Efficacy of a new oxytetracycline aerosol against foot rot in sheep.

A test was designed to evaluate the efficacy of a new oxytetracycline aerosol in the treatment of foot rot in sheep. Of 186 sheep, 66 were treated with the test preparation, 61 were treated with an existing oxytetracycline aerosol and 50 acted as unmedicated controls. All affected feet in the three groups were first paired and then, for the two treatment groups, a single application of antibiotic aerosol was given. There was little difference in response between the two treated groups, but the improvement in both these groups was significantly greater than in the control group. The test was also applied to 60 cases of scald. One application of either the test product or its comparable antibiotic aerosol was effective in the treatment of scald.

Bovine digital dermatitis and severe virulent ovine foot rot: a common spirochaetal pathogenesis.

A potential pathological role for spirochaetes in bovine digital dermatitis (bovine DD) and severe virulent ovine foot rot (SVOFR) has been considered and a treponeme isolate obtained from each disease in the UK. In this work, we have investigated the hypothesis that the two diseases may have a shared (common) spirochaetal aetiology. Experiments were designed to identify serological similarities and differences between the two spirochaetes; an enzyme-linked immunosorbent assay (ELISA) was developed to detect anti-treponeme antibodies in the sera of cows and sheep against the two-treponeme isolates. Sera were further tested for antigen reactivity by Western blotting. Cattle and sheep with bovine DD and SVOFR, respectively, had increased seropositivity rates to both treponeme isolates, with different patterns of reactivity between farms. In some cattle herds, significant correlations were shown between antibodies to bovine DD treponemes and SVOFR treponemes (P<0.001). In other herds, there was no apparent cross reaction, suggesting the presence of more than one treponeme in bovine DD on some farms. There was no significant correlation between the two treponeme isolates when ELISA-tested against 58 sheep sera from SVOFR cases (P>0.05); sheep showed strong evidence of reactivity to one or the other treponeme antigens, but never to both. Western blotting against both treponeme antigens showed that they frequently displayed different antigen epitopes, although some minor bands were common to both organisms. The data suggest that there are a number of spirochaetes in UK farms, which could be involved in the pathogenesis of either bovine DD or SVOFR.

Organic amendments and control of foot rot of Piper betle caused by Phytophthora parasitica var. piperina.

Experiments have been performed to control foot rot of Piper betle by organic amendments and antagonists in soil. Soil amended with corn straw gave best control. Corn straw supplemented with nitrogen (NH4NO3) gave still better control. The effect of different antagonists growing on corn-straw and til (Sesamum indicum) oil cake amendments showed that Trichoderma viride gave best control. Aspergillus terreus failed to control the disease although it showed great antifungal activity under controlled condition in Petri dishes.

Susceptibilities of anaerobic bacteria isolated from animals with ovine foot rot to 28 antimicrobial agents.

The agar dilution method was used to determine the inhibitory activities of 28 antimicrobial agents against 35 strains of the genus Peptostreptococcus, 4 strains of the species Peptococcus niger, 20 strains of the species Megasphaera elsdenii, 7 strains from the species Acidaminococcus fermentans, 8 strains of the genus Clostridium, 11 strains of the genus Eubacterium, and 1 strain of the species Propionibacterium acidipropionici, all of which were isolated from 125 clinical cases of ovine foot rot between January 1987 and December 1988. The three unreidopenicillins studied proved to be the most active antimicrobial agents, with a high percentage of strains being susceptible at a concentration of 64 micrograms/ml. Penicillin G, ampicillin, and the three cephalosporins studied also had good activity. Fosfomycin showed a high degree of activity among the 116 anaerobic bacteria tested.

[Selection for disease and epidemic resistance in domestic ruminants and swine by indicator traits, marker and causal genes--a review. Part 2: Special immunogenetics of sheep and goats with particular regard for endoparasitoses, scrapie, foot rot and maedi-visna virus infection].

The introduction of the first part deals with immunogenetic investigations on the field of life-stock. The main chapter is outlined as a tabular overview of current opportunities of the application of indicator traits as well as marker and causal genes in breeding for disease resistance in cattle, sheep, goats and swine. In the discussion of the second part, emphasis was laied on diseases of small ruminants in central and western Europe with special respect of endoparasitoses, scrapie, foot-rot and maedi-visna virus infection. Indicator traits are discussed with respect of their advantages and disadvantages. The rigorous selection on specific traits is connected with an increase of the number of homozygotes. In contrary, pathogens do undergo mutations, thus escaping the host's immune system. Out of this point of view it is advisable, to set on selection very cautiously. The role of technologies of modern immunogenetics is pointed out in respect of constructing disease resistant animals.
