The study aimed to extract phenolic and flavonoid compounds from pomegranate seeds and banana peels by microwave technology, where the percentages of phenolic compounds in pomegranate seeds and banana peels were 40.60 and 32.27 mg GAE/g dry weight, respectively, while the flavonoid compounds were in pomegranate seeds and banana peels 2.48 and 17.8 mg catechins/g dry weight, and they were diagnosed using a High-performance liquid chromatography(HPLC) Technique device, and it was found that there is a number of phenolic compounds included (galic acid, caffeic acid, chlorogenic and ellagic acid), while flavonoid compounds included (catechins, quercetin, coumarin, and myricetin). and the inhibitory activity of the plant extracts was tested against a number of bacteria Escherichia coli (E.coli), Bacillus cereus(B.cereus), Staphylococcus aureus(S.aureus and Pseudomonas aeruginosa (P.aeruginosa), at three concentrations 3, 7and 10% which reached the highest inhibitory effectiveness of pomegranate seed extract and according to the order of its effect on bacteria as follows P.aeruginosa, E. coli, and finally B. cereus, as the diameter of the inhibition halo at a concentration of 10% reached 21 mm against P.aeruginosa bacteria, and pomegranate seed extract didn't show any inhibitory activity against S.aureus bacteria. Banana peel extract showed lower inhibitory efficacy than pomegranate seed extract, as the diameter of the inhibition halo against P.aeruginosa bacteria at a concentration of 10% to 11 mm, while the extract didn't show any inhibitory activity against B. cereus bacteria at any concentration. Pomegranate seed extract exceeded the highest concentration of phenolic substances in addition to containing a higher concentration of phenolic compounds and flavonoids diagnosed and had the highest inhibitory effectiveness against bacteria and molds.

This study was conducted at the College of Agricultural Engineering Sciences at the University of Baghdad. It lasted from November 15, 2022, until January 15, 2023. to determine the effect of replacing soybean meal with Azolla plant in the concentrated diet at a rate of 0%, 4%, 8%, and 12% on the properties of rumen fluid, the number of bacteria and protozoa, the coefficient of digestion of nutrients, and some blood properties for Awassi lambs. Twenty Awassi lambs were used, their weights ranged between 18 and 19 kg and their ages ranged from 3 to 4 months. They were housed in individual cages and fed a concentrated feed at 2.5% of body weight in the morning meal while roughage (barley straw) was provided freely.
The results showed that there were significant differences in the pH value of treatment T4 at the time of zero withdrawal of rumen fluid, as it was recorded at 7.74, while there were no significant differences between the treatments for the concentration of Ammonia Nitrogen (NH3-N) and Volatile Fatty Acids (VFA). The results showed a significant decrease (P≤0.05) in the numbers of bacteria and protozoa in the rumen fluid of the T2 treatment compared to the control treatment.

A field study was conducted at the College of Agricultural Engineering at the University of Baghdad to assess the susceptibility of maize varieties (Baghdad, Fajr and Maha) to the corn stem borer, Sesamia cretica. The results showed that the varieties differed in their susceptibility to the corn borer, with a significant difference between the Baghdad variety, which was the most susceptible variety, and the other varieties. The highest infestation rate was 30.49% on the Baghdad variety, and the lowest infestation rate was 9.84% on the Maha variety. The highest percentage of dead heart was 17.63% on the Baghdad variety, and the lowest percentage was 12.57% on the Maha variety. The results showed that the Baghdad variety had the highest percentage of loss in plant height 16.86% , number of larvae 2.90 larvae/plant, number of tunnels 5.86 tunnel/plant, tunnel length 15.79 cm/tunnel, and percentage of excavated area 11.01%. The lowest percentages were for the Maha variety, which were 10.5%, 1.57 larvae/plant, 3.81 tunnel/plant, 9.24 cm/tunnel, and 6.51%, respectively.

This study was conducted at the University of Baghdad, College of Agricultural Engineering Sciences, with the aim of extracting laccase enzyme from the bowels of termites. The concentration method was used by precipitation (with ammonium sulfate) with gradient saturation rates from 30% to 80%. The results showed that the highest effectiveness was at the saturation rate of 80%, reaching 5.991 units/mg, dialysis reaching 3.763 units/mg, and gel filtration reaching 7.644 units/mg. m and ion exchange amounted to 5.867 units/mg. The results of purification by gel filtration showed one distinct protein peak, and the ion exchange chromatography technique was used, as three protein peaks appeared, peak (1) representing the protein, and peak (2) representing the bound protein and it represents the laccase enzyme. After measuring the activity, one peak appeared, with an enzyme yield of 32.192. % and the number of purification times is 15,355.

