BACKGROUND Detection of lipoarabinomannan (LAM), a Mycobacterium tuberculosis (Mtb) cell wall antigen, is a potentially attractive diagnostic. However, the LAM-ELISA assay has demonstrated variable sensitivity in diagnosing TB in diverse clinical populations. We therefore explored pathogen and host factors potentially impacting LAM detection. METHODS LAM-ELISA assay testing, sputum smear and ...

PURPOSE Oculocutaneous albinism (OCA) is a group of autosomal recessive disorders characterized by deficient synthesis of melanin pigment and associated with common developmental abnormalities of the eye. It is one of the major causes of childhood blindness in India. The disease is common among an ethnic group (Tili) of Eastern India, which represents about 12.56% of the Bankura district popula...

A gp63PCR method was evaluated for the detection and characterization of Leishmania (Leishmania) (L.) parasites in canine lymph node aspirates. This tool was tested and compared to other PCRs based on the amplification of 18S ribosomal genes, a L. infantum specific repetitive sequence and kinetoplastic DNA minicircles, and to classical parasitological (smear examination and/or culture) or serol...

For many years, the principles of genetics have been applied to crop variety improvement with great success. Severa1 crop species, notably corn, wheat, and tomato, have been used as model genetic systems because of their central importance to food production. Until recently, virtually a11 progress in both breeding and model genetic systems has relied on a phenotypic assay of genotype. Because t...

Campylobacter is genetically highly diverse and undergoes frequent intraspecific recombination. Turkeys have been identified as an important reservoir for Campylobacter jejuni which is of public health significance. The assessment of the genetic diversity among Campylobacter population is critical for our understanding of the epidemiology of this bacterium. The genetic profiles were different a...

objective(s): fascioliasis is a zoonotic parasitic disease caused by liver fluke species of fasciola hepatica and fasciola gigantica. differentiation of these two species, based on their morphological characteristics, is difficult. the current study aimed to use pcr-rflp assay to distinguish between f. hepatica and f. gigantica , based on profiles of rflp, produced by effect of endonucleases on...

The present study aimed at comparing the trypanosome specific 18S-PCR-RFLP using samples stored either on Whatman filter papers (PCR-RFLP-fp) or in a commercial cell lysis and DNA protecting buffer (PCR-RFLP-pb) with the haematocrit centrifugation technique (HCT), a method widely used for the diagnosis of African Animal Trypanosomosis. Out of 411 head of cattle, 49 (11.92%) (CI=8.95-15.45) scor...

Fusarium Head Blight is an important wheat disease in the Argentine Pampas region, being Fusarium graminearum the predominant pathogen. DNA polymorphism of the isolates was analyzed by IGS-RFLP and ISSR. IGS-RFLP and ISSR profiling were carried out using six endonucleases and eight primers, respectively. IGS-RFLP yielded 41 bands, 30 of which were polymorphic while ISSR produced 87 bands with 4...

background: dermatophytes are the most common causative agents of superficial mycoses. species identification of these fungi is important from therapeutic and epidemiological point of wive. traditional approaches for identification of dermatophytes at the species level, relying on macroscopic and microscopic features of the colonies, usually are time-consuming and unreliable in many circumstanc...

The Xiphinema americanum group of species is responsible for vectoring several important virus diseases to perennial crops. Variability of transmission of viruses by different species, and difficulties in separating species by morphometric measurements alone, make it essential to reassess the taxonomic position of several species in the group. The measurement of DNA sequence variability is a se...
