Background: Lipophosphoglycan 3 (LPG3) is required for the LPG assembly, a well known virulent molecule. In this study, the LPG3 gene of the lizard and mammalian Leishmania species were cloned and sequenced. A three-dimensional structure (3D) for the target sequence was also predicted by comparative (homology) modeling. Materials and Methods: An optimization PCR amplification was performed o...
In this study, we hypothesized that the life history traits of Leiothrix spiralis and L. vivipara would be linked to soil factors of the rupestrian grasslands and that rosette size would be influenced by soil moisture. Soil analyses were performed from five populations of L. spiralis and four populations of L. vivipara. In each area, three replicates were employed in 19 areas of occurrence of L...

Retinal ganglion cell (RGC) axons in lizards (reptiles) were found to regenerate after optic nerve injury. To determine whether regeneration occurs because the visual pathway has growth-supporting glia cells or whether RGC axons regrow despite the presence of neurite growth-inhibitory components, the substrate properties of lizard optic nerve myelin and of oligodendrocytes were analyzed in vitr...
parasites of lizards has recently become the subject of sectional interests. In the absence of any objective criteria for classifying the group, two nomenclatures have come into current usage. Workers with interests in the natural history of the lizard parasites have emphasized the features that distinguish lizard and mammalian parasites and have tended to give the lizard parasites generic rank...
Habitat fragmentation is well known to adversely affect species living in the remaining, relatively isolated, habitat patches, especially for those having small range size and low density. This negative effect has been critical in coastal resting habitats. We analysed the lizard composition and richness of restinga habitats in 16 restinga habitats encompassing three Brazilian states (Rio de Jan...
Glossal stomatitis was observed in a Sudan plated lizard (Gerrhosaurus major) with severe dyspnea. On necropsy, intranuclear inclusion bodies were seen in the periglottal lingual epithelium. Labial stomatitis was seen in a second Sudan plated lizard and a black-lined plated lizard (G. nigrolineatus). Degenerate polymerase chain reaction (PCR) primers targeting a conserved region of herpesvirus ...
Background: Currently, there are no effective vaccines against leishmaniasis, and treatment using pentavalent antimonial drugs is occasionally effective and often toxic for patients. The PTR1 enzyme, which causes antifolate drug resistance in Leishmania parasites encoded by gene pteridine reductase 1 (ptr1). Since Leishmania lacks pteridine and folate metabolism, it cannot synthesize the pterid...
background : amelogenins are the major components of enamel matrix proteins. enamel matrix derivatives (emd) can be used in periodontal diseases to regenerate periodontal tissues. the main aim of this study was to evaluate ex-pression of full-length functional recombinant human amelogenin (rham) in iranian lizard leishmania (i.l.l.) as an alternative eukaryotic expression system. methods : huma...
