“…A closely related result was obtained by Khoder et al [ 43 ] who recorded 41% of healthy asymptomatic residents in the United Arab Emirates as H. pylori positive. While higher detection rates were observed in the Egyptian patients stools by Salem et al [ 7 ] and Shaaban et al [ 44 ] at 73.7% and 74.8%, respectively, using the rapid antigen test, On the other hand, lower results were reported by Hassan et al [ 45 ], Almashhadany and Mayass [ 46 ], and Seid et al [ 47 ] as 25, 30.4, and 18.45%, respectively. This disparity in H. pylori prevalence could be attributed to the sociodemographic status of the investigated population, geographical variations, and hygienic measures.…”

“…Based on molecular detection, males were more infected (25, 48.08%) compared with females (6, 16.67%). Contrarily, a slightly higher infection rate was detected in females (19.55%) than in males (16.44%) by using an antigen screening test [ 46 ]. Through molecular and serological studies, which were done by Castro et al [ 52 ], Mehesin et al [ 42 ], and Shaaban et al [ 44 ], there was no significant higher infection rate in females than males, as 14.6, 11.2 and 55.5, 44.5 and 79.7, 65.5%, respectively.…”

Background Helicobacter pylori is a worldwide pathogen that affects both animals and humans with a wide environmental distribution, causing serious health problems in humans. This research has timely addressed the topic of new sources of H. pylori infection, which is currently a global issue, especially in developing countries. For this purpose, 115 Tilapia fish, 50 freshwater samples, and 88 fish-handlers’ stool samples were investigated for the presence of H. pylori in Qena Governorate, Egypt. The applied techniques were antigen screening tests, culturing, and molecular methods through ureC gene amplification, and 16 S rRNA characterization. Results Helicobacter pylori was detected in 7.83%, 14%, 4.35%, and 12% of the investigated fish and water samples by culture and PCR methods, respectively. Out of the total studied participants, 40 tested positive for H. pylori when screened by stool antigen test, of which 35 (39.77%), and 31 (35.23%) were confirmed by conventional and molecular techniques, respectively. The Fisher’s exact test has shown a statistically significant correlation between H. pylori infection, sex, and age as risk factors, while the association was insignificant concerning the residence. Males contracted the infection at a higher rate than females (48.08% and 16.67%, respectively). Also, H. pylori infection rate was the highest among fish-handlers aged 36–45 years old (46.67%), followed by the 26–35 years old age group (39.53%). With regard to the residence, a higher occurrence rate was recorded in the rural (36.07%) than the urban population (33.33%). Helicobacter pylori isolates harbored the highest antimicrobial resistance against ampicillin (100%), metronidazole (95.24%), while the least antimicrobial resistance was recorded against levofloxacin (21.43%), and clarithromycin (26.20%). The phylogenetic analysis revealed a high degree of homology between the isolates selected from Tilapia fish, freshwater, and fish-handlers. Conclusions Our data emphasized the role that fish and freshwater play in disseminating H. pylori infection as one of the diseases that has a significant public health issue.

“…pylori (HP) is among the most widespread human bacterial pathogens worldwide [26]. Numerous variables affect the prevalence of H. pylori infection, including socioeconomic status, geographic location, living conditions, and personal hygiene [27]. The main reservoir of H. pylori is infected individuals; however, the majority of these infections are asymptomatic [28].…”

Milk is a rich source of vitamins, minerals, and other vital nutrients. Potassium, B12, vitamin D, and calcium are nutrients that are lacking in many foods. Milk is also a rich source of magnesium, zinc, vitamin A, and thiamine (B1). In addition to lactose and fat, milk is an excellent source of protein and contains numerous fatty acids, including conjugated linoleic acid (CLA) and omega-3 fatty acids. The primary sources of pathogens in milk and dairy products are animals, human handlers, equipment in contact, environmental sources, and water used in preparation. However, milk borne diseases, since early time, played a principal role in public health. This chapter is divided into the following parts: mammary Glands, the phases of mammary gland secretion after birth, nutritive value of colostrum, nutritive value of milk, major sources of milk contamination, milk-borne diseases, techniques used in milk preservation, milk testing and quality control, prevention of milk-borne diseases, and conclusions.

“…Many epidemiological studies have identified particularly drinking water sources as a major risk factor for H.pylori infection [24][25]. The second of the two hypotheses instead proposes that H.pylori is spread directly from person to person, typically within the family or close communities [26][27].…”

Helicobacteriosis is a bacterial infection caused by Helicobacter pylori (H.pylori)(HP). which was discovered in 1982 by Australian scientists Barry Marshall and Robin Warren, who were later awarded the Nobel Prize in 2005.Epidemiological evidence has shown that H.pylori colonizes the upper gastrointestinal tract(GIT), and the infection is one of the most common human bacterial pathogens worldwide, with 4.4 billion infected individuals in 2015, but the prevalence varies according to situation and hygiene principles. Since this first isolation, it has become apparent that this organism may be one of the most common bacterial pathogens of humans, and it is one of the risk factors for adenocarcinoma. Thus, it was categorized as a group 1 carcinogen in 1994 by the World Health Organization (WHO). New infections with H.pylori are thought to occur as a consequence of direct human-to-human transmission, via either an oral-oral or fecal-oral route or both. H.pylori has been detected in stool, saliva, vomitus, and gastric refluxate, the material that has been subject to reflux, principally stomach acid that has leaked up into the esophagus. Clinically, H. pylori infection in humans is related to chronic gastritis, peptic ulceration, duodenal ulcer, and gastric cancer in addition to mucosa-associated lymphoid malignancies.According to the World Health Organization (WHO) estimates available at that time, it was supposed that about 4.4 billion infected individuals in 2015 were infected with H. pylori. These estimations can vary and are subject to change over time as recent investigations and information become obtainable. The prevalence of H. pylori is complex and affected by several factors, comprising age, clinical outcomes, geographical location, and socioeconomic status. A higher incidence was reported in unhygienic and economically poor areas; the rate of H. pylori infection in Africa, South America, and Asia was significantly higher than that in Western Europe, North America, and Australia. However, the disease spectrum of H. pylori infection shows a wide range of clinical aspects, including gastrointestinal diseases and extra gastric manifestations. In this review, we have described the general scope of these diseases.
