Interferon Induction by the Psittacosis Agent in Guinea Pig Leukocyte Cultures

Guinea Pig Leukocyte Cultures

High titers of interferon were induced by the psittacosis agent in guinea pig leukocyte cultures. Optimal yields of interferon were produced from freshly prepared guinea pig leukocyte cultures containing 4 x 106 cells per ml inoculated with a psittacosis/cell multiplicity of 1.0 and incubated at 35 C for 24 hr. Leukocytes obtained from 2to 4-month-old guinea pigs produced 20 times more interfer...

Some observations on the feeding of the guinea pig

Karyotype of Hairless Guinea pig

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...
