Detection of Some Antibiotic-Resistance Genes (qnrB, qnrS, parE, and armA) for Escherichia coli Isolated from Tigris River, Baghdad, Iraq Israa Abd Hussein, Adel Hussain Talib, Saad Sabah Fakhry Iraqi Journal of Science, 2026 Safe water is a crucial resource for the survival and sustenance of life, and its scarcity is a major cause of water-related ailments, particularly in underdeveloped nations. The aim of this study was to determine the antibiotic sensitivity pattern of Escherichia coli isolated from the surface waters of the Tigris River and the detection of resistance genes (qnrB, qnrS, parE, and armA) for E. coli. A total of 32 bacterial isolates of E coli were collected for analysis from four distinct sites: S1 Al-Muthana Bridge, S2 Al-Sarrafia Bridge, S3 Al-Senak Bridge, and S4 Al-Jadriyah Bridge. Water samples were collected from November 2023 until July 2024. The isolation of E. coli is performed using membrane filtration techniques and biochemical analysis followed by the VITEK2. The antimicrobial susceptibility of E. coli isolates was assessed using the Kirby-Bauer disk diffusion method, employing a selection of 10 specific antibiotics for evaluation. The resistance genes for E. coli isolates were detected using the PCR technique. The results showed that both nitrofurantoin and ampicillin showed significantly higher resistance (100%), significant proportions of resistance to some β-lactam antibiotics (ceftazidime, cefoxitin, and ampicillin were 94%,94%,100% respectively) , another significant resistance for aminoglycosides antibiotics ( gentamycin and amikacin, 81-84%), cephalosporins antibiotics group showed significant differences ( ceftriaxone and cefuroxime , 59-93.8%), carbapenems antibiotics ( imipenem,72%), quinolones group presented low resistance proportion ( ciprofloxacin, 43.8%). All identified genes are complete sets with two, three, or four genes. Fourteen isolates showed resistance to fluoroquinolones (ciprofloxacin), and 26 showed resistance to aminoglycosides (gentamycin). Nine isolates (28.1%) showed the presence of qnrB, and 7 isolates (21.9%) showed the presence of qnrS genes. Of the 26 resistant isolates to gentamycin, 20 isolates (62.5%) showed the presence of the armA gene, and the parE gene was found among all selected isolates for fluoroquinolones and aminoglycosides (100%). The double association qnrB and qnrS was found in 12 isolates (37.5%), This research highlights the necessity of implementing regular surveillance of urban rivers to control the spread of antimicrobial resistance (ARM) genes in aquatic environments.
Seasonal and Spatial Evaluation of Euphrates River Water Quality Using Chemical and Physical Indicators and Multivariate Analysis in Karbala, Iraq Zainab Altameemi, Adel H. Talib, Saad S. Fakhry Iraqi Geological Journal, 2026 The increased demand for water for both private and public use as the population grows. However, human activities have contributed to a decline in water quality. The objective of this study was to evaluate the water quality of the Euphrates River. Samples of water were gathered at four distinct places of the Euphrates River throughout the rainy and dry seasons of 2023/2024. Standard techniques were used to analyze twelve physical-chemical water quality parameters: water temperature, air temperature, electrical conductivity, hydrogen ion concentration, total dissolved solids, salinity, total suspended solids, dissolved oxygen, turbidity, biological oxygen demand 5, total phosphorus, and total nitrogen. Certain parameters, including water temperature, turbidity, total dissolved solids, biological oxygen demand, total phosphorus, and total nitrogen, exceeded the recommended limits. Several variables showed a statistically significant variation between the sampling seasons. Regarding the study sites, the findings showed notable variations in total dissolved solids, turbidity, total suspended solids, and hydrogen ion concentration. Water temperature-air temperature, total dissolved solids-electrical conductivity, electrical conductivity-Salinity, turbidity-total phosphorus, Salinity-total dissolved solids, and turbidity-total suspended solids show a strong positive association (P ˂ 0.01), whereas water temperature-dissolved oxygen, hydrogen ion concentration-total phosphorus, and hydrogen ion concentration-total nitrogen show substantial negative correlations (P ˂ 0.01). According to principal components analysis, there was a stronger correlation between air temperature, water temperature, biological oxygen demand and hydrogen ion concentration during the dry period. Based on hierarchical clustering, air temperature and Dissolved Oxygen were the most divergent, while electrical conductivity and salinity were the most similar. The Euphrates River's degradation is highlighted in this study, underlining the urgency of taking action to preserve this essential resource for present and future generations.
