A total 270 samples, 30 each minced beef, meatball, beef burger, chicken nuggets, pane, canned anchovy, mackerel, and sardine, were obtained from supermarkets in Aswan Province, Egypt, analyze occurrence virulence features hydrophila. Influence Citrus reticulata...

Meat is among the most popular foods because of its high dietary component. However, it contaminated with various food spoilage bacteria, including Pseudomonas aeruginosa, identified as a primary contributor to and foodborne illnesses. This investigation evaluates total aerobic psychrotrophic counts, anti-bacterial resistance, virulence features in P. aeruginosa bacteria discovered 150 beef products. Thirty each basterma, hot dogs, luncheon, frankfort, burgers were obtained from numerous...

One of the most commonly occurring foodborne, tissue cyst-forming protozoan zoonotic parasites with public health and veterinary relevance is Sarcocystis species. This research was conducted using traditional molecular techniques to identify incidence spp. in 750 slaughtered bovine animals varying age sex (375 cattle 375 buffalo) at various abattoirs Aswan Governorate, Egypt. The overall occurrence macroscopic lesions buffaloes 20.5% 38.4%, respectively, while microscopic infection 30.4%...

To investigate the use of a light scattering sensor, BActerial Rapid Detection using Optical Technology (BARDOT) coupled with multipathogen selective medium, Salmonella, Escherichia and Listeria (SEL), for concurrent detection three major foodborne pathogens in single assay.BARDOT was used to detect distinguish pathogens, Salmonella enterica, Shiga toxin-producing coli (STEC) monocytogenes from food based on colony scatter signature patterns SEL agar (SELA). Multiple strains test were grown...

Bovine cysticercosis is categorized as a serious parasitic zoonotic infestation. The infection mainly caused by the tapeworm Taenia saginata, which infects cattle and humans. larval stage, Cysticercus bovis (C. bovis), found in skeletal cardiac muscles of infected cattle. Despite its potential public health concern, few studies have been conducted on Upper Egypt. This study investigates prevalence, epidemiology, impact Egypt, emphasizing how histopathological changes muscle physiological...

Tenderness is an important sensory attribute to the overall eating experience of beef. Identifying novel methods ensure consistent tenderness, especially in inherently tough cuts, critical for industry. This study investigated if tumbling without brine inclusion could be effective method improve quality and palatability attributes beef longissimus lumborum (LL) semitendinosus (ST) steaks. Furthermore, interactions with postmortem aging were evaluated determine how might affect protein...

Many microbiology classes include a bacterial unknown identification project (BUIP), in which students identify an microorganism. The COVID-19 pandemic forced change instructional methods from in-person to online version of this project. Our aim was determine how the shift learning person impacted three aspects student engagement: satisfaction, as measured by withdrawal rate course; enthusiasm, evaluated self-efficacy; and learning, determined using non-point-based questions. To address...

Abstract Parasites pose significant challenges to aquaculture and fisheries industries. Our study focuses on the Polyonchobothrium magnum African catfish address a potential health issue in aquaculture, explore host–parasite interactions that can help develop effective management practices ensure fish industry sustainability. P. was isolated from stomach of ( Clarias gariepinus ) as primary site infection, with prevalence 10%. Most affected were heavily infected (8 out 10). Infection...

A total of 600 cattle (200 from each New Valley, Qena, and Aswan) were verified by a single intradermal cervical tuberculin test (SICTT), the positive reactors slaughtered at central abattoirs governorate. Additionally, tissues affected carcasses inspected Ziehl-Neelsen (ZN) staining culturing, confirmation results was achieved through ELISA PCR techniques. The findings revealed that 2.3% animals tested for SICTT test. Qena recorded highest rate tuberculin-positive 3.5%, followed Aswan 2%...

The microbial analysis of fish is critical for ensuring overall health. Uncooked can serve as a conduit transmitting several types microbes; the current investigation sought to assess bacterial levels in various kinds from Nasser Lake, Aswan, Egypt, considered chief source potable water Egypt. Two hundred and fifty samples, including 50 each Oreochromis niloticus , Sander lucioperca Lates Clarias gariepinus Mormyrus kannume were collected detect load, isolation, identification Aeromonas...

Background: Fish is considered an important food because it includes main nutrients (proteins, fats, and ash) micronutrients (vitamins minerals). The assessment of fish nutritional content data may offer crucial recommendations regarding freshwater consumption preserving human well-being. Aim: Evaluate the safety quality properties Nasser Lake fish, Aswan, Egypt. Methods: A total 250 samples, 50 each Nile tilapia, perch, Zander, Catfish, Elephant-snout, from Lake, Egypt; beheaded,...

Bovine tuberculosis (BTB) still represents a significant public health concern and economic issue for livestock breeders in Egypt. This research investigates the incidence of bovine cattle slaughtered at central abattoir Aswan, Egypt, 2023. A total 720 were checked antemortem postmortem abattoir. The suspected lesions analyzed with acid-fast staining, microscopy, histology, ELISA, RT-PCR. Based on gross tubercle lesions, overall occurrence Aswan abattoirs was 3.2% (23/720), thoracic lymph...

Many introductory-level classes teach fundamental concepts, as they are prerequisites for upper-division courses. Therefore, the student body in these has diverse interests. To address this breadth of career trajectory, laboratory courses often include experiments that demonstrate a wide range microbiological techniques and processes. One is standard component many microbiology classes, Bacterial Unknown Identification Project (BUIP), limited to isolated organisms or specific environment....

This study assessed how fresh beef tumbling without brine inclusion combined with aging would affect quality, biochemical attributes, and descriptive sensory scores of sirloin muscles. Paired gluteus medius (GM), biceps femoris (BF), tensor fasciae latae (TFL) muscles from carcasses ( n = 16) at 5 days postmortem were assigned to 0 or 120 min tumbling, after which sections aged 10 days. Tumbled GM p < 0.001) TFL 0.01) had increased objective tenderness compared respective controls....
