Background and Purpose: Fungal keratitis is a suppurative, ulcerative, and sight-threatening infection of the cornea that sometimes leads to blindness. The aims of this study were: recuperating facilities for laboratory diagnosis, determining the causative microorganisms, and comparing conventional laboratory diagnostic tools and semi-nested PCR. Materials and Methods: Sampling was conducted in...

Theileria annulata, as a pathogenic agent of tropical theileriosis, gives rise annually to serious economic losses in cattle industry of Iran. The carrier cattle, harbouring the latent forms of Theileria annulata, play a major role in infecting tick vectors and in disseminating the infection. The aim of this study was determining the carrier cattle, infected with Theileria annulata in Golestan ...
Identification of Cutaneous Leishmaniasis-causing Species Using Semi-Nested PCR in Kohgiluyeh and Boyer-Ahmad Province During 2013-2019
We have modified an existing semi-nested multiplex polymerase chain reaction (PCR) by adding one Plasmodium knowlesi-specific nested PCR, and validated the latter against laboratory and clinical samples. This new method has the advantage of being relatively affordable in low resource settings while identifying the five human Plasmodium species with a three-step PCR.
Dengue virus (DENV) causes various clinical symptoms of differing severity based on time of infections. The existing laboratory methods, semi-nested PCR and Dengue IgM ELISA, still have limitations for diagnosis. A commercially available rapid immunochromatographic dengue NS1 antigen and IgM antibody tests in comparison with semi-nested PCR and IgM ELISA for confirmation of DENV infection were ...
BACKGROUND PCR detection of human cytomegalovirus (HCMV) DNA in amniotic fluid (AF) is the most sensitive tool for diagnosis of fetal infection, but has sub-optimal sensitivity. It has been suggested that inhibition by AF reduces the sensitivity of this assay, however this assumption has never been thoroughly studied. Several PCR assays have been shown to improve sensitivity, but comparative st...
BACKGROUND Toxoplasma gondii is a zoonotic pathogen that can infect a range of animals and humans. Ingestion of T. gondii oocysts in soil is a significant transmission route for humans and animals acquiring toxoplasmosis. In the present study, we developed a new semi-nested PCR method to determine T. gondii oocysts distribution in soils in northwestern China. RESULTS The one tube semi-nested ...
