Effects Of Trypanosoma Musculi Kendall, 1906 Immune Serum On The Reproduction Of Trichinella Spiralis (Owen, 1835) Railliet, 1896 In Mice, Samuel L. Chafin
Effects Of Trypanosoma Musculi Kendall, 1906 Immune Serum On The Reproduction Of Trichinella Spiralis (Owen, 1835) Railliet, 1896 In Mice, Samuel L. Chafin
Loma Linda University Electronic Theses, Dissertations & Projects
The possible effects of ablastin, a reproduction-inhibiting antibody which is produced during the infection of the blood parasite, Trypanosoma musculi in the mouse, were investigated by fractionating the parasite into a supernatant fraction (designated as Group A test mice) and a pellet fraction (Group B test mice). These groups A and B mice were injected with the respective fractions, plus Freund’s Complete Adjuvant (FCA). Control mice were injected with FCA only. Sera from these three groups of mice were removed after the Group A and Group B mice were shown to be negative to T. musculi challenge, and Group A …
Effect Of Time And Diet On The Immune Status Of Mice Challenged With Herpes-Transformed Cells, Daila S. Gridley
Effect Of Time And Diet On The Immune Status Of Mice Challenged With Herpes-Transformed Cells, Daila S. Gridley
Loma Linda University Electronic Theses, Dissertations & Projects
Human Herpes simplex virus type 2 (HSV 2)-transformed Balb/c mouse cells (H238 cells) are malignant in Balb/c mice. The immune stratus of mice bearing H238 cell-induced tumors was studied and changes in immune response with time and with altered diet of the mice were measured.
In the experiments dealing with the status of immunity with time after tumor cell injection, mice were fed Purina Laboratory Chow (P.L.C.), injected with H238 cells, and sacrificed three to eight weeks post-injection. In the diet experiments, groups of mice were fed either P.L.C. or one of six equicaloric diets, consisting of low or high …
Non-Parental-Type Recombinants In Crosses Between Different Restriction-Modification Systems In Salmonella, Mary Ball
Loma Linda University Electronic Theses, Dissertations & Projects
Many new restriction-modification (R-M) system which are closely linked to serB and allelic to the hsdSB system of S. typimurium occur in different Salmonella serotypes. In PI transduction studies with these systems, recombinants were isolated which fell into one of three classes with reference to their specific restriction phenotype. Recombinants that restricted like the donor, recombinants that restricted like the recipient and recombinants that had lost the ability to restrict. This latter group having lost the recipient SB restriction without gaining the specific donor restriction and here called "zero recombinants,” were of special interest and were investigated.
Zero recombinants …
