Adverse reaction to procaine penicillin G in horses

Adverse reactions to intramuscular injections of procaine penicillin G are reported in 11 horses, five of which died. The clinical findings are presented and suggest central nervous involvement in most cases. Post mortem findings in one horse were consistent with anaphylaxis whereas in other cases the clinical findings, duration of treatment, speed of onset and subsequent completion of treatment supports diagnosis of an acute procaine toxicity syndrome.     

Further studies on the adjuvant effect of an interferon inducer (BRL 5907) on Newcastle disease and avian influenza inactivated vaccines.

Vaccination of fowls with inactivated Newcastle disease (ND) virus and avian influenza (AI) virus oil emulsion vaccines containing an interferon inducer (BRL 5907) produced an enhanced immunological response. The Newcastle disease vaccine containing BRL 5907 induced earlier protection to challenge than Newcastle disease vaccine by itself and also produced an increase immune response when administered to day-old maternally immune and susceptible chicks.     

Genetics of stem rust resistance in the durum wheat accession ‘Reichenbachii’

Summary Inheritance of seedling reactions to cultures of races TLM and MBCT of Puccinia graminis f.sp. tritici was studied in crosses of the resistant durum Reichenbachii with susceptible Marruecos 9623 and DZ04-118. The Chi-square test for goodness of fit was used to analyze segregating populations. Two independent recessive genes appeared to control resistance of Reichenbachii to both TLM and MBCT. Depending upon the cross, the two genes interacted cumulatively to condition immunity or higher levels of resistance than either parent conditioned singly. There was no evidence of maternal influence on the inheritance of resistance. Resistance genes in Reichenbachii were recessive; therefore, breeders should consider the use of relatively large F₂ populations to effectively transfer these genes to cultivars with good agronomic characteristics.
