Parasitological research today focused on studying protozoan parasites infecting fish especially myxosporidian and microsporidian parasites which cause adverse effects on the fish health causing high losses in fish production. Also the presence of Heavy infections with muscle-invading species destroy the texture of the fish flesh making it unmarketable. Morphological description of these parasites help in the exact determination of their taxonomy which may aid with the molecular tools in the development of anti substances against these parasites. The present book described some of these...

Helminthosis is the disease caused by the presence of helminth parasites within or outside the gastrointestinal tract of an individual. All species of animals can be infected with helminth parasites. The infection usually is more severe in the very young and the very old or immuno compromised individuals. Some adult animals can thrive fairly well while infected with some helminth parasites without showing obvious clinical signs while the vast majority suffer reduced productivity under heavy worm burdens. It appears some breeds of animals are more resistant to certain helminth parasites than...

Fish are well known to act as direct or indirect carriers of different zoonotic pathogens including parasites, viruses, bacteria and fungi. Parasitic infection is one of the most important problems facing fish breeding and production at commercial scales. So the most important reason for studying fish parasites is to study the relationships of these parasites to fishes, animals and man and also to understand some human health problems.The name "monogenea" means born once, and refers to the simple life cycle. In heavy infections, they can kill captive fish and occasionally wild ones.Gillworms...

Parasitology today focused on studying parasites infecting fish. Parasitic infestation is one of the most important problems facing fish breeding and production. All fish carry pathogens and parasites. Among fish parasites, especially ectoparasites, protozoa occupy a very important and dangerous group that causes severe economic losses and mortalities in freshwater pisciculture. Also, monogenetic trematodes of freshwater fishes could be considered as one of the most prevalent diseases affecting skin and gills, which included irritation, severe destruction of the gills, impaired breathing as...

Monogenean parasites of freshwater fish could be considered as one of the most prevalent diseases affecting skin and gills, which included irritation, severe destruction of the gills, impaired breathing as well as severe losses too. They are the most abundant ectoprasitic flukes of fish, with greater diversity of species occurring in tropics than in the temperate regions of the world. They spend their entire life cycle as parasites on gills and skin of fish, hold to the fish by the use of hooks and attachment organs at the posterior end.This study investigates the prevalence of these...

Reptiles of different taxonomic groups from different geographical regions all over the world were found to be naturally infected with a widely distributed rang of parasites. These parasites can be divided into endoparasites and ectoparasites . Endoparasites include Protozoa, and many helminthes. Protozoa are the most dangerous group that probably causes various diseases in reptiles, even moderate infection of these organisms in small reptiles may cause fatal diseases.The present study aimed to survey some of the parasitic protozoans and metazoans infecting many species of reptiles collected...

Protein deficiency is one of the major global challenges facing the third world today. In Egypt, the continuous increase in human population requires more food production to meet the consequent increasing demands. With the increasing demands for animal protein, the poultry sources were expensive and insufficient. Fish are considered to compensate the continuous lack of such element due to its comparatively low price. Therefore, more attention is being now focused on the development of the natural fish resources in general and aquaculture in particular in order to compensate for both...
