Scientists use a variety of methods for making vaccines. They are based on research on the diseases (caused by bacteria or viruses) the vaccine is designed to be able to prevent, like the way that germs infect cells, and the way the immune system responds to it.
Vaccines have so far held the center position in efforts to stop viruses. They are inexpensive and secure, and the protection can last for a long time. But some viruses because of a number of reasons, aren’t compatible with this method like retroviruses, influenza as well as rhinoviruses and arboviruses.
Introduction In our daily life, we are thinking about Viral Infection and their symptoms, when we get infected by any infectious virus such as the flu or the chickenpox. But ever you ask, what’s actually happening in your body when you have been infected by a virus? In biology, viral infection means viruses are started … Read more
The virus uses the host’s complete system for protein translation because they lack translational machinery. Hence, the Baltimore classification system is based on this machinery how viruses use the host mechanism. Messenger RNA (mRNA) is the main focus of this classification system. In the beginning, there were six classes of viruses in Baltimore classification system … Read more
Viroids Definition Viroids Structure: Replication of Viroids or Infection of Viroids Viroid RNA replicates autonomously and spreads within the host by recruiting host proteins. There are three enzymes that help in RNA replication such as RNA pol. II, RNAase and RNA ligase. Viroid RNA don’t code for any plant protein and they lack AUG initiation … Read more
Diagnosis of viral infections Importance of Viral Diagnosis The Viral diagnosis will be particularly helpful in different clinical situations such as; Diagnosis Methods 1. The Direct Examination of Specimen The direct method is accomplished by these following processes; 2. Indirect Method or cell cultures (Virus Isolation) The Cytopathic Effect (CPE) is present in both HSV … Read more
What is Cysticercosis? Clinical manifestations of Cysticercosis Cysticercosis is a parasitic infection caused by the larval stage of the tapeworm Taenia solium. The clinical manifestations of cysticercosis depend on the location of the cysticerci (larval stage) within the body. It’s worth noting that not all patients with cysticercosis will experience symptoms. Asymptomatic cysticercosis is often … Read more

Fasciola Hepatica Life Cycle of Fasciola Hepatica Fasciola hepatica completes its life cycle in two hosts. The definitive or primary host is a sheep or cow, while the intermediate or secondary host is a small of the genus Limnaea. Its life cycle consists of a number of larval stages that reproduce asexually (polyembryony). Copulation, Fertilization … Read more
Strongyloides stercoralis Distribution of Strongyloides stercoralis Habitat of Strongyloides stercoralis Morphology of Strongyloides stercoralis There are two different species of Strongyloides stercolaris: parasitic and free-living. The females are easily found during the parasite phase, but not the males. Parasitic female Parasitic males Eggs Larva The larva of S. Stercoratis is of two types: 1. Rhabditiform larva (first stage larva) 2. … Read more
