Studies on Natural Antibodies to Gram-negative Bacteria
A study was made of the origin, occurrence, and properties of natural antibodies to Gram-negative bacteria in the normal serum of several species. Antibody was measured by a procedure based on the bactericidal reaction carried out under conditions in which activity was a function of the amount of antibody contributed by the test serum. Antibody to seven genera of the family Enterobacteriaceae w...
متن کاملEffect of antibacterial steroid alkaloids from three Lorestan medicinal plants on gram-negative/positive bacteria
Background: Alkaloids are a group of nitrogen- containing natural compounds derived from a variety of sources including bacteria, fungi, marine organisms and plants. Materials and methods: Fruits, stem or leaves were collected from the Zagros highlands around Azna or Khoramabad city, dried and powdered before being extracted in a soxhalet apparatus. The extract was filtered and concentrated u...
متن کاملAntibacterial Activity Studies of Salvia Mirzayanii and Salvia Atropatana against Six Standard Gram Positive and Gram Negative Bacteria
In this study antimicrobial effects of Salivia mirzayanii and Saliva atropatana were evaluated against six gram-positive and gram-negative bacteria by immersion bioautography, cylinder plate and tube dilution methods separately. In bioautography method, essential oils of Salvia mirzayanii and Salvia atropatana were separated on silicagel TLC plates by toluene-ethyl acetate (93-7). In cylander p...
متن کاملTransferrin-iron uptake by Gram-negative bacteria.
Members of the families Neisseriaceae, Pasteurellaceae and Moraxellaceae are capable of transferrin-iron acquisition in the absence of siderophore production. They do so via expression of a bi-partite receptor composed of two dissimilar proteins, TbpA and TbpB. Both proteins are surface exposed, iron-regulated and capable of binding transferrin. However, other physiochemical, antigenic, and imm...
متن کاملLysis of gram-negative bacteria by serum.
The antibacterial property of serum, first reported by Nuttall in 1888, has attracted many investigators and an extensive literature has accumulated. The sera of most mammals tested have been found to possess bactericidal activity, but a notable exception is the mouse, whose serum, apparently through lack of complement, is unable to kill any of a number of bacterial strains which are sensitive ...
