Purification and Characterization of Two Proteins from Culture Filtrates of Mycobacterium tuberculosis H(37)Ra Strain.

Infection and immunity

Daniel TM, Ferguson LE.
PMID: 16557708
Infect Immun. 1970 Feb;1(2):164-8. doi: 10.1128/iai.1.2.164-168.1970.

Two proteins have been purified from culture filtrates of Mycobacterium tuberculosis, H(37)Ra strain by a procedure combining gel filtration, diethylaminoethyl (DEAE)-cellulose chromatography, and zone electrophoresis. The two proteins are similar in molecular weight but differ slightly in charge. The...

Immunity to enteric infection in mice.

Infection and immunity

Collins FM.
PMID: 16557723
Infect Immun. 1970 Mar;1(3):243-50. doi: 10.1128/iai.1.3.243-250.1970.

Specific pathogen-free CD-1 mice infected orally with sublethal doses (10(4) to 10(6) viable organisms) of Salmonella enteritidis rapidly developed extensive bacterial populations in the liver, spleen, and mesenteric lymph nodes. Although the pathogen did not multiply extensively in the...

Interaction of Gram-Negative Bacteria with the Lysosomal Fraction of Polymorphonuclear Leukocytes II. Changes in the Cell Envelope of Escherichia coli.

Infection and immunity

Friedberg D, Friedberg I, Shilo M.
PMID: 16557734
Infect Immun. 1970 Mar;1(3):311-8. doi: 10.1128/iai.1.3.311-318.1970.

Interaction of lysosomal fraction with Escherichia coli caused damage to the cell envelope of these intact cells and to the cytoplasmic membrane of E. coli spheroplasts. The damage to the cytoplasmic membrane was manifested in the release of 260-nm...

Solubilization and Characterization of a Protective Antigen of Erysipelothrix rhusiopathiae.

Infection and immunity

White RR, Verwey WF.
PMID: 16557746
Infect Immun. 1970 Apr;1(4):387-93. doi: 10.1128/iai.1.4.387-393.1970.

A particulate fraction of Erysipelothrix rhusiopathiae cultures has been subjected to butanol extraction and treatment with surface-active agents in an attempt to solubilize a protective antigen. The particulate fraction was partitioned into the butanol layer but was not solubilized....

Comparative Hemolytic Activity of Vibrio parahaemolyticus and Related Vibrios.

Infection and immunity

Twedt RM, Novelli RE, Spaulding PL, Hall HE.
PMID: 16557747
Infect Immun. 1970 Apr;1(4):394-9. doi: 10.1128/iai.1.4.394-399.1970.

The hemolytic activities of 91 strains of Vibrio parahaemolyticus isolated from human diarrheal stools, sea fish, and sea water; 21 suspected V. parahaemolyticus cultures isolated from wound infections; 14 nonpathogenic marine vibrios; and 21 V. parahaemolyticus isolated from moribund...

Antigens of mycobacterial cell walls.

Infection and immunity

Wong KH, Pickett MJ, Froman S.
PMID: 16557748
Infect Immun. 1970 Apr;1(4):400-7. doi: 10.1128/iai.1.4.400-407.1970.

Three antigenic fractions from the cell walls of eight strains of mycobacteria were studied. Isolation and purification of these antigens were effected by enzymatic digestions, differential and sucrose gradient centrifugations, dialyses, and column chromatography. Two of the fractions were...

Role of Glycolipids and Phosphatidylglycerol in the Serological Activity of Mycoplasma pneumoniae.

Infection and immunity

Razin S, Prescott B, Caldes G, James WD, Chanock RM.
PMID: 16557749
Infect Immun. 1970 Apr;1(4):408-16. doi: 10.1128/iai.1.4.408-416.1970.

Mycoplasma pneumoniae lipids were fractionated by combined silicic acid and diethylaminoethyl-cellulose chromatography. The lipid fractions were tested for complement-fixing activity and for blocking of metabolism-inhibiting antibodies in human and rabbit antisera to M. pneumoniae. Thin-layer chromatography and carbohydrate analysis...

Antitoxic immunity in experimental cholera: observations with purified antigens and the ligated ileal loop model.

Infection and immunity

Finkelstein RA.
PMID: 16557759
Infect Immun. 1970 May;1(5):464-7. doi: 10.1128/iai.1.5.464-467.1970.

Rabbits immunized with purified antigens, choleragen and choleragenoid (cholera exo-enterotoxin and natural toxoid), were found to resist intra-intestinal challenge with a variety of strains of cholera vibrios. The resistance occurred in the absence of a significant antibacterial antibody response....

Cytopathic Effects and Ultrastructure of Mycoplasma agalactiae var. bovis (Donetta strain).

Infection and immunity

Hirth RS, Tourtellotte ME, Nielsen SW.
PMID: 16557787
Infect Immun. 1970 Jul;2(1):105-11. doi: 10.1128/iai.2.1.105-111.1970.

An electron microscopic examination of the pathogenic Donetta strain mycoplasma (tentatively Mycoplasma agalactiae var. bovis), in broth and cell cultures, revealed that this organism possessed considerable pleomorphism. A membranelined space occurred in a number of the organisms, and some...

Nature and Heterogeneity of the Antigens of Neisseria gonorrhoeae Involved in the Serum Bactericidal Reaction.

Infection and immunity

Glynn AA, Ward ME.
PMID: 16557815
Infect Immun. 1970 Aug;2(2):162-8. doi: 10.1128/iai.2.2.162-168.1970.

Sixty strains of Neisseria gonorrhoeae have been classified into four main groups according to their resistance to killing by human complement together with either normal human or immune rabbit antibodies. The rabbit antisera had been raised against 10 of...

Comparison of Chemical Components of Cell Walls of Brucella abortus Strains of Low and High Virulence.
