RESUMO

BACKGROUND: Shigella spp. are common enteric pathogens in captive non-human primates. Treatment of symptomatic infections involves supportive care and antibiotic therapy, typically with an empirical choice of antibiotic. METHODS: Twenty-four clinically ill, Shigella PCR-positive animals were randomly assigned to one of four treatment groups: single-dose ceftiofur crystalline free acid (CCFA), single-dose azithromycin gavage, a 5-day tapering azithromycin dose, or 7-day course of enrofloxacin. We hypothesized that all antimicrobial therapies would have similar efficacy. RESULTS: Animals in all groups cleared Shigella, based on fecal PCR, and had resolution of clinical signs 2 weeks after treatment. Eight out of nine clinically ill and PCR-positive animals tested negative by fecal culture. CONCLUSIONS: Single-dose CCFA, single-dose azithromycin, and a 5-day tapering course of azithromycin all performed as well as a 7-day course of enrofloxacin in eliminating Shigella infection. Fecal PCR may be a better diagnostic than culture for Shigella.

RESUMO

BACKGROUND: Food avoidance secondary to disease or stress can lead to weight loss and rapid deterioration of clinical condition in the common marmoset (Callithrix jacchus). Currently, there are no data supporting the use of any pharmaceuticals as an appetite stimulant in this species; however, benzodiazepines are frequently used for this purpose in other species. METHODS: Six marmosets were used in a crossover study design to evaluate the benzodiazepine midazolam as an appetite stimulant and anxiolytic. Total food intake (TFI) and latency to eat (LTE) were measured following administration of oral and injectable midazolam in non-anxious and anxious states. RESULTS: Injectable midazolam increased TFI and decreased LTE in anxious marmosets, but had no effect in non-anxious animals. Oral midazolam had no effect on appetite in either state. CONCLUSIONS: Injectable midazolam may be an effective treatment for anxiety-induced inappetence in marmosets. Individual response to both oral and injectable midazolam may vary.
