light and electron microscopic studies on the pars intermedia of the chameleon.	the neurointermediate lobe of the hypophysis in the chameleon (chamaeleo dilepis) was examined with light and electron microscopic methods, with special reference to the cytology of the pars intermedia (pi). the pi is the largest lobe of the hypophysis consisting of (1) dark cells with secretory granules ranging from 200-600 nm; (2) light cells, far fewer in number, containing granules 150-300 nm in diameter; (3) stellate, non-secretory cells. the secretory cells abut onto the perivascular basal ...	1976	1268936
chlamydial and poxvirus infections of circulating monocytes of a flap-necked chameleon (chamaeleo dilepis).	of blood films examined from 170 specimens of 15 chamaeleo spp. in tanzania, three c. dilepis had an intracytoplasmic inclusion within monocytes. one of the lizards was maintained in captivity and was sequentially bled over a 55 day period. at 46 days, a second type of inclusion was occasionally seen within monocytes. the lizard became ill and was euthanatized on day 55. all circulating monocytes were found to have either one or both types of inclusions. histologic examination of multiple tissue ...	1990	2174468
ticks (acarina: ixodidae) of reptiles from central, lusaka and southern provinces of zambia.	during the period 1988-1991, reptiles (23 snakes, 36 tortoises, 25 chameleons and 2 monitor lizards) from central, lusaka and southern provinces of zambia were caught and checked for ticks. only 2 snakes, respectively one python sebae (gmelin, 1789) and one bitis arietans (merrem, 1820), 8 tortoises, respectively seven geochelone pardalis (bell, 1828) and one kinixys belliana (gray, 1831) were found infested with a small number of ticks: nymphs and adults of aponomma latum (koch, 1844) and ambly ...	1993	8065818
lizard erythrocytic virus in east african chameleons.	giemsa-stained peripheral blood films from 9 of 50 flap-necked chameleons, chamaeleo dilepis, and 1 of 18 fischer's chameleons, bradypodion fischeri, collected in tanzania had intraerythrocytic inclusions. in c. dilepis, acidophilic inclusions were associated with the albuminoid vacuoles reported in typical pirhemocytonosis of saurians. under transmission electron microscopy, the acidophilic inclusions were aggregations of partially or completely formed viral particles consistent with those of t ...	1993	8445790
six new species of coccidia (apicomplexa: eimeriidae) from east african chameleons (sauria: chamaeleonidae).	coprological examination of 83 east african chameleon specimens revealed 32.5% prevalence of coccidian parasites. six species are described as new: eimeria tilburyi n. sp. from chamaeleo jacksonii has cylindrical oocysts, 28.9 (26-33) x 16.0 (14-18) microm and occasionally a small polar granule. sporocysts are oval to ellipsoidal, 10.6 (9-12) x 7.2 (6-8) microm, without stieda and substieda bodies; endogenous stages were found in the gall bladder. oocysts of eimeria largeni n. sp. from chamaeleo ...	2000	10780560
a check-list of the nematode parasites of south african serpentes (snakes) and sauria (lizards).	published records, in combination with own data have been brought together to provide data on parasite/host relationships of reptiles that occur in the republic of south africa. a total of 62 nematode species belonging to 23 genera and 11 families are recorded from 20 snake and 21 lizard species. the genera kalicephalus, spauligodon, ophidascaris and abbreviata are especially well represented with between five and eight species per genus. the most nematode species were recorded from the flap-nec ...	2000	10843317
a description of two new species of coccidia (apicomplexa: eimeriidae) from african reptiles with nomenclatural corrections for two caryospora and one eimeria species from snakes.	two new species of coccidian parasites are described from african reptiles. oocysts of eimeria foulshami sp. n. from the plated lizard gerrhosaurus major bottegoi del prato of sudan are ellipsoidal, 24.1 x 14.9 (23-26.5 x 14-17.8) microm with a bilayered, colourless oocyst wall and lack polar granules. the ellipsoidal sporocysts average 8.6 x 4.6 (7-10.6 x 4.4-7) microm and possess a prominent, globular, sporocyst residuum. oocysts of caryospora regentensis sp. n. from the eastern green mamba de ...	2001	11266129
two new species of isospora schneider, 1881 (apicomplexa: eimeriidae) from the flap-necked chameleon chamaeleo dilepis (sauria: chamaeleonidae) in the republic of namibia.	two new species of isospora schneider, 1881 from flap-necked chameleons chamaeleo dilepis leach are described from the faeces of specimens collected in the republic of namibia. oöcysts of isospora freedi n. sp. from one of four (25%) c. dilepis collected in the east caprivi district are spherical to subspherical, with a smooth, colourless, bilayered wall, measure 23.7 × 21.2 μm and have a length/width (l/w) ratio of 1.1. the micropyle and the oöcyst residuum are absent but a polar granule is som ...	2012	22890376
infection with a novel derogenid trematode in a flap-necked chameleon (chamaeleo dilepis).	a 2-year-old female flap-necked chameleon (chamaeleo dilepis) was presented with a history of anorexia. on physical examination, three 11×4×2 mm, light tan-pink, raised, gelatinous, freely movable, poorly demarcated, raised nodules were identified within the oral cavity. an impression smear contained multiple, light blue to green structures exhibiting an 18×35 μm, elliptical-shaped anterior portion and a single 1×150 μm filament with a tapered end. initial differential etiologies included tremat ...	2017	28817168
