An outbreak of S typhimurium in sheep and its consequences

An outbreak of Salmonella typhimurium in an upland sheep flock was characterised by rapid spread and heavy mortalities in ewes and young lambs. Clinical signs included diarrhoea and abortion. Abomasitis was the most striking and consistent post mortem lesion. Vaccination was the only control method that was apparently successful. Infection also occurred in the cattle, farm personnel, and a dog. Following the outbreak, pasture contamination and excreting cattle provided a reservoir of infection so that contamination of water courses and sporadic cases occurred over a year later.

Effect of briefly heating cyclophosphamide solutions

Solutions containing cyclophosphamide monohydrate were heated to 50 C, 60 C, 70 C and 80 C for 15 minutes and then assayed for potency. Solutions heated to 50 Cor 60 C did not change appreciably; those heated to 70 C and 80 C assayed at 90.2% and 77.5%, respectively, of initial potency. The values compared well with those calculated using the Arrhenius equation. It is concluded that warming vials of cyclophosphamide monohydrate after adding an aqueous vehicle (in order to achieve rapid dissolution) could decrease the potency of the final injectable product.
