poikilotherms as reservoirs of q-fever (coxiella burnetii) in uttar pradesh. | water snakes (natrix natrix), rat snakes (ptyas korros), cobras (naja naja), pythons (python molurus), tortoises (kachuga sp.), plankton fish (cirrhina mrigala), frogs (rana tigrina), toads (bufo sp.) and monitors (varanus indicus) were screened for evidence of q-fever infection by the capillary agglutination test on sera to detect antibodies and/or by attempts to demonstrate coxiella burnetii in spleen and liver samples. sero-reactors were observed among water and rat snakes, pythons and tortoi ... | 1979 | 459042 |
observations on the monitor lizard, varanus indicus (daudin), as a rat-control agent on ifaluk, western caroline islands. | | 1966 | 5298046 |
identification of a truncated tn1721-like transposon located on a small plasmid of escherichia coli isolated from varanus indicus. | the 9.1 kb plasmid pdewt1 was isolated from an escherichia coli strain obtained from the faeces of a free-living lizard (varanus indicus) in indonesia. this plasmid mediated tetracycline resistance via a tet gene of hybridization class a. molecular analysis of a 7755 bp segment of plasmid pdewt1 including the tetr-tet(a) region and its flanking areas suggested that pdewt1 harboured a truncated copy of the tet(a)-carrying transposon tn1721 in which the part responsible for chemotaxis and transpos ... | 2003 | 12675900 |
morphological characteristics of blood cells in monitor lizards: is erythrocyte size linked to actual body size? | blood cell morphology and count are not uniform across species. recently, between-species comparisons revealed that the size of red blood cells is associated with body size in some lizard taxa, and this finding was interpreted in the context of the metabolic theory. in the present study, we examined the numbers and the size of blood cells in 2 species of monitor lizards, the mangrove-dwelling monitor (varanus indicus) and the savannah monitor (v. exanthematicus), and we compared these traits in ... | 2012 | 23621470 |
hastospiculum spiralis n. sp. (nematoda: diplotriaenoidea: dicheilonematinae), from an indonesian mangrove monitor, varanus indicus (reptilia: sauria: varanidae). | while examining an imported indonesian mangrove monitor, varanus indicus (reptilia: sauria: varanidae), for helminths, a new species of hastospiculum was collected and is described as hastospiculum spiralis n. sp. this species differs from all other members of the genus in caudal papillae number and arrangement, a pair of large cephalic papillae, and a spirally twisted left spicule in males. additionally, h. spiralis n. sp. differs from certain hastospiculum species by the right and left spicule ... | 1998 | 9576513 |
a new blue-tailed monitor lizard (reptilia, squamata, varanus) of the varanus indicus group from mussau island, papua new guinea. | we describe a new species of varanus from mussau island, north-east of new guinea. the new species is a member of the varanus indicus species group and is distinguished from all other members by both morphological and molecular genetic characters. it is the third species of varanus reported from the bismarck archipelago and the first record of a yellow tongued member of the varanus indicus species group from a remote oceanic island. the herpetofauna of mussau island has not been well studied but ... | 2016 | 27103877 |
ontogeny of sexual size dimorphism in monitor lizards: males grow for a longer period, but not at a faster rate. | monitor lizards belong to the largest and the most sexually dimorphic lizards in terms of size, making this group an ideal model for studies analyzing ontogenetic causes of sexual dimorphism. understanding of these ontogenetic factors is essential to the current discussion concerning patterns of sexual dimorphism in animals. we examined the ontogenetic trajectories of body weight and snout-vent length to analyze the emergence of sexual size dimorphism. experimental animals were 22 males and 13 f ... | 2010 | 21110717 |
physiological ecology of the mangrove-dwelling varanid varanus indicus. | some species of terrestrial lizards in wet-dry tropical climates reduce their body temperatures (t(b)'s) and activity and lower their metabolic rates during the dry season when food and water resources are scarce. however, semiaquatic lizards have access to water and presumably food throughout the year, so it is possible that they will not have the seasonal response seen in terrestrial species. we studied the thermal biology, energetics, and water flux of varanus indicus, a semiaquatic, mangrove ... | 2008 | 18759555 |
hnk-1 in morphological study of development of the cardiac conduction system in selected groups of sauropsida. | human natural killer (hnk)-1 antibody is an established marker of developing cardiac conduction system (ccs) in birds and mammals. in our search for the evolutionary origin of the ccs, we tested this antibody in a variety of sauropsid species (crocodylus niloticus, varanus indicus, pogona vitticeps, pantherophis guttatus, eublepharis macularius, gallus gallus, and coturnix japonica). hearts of different species were collected at various stages of embryonic development and studied to map immunore ... | 2019 | 30306736 |
taxonomy of micronesian monitors (reptilia: squamata: varanus): endemic status of new species argues for caution in pursuing eradication plans. | in the light of recent phylogenetic studies, we re-assess the taxonomy and biogeography of the varanus populations distributed in the micronesian islands of palau, the western carolines and the marianas. whether these populations are of natural origin or human introductions has long been contentious, but no study has fully resolved that question. here, we present molecular and morphological evidence that monitor lizards of the varanus indicus group reached both palau and the mariana islands some ... | 2020 | 32537217 |
