  • Oocyte mitochondria are highly dynamic and exhibit frequent fission and fusion. Those are clustered in the cytoplasm of previtellogenic oocytes which prepare for different synthetic activities for successful reproductive investment. In contrast, mitochondrial abundance is less in the male gametic lineage. The spermatocytes and the nurse cells in the testis have an unusual type of mitochondria, nebenkern which is formed by the fusions of number of mitochondria. A completely different type of mitochondrion is discovered in the flagellum of the spermatozoa.

  • Tularemia is a zoonosis caused by Francisella tularensis. Humans of any age, sex, or race are universally susceptible to this systemic infection. Tularemia is primarily a disease of wild animals and persists in contaminated environments, ectoparasites, and animal carriers. Human infection is incidental and usually results from interaction with biting or blood-sucking insects, contact with wild or domestic animals, ingestion of contaminated water or food, or inhalation of infective aerosols.

  • More than one hundred species of nematodes have been reported from upland and paddy rice in many countries (Tab. 1). Their frequency and importance are very variable and, in most cases the existence of a parasitic relationship with rice is probable but has not been demonstrated. Many species of root nematodes have been observed both in dry and irrigaftieldd s but very few species are found in both situations. Several surveys made by the authors in WAefrsitc a have shown that a relatively low number of species are adapted to permanently flooded conditions.

  • Control of ectoparasites on poultry creates additional exposure risks. High pressures sprays or dipping are often used in large commercial operations to treat birds for obligate ectoparasites such as the northern fowl mite. Aerosol and splash represent exposure risks for the applicator in both situations. Routes of entry may be oral, dermal or inhalation. Dipping represents the most significant risk to personnel since each bird must be handled to effectively treat the outbreak. A significant amount of splash occurs as birds are immersed and withdrawn from the dipping vat.

  • These pest infestations are infrequent and typically limited to breeding flocks or layers. Broilers and market turkeys are seldom if ever affected. Management of ectoparasites largely consists of whole flock treatments whenever infestations are detected by scouting birds and/or inspection of the structure and equipment (nest boxes, curtains, slats, cages). Other effective management techniques are not available. It is estimated that slightly more than 4 percent of breeder birds and layers are treated for ectoparasites each year.

  • This material is available as an emulsifiable concentrate. Treatments are most often used for fly control. Occasionally, dichlorvos is applied to control ectoparasites during cleanup routines following the sale of an infested breeder or layer flock. It is applied as either a space spray (0.001 pound of active ingredient per 1,000 cubic feet) or as a premise spray (0.01 pound of active ingredient per 1,000 square feet of surface area). Dichlorvos is occasionally used as a spot larvicide treatment for fly control at a rate of 0.002 to 0.
