Background: Pyelonephritis can lead to renal scar. Objective: To evaluate the effects of betamethasone in preventing renal scarring in rat model of pyelonephritis. Methods: Sixty three female Sprague-Dawley rats were divided into seven groups. Group A was the control. Mannose-sensitive E coli was directly inoculated into the left kidney exposed under general anesthesia in groups C–G. Group B re...

Gestational outcome in a murine model of congenital enterovirus infection was evaluated. Pregnant mice were inoculated intravenously with Theiler's murine encephalomyelitis virus (TMEV), a murine enterovirus, or with BHK 21 cell lysate (control) at 6-7 days of gestation (early) and sacrificed 6 or 12 days later, and their placentas and fetuses were studied. High rates of gross and histologic ab...

The combined effects of inoculation level (4 or 8-fold compared to standard inoculation) and sequence (standard inoculation before fermentation and 3-fold inoculation at the end of fermentation=1+3, Two-fold inoculation before fermentation and the same at the end of fermentation=2+2, 2+6, 4-fold before fermentation=4, 4+4, and 8) of culture inoculum containing probiotics on biochemical and micr...

Five-week-old birds of resistant (N) and susceptible (P) genetic lines were inoculated with the JM strain of Marek's disease (MD) virus. MD occurred only in P-line birds; one-third had died by the end of the experiment (63 days after inoculation). Sera were examined for antibodies (precipitating, virus neutralizing,and fluorescing), and immunoglobulins were measured. Antibodies were associated ...
