Dobrovolskij maintains the tra- tion of monographs devoted to detailed coverage of digenetic tr matodes in the tradition of B. Dawes (1946) and T. A. Ginetsinskaya (1968). In this - spect, the book is traditional in both its form and content. In the beginning (Chapter 1), the authors provide a consistent analysis of the morphological features of all life cycle stages. Importantly, they present a detailed char- terization of sporocysts and rediae whose morphological-functional orga- zation has never been comprehensively described in modern literature. The authors not only list morphological characteristics, but also analyze the functional significance of different morphological structures and hypothesize about their evolution. Special attention is given to specific features of m- phogenesis in all stages of the trematode life cycle. On this basis, the authors provide several original suggestions about the possible origins of morp- logical evolution of the parthenogenetic (asexual) and the hermaphroditic generations. This is followed by a detailed consideration of the various m- phological-biological adaptations that ensure the successful completion of the complex life cycles of these parasites (Chapter 2). Life cycles inherent in different trematodes are subject to a special analysis (Chapter 3). The authors distinguish several basic types of life cycles and suggest an original interpretation of their evolutionary origin. Chapter 4 features the analysis of structure and the dynamics of trematode populations and is unusual for a monograph of this type.

Book excerpt: Digenetic trematodes constitute a major helminth group that parasitize humans and animals, and are a major cause of morbidity and mortality. The diseases caused by trematodes have been neglected for years, especially as compared with other parasitic diseases. However, the geographical limits and the populations at risk are currently expanding and changing in relation to factors such as growing international markets, improved transportation systems, and demographic changes. This has led to a growing international interest in trematode infections, although factors such as the difficulties entailed in the diagnosis, the complexity of human and agricultural practices, the lack of assessments of the economic costs or the limited number of effective drugs are preventing the development of control measures of these diseases in humans and livestock. In-depth studies are needed to clarify the current epidemiology of these helminth infections and to identify new and specific targets for both effective diagnosis and treatments. The main goal of this book is to present the major trematodes and their corresponding diseases in the framework of modern parasitology, considering matters such as the application of novel techniques and analysis of data in the context of host-parasite interactions and to show applications of new techniques and concepts for the studies on digenetic trematodes. This is an ideal book for parasitologists, microbiologists, zoologists, immunologists, professional of public health workers, clinicians and graduate and post-graduate students.

Available in PDF, EPUB and Kindle. Book excerpt: Coral disease is quickly becoming a crisis to the health and management of the world’s coral reefs. There is a great interest from many in preserving coral reefs. Unfortunately, the field of epizootiology is disorganized and lacks a standard vocabulary, methods, and diagnostic techniques, and tropical marine scientists are poorly trained in wildlife pathology, veterinary medicine, and epidemiology. Diseases of Coral will help to rectify this situation.

This book was released on 1975 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven species of fresh water fishes belonging to three different families and two species of snails from Ritner Creek, Polk County, Oregon were surveyed for adult and larval trematodes. A total of seven species of trematodes representing four families was recovered from the intestine of the fishes. Of these, at least two were under scribed new species. The trematodes were described and their taxonomy discussed. The stream snails, Oxytrema silicula and Flumenicola virens, were found to harbor at least 17 apparent species of larval trematodes. Five of these were described from the snails for the first time. A check-list of cercariae known to infect O. silicula and F. virens in the Pacific Northwest was presented. Life histories of five of the trematodes .encountered during the surveys were studied. The experimental life cycle of Apophallus donicus Skrjabin and Lindtrop, 1919 was completed. The cercaria, of the pleurolophocercous group, was found in F. virens, while the metacercaria encysted in a number of fresh water fishes. The life cycle of Plagioporus siliculus Sinitsin, 1931 was demonstrated for the first time. The cotylomicrocercous cercaria developed in sporocyst in O. silicula and penetrated crayfish, Pacifastacus lenuisculus to encyst in the abdominal muscles. The experimental definitive host used was the rainbow trout. A single adult Echinochasmus milvi Yamaguti, 1939 was recovered from a duck fed echinostome cysts found naturally in the gills of blackside dace, Rhinichthys osculus nubilus and redside shiner, Richardsoni balteatus hydrophlox. This constituted the third record of the trematode in the Pacific Northwest. The cercaria of E. milvi was believed to be Cercaria gorgonocephala Ward, 1916, which Martin (1968) redescribed from O. silicula. Two other macrocercous cercariae--one aggregating but albino while the other nonaggregating-- were also found in O. silicula, The body of these cercariae was identical to that of C. gorgonocephala. The taxonomic relation of the three cercariae was discussed. The partial life cycle of a new monorchiid trematode from the torrent sculpin, Cottus rhotheus, was presented. The natural secondary intermediate host was found to be lampreys, both brook (Lampetra richardsoni) and Pacific (L. tridentata). The first intermediate host is still unknown. The partial life cycle of another new trematode, an Echinochasmus sp., was also reported. The adult was obtained from a duck experimentally fed small cysts in the gills of blackside dace. The first intermediate host is unknown.
