APPLICATION OF STOOL ANTIGEN TEST FOR MONITORING HELICOBACTER PYLORI AMONG HUMAN IN ERBIL GOVERNORATE, KURDISTAN REGION/IRAQ

Objective: This work was connected to screen Helicobacter pylori among human in Erbil Governorate by using stool antigen test (SAT).Methods: In a clean and sterile container, three hundred stool samples were collected from both sexes during the period from July-December 2017. Samples were collected from 150 males at the rural and an urban area in equal number, similarly 150 females same areas. The collected samples were tested in Microbiology Laboratory, Department of Pathological Analysis using One-Step H. pylori Antigen Test Kit.Results: The obtained results shown that the prevalence of H. pylori in total samples were (11.3%). The rate of infection among females were (12.7%) compared to (10.0%) of male infection rate. According to the age wise of the patients (11-20, 51-60 and above 60 y) results showed that the H. pylori antigen rates were (16.3%, 11.9%, and 13.6%) respectively that mean the high rate of infection was varied. According to habitation, the high rate of H. pylori among males was 12.0% and 8.0% in rural and urban area consecutively. While the occurrence rate of H. pylori antigen among female was high 14.7% in rural area, compared to 10.7% in the female of the urban area. The proportion of H. pylori antigen rate in September, December and October were (16.0%, 14.0%, and 12.0%) respectively.Conclusion: From this study, we concluded that the prevalence of H. pylori among human in Erbil Governorate was high, and the infection takes place in the early years of life. The significance of public health risks was discussed

Meat Borne Diseases

Red and white meat is a perfect, high-quality protein that comprises all of the nine essential amino acids (EAAs) that cannot be synthesized endogenously. Meat is the normal source of this vitamin, as well as other types of vitamins. Meat affords a range of significant vitamins and minerals that the human body needs, many of which are more bioavailable and easily absorbed than the nutrients found in plant sources. The nutrients in meat support the immune system, participate in the formation of muscle tissue, red blood cells (RBCs), and hormones, and warranty accurate functioning of the nervous system. These nutrients also affect the human senses of smell and taste, benefit our thyroids, and support antioxidant production. The main sources of pathogens in meat and meat products are; the animal itself; human handlers; equipment’s in contact, environmental sources, and water used in the preparation. Meat Borne Diseases, since ancient times, played a central role in public health. This chapter is divided into nine parts, part one to part eight deals with the most important pathogens that have been associated with meat borne diseases (MBDs), these include, Meat Borne Prionic Diseases; Viral Diseases; Bacterial Diseases; Protozoal Diseases; Parasitic Diseases; Fungal Diseases; Mycotoxins; Rickettsial Diseases; while the nine-part deal with the methods of meat preservation and storage

Isolation, Serotyping, and Antibiogram of Salmonella Isolates from Raw Milk Sold at Retail Vending in Erbil City, Iraq

Pathogenic strains of Salmonella cause gastroenteritis in humans globally.This study aimed to determine the prevalence and antibiotic susceptibility pattern of Salmonellain raw milk sold in Erbil city, Kurdistanregion, Iraq. A total of 470 samples were collected from retail vendors between January and June 2019. Samples were cultured on selective media followed by serotyping and antibiotic sensitivity testing by disk diffusion assay.The results revealed that the overall prevalence of Salmonella was 7.9%. The isolates belonged to nine (9) different serotypes: S.Typhimurium 18.9%, S.Anatum 10.8%, S.Muenchen 13.6%, S.Enteritidis 10.8%, S.Senftenberg 8.1%, S. Newport 10.8%, S. Arizona 10.8%, S. Montevideo 8.1%, and S.Dublin 8.1%. The antibiotic resistance profile revealed that 67.6%, 62.2%, 56.8%,and 56.8% of isolates were resistant to levofloxacin, streptomycin, imipenem, and tetracycline respectively. This resistance among Salmonella maypose a public health threat that needs activesafety measures and response

Frequency and seasonality of viable <i>Helicobacter pylori</i> in drinking water in Dhamar Governorate, Yemen

Helicobacter pylori is an important and common bacterial pathogen in humans. The accumulated evidence of H. pylori's existence in water from different environmental sources suggests a water-borne transmission route. This study aimed at investigating the occurrence of H. pylori in different water sources used by human populations in Dhamar Governorate, Yemen. 250 samples were randomly collected from the municipal water supply network, wells, and springs. The samples were processed, plated onto modified campy-blood agar, and incubated under microaerobic conditions for 4-10 days. Bacterial identification was based on morphological properties and biochemical tests. Bacteriological analysis showed that 9.6% and 13.2% of tap and surface water samples were contaminated with H. pylori, respectively. Despite a higher frequency in samples from rural areas, these were not significantly (p=0.068) more contaminated than the samples from urban areas. Regarding the seasonal variations of H. pylori detection, 85.71% of positive samples were detected in the late winter and spring seasons (February to May). To conclude, H. pylori transmission through water is likely to occur in Dhamar Governorate. Further prospective studies are highly recommended to provide further evidence and a clearer picture of H. pylori transmission

Validity of cold storage and heat treatment on the deactivation of <i>Vibrio parahaemolyticus</i> isolated from fish meat market

Vibrio parahaemolyticus is a zoonotic disease transmitted to humans when handling or consuming improperly cooked fish meat. This study aimed to evaluate the effect of thermal treatment on V. parahaemolyticus isolates. Different heat treatment methods are used to determine the best methods for controlling V. parahaemolyticus, isolated from fish meat, which include microwave, low-temperature long time, and high-temperature short time methods. The V. parahaemolyticus isolates significantly declined in bacteria count when they were kept at 4°C, and 25°C for a long time, and the V. parahaemolyticus isolates significantly declined in bacteria count manner when they were kept at -20°C for a long time. The high temperature and long-time exposure at 75°C/25 minutes by moist heat, 87°C/5 minutes by dry heat, and 70°C/20 minutes by frying heat were enough to kill V. parahaemolyticus isolates. This work can be useful to decrease the hazards of infections related to V. parahaemolyticus and reduce the causes of fish-borne pathogens

Milk-Borne Diseases

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
