“…gracilis, a lizard hemogregarine [8]; this may represent a biologic difference or a difference in technique, as oocysts may have ruptured during preparation for electron microscopy. These authors furthermore suggested that the bite of mosquitoes may be infective and is a likely natural route of infection for parasites such as H. aegypti [6]. However, the salivary glands of the mosquitoes were not examined and experimental transmission by bite was not achieved.…”

“…The gamont of H. canis possessed the nucleus, apical complex, micronemes, microbodies and ovoid granules, which appeared to be closely similar to those of H. mocassini, Haemogregarina magna and Babesiosoma stableri (Bashtar et al, 1984;Nadler and Miller, 1985;Paterson et al, 1988;Barta and Desser, 1986;Baker and Lainson, 1967 …”

“…Phase contrast microscopy appeared to indicate that the contrasty thick material was situated around the gamont. Little information is available on the fine structures of the capsules surrounding the gamonts of H. aegypti and H. mocassini (Bashtar et al, 1984;Nadler and Miller, 1985) . According to Nadler and Miller (1985) , the nonstaining capsule seen by light microscopy was considered to correspond to the electron-lucid space between the gamont pellicle of H. mocassini and the PVM.…”

Abstract:Gamont of Hepatozoon canis was observed by light, phase contrast and transmission electron microscopies.In a thin blood film the gamont was contained within a pale-blue capsule in the leukocyte. By phase contrast microscopy, the gamont was seen to be surrounded by a contrasty substance. Transmission electron microscopy revealed the presence of a parasitophorous vacuolar membrane, two layers in the pellicle of the gamont and a fine fibril-like structure surrounding the parasitophorous vacuole.

“…for which qualitative features and/or metrical data of their gamont and/or merogonic stages are available for comparison revealed high similarity at the molecular level both with our species and among themselves. These were H. domerguei Landau, Chabaud, Michel, Brygoo, 1970 (Han et al 2015); and H. aegypti Bashtar, Boulos, Mehlhorn, 1984from Spalerosophis diadema in Egypt (Abdel-Haleem et al 2018. Examining these species, Hepatozoon domerguei differs from H. bashtari n. sp.…”

“…Finally, H. aegypti differs in having slightly shorter gamonts (14 vs. 15.4) and merogonic stages with dimorphic meronts compared to monomorphic meronts in the case of H. bashtari n. sp. (Bashtar et al 1984).…”

Morphometric and molecular characterisation of Hepatozoon bashtari n. sp. in painted saw-scaled viper, Echis coloratus (Ophidia, Viperidae)

Hepatozoon species are the most widely known haemogregarines infecting a wide range of vertebrates, although predominately snakes. Herein, Hepatozoon bashtari n. sp., originally infecting the painted saw-scaled viper, Echis coloratus, in Saudi Arabia is described using both morphological features and molecular data from 18S rDNA sequences. The overall prevalence of infection was 60% (9/15) with parasitaemia ranging from 52 to 60%. Gamonts were entirely intraerythrocytic and were observed to cause considerable hypertrophy within the host cell. The mean size of mature gamonts was 15.4 × 3.3 μm. Merogonic stages were confined to the lung endothelial cells with monomorphic meronts. The average size of mature meronts was 32 × 12 μm and they were estimated to produce 13-16 merozoites each. The phylogenetic tree generated from SSU rDNA sequences revealed that Hepatozoon bashtari sp. n. clusters with the vast majority of other Hepatozoon species infecting snakes, lizards and geckos in various regions of the world, which would appear to support the hypothesis of prey-predator transmission of the genus Hepatozoon. Through a combination of morphological comparison with closely related Hepatozoon spp. and 18S rRNA gene sequence analysis, it is possible to confirm Hepatozoon bashtari sp. n. as a new species.
