All the immunized BALB/c mice failed to generate neutralizing antibodies against the New Guinea C laboratory (NGC-lab) strain of dengue virus type 2. scientific research as reference values for mice from animal facilities. Our obtained data may suggest that the treatment of EAC cell bearing Swiss albino mice with C. album leaf extract inhibited the growth of tumor cells by the induction of apoptosis. Mortality at 60 mg/kg diazepam was only 10%. Now over 200 generations from New York in 1920, BALB/c mice are distributed globally, and are among the most widely used inbred strains used in animal experimentation. The BALB/cJ substrain is susceptible to Listeria , all species of Leishmania , and several species of Trypanosoma , but is resistant to experimental allergic orchitis (EAO). Swiss mice are highly resistant to Leishmania infections in concordance with observed response in human F cross-breed between susceptible BALB/c and resistant Swiss mice infected with Leishmania major exhibit an intermediate phenotype for lesion sizes and type 1 cytokines but show low level of total IgG antibodies BALB/c 3T3 cell lines are highly disposed to transformation in tissue culture by the .
