Retrograde tracer injections in nucleus reuniens and the mammillary bodies:

A total of ten rats received retrograde tracer injections. In seven of these cases, two retrograde tracer injections were made, one directed at nucleus reuniens, the other at the mam-millary bodies (Table 1). In the three remaining cases only the injection directed at nucleus reuniens was successful. Different tracers were used, one in each site. The tracers used were fast blue (FB, SigmaAldrich, Gillingham, UK) and choleratoxin b (CTB, List Biological Laboratories Inc, CA; 1% solution in 0.05 M tris). Except for one CTB injection that was injected by iontophoresis, all retrograde tracers were injected mechanically at a rate of 20 nl/min via a 0.5 µl or 1.0 µl Hamilton pipette (Hamilton, Bonaduz, Switzerland). Individual injection volumes for mechanical injections were 50-60 nl. …

Test approach:

No standardized approaches are available to investigate anthrax seroprevalence in wildlife. Thus, samples were tested for antibodies against the anthrax protective antigen (PA, List Biological Laboratories Inc) using an in-house ELISA and an in-house Western Blot and for antibodies against anthrax lethal factor (LF, List Biological Laboratories Inc) using an in-house Western Blot. …

Induction and treatment of EAE:

EAE was induced in age-matched female mice with 300L of 300µg MOG emulsified in CFA containing 8mg/mL killed Mycobacterium tuberculosis via subcutaneous injection on day 0 and day 7, followed by the i.p. injection of 250ng pertussis toxin (list biological laboratories) on day 0, day 2, day 7, day 9¹³. Clinical scores (0, no symptoms; 1, limp tail; 2, partial paralysis of hind limbs; 3, complete paralysis of hind limbs or partial hind and front limb paralysis; 4, tetraparalysis; 5, moribund) were recorded daily. The mean score was noted for each mouse every day. …

Protocols in mice:

Six week-old female BALB/c mice (Charles River Laboratories, Saint Germain sur Arbresle, Rhne, France) were distributed in 5 groups (5 per group). Three groups were sensitized to EW by the intragastric administration of 5mg of EW on a protein basis and 10g of cholera toxin (CT, List Biologicals, Campbell, CA, USA), during 3 successive days on the first week and once per week for the subsequent 5weeks (Li et al., 2000). Sham-sensitized mice received CT and nave mice just received PBS. …
