Caprine strains of staphylococci show strong and early results in carbohydrate fermentation tests. Their ability to produce DNase and acetoin is weak but they possess a reasonably high degree of phosphatase activity. All the 82 isolates of Staphylococcus aureus isolated from clinically healthy and sick goats produced acid from D-(+)-glucose aerobically at 37 degrees C within 24 h, 98.8% fermented both D-mannitol and maltose, 98.7% fermented sucrose, and 81.7% fermented D-(+)-xylose with acid production, but none fermented L-sorbose. Of the ten coagulase-negative staphylococci characterized to be of animal origin, three produced DNase, but none fermented dulcitol and L-sorbose. All fermented D-(+)-glucose, maltose and D-mannitol, eight fermented D-(+)-xylose and D-sorbitol with acid production. Whilst other coagulase-positive and coagulase-negative staphylococci showed different antibiotic susceptibility patterns, the ten coagulase-negative staphylococci characterized to be of animal origin showed similar antibiotic susceptibility patterns. 相似文献

Aadun and kokoro were produced from maize grains by processes involving roasting, kneading, spicing, and frying. Aadun with a moisture content (MC) of 12.5%, pH 5.3 had the following composition: crude protein, 7.49%; fat, 28.5%; total carbohydrate, 60.0%; ash, 3.0% and energy value, 3,600 kcal/kg whilst kokoro with a MC of 16% and pH 5.1 had, respectively: 6.42%; 22.9%; 66.6%; 2.84% and 3,550 kcal/kg. Whilst aadun and kokoro stored under ambient conditions (28±2°C; 75–80% RH) became mouldy within 7 days, samples treated with 1% butyl paraben did not develop off-colour and mouldiness. 相似文献

Abstract Village weaverbirds (Ploceus cucullatus Muller) normally feed on early maize in the morning (0800 to 1100 h) and evening (1600 to 1800 h) in southwestern Nigeria. However, when disturbed the birds feed during all the hours of daylight, and to be effective bird scaring would have to persist throughout the day. Developing grains are eaten, but rarely dry grains. The period of active bird scaring can therefore be reduced to about two weeks. In 1977 the mean percentage damage varied from 2.2 ± 0.3% in plots with dry ears to 34.1 ± 12.7% in plots with fresh ears, but in 1978 the situation was reversed with 17.7 ± 3.1% damage in plots with dry ears to 1.1 ± 0.2% in plots with fresh ears. The pattern of damage to early maize is associated with the annual rainfall, which determines the occurrence of lepidopterous larvae and wild sorghum (Sorghum arundicearum Stapf) which form alternative food items for the birds. Less than 2% of late maize ears was damaged since alternative food resources were abundant. Only early maize may need protecting from bird damage, but there was no definite relationship between time of planting and amount of damage caused. 相似文献

In the maintenance of shelf-stability, nutritional and organoleptic properties of ground melon egusi—Colcynthis eitrullus L., vacuum-packaged samples were found to be better than unpackaged samples and samples treated with 0.2% butylated hydroxyanisole (BHA) and 0.02% BHA + 0.045% sodium metabisulphite. After 56 days at 35°C, stored samples showed significant differences (P 0.01) in chemical composition peroxide value (PV), fungal counts and organoleptic attributes. Lipid oxidation and, to a lesser extent, fungal deterioration were responsible for the spoilage of stored ground melon kernel. The dominant fungal flora isolated from stored samples were of the generaPenicillium, Botryodiplodia, Rhizopus andAspergillus. 相似文献

Samples of sundried, matured red pepper,Capsicum annum with a moisture content (MC) of 12.7–26.8 percent had on dry weight basis, vitamin C, 5.0–6.4 mg/100 g; crude protein, 0.8–1.2 percent; total soluble solids, 3.3–4.1 percent, and fungal counts of log 4.4–4.5/g. Ordinary matured redC. annum had MC, 75.7–78.2 percent vitamin C, 36.1–38.5 mg/100 g; crude protein, 2.4–2.8 percent; total soluble solids, 9.3–9.9 percent and fungal count of log 3.32–3.39/g. Sundried matured redC. frutescens had corresponding values of 9.4–18.7 percent; 5.8–6.3 mg/100 g; 0.8–1.1 percent; 0.9–2.6 percent and log 3.2–3.4/g. No aflatoxins were detected in sundried, matured redC. frutescens, but aflatoxin B1 values obtained fromC. annum varied from non-detectable to 2.2 µg/kg. Dominant fungi isolated fromC. annum andC. frutescens wereRhizopus oryzaze,Aspergillus niger,A. flavus,Geotrichum candidum andSaccharomyces spp. 相似文献

During the production of tuwo from laboratory-contaminated corn (AFB1:150 mcg/kg) and sorghum (AFB1:87.5 mcg/kg) grains, reductions in the aflatoxin-B1 levels of pastes boiled for 30 min and 60 min were found to be 68.0% and 80.8%, respectively. In the preparation of ogi from contaminated corn and sorghum grains, reductions of about 72.5% and 71.4%, respectively, were obtained after fermentation at ambient conditions. Reconstitution of ogi paste into a porridge (akamu) considerably reduced the AFB level. 相似文献

