Infection of healthcare workers with methicillin resistant Staphylococcus aureus (HA-MRSA) occurs by direct contact with infected wounds, through hand contamination from asymptomatic people or medical devices. While Community-associated MRSA (CA-MRSA) infections arise in healthy non- hospitalized people or in those having medical procedure within the past year. The study was conducted from April 2021 to March 2022 to determine the rates of S. aureus and MRSA isolates, their antibiotic resistance and virulence factors among 712 specimens (308 out-patients and 404 healthcare workers) of Azadi and Bedari hospitals/ Duhok province. Staphylococcus aureus isolated at rates of 28.57% and 16.83%, among out-patients and healthcare workers, respectively. Male outpatients’, with ages of >40-50 years showed higher isolate rate than healthcare worker (46.15% vs 35.38% and 85.71% vs 25.36 %) respectively. CA-MRSA showed higher resistance to beta lactam antibiotics, while HA-MRSA showed higher multidrug resistance. Males of both MRSA types (CA-MRSA and HA-MRSA) carried higher isolate rates than females (38.46% and 15.87%) respectively. The higher rates of CA-MRSA and HC- MRSA isolates were 64.29% and 22.38% at ages of >40-50 years, respectively. PCR analysis detected nuc and mecA genes in 100% in both MRSA types. The distribution of virulence genes pvl, arcA and lukE- lukD among CA-MRSA of both hospitals were 41.03%, 28.02 % and 30.77%, respectively. While the distribution of these genes among HA-MRSA of both hospitals were 42%, 46.15% and 11.52%, respectively.

Methicillin-resistant Staphylococcus aureus (MRSA) is considered a serious public health problem. This study aimed to estimate the rate of MRSA among Staphylococcus aureus isolates of inpatients and to determine their susceptibility to antibiotics and some of the virulence genes. The study was conducted from April 2021 to March 2022 and involved specimens from 302 inpatients admitted to Azadi and Bedari teaching hospitals in Duhok province. Staphylococcus aureus was detected in 20.53% (62/302) of the examined specimens with the highest rate (37,50%) from surgical swabs. Antibiotics sensitivity tests showed that all isolates were resistant to penicillin G. Methicillin-resistant S. aureus was detected in 77.42% (48/62) of S. aureus isolates with a higher rate from skin swabs (85.71%). According to gender, a significantly (P<=0.005) higher rate of S. aureus and MRSA isolates was recorded in Males (21.52%). As regards age, ages > 40-50 years showed the highest rate of MRSA isolate (24.62%). Among MRSA, 77.08% (37/48) were multidrug resistant. Molecular analysis revealed the presence of nuc, mecA, pvl and eta genes at rates of 100%, 66.6%, 31.2% and 22.9%, respectively among the analyzed isolates.

Otitis media define as infection of middle ear that causes inflammation (swelling and redness) and fluid build-upbehind the eardrum.Anyone can develop an infection of the middle ear. It is eitheracute orchronic in two forms, the chronic maybe associated with effusion (intact tympanic membrane, eardrum perforation) which is an inflammation of the middle earmucosa and mastoid air cells for more than 3 months. This inflammation is either a sequel to acute suppuratve otitis media (tubotympanic disease) or can be caused by cholesteatoma .In the acute otitis media, which is always associated with ear pain andsometimes associated with effusion. Analysis of acute otitis infection by diagnosis of the highest bacterial species in the sampleof swabs from university ear students. In the biology department, we took 298 patients, including students at different stages.First, the student asked whether he had ear pain, effusion, or past doctor or hospital visits to treat this infection. Samples arecollected from the infected ear and then sent to the laboratory for bacteria analysis, bacteriological study and biochemical testsperformed to determinestaphylococcus aureus resistance to methicillin andPseudomonas aeruginosa (MDR). Staphylococcusaureus biochemical test such as: mannitol fermentation, gram stain, positive catalase and essentially negative oxidase, coagulateall positive. On the other hand, all biochemical tests including: pigment production at nutrient agar and positive catalase, Simoncitrate positive, forpseudomonas aeruginosa. In our cases of acute otitis media,Pseudomonas aeruginosa considered the oneof the most common microorganism, followed byStaphylococcus aureus, methicillin resistance. Pseudomonas aeruginosatrend showed resistance of about 5 case of students resistance to these antibiotics to specific drugs called ciprofloxacin, but theother antibiotics were sensitive, such as amikacin, ceftazidime, gentamycin, etc.Conclusion : 1.The most prevalent pathogen wasPseudomonas aeruginosa followed by isolatedStaphylococcus aureus fromear of students.2. Ciprofloxacillin has been found to be the most appropriate antibiotic despite some cases of students havingresistance to this drug, but the highest cases ofPseudomonas aeruginosaare sensitive to the same drugs followed by amikacinand ceftazidime (PDF) INFECTION WITH ACUTE OTITIS MEDIA CAUSED BY PSEUDOMONAS AERUGINOSA (MDR) AND STAPHYLOCOCCUS AUREUS (MRSA).

