FasL expressing B-1 cells due to helminth infection was demonstrated in murine model of helminth infection where as profile of FasL expression, Th cell apoptosis and correlation between these two populations of cells in clinical filariasis remain unknown...

BACKGROUND: Since 2001, Haiti's National Program for the Elimination of Lymphatic Filariasis (NPELF) has worked to reduce the transmission of LF through annual mass drug administration with diethylcarbamazine and albendazole. The NPELF reached full national coverage with MDA for LF in 2012, and by 2014, a total of 14 evaluation units (48 communes) had met WHO eligibility criteria to conduct LF transmission assessment surveys (TAS) to determine whether prevalence had been reduced to below a threshold, such that transmission is assumed to be no longer sustainable...