Summary Relationships that exist among grain yielding ability and response and stability of grain yields when tested over variable environments were examined. Two sets of oats lines were tested over many environments that had wide ranges in productivities. The lines in each set were divided into high-, medium-, and low-yielding groups on the basis of means across all environments, and variance components for genotype × environment interactions and means of regression responses and coefficients of determination were computed for the three yield categories in each set.Mean grain yields for the high-, medium-, and low-yielding groups across both sets of oats lines were 2.7, 2.3, and 1.9 Mg ha-1, respectively. Coefficients of variability for the genotype × environment interaction were 18%, 16%, and 12% for the high-, medium-, and low-yielding categories, respectively. Means for regression responses were 1.22 for the high group, 0.99 for the medium, and 0.78 for the low. Most responses for the high and low groups were significantly different from 1.0. Means for coefficients of contingency were 0.63, 0.56, and 0.51 for the high-, medium-, and lowyielding groups, respectively.There was a positive relationship between mean grain yield and response of grain yield to improving environments. Thus, high yielding lines are also the responsive lines. Our study gave conflicting results about stability of production for the three yield groups. Coefficients of variation for genotype × environment interaction indicated that the high-yielding group was more interactive with environments than were the medium- and low-yielding ones: However, the means for coefficients of contingency indicated that the high yielding group was the most stable.Journal Paper No. J-12128 of the Iowa Agric. and Home Econ.

Summary The bacterial and parasitic infections associated with field cases of bovine fascioliasis due toFasciola gigantica were investigated; 47.6% of infected cattle had blood parasites, 61.9% had faecal-borne parasites and 85.8% had positive bacterial isolates in the bile in contrast to 13.3% with blood parasites, 71.1% with faecal-borne parasites and 28.9% positive for bile bacteria among uninfected cattle.
Trypanosoma spp.,Babesia, Paramphistomum andSchistosoma were the most commonly found parasites associated with fascioliasis. On the other handStaphylococcus pyogenes, Escherichia coli and mixed infections of these with otherEnterobacteriaceae were the common bacteria isolated from the bile of infected cattle. The parasitaemia ofBabesia was significantly higher in infected than uninfected cattle but there was no significant difference in strongyle egg count between the 2 groups of cattle.
Fascioliasis Bovina En Nigeria-Infecciones Intercurrentes Parasitarias Y Bacteriales
Resumen Se estudiaron las infecciones intercurrentes tanto parasitarias como bacteriales en casos naturales deFasciola gigantica; el 47.6% del ganado infectado tenía hemoparásitos, 61.9% tenía parásitos derivados de las heces fecales y en el 85.8% se hicieron aislamientos bacteriales positivos de la bilis. Esto en contraposición a 13.3% de hemoparásitos, 71.1% con parásitos derivados de las heces fecales y 28.9% aislamientos bacteriales positivos hechos de la bilis de ganado no infectado conF. gigantica.Los parásitos más comunmente asociados con fascioliasis fueronTrypanosoma spp.,Babesia, Paramphistomum y Schistosoma. Las bacterias aisladas de la bilis de ganado con fascioliasis fueron:Staphylococcus pyogenes, Escherichia coli, existiendo ambas también en forma mixta y asociadas con otras Enterobacteriaceas. La parasitemia conbabesia fue la más importante en ganado con fascioliasis. No hubo diferencia en los dos grupos de ganado (infectados y no infectados) en cuanto al conteo de huevos de especies de estrongilos.
La Fasciolose Bovine Au Nigeria. Parasitisme Intercurrent Et Infections Bacteriennes
Résumé Les infections parasitaires et microbiennes associées à la fasciolose bovine naturelle due àFasciola gigantica ont été étudiées; 47,6 p. 100 des animaux infectés étaient porteurs de parasites sanguins, 61,9 p. 100 avaient des parasites fécaux et 85,8 p. 100 avaient des bactéries dans la bile contre respectivement 13,3 p. 100, 71,1 p. 100 et 28.9 p. 100 chez le bétail indemne de fasciolose. Trypanosoma spp.,Babesia, Paramphistomum etSchistosoma ont été les parasites les plus souvent associés avec la fasciolose. D'un autre côté,Staphylococcus pyogenes, Escherichia coli et des infections associées de ces derniers avec d'autres entérobactériacées ont été les bactéries les plus communément isolées de la bile ds animaux parasités. La parasitémie parBabesia a été significativement plus élevée chez le bétail infecté que chez le bétail sain, mais il n'y a eu aucune différence significative dans le nombre des oeufs de strongylidés entre les deux groups d'animaux.相似文献

Of 136 strains of coagulase-negative staphylococci isolated from healthy and sick human beings, goats, sheep, antelope and other animals, 88 (64.7%) were Staphylococcus sciuri and 35 (25.7%) were S. lentus and the remainder Staphylococcus gallinarum. The strains of S. sciuri were isolated from humans with boils and wounds, goats with pestes des petits ruminants (PPR) and dogs with nasal discharge. One isolate of S. gallinarum came from a fowl with chronic respiratory disease and 11 others were isolated from goats. The characteristics of S. sciuri, S. lentus and S. gallinarum isolated from different sources were similar. 相似文献
