In order to assess the immunopathological effects of aqueous Echinacea purpurea extract (EPE) on mice experimentally challenged with Pasteurella multocida serotype A, forty female BALB/c mice were randomly divided into four groups. The groups included a control group (received sterile distilled water 2 times/week for 2 weeks, intraperitoneally and then 100 μl sterile saline intranasally), a PMA...

Background & Aim:Nowadays, the use of chemical preservatives has been limited due to the controversial adverse effects. In this study, we evaluated the preservative potency of product with active herbal ingredients (Barij Baby cream) in contrast with the same products with two different chemical preservatives including methylparaben plus propylparaben and potassium sorbate plus...

A comparison of two types of scalders was conducted to determine their effectiveness in reducing bacterial contamination of poultry carcasses. A conventional hot-water scalder and a prototype model of a steam scalder were tested under commercial conditions. Total plate counts from steam-scalded birds were significantly lower than the counts of water-scalded birds immediately after scalding and ...

Post-harvest changes in the quality of cut and whole S. latissima upon 23 days storage with or without acidification at different temperatures were studied by bacterial counts, amino acids composition, 1H-NMR profiling extracted metabolites. Lowering temperature inhibited growth, seaweed stored 10 4°C had same counts as 2 room temperature. Cutting reduced degradation mannitol, free acids, other...

The discovery of communication systems regulating bacterial virulence has afforded a novel opportunity to control infectious bacteria without interfering with growth. In this paper we describe the effect of subinhibitory concentrations of phenyllactic acid (PLA) on the pathogenicity of Pseudomonas aeruginosa in mice. The animals were inoculated by oral (p.o.), intranasal (i.n.), intravenous (i....

Very little is known of the microflora in tortillas, the major component in the diet of many Guatemalans and other Central Americans. Based in a Guatemalan highland Indian village, this study examined the types and amounts of bacteria, yeasts, and molds in tortillas and in their maize precursors. Coliforms, Bacillus cereus, two species of Staphylococcus, and many types of yeast were the main co...

BACKGROUND Bacterial contamination of colostrum is common and can decrease IgG absorption in neonatal calves. Strategies that mitigate this situation without complicating colostrum management will benefit dairy calf health and survival. OBJECTIVES To evaluate the effects of supplementing colostrum with oligosaccharides (OS) on serum IgG concentration and apparent efficiency of absorption of I...

In 6 patients with bacterial endocarditis studies were made of the bacterial content of arterial and venous blood. Paired samples were collected, approximately simultaneously, from two different locations in the circulatory system, and colony counts were determined. As many as 48 specimens were taken for culture during a single period of study. Venous blood was drawn not only from different loc...

The dairy farmer has the responsibility of producing milk under clean and hygienic conditions, employing appropriate techniques to clean and disinfect the milking equipment and the milking parlour. The ability of raw milk to retain its quality under storage, and the safety of the product for the consumer, can both be directly related to the bacterial content of the milk. In most countries, bact...

The results of cultures carried out on urine collected by a midstream technique (MSU) have been compared with the results of cultures of urine collected by suprapubic bladder aspiration (SPA) in the same 903 patients. Comparisons indicate that when there are more than 100 x 10(6)/l (100 000/ml) Gram-negative bacteria in the midstream urine this finding is confirmed by suprapubic aspiration in 9...
