Presence of vibrios and aeromonas strains and total psychrotrophs in hegagonal spotted grouper and Spanish mackerel fish

This work was conducted on different parts of hexagonal-spotted grouper and Spanish mackerel fish from 10 major fishery shops in Riyadh City to assess the presence of vibrios and aeromonas using the AP120E and Biolog system. Also, pH and total psychrotrophs were assessed as two indexes of quality. Similar data were obtained from both identification systems except for Aeromonas media-like and vibrio anguillarum which are not included in the AP120E database.Aeromonas hydrophila, A. media-like, V. alginolyticus, V. anguillarum, V. damsel and V.fluvialis were recovered from fish samples with A. media-like and V. damsel most predominant. Unexpectedly, V. cholera and V. parahemolyticus were not recovered. The number of skin samples of grouper having more than 7 log CFU/gm were much higher than that of mackerel skin samples. Similar psychrotrophic counts were noticed in gut samples of the two fish types, indicating similarity in growth habitat. Most of the grouper flesh samples had a pH in the range of >6.40-7.02, whereas 95% of mackerel samples had a pH at 6.40 or below

Microbial and Sensory Quality of Fresh Camel Meat Treated with Organic Acid Salts and/or Bifidobacteria

Fresh camel meat samples were treated by dipping in solutions of sodium acetate (10% w/w), potassium sorbate (1.5%w/w), sodium lactate (5% v/v of 60% solution), or trisodium citrate (1.5% w/w), alone or combined with Bifidobacterium breve cell suspension (5%) and stored at 4ºC. The pH, psychrotrophs, and sensory attributes were evaluated. Sodium acetate alone or combined with Bifidobacterium breve cell suspension (5%) and stored at 4ºC. The pH, psychrotrophs, and sensory attributes were evaluated. Sodium acetate alone or combined with bifidobacteria maintained pH level, extended microbial shelf life (>12 days) and minimized surface discoloration. Bifidobacteria cell suspension when applied alone had negligible effects on microbial and sensory attributes. However, when combined with sodium acetate or potassium sorbate, bifidobacteria exhibited an additive effect on suppressing spoilage microorganisms

Bariatric Surgery as Treatment Strategy of Obesity in Saudi People: Effects of Gut Microbiota

Obesity prevalence is rising globally, as are the number of chronic disorders connected with obesity, such as diabetes, non-alcoholic fatty liver disease, dyslipidemia, and hypertension. Bariatric surgery is also becoming more common, and it remains the most effective and long-term treatment for obesity. This study will assess the influence of Laparoscopic Sleeve Gastrectomy (LSG) on gut microbiota in people with obesity before and after surgery. The findings shed new light on the changes in gut microbiota in Saudi people with obesity following LSG. In conclusion, LSG may improve the metabolic profile, resulting in decreased fat mass and increased lean mass, as well as improving the microbial composition balance in the gastrointestinal tract, but this is still not equivalent to normal weight microbiology. A range of factors, including patient characteristics, geographic dispersion, type of operation, technique, and nutritional and caloric restriction, could explain differences in abundance between studies. This information could point to a novel and, most likely, tailored strategy in obesity therapy, which could eventually be incorporated into health evaluations and monitoring in preventive health care or clinical medicine