The effect of deltamethrin insecticide on oxidative stress and liver function in albino male rats and the protective role of citrus peel extraction Hind Bahjat Mohammed Aldik, Adel H. Talib Advancements in Life Sciences, 2026 Background: The study investigates the protective effects of citrus peel extracts (mandarin and lemon) against deltamethrin-induced liver and testicular toxicity in male rats.Methods: Forty-two male rats were divided into 7 groups: Group I (control), Group II (deltamethrin 6 mg/kg), Group III (deltamethrin + mandarin extract), Group IV (deltamethrin + mandarin oil), Group V (deltamethrin + lemon extract), Group VI (deltamethrin + lemon oil) and Group VII (deltamethrin + mandarin + lemon extract). The liver functions and oxidative stress were evaluated by testing biochemical markers (AST, ALT, ALP, SOD and MDA). Evaluation of tissue injury included histopathology of liver and testis.Result: In Group II, Deltamethrin treatment alone increased AST (198.36 U/L), ALT (123.02 U/L), ALP (97.35 U/L), and MDA (83.92 nmol/mL) and decreased SOD (4.72 U/mg) indicating oxidative stress and subsequent tissue damage due to Deltamethrin. In Groups III-VII, the use of citrus peel extracts improved all measured biochemical markers compared to Deltamethrin alone. Group III decreased AST levels to 180.55 U/L, ALT to 114.75 U/L, ALP to 95.49 U/L, and MDA to 75.97 nmol/mL, with SOD levels increasing to 5.95 U/mg. Other treatment groups also showed similar biochemical improvements. The greatest improvement was observed in Group VII (mandarin + lemon extract), showing a decreased AST (162.50 U/L), ALT (85.04 U/L), ALP (90.36 U/L), and MDA (54.98 nmol/mL) as well as an increase in SOD recovery (7.39 U/mg).Conclusion: The extracts of citrus peel reduced liver and testicular toxicity from deltamethrin exposure. The mixture of mandarin and lemon extract produced the most protective ability, due to restoring antioxidant imbalance and reducing biochemical and histological damage. These findings indicate that citrus peel extracts could be a potential natural agent against oxidative stress elicited by pesticide exposure.Keywords:Deltamethrin toxicity, Oxidative stress, Citrus peel extracts, Liver and testicular protection, Biochemical markers
Monitoring the Antibiotic Resistance Development of Escherichia coli in the River Environment: A Systematic Review Zainab A. Altameemi, Adel H. Talib, Saad S. Fakhry Diyala Agricultural Sciences Journal, 2025 One of the major challenges of the twenty-first century is antibiotic resistance in "One Health" humans, animals, and the environment, the spread of which limits treatment options for bacterial infections, increases mortality and causes economic damage. This article aims to offer a critical investigation of the development of antibiotic resistance of E. coli in rivers over the last 10 years. There is increasing interest in monitoring water environments, both surface water and sewage, which are major receptors, sources, and pathways of antibiotic-resistant bacteria (ARB). Additionally, they facilitate the transfer and amplification of ARB. Escherichia coli (E. coli) is a pathogen characterized by an increased level of resistance to antibiotics. A total of 3661 publications in the field of environmental, agricultural, and biological sciences were obtained from two databases (ScienceDirect and PubMed). Most publications in this field have focused on clinical isolates, which has led to a scarcity of information about natural environments, including rivers, which are important freshwater sources. Analysis 31 articles from 20 countries across five continents. The results showed that the highest resistance was against ampicillin (14/31), followed by ciprofloxacin (10/31) in the publications. Regarding antibiotic classes, the fluoroquinolone class showed a significant development in resistance. The development of multidrug resistance of E. coli to beta-lactam antibiotics and fluoroquinolones, such as trimethoprim/sulfamethoxazole and amoxicillin/clavulanic acid, was noted in this review. Additionally, modern resistance to azithromycin and erythromycin was explored.
