| amietia angolensis and a. fuscigula (anura: pyxicephalidae) in southern africa: a cold case reheated. | a study combining dna sequences of the mitochondrial 16s rrna gene, advertisement calls and morphology of some southern african river frogs confirms amietia vandijki (visser & channing, 1997) as a good species. the form presently referred to as amietia angolensis in southern africa is shown to comprise two species: amietia angolensis (bocage, 1866) known from angola, and amietia quecketti (boulenger, 1895) known from south africa, zimbabwe and lesotho. junior synonyms of a. quecketti include ran ... | 2013 | 26000433 |
| hepatozoon species (adeleorina: hepatozoidae) of african bufonids, with morphological description and molecular diagnosis of hepatozoon ixoxo sp. nov. parasitising three amietophrynus species (anura: bufonidae). | haemogregarines comprise a large group of apicomplexan blood parasites. in 1996 all anuran haemogregarines still in the genus haemogregarina danilewsky, 1885 were reassigned to the genus hepatozoon miller, 1908. most (11/15, 73%) african anuran hepatozoon species have been recorded from the family bufonidae, however, all these are recorded from only two host species, amietophrynus mauritanicus (schlegel, 1841) and amietophrynus regularis (reuss, 1833) from northern and central africa. to the aut ... | 2014 | 25526644 |
| ultrastructural comparison of hepatozoon ixoxo and hepatozoon theileri (adeleorina: hepatozoidae), parasitising south african anurans. | to date, only two haemogregarine parasite species have been described from south african anurans: hepatozoon ixoxo, infecting toads of the genus sclerophrys (syn. amietophrynus); and hepatozoon theileri, parasitising the common river frog, amietia quecketti. both species have been characterised using limited morphology, and molecular data from pcr amplified fragments of the 18s rrna gene. however, no ultrastructural work has been performed thus far. the aim of this study was to add descriptive i ... | 2017 | 27480595 |
| monophyly of the species of hepatozoon (adeleorina: hepatozoidae) parasitizing (african) anurans, with the description of three new species from hyperoliid frogs in south africa. | haemogregarines (apicomplexa: adeleiorina) are a diverse group of haemoparasites reported from almost all vertebrate classes. the most commonly recorded haemogregarines to parasitize anurans are species of hepatozoon miller, 1908. to date 16 hepatozoon species have been described from anurans in africa, with only a single species, hepatozoon hyperolli (hoare, 1932), infecting a member of the hyperoliidae. furthermore, only two hepatozoon species are known from south african anurans, namely hepat ... | 2017 | 29198245 |
| redescription and molecular diagnosis of hepatozoon theileri (laveran, 1905) (apicomplexa: adeleorina: hepatozoidae), infecting amietia quecketti (anura: pyxicephalidae). | blood smears prepared from the peripheral blood of 20 wild caught amietia quecketti (boulenger) from the north-west university botanical gardens, north west province, south africa, were examined for the presence of haemogregarines. a haemogregarine species comparative in morphology, host and geographical locality to that of haemogregarina theileri laveran, 1905 was detected. the original description of h. theileri was based solely on frog peripheral blood gamont stages. later, further parasite s ... | 2014 | 25185400 |
