The Eye Fluke Philophthalmus Hegeneri (Digenea: Philophthalmidae)
Kuwait J. Sci. Eng. 3171) pp. 119-133, 2004 The eye ¯uke Philophthalmus hegeneri Digenea: Philophthalmidae) in Kuwait Bay J. ABDUL-SALAM, B. S. SREELATHA AND H. ASHKANANI Department of Biological Sciences, Kuwait University, P. O. Box 5969, Safat, Kuwait 13060 ABSTRACT The eye ¯uke Philophthalmus hegeneri Penner and Fried, 1963 was reared from cercariae developing in the marine snail Cerithium scabridum in Kuwait Bay. Infected snails released megalurous cercariae which readily encysted in characteristically ¯ask-shaped cysts. Adult ¯ukes were recovered from the ocular orbit of experimentally infected domestic ducklings inoculated with excysted metacercariae. The adult and larval stages of the ¯uke are described and compared with those of the other marine-acquired Philophthalmus species. The metacercaria of the Kuwaiti isolate of P. hegeneri diers from those of an American isolate from Batillaria minima in the Gulf of Mexico in the process of encystment, and metacercarial cyst shape resembles those of P. larsoni from a congeneric snail, C. muscarum, from Florida, suggesting a close relationship. The present record signi®cantly extends the known geographical range of P. hegeneri and implicates a new intermediate host. Keywords: Digenea; Metacercaria; Philophthalmus hegeneri; Cerithium scabridum; Kuwait Bay. INTRODUCTION Members of the genus Philophthalmus Loose, 1899 7Philophthalmidae Travassos, 1918) are widely distributed eye ¯ukes of aquatic birds. The life cycle of Philophthalmus has been established through studies on species utilizing freshwater or marine snails as intermediate host 7Fisher & West 1958, Penner & Fried 1963, Howell & Bearup 1967, McMillan & Macy 1972, Dronen & Penner 1975, Radev et al. 2000). Although more than 36 Philophthalmus species have been reported, only P. -

Supporting Text Recursions. We developed a model to investigate the evolution of ploidy levels in the presence of host-parasite interactions between a focal and nonfocal species. The focal species is assumed to have two loci, a ploidy modifier locus with alleles C1 and C2 and an interaction locus with alleles A and a. Thus there are four haploid gamete types in the focal species: AC1 with frequency X1, aC1 with frequency X2, AC2 with frequency X3, and aC2 with frequency X4. The modifier locus influences ploidy levels by altering the timing of meiosis; diploid zygotes of genotype CiCj have a probability, dij, of undergoing meiosis late in life, thus experiencing host-parasite selection as a diploid, versus early in life, thus experiencing selection as a haploid (Fig. 2). The nonfocal species is assumed to be a sexual diploid, having only a brief haploid stage, although results derived with a haploid nonfocal species were similar. For clarity, we assume that the A locus in the focal species interacts with a B locus in the nonfocal species, with alleles B and b. Note that Table 1 differs from this convention by referring to alleles in both species as A and a. We use a different notation here to avoid additional subscripts in the equations. The frequencies of alleles are denoted by pA, pa, pC1, and pC2 in the focal species and pB and pb in the nonfocal species, all measured at the gamete stage of the life cycle (Fig. 2). Also measured at this stage is D = (X1 X4 - X2 X3), the disequilibrium between the modifier and selected loci in the focal species. -

P a R T . III. STUDIES on Hepatozoon in SOME SNAICES
PART. III. STUDIES ON HepatOZOOn IN SOME SNAICES 140 INTRODUCTION Hepatozoon is an intra-corpuscular non-pigmented parasite of vertebrates. Levine,et al»,(1980) placed Haemogregarina Danilewsky, 1885, Hfepatozoon Miller, 1908 and Karyolysus Labb^,1894 in three distinct: families viz,, Haemogregarinidae Leger,1911,„ Hepatozoidae WenYon,1926 and Karyolysidae Wenyon,1926 of the suborder Adeleina under the Class Sporozoea, The characteristic features of the genus Haemogregarina Danilewsky,1885 has • been given in Part II, page nimber. 151, Genus Hepatozoon Miller,1908 is characterised by the presence of schizogony cycle in cells- of the internal organs ( liver, spleen, kidney, lung and bone- marrow etc. ) of vertebrate hosts. At an interval of several generations, some merozoites enter: erythrocytes or: leucocytes as in the case may be, and develop into gametocytes. Sporogony stages are knovm to occur in arthropod hosts. Zygote develops into oocyst stage. These increase in size and become ^quite large. Oocysts contain num.erous sporoblasts and ultjjnately to sporozoites. Genus Karyolysus Labbe'', 1894 is distinguished from Haemogregarina and Hepatozoon' on the basis of the following characters. 141 Schizogony occurs in the endothelial cells of the blood vessels and the gametocytes enter the red blood corpuscles of vertebrate hosts., Sporogony occurs in invertebrate host (mite) v/here large oocyst deveops containing sporoblasts. These escape from oocyst as motile vermicules and enter the egg in v/hich these become sporocysts within v/hich sporozoites are-: developed. The above three genera have been reported to occur in the peripheral blood of cold-blooded vertebrates, Gametocytes-of these genera do not always provide a reliable clue to their generic differentiation. -

Sao Paulo 52(6):323-327, November-December, 2010 doi: 10.1590/S0036-46652010000600007 Melanoides tuberculata AS INTERMEDIATE HOST OF Philophthalmus gralli IN BRAZIL Hudson Alves PINTO & Alan Lane de MELO SUMMARY Melanoides tuberculata that naturally harbored trematode larvae were collected at the Pampulha dam, Belo Horizonte (Minas Gerais, Brazil), during malacological surveys conducted from 2006 to 2010. From 7,164 specimens of M. tuberculata collected, 25 (0.35%) were infected by cercariae, which have been morphologically characterized as belonging to the Megalurous group, genus Philophthalmus. Excysted metacercariae were used for successful experimental infection of Gallus gallus domesticus, and adult parasites recovered from the nictitating membranes of chickens were identified asPhilophthalmus gralli. This is the first report ofP. gralli in M. tuberculata in Brazil. KEYWORDS: Philophthalmus gralli; Melanoides tuberculata; Eyefluke; Brazil; Snail intermediate host. INTRODUCTION (over minimum intervals of one month), conducted from 2006 to 2010 at Pampulha dam, an eutrophic artificial water body with an area of 260 Melanoides tuberculata (Müller, 1774), an exotic species of hectares and a total water volume of 12 million m3 located in the northern snail introduced in Brazil in the late 1960s35, has been found in region of the city of Belo Horizonte, in the state of Minas Gerais, Brazil. several Brazilian states9.

The diagnosis of coccidiosis, species description and systematics, are all dependent upon characterization of the oocyst. Therefore, this review aimed to the provide a critical overview of the methodologies, advantages and limitations of the currently available morphological, morphometrical and molecular biology based approaches that may be utilized for characterization of these important structures. -
