are susceptible.³ Dermatophytosis can be found in dogs (most often puppies)‚ cats‚ cattle‚ sheep (common in show lambs)‚ goats‚ horses‚ swine‚ rodents‚ rabbits (most often in young ‚ newly weaned animals)‚ and birds.⁴ The condition is caused by fungi of several different species and not by parasitic worms. In pets‚ the fungus responsible for the disease survives in skin and on the outer surface of hairs.¹ They grow best in warm and humid environments and are‚ therefore‚ more common in tropical

Module 04 Homework Assignment Use the information presented in this module along with additional outside research to answer the questions: 1 Discuss the two methods of viral replication. The two methods of viral replication are done in animal viruses. The first method deals with DNA viruses and the second is RNA viruses. In the DNA virus‚ the viral DNA enters the nucleus of the host cell. Than it is transcribed into mRNA and leaves the nucleus into the cytoplasm. The early mRNA then translates

INTRODUCTION Mycorrhizal fungi are ubiquitous in terrestrial ecosystems‚ forming a symbiotic association with roots from the majority of plant species (Chen et al. 2005). These fungi benefit the plant by improving plant growth and mineral nutrition‚ tolerance to diseases and stresses such as drought and temperature fluctuation (Phosri et al. 2010‚ Reinhart
