Review ArticleOpen accessIn the abstractReview on Apiary Management and Antimicrobial Compounds as Alternative Prevention or Treatment for Honeybee DiseasesChanpen Chanchao, Marko Stoić, Mikio Yoshiyama, Kiyoshi KimuraHoneybees are important in terms of pollinators and bee products. However, honeybee colonies keep declining due to colony collapse disorder, loss of food sources, environmental deterioration, pesticide exposure and various diseases, as well as the interaction of these causes. Pathogenic infections are high because there is an antagonistic coevolution between host and pathogen/parasite, which leads to a reciprocal adaptation, as … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 15 Jan 2018 · 7,743 accessesView PDFCite
Review ArticleOpen accessIn the abstractLivestock Hydatid Disease (Cystic Hydatidosis) in Libya: A ReviewMohamed M. Ibrahem, Wafa M. Ibrahem, Mostafa M. Abdorrahem, Kawther M. IbrahemCystic hydatid disease is an infection caused by the larval stage of a cestode parasite called Echinococcus granulosus. Hydatid cysts are one of the major parasitic infections in Libya that causes many health problems to human and responsible for economic losses because of the condemnation of the slaughtered animals infected viscera as well as reducing the quality and quantity of … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 2 · 31 May 2016 · 8,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractIN VIVO ANTIPLASMODIAL ACTIVITY AND ACUTE TOXICITY OF STANDARDIZED EXTRACT OF EURYCOMA LONGIFOLIA JACK. ROOT TRADITIONALLY USED TO TREAT MALARIAEti Nurwening Sholikhah, Mahardika Agus Wijayanti, MustofaA series of studies has been conducted to prove the Eurycoma longifolia Jack. root as an antimalarial. However, the in vivo antiplasmodial activity of E. longifolia Jack. root standardized extract and its lethal dose 50% (LD50) values is unknown. In vivo antiplasmodial activity was conducted on Plasmodium berghei infected Swiss mice as malaria model with 4-day suppression methods. Sixty mice … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 27 Dec 2013 · 7,736 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntigenic and Immunogenic Components of Haemonchus longistipes Identified by Western ImmunoblotingE. M. El Hassan, Sabry M. El-BahrThe present study aimed to examine the ways that the Haemonchus longistipes components interact with the host by investigating the components of the parasite which acted as antigens during infection and those who are capable of inducing immune response when administered as immunogens. Adult H. longistipes worms (300 females and 200 males) were obtained from the abomasums of naturally infected … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 3 · 20 Sep 2012 · 7,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Biopterin Transporter (BT1) Gene on Growth and Infectivity of LeishmaniaManju Jain, Vandana S. Dole, Peter J. Myler et al.Leishmania are known to be auxotrophic for pteridines that are known to play a critical role in the parasites survival. In the present work the role of biopterin transporter in the growth of the parasite and infectivity in to macrophages has been worked out. The role of biopterin transporter in the susceptibility of Leishmania to antimonial compounds has also been … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 7,040 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and functional characterization of a novel lysine-rich protein from Entamoeba histolyticaAlka Mehra, Sudha Bhattacharya, Alok BhattacharyaIn an attempt to understand the role of genes with no known function, in the protozoan parasite Entamoeba histolytica, an analysis of the proteome was carried out and a Lysine-Rich protein (KRP) was identified for further study. This protein has a modular structure with four domains and was found to be expressed and localized to the cell surface of E. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 7,709 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Heat Shock Transcription Factor Family in Entamoeba histolyticaConsuelo G. García, Ma. De la Luz Macias Argüelles, D. Guillermo P Ishiwara et al.The HSTF is a master molecule involved in the transcriptional control of several genes during different types of stress. This transcription factor is a very conserved protein identified in different organisms from bacterial to human. Entamoeba histolytica is the protozoan responsible for the human amoebiasis. This parasite is exposed to different kind of stress as changes in the pH, temperature, … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractPeculiarities of the Structure of Male Reproductive System in Trematode Parastrigea Robusta (Trematoda: Strigeidae)Rimma Meyramovna Ualiyeva, Kanat Kombarovich Akhmetov, Indira Bulatovna Altayeva, Alexey Vasilyevich SurovIt is well known that class Trematoda includes solely parasitic forms of flatworms. Therefore, they have developed diverse morphological and functional adaptations to the parasitic way of life. One of them is enormous fecundity, which allows quick and widespread settlement and finding hosts. Therefore, studying the reproduction apparatus of helminthes is the central problem of Parasitology. Studying functional morphology of … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 10 Jun 2017 · 7,647 accessesView PDFCite
InvestigationOpen accessIn the abstractHigh Frequency of Enteroparasite Infection in Dogs (Canis familiaris) in Urban Regions of Espírito Santo, BrazilRoberta Bastos Costa, Betânia Barreiro Santos, Gisele Pereira Valdetaro et al.The objective of this study was to perform examinations of canine fecal samples collected in the urban region, focusing on enteroparasitological diseases, common zoonosis that have their risk of transmission increased due to the growing number of stray dogs in these areas. One hundred and twenty fecal samples of stray dogs were collected from various locations of the studied region … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 29 Jan 2016 · 7,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractNitric Oxide Donors with Therapeutic Strategic in Experimental Schistossomiasis MansoniWander Rogério Pavanelli, Jean Jerley Nogueira da Silva, Carolina Panis et al.Schistosomiasis, an immune disease, remains a major public health problem in endemic area. To determine the influence of Nitric Oxide (NO) on this disease, we tested two compounds (Trans-[Ru(bpy)2(NO)SO3](PF6)-PF6 and Na2[Fe(CN)5(NO)]-SNP, which releases NO when activated by biological reducing agents, in BALB/c mice infected subcutaneously by Schistosoma BH strains. The parasitic activity of NO-donors was evaluated in this model by … …American Journal of Immunology, Vol. 10, Issue 4 · 24 Feb 2015 · 7,852 accessesView PDFCite
