A Stabilizer of Antigenic Phases in Salmonella Abortus-Equi.

Some Observations on the Non-specifically Enhanced Resistance of Mice against Intraperitoneal Infection with Salmonella Abortus-equi

Antibacterial effect of thiazole derivatives on Rhodoccocus equi, Brucella abortus, and Pasteurella multocida

Background: Rhodoccocus equi, Brucella abortus, and Pasteurella multocida are important veterinary bacterial pathogens that in recent years have been resisted to current antibiotics, and this problem threats the livestock industry. To control this resistant microorganisms, use of new antibacterial compounds, such as thiazole derivatives, in veterinary is necessary. OBJECTIVES: In this study, an...

The occurrence of three flagellar phases in Arizona serotypes.

Since Andrewes (1922) described •gspecific•h and •gnonspecific•h flagellar antigens in several Salmonella types, the diphasic state has been recognized in hundreds of Salmo nella serotypes and has been recognized also in the Arizona group (Edwards and West, 1945). Similar variations have been found in the Escherichia freundii (Citobacter) group by Edwards (1946), in the Hafnia group by Deacon (...

Studies on the antigenic patterns of bacterial flagella.

It is well known that there are two kinds of Salmonella organisms in respect of flagellar antigens; the one is monophasic and the other is diphasic. The distinction is based upon whether organisms form colonies showing uniform behavior in respect of flagellar agglutinability or dissociating into two kinds of colonies different from each other. Further consideration reveals the existence of two ...

Phase I trial of intravenously administered endotoxin (Salmonella abortus equi) in cancer patients.

We report a phase I study in cancer patients being treated with i.v. bolus injections of highly purified lipopolysaccharide (LPS) Salmonella abortus equi. Twenty-four patients with disseminated cancer received escalating doses of LPS at 2-week intervals. Dose escalation was performed in six dose levels treating 3-6 patients at each level. Dose levels 1 and 2 consisted of 0.15 and 0.3 ng/kg, res...
