Environment & Ecology JULY Week-1

Nipah virus The Nipah virus infection is a newly emerging  zoonosis , that is, a disease transmitted from animals to humans  as stated by the WHO . The virus belongs to a new genus termed Henipavirus (subfamily Paramyxovirinae). It was first reported in 1998 at  Kampung Sungai Nipah  village, Malaysia. So virus is named after this village. The natural host of the virus are  fruit bats (Pteropus giganteus)  belonging to the family Pteropodidae.  In 2004, humans were affected after eating the date palm contaminated by infected fruit bats. Pigs can also act as intermediate hosts. Natural host  are those animals in which pathogens reside naturally and not infecting them. Here they grows upto a certain stage of their life cycle. Intermediate hosts  are those in which pathogens reside and not causing harm to them and here they are in inactive state i.e not growing further. Primary host  are those in which pathogens...

Parasitic adaptation of Taenia

Taenia Parasitic adaptations Tapeworms live as internal parasites and they have to make several adjustments for the same. The following are few of the adaptations made by these tapeworms to make their life easy in their hosts. Presence of enzymatic resistant covering A hard covering called as tegument covers the body of these tape worms. Tegument is enzyme resistant and it protects all the internal organs from the digestive actions of the alkaline fluids of the host. On the other hand tegument is permeable to water and other nutrients. Absence of locomotory organelles This parasite lacks organs for locomotion. As there is no need for any locomotory organs both the adult and larval forms lack cilia or flagella. Osmotic pressure The osmotic pressure inside the body is higher than that of the surrounding host tissue or fluid. This helps the parasite to reside conveniently in the host body. Presence of hooks and suckers for attachment For the attachment purpose a scolex...
