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 · 7,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe immunological aspects of Acanthamoeba infectionsNaveed A. KhanAcanthamoeba is a protozoan pathogen that is responsible for two recognized diseases; i) a blinding keratitis, most commonly associated with contact lens wear, and ii) a rare but fatal granulomatous encephalitis that usually is limited to immunocompromised patients. The fact that Acanthamoeba infections are generally limited to avascular cornea or immunocompromised patients suggests that the normal immune responses may be … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractHematological Changes during Chronic Toxoplasma gondii Infection in Pregnant Women in Makkah, Saudi ArabiaKhalil MohamedToxoplasma gondii is an obligate parasite and intracellular protozoans infect all kinds of animals and humans. The aim of the present study was to determine whether there was any effect on complete blood count parameters in the blood of pregnant women. A case-control study was performed in pregnant women divided into two groups according to their age: group one (17-27 … …American Journal of Infectious Diseases, Vol. 16, Issue 2 · 9 Apr 2020 · 7,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review of the Mechanisms of Faecal Coliform Removal from Algal and Duckweed Waste Stabilization Pond SystemsE. D.O. Ansa, E. Awuah, A. Andoh et al.The use of eco-technologies for wastewater treatment such as algal and duckweed-based pond systems is becoming popular in developing countries owing to its affordability and efficiency of pathogen removal in warm climates. The pathogen removal mechanisms of these treatment systems however is still not clearly understood and existing knowledge is also scattered in journals and books of different disciplines. The … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 5 Apr 2015 · 8,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenomic Distance between Thymidylate Synthase and Dihydrofolate Reductase Genes Does Not Correlate With Phylogenetic Evolution in BacteriaVitor Hugo MoreauProblem statement: Dihydrofolate Reductase (DHFR) and Thymidylate Synthase (TS) exist as bifunctional enzymes coded into unique polypeptide chain in protozoans. Bifunctional DHFR-TS is associated with an increase in the enzymatic activity by channeling the substrate between the active sites. In some bacteria, DHFR and TS genes are neighbors in the genome, whereas in others, they are located millions of base … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,188 accessesView PDFCite