The experiment was conducted in the Fish Laboratory for Postgraduate Studies at the University of Baghdad, College of Agricultural Engineering Sciences. A total of 140 fish were used and reared for 70 days. The fish were randomly distributed into seven experimental groups. These groups included the addition of dried Artemia to the second, third, and fourth groups at a rate of 50% of fishmeal powder. Fish internal organ powder was added to the third and fourth groups at rates of 25% and 50%, respectively, of fishmeal powder. Frozen Artemia was also added to the fifth, sixth, and seventh groups at a rate of 50% of fishmeal powder, and fish internal organ powder was added to the sixth and seventh groups at rates of 25% and 50%, respectively, of fishmeal powder. The results showed that Treatment T6 exhibited superiority in feed conversion efficiency, feed intake, feed conversion ratio, apparent digestibility coefficient of the diet, apparent digestibility coefficient of protein, protein intake, and fecal appearance time. This indicates better utilization of added food, especially frozen Artemia at 50%, and fish by-products (internal organs) at 25%. Therefore, it can be concluded that using frozen and dried Artemia at 50% and fish by-products (internal organs) at 25% can be a good alternative to imported fishmeal in the feeding of common carp, contributing to the improvement of the studied traits.

This study was conducted in the fish hatchery of Al-Suwayrah/ Department of Animal Resources/ Wasit/ Al-Suwayrah district, Iraq. 200 common carp fish with an initial average weight of 52 ± 0.00 grams per fish were fed on four experimental diets with two replicates each. The results showed that treatment T2 outperformed, followed by treatments T3 and T4, compared to the control treatment. The reason for the superiority of the second treatment may be attributed to the presence of a (33%) ratio of fish by-product powder, indicating the potential for replacing animal protein powder with fish by-product powder, along with 25% of stomach powder. This enhanced the nutritional value of the treatment, and the fish accepted the feed, which may be well-balanced in essential amino acids content. Based on the above-mentioned results, it is now possible to use stomach powder and fish by-products (internal organs) at a ratio of 33% as a partial substitute for animal protein in the diets of common carp fish in Iraq.

The aim of this study is to evaluate the anti-pyocyanin and anti-hemolytic efficacies of lactobacilli probiotics isolated from natural and commercial sources against pathogenic Pseudomonas aeruginosa (P. aeruginosa).
Two isolates of P. aeruginosa (P50 and P78), which were determined as multidrug-resistant bacterial strains, were obtained from one hundred-thirty samples, including burn, wound, ear, sputum, and urine, collected from patients attending a number of hospitals in Baghdad, including Al-Karkh Hospital, Al Kadimyia Teaching Hospital, and Medical City Hospitals (Al-shahid Ghazi Al-Hariri Hospital for Surgical Specialties, Baghdad Teaching Hospital and Burns Specialized hospital) during the period of October and December 2022. The direct antibacterial effect of undiluted CFCS (cell-free culture supernatants) of Lactobacillus isolates and their anti-pyocyanin and anti-hemolytic were assessed.
The antibacterial effect of a natural isolate of Lactobacillus acidophilus (L. acidophilus) was higher than that of other isolates. The findings revealed that spontaneously isolated lactobacilli outperform commercially isolated lactobacilli regarding probiotic characteristics. All Lactobacillus isolates showed a strong anti-hemolytic and anti-pyocyanin effects against P. aeruginosa at 100 µg/ml, but this effect is not confirmed due to their antimicrobial activity against both strains of P. aeruginosa. Also, both isolates of Lactobacillus plantarum (L. plantarum) (natural and commercial) did not show an anti-hemolysin effect against both isolates of P. aeruginosa P50 and P78.
The findings supported using probiotics instead of antibiotics to treat antibiotic-resistant pathogenic bacteria and, consequently, various disorders linked with this pathogenic bacterium.

This study was conducted to determine the validity of three species of frozen fish imported to Iraq. A comparison was made between the status of whole fish and fillets of the same species, and then a comparison was made among the three species of fish: seabream Sparus aurata, seabass Dicentrarchus labrax and tuna Tunnus alalunga, depending on some oxidation tests of frozen fish samples, included determination of free fatty acids (FFA) mg/100 mg fat, total volatile nitrogen (TVN) mg N_2 100g-1 meat, peroxide value (PV) meq Kg-1 meat, and thiobarbituric acid (TBA) mg MDA Kg-1 meat. The results recorded significant differences (P<0.05)) between the case of whole tuna and the fillet of thiobarbituric acid. The results showed that significant differences (P<0.01) were recorded in the total volatile nitrogen value of whole seprim fish and fillets, while tuna fish recorded significant differences (P<0.05)) between the state of whole fish and the fillets. The results recorded significant differences (P<0.01)) in the peroxide value between the state of whole fish and fillets for cyprim fish. The results showed, based on the examinations and comparison with the local and international specifications, that the meat of the fish under study, seabream, seabass and tuna imported to Iraq is considered suitable for human consumption.