Spatiotemporal air quality variation between urban and agricultural areas: The influence of climatic factors and pollution dynamics ZAINAB N. ABDULATEEF, ADEL H. TALIB, MAITHAM A. SULTAN Journal of Agrometeorology, 2025 Air pollution is a critical environmental and meteorological concern, significantly influenced by climatic conditions and atmospheric dynamics. Hence, the present study examines seasonal and daily variations in the concentrations of air pollutants, such as CO, SO₂, NOₓ, and O₃, in Baghdad, based on the principle of meteorological influences during the wet and dry seasons. Data were collected at 23 transportation intersections in addition to an agricultural area during morning and afternoon periods. The results indicated a robust relationship between the levels of pollutants and meteorological conditions. Carbon monoxide showed an afternoon peak during the dry season owing to air stagnation (28.2–18.7 ppm). Ozone concentrations also heightened in this season due to increased temperature and photochemical reactions (0.515–0.35 ppm). Levels of ozone, sulfur dioxide and nitrogen oxides reflect over-national air quality standards, with maxima seen in the dry season and more so in the afternoons. The results of the Air Quality Index analysis show that the main factors causing a drastic decrease in quality during the dry season are higher temperatures, scanty rainfall, and increased levels of photochemical activity. This result emphasizes the need to integrate meteorology into urban planning to mitigate pollution.
Effects of meteorological factors on greenhouse gas emissions at traffic intersections in Baghdad: a seasonal analysis ZAINAB N. ABDULATEEF, ADEL H. TALIB, MAITHAM A. SULTAN Journal of Agrometeorology, 2025 Baghdad has experienced notable changes in its climate over recent decades. This study aims to evaluate the impact of meteorological factors, such as temperature, humidity, wind speed on greenhouse gas emissions at traffic intersections in Baghdad city. The study focuses, in particular, on comparing greenhouse gas concentrations during summer (June and July 2023) and winter (January 2024), highlighting how climatic conditions affect the accumulation and spread of these emissions. The results indicated that the greenhouse gas concentrations were much higher during summer than in winter because of high temperatures and strong winds contributing to the accumulation of gases in crowded areas. In contrast, high humidity and weak winds in winter contributed to the accumulation of gases differently. The analysis implies that low humidity during summer months because of heat and drought worsens greenhouse gas emissions, while small thermal changes affect the level of emissions from vehicle fuel. It explicitly shows the pivotal relationship that exists between climate conditions and emissions within a city, further pinpointing the human contribution— especially from traffic—to climate change, therefore meriting attention within urban planning in climate policies regarding emissions.
Assessment of Lung Function in Scavenger Workers at Some Waste Dumpsites in Baghdad City Huda A. Khaleel, Adel H. Talib, Maitham A. Sultan Asian Journal of Water Environment and Pollution, 2024 Waste scavengers face occupational hazards from exposure to toxic landfill emissions, putting them at risk for respiratory illnesses. This study aimed to assess the impacts of landfill gases on lung function in scavengers. Spirometry was used to evaluate lung function in scavengers at 5 dumpsites in Baghdad compared to non-exposed controls. The results showed that winter measurements in the internal measuring point for carbon dioxide indicated that the highest concentration was 454.89 ppm in the Adhamiya landfill and the lowest concentration was 397.65 ppm in the Baghdad Aljadeeda landfill. Lung disease cases were recorded and correlated to landfill sites, work duration, and seasons. The results of the lung efficiency examination showed a clear decrease in spirometry parameters at high-pollution landfill sites with varying concentrations of particulates and gases compared to the control group—more airway restriction cases correlated with increased years of scavenger exposure and higher pollutant levels. As noted, severe respiratory symptoms increased in the summer season likely due to the influence of climatic factors.