Background: Foodborne illness are caused by the consumption of food that is contaminated with either bacteria or their toxins and the most common causes are psychotropic bacteria which cause major public health problem. The aim was to detect and enumerate pathogenic bacteria in locally made ice cream. Methods: 250 locally made ice cream samples were randomly collected from automatic soft machines and dipping cabinets in the markets of Zakho city over a period of ten months starting in July 2016 to May 2017. All collected samples were transported to the microbiology laboratory. The most probable number methods used for detection and enumeration of pathogenic psychotropic bacteria. Results: In general, both types of ice cream samples were showed heavy contamination with aerobic bacteria. The Staphylococcus aureus (MRSA) counts exceeded the standard limits in all samples; the count in dipping cabinets' samples was higher than automatic soft machines samples whereas Coliform count in automatic soft machines samples was higher than dipping cabinets' samples. High incidence of Salmonella and Listeria monocytogenes had been detected in all ice cream samples and the range in samples from automatic soft machines were higher than samples obtained from dipping cabinets.

This research was conducted to recovery and enumerates the Froze injured bacteria isolated from different brands of ice cream sold in Zakho–Duhok markets. A total of 100 samples of ice creams with different flavors (plain, Mix chocolate and Mix fruit) were analyzed. All samples showed aerobic mesophilic bacteria count within the standard. The injured Coliforms bacteria were recovered and the count was exceeded the limits in four brands (Chyaw, Amca, Twin and Mufid) while no coliforms bacteria had been detected in other brands (Adlin, PAK and Bernard) which indicate post-treatment contamination from water, and unpasteurized milk. All brand ice cream show recovery of injured Staphylococcus aureus ranged from (10 MPN/g) to (220 MPN/g). The results indicate that the highest contamination was found in Mix chocolate of PAK brand (220 MPN/g), Mix chocolate of Domino brand (210 MPN/g), Mix fruit and Mix chocolate of Mufid brand (201 MPN/g and 200 MPN/g), which indicate the contamination of flavorings and ingredients during production. None of the samples from Adlin, PAK and Bernard brands showed the presence of injured Salmonella spp. while in contrast of Chyaw, Amca, Twin and Mufid brands which showed heavy contamination ranged from (7 MPN/g) to (250 MPN/g), the highest contamination was found in all types of Twin and Mufid brands followed by Amca brand, which indicate post process contamination or contaminated the tank with raw milk. Results show ice cream is unsuitable for consumed and the need of observing the hygienic quality of markets. The presence of injured pathogenic bacteria in commonly

The treatment of methicillin resistant Staphylococcus aureus (MRSA) infection is challenging because of their high resistance to different antibiotics. The objectives of this study were to determine the prevalence of S. aureus and MRSA nasal carriers among healthy students in Zakho University and to study their resistance pattern to vancomycin. During December 2013 to July 2014, a total of 405 nasal swabs were collected from healthy students and screened for S. aureus. The microorganisms were identified based on morphology and biochemical tests. Then, antibiotic susceptibility to methicillin and vancomycin was determined. The nasal carriage rate of S. aureus and MRSA among participated students were 17.5%(71/405) and 4.2%(17/405), respectively. The highest nasal carriage rate of S. aureus was found in third year students (24.7%, p= 0.04). The nasal carriage rate of S. aureus was more common in males than females (20.6% and 14.8%, respectively, p= 0.14). However, the nasal carriage rate of MRSA was more common in females than males (5% and 3% respectively, p= 0.45). All isolates were sensitive to vancomycin. S. aureus and MRSA nasal carriage rates observed amongst university students were comparable to other studies. The transmission of S. aureus and MRSA colonization, infection, and treatment should be explained to the students in order to prevent the spread and control their infections.