A disturbance in the equilibrium of oral microbiota may represent a leading cause of poor oral hygiene. Dysbiosis of the microbiota is the main cause of inflammatory illnesses, known as periodontitis. Communication between Streptococcus spp. and other oral bacteria could be relevant, and therefore, indicators of different forms of periodontitis. The current study aimed to investigate the association between certain Streptococcus spp. with poor oral health and developing periodontal disorders. A total of 166 samples were collected from individuals attending Ghazi Al-Hariri Hospital for Surgical Specialties and Specialized Dental Centers in Baghdad, Iraq. S. mutans, S. sanguis, S. thoraltensis, S. infantarius, Aggregatibacter actinomycetemcomitans, Bifidobacterium spp. have been surveyed and identified in 166 individuals using VITEK 2 system. The results approved that the Streptococcus spp. colonisation have strong significant correlations with a certain periodontal disease alongside its relationship with other bacterial species. Mainly, infectious Streptococcus sanguis is significantly associated with gingivitis (rho = 0.239**, p= 0.002), but inversely corelated with acute periodontitis (rho= -0.165*, p= 0.034). Moreover, Streptococcus mutans is inversely associated with the chronic periodontitis (rho= -0.155*, p= 0.046) and significantly with dental caries & pulpitis (rho= 0.252**, p= 0.001). Streptococcus infantarius significantly correlates with chronic periodontitis (rho = -0.183*, p= 0.018) and inversely associated with the oral hygiene status. The findings indicate that streptococcal microbiota act as potential indicators for developing a range of periodontal diseases forms. However, the aggressive periodontitis was associated with Aggregatibacter actinomycetemcomitans. The findings suggest that further investigation of molecular oral microbiome is required to uncover their potency to develop the severity of oral diseases.

alpha-lactalbumin (α-Lac) is a crucial protein in several biological procedures like a strong antioxidant and prospective cancer therapy, This study was aimed to isolate, pacificate, and characterize α-lactalbumin α-Lac from Iraqi camel milk sourced from new local camel farms in Samawah Govermanate, southern Iraq. purified step done by ion exchange chromatography through DEAE-cellulose column and gel filtration chromatography through Sephadex G-100 column, the purification fold and yield were (58.20 time and 82%) respectively. The purity of α-Lac to homogeneity was examined by polyacrylamide gel electrophoresis under denaturing conditions (SDS-PAGE) with a single bond The molecular weight was determined by two methods and it was 14.40kDa and 14.23kDa, The quantitative and qualitative analysis using HPLC technique was without significant differences and the used of HPLC assay as an additional confirm purification step.

The study was conducted at the Dujail region, north of Baghdad, during the spring season of 2022, to identify the rate of downy mildew infection and the residues of Elite (fungicide) on the cucumber cultivated in the regular greenhouses compared to the greenhouse with three ventilation openings. The regular greenhouse was sprayed with Elite pesticide, twice; the 1st treatment sprays was after 7 days of infection onset, and the 2nd spray was 30 days after the 1st treatment. The residuals of Elite were, then, estimated. In regards to the 2nd greenhouse, three ventilation openings were made after the first observation of the disease. The average temperature and a relative humidity (8˚C and 97%, respectively) were reported from the onset of the downy mildew infection on the cucumber. After 2 months, the average of the infection percentage was reported in the regular greenhouse was 1.95%, with a significant difference from the average of percentage the infection in the house of three ventilation openings, which was 1.28%. The average of the Elite residues after three days of spraying was 50, 40 and 28 mg/kg of the cucumber varieties; Mustaqbal, Jamila and Faris, respectively. On the 7th day of spraying, the average of the Eilit residue was 11mg/kg of the three cucumber varieties. The total production rate of cucumber fruits at the regular greenhouse was 1800 kg, for five times harvest, while it was 3000 kg at the greenhouse with three ventilation openings. The authors concluded that the performance of three ventilation holes into the greenhouse at the time infection onset considered a natural control strategy on the downy mildew disease of cucumber. while in the regular greenhouse sprayed with Elite fungicide, the cucumber crop can be harvested after 3d of spraying, when Elite residues were below the allowable limit (60 mg / kg of cucumber fruits).

Inclusion body hepatitis is one of the disease that cause economic loses in poultry industry. Infection with the fowl adenovirus leads to the illness known as inclusion body hepatitis. Affected chickens showed dullness, depression, ruffled feathers and mild greenish diarrhea with low morbidity and high mortality. Seventy-five samples were collected from various areas around Iraq, including Diyala, Karbala and Tikrit, that were thought to be infected with the fowl adenovirus.
The infected chickens ranged in age from 25 to 45 days. After that viral nucleic acid (DNA) was isolated from collected livers. This was followed by testing using conventional PCR by amplification of the Loop 1 gene, which yielded a positive result for the presence of fowl adenovirus. Avian species are at risk of inclusion body hepatitis (IBH) infection, with subclinical infection being the most common type. The study reveals that the liver is affected by a disease that can be diagnosed through necropsy findings such as the presence of multiple genotypes such as FAdV-4, FAdV-8b and E. Molecular tools like PCR offer superior accuracy and sensitivity compared to seroprevalence techniques, which are not specific to the species or type of adenoviruses or their co-infecting illnesses. The current research aimed to clinical diagnosis of adenovirus in chickens and confirmed diagnosis by conventional PCR.
