Isolation of Salmonella roan for the first time in India

The isolation of Salmonella roan for the first time in India is reported.

Isolation of bile from fish and identification by thin layer chromatography

The paper deals with the collection of gall bladders, isolation of bile and identification of the constituents of the bile salts from different fishes. The yield of bile contents from fresh water fishes rohu, mrigal and catla was compared with that from marine fishes seer, tuna, shark and sardine. Considerable variation in yield was showed between marine and fresh water fish as well as between the species in both groups. It ranged from 0.04 to 0.06% of the body weight of fish in calla, mrigal and rohu. The bile constituents from rohu and mrigal were analysed by thin layer chromatography. The result showed that bile of rohu and mrigal contains mainly taurine derivative of lithocholic acid.

Isolation of Salmonella braenderup (6, 7:e, h:e, n, z (sub15)) from Mussel meat

A brief account is given of the morphology, biochemistry and serology of Salmonella braenderup isolated from mussel meat, obtained from fish markets in Calicut, India. Possible implications regarding human salmonellosis are also considered.

Isolation and culture in artificial media of Lagenidium from Penaeus monodon larvae

Fungal infection of P. monodon larvae is a problem in hatchery operations. The fungus, which attacks the nauplius to postlarval stages and causes up to 100% mortality, has been tentatively identified as belonging to the genus Lagenidium . This pathogenic organism has recently been isolated and cultured. A description is given of the fungus, and features of its biology and pathology are discussed.

Isolation of Salmonella agona (4, 12:f, g, 5:-) from commercial frozen boiled clam meat

Details are given of the morphological, biochemical and serological characteristics of a specimen of Salmonella agona isolated from a sample of frozen boiled clam meat (Villorita cyprinoides) processed in a factory at Cochin. Possible association of this serotype with human salmonellosis is considered briefly.

Isolation and structure elucidation of nortriterpenoids from Schisandra rubriflora

Seven new highly oxygenated nortriterpenoids, rubriflorins D-J (1-7), were isolated from the leaves and stems of Schisandra rubriflora, and their structures were elucidated on the basis of extensive analysis of spectroscopic data. These new compounds feat

A new lectin from the sea worm Serpula vermicularis: Isolation, characterization and anti-HIV activity

A GlcNAc-specific lectin was isolated from the sea worm Serpula vermicularis (SVL) (Annelida) and purified by ion-exchange, affinity and gel permeation chromatography. SVL was a homotetrameric protein with native molecular mass of about 50 kDa, and consis

Isolation and characterization of miscellaneous terpenoids of Schisandra chinensis

Two new bisnortriterpenoids with 18-norschiartane skeleton, wuweizidilactones G (1) and H (2), four new highly oxygenated nortriterpenoids based on a schisanartane skeleton, schindilactones D-G (3-6), a pre-schisanartane skeleton, pre-schisanartanin B (7)
