Maternal pheromone in Rattus norvegicus.
A replication was undertaken of the finding that rat pups between 14 and 28 days of age will approach an attractant (maternal pheromone) contained in the excrement of lactating female rats. Preweaning pups from three strains of Rattus norvegicus (hooded PVG/C, Wistar, and Sprague-Dawley) were tested under different apparatus conditions, with different stimuli, and with different pretest experience. Despite attempts to maximize the attractant olfactory properties of stimulus material no clear evidence of maternal pheromone could be demonstrated. The use of olfactory cues, and an ability of rat pups to discriminate maternal odor, were shown. But such behavior falls short of that which would merit the use of the term pheromone.

Encephalitozoonosis (nosematosis) causing bilateral cataract in a rabbit.
Bilateral cataract due to a microsporidan believed to be Encephalitozoon cuniculi (also called Nosema cuniculi) is described as an incidental finding in a laboratory rabbit. The route of infection and the significance of the findings are discussed. This is apparently the first report of cataract due to this cause.
