Scientists have discovered a new family of limbless amphibians from northeast India with their ancient lineage traced to eastern and western parts of Africa, a relationship preserved from the time the southern continents broke up more than 150 million years ago.
Kerala-born Delhi University scientist S.D. Biju and co-researchers from India and Europe have reported their discovery in the latest issue of the Proceedings of the Royal Society of London B. They have named the new family as Chikilidae and the new genus as Chikila, deriving the name from the Northeast Indian tribal language of Garo.
Until this discovery, there were only nine known families of legless amphibians, also called caecilians, found across the wet tropical regions of Southeast Asia, India, Sri Lanka, parts of East and West Africa, the Seychelles and northern and eastern parts of South America. From morphological and DNA analyses, the researchers show that the new family had evolved independent of other species of caecilians starting from the time of the dinosaurs. Its closest relatives now live in Africa.

Influenza A detection by MDCK cell line

The influenza A (IA) virus is the principal cause of the outbreaks of flu. A large number of laboratories participate in the worldwide surveillance of influenza virus activity and contribute to the early recognition of newly emerging epidemic strains. Differentiation between influenza A and B viruses and determination of the subtypes of influenza A virus isolates are the first steps in the characterization of influenza viruses. This analysis is traditionally done by hemagglutination inhibition (HI) tests with specific antisera raised in ferrets, chickens, or sheep.
The diagnosis of Influenza A is largely clinical. Nevertheless, it is necessary to carry out some form of rapid antigenic diagnosis and the culture of respiratory samples to confirm the etiology of the respiratory disease and to determine the antigenic characteristics of the epidemic strains. Although the “gold standard” isolation technique is inoculation in embryonated hens’ eggs, the technical difficulties involved and …
