We evaluated the antibiotic-resistance genes in isolates from patients in Erbil hospitals.Methodology: This is the first study to demonstrate the antimicrobial resistance epidemic in Erbil, Iraq. A total of 570 patients, including 100 COVID-19 patients were tested. Isolate identification, characterization, antibiotics susceptibility test, polymerase chain reaction (PCR) amplification of the antibiotic resistance genes in both bacterial chromosome and plasmid, 16S-23S rRNA gene intergenic spacer (ITS) sequencing using the Sanger DNA sequencing, and phylogenetic analysis were used in this study.Results: Only 13% of A. baumannii isolates were from COVID-19 patients. All isolates were multi-drug resistant due because of 24 resistance genes located in both the bacterial chromosome or the plasmid. blaTEM gene was detected in the isolates; however, aadB was not detected in the isolated bacteria. New carbapenemase genes were identified by Sanger sequencing and resistance genes were acquired by plasmids.Conclusions: The study identified metabolic differences in the isolates; although all the strains used the coumarate pathway to survive. Several resistance genes were present in the isolates' plasmids and chromosome. There were no strong biofilm producers. The role of the plasmid in A. baumannii resistance development was described based on the results.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 9.1","pages":"S56-S66"},"PeriodicalIF":1.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142584862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This panel could simultaneously detect a broad range of gene loci of SARS-CoV-2, and genes for the most common infectious viruses that affect the respiratory tract, in a single run and could include up to 96 samples. Four hundred and forty-eight samples and 31 control samples were analyzed independently with both TSP and RT-PCR, and the results were compared for accuracy and other indicators.Results: TSP identified 50 SARS-CoV-2 positive samples with a 99.33% match to RT-PCR results. It is not surprising that TSP also identified multiple infections from the 96 samples, whereas RT-PCR could not.

It is crucial to identify biomarkers that can aid in predicting patients' prognosis and mortality. This study evaluated the relationship between galectin-3 (Gal-3), interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) levels and the prognosis and mortality of COVID-19 patients.Methodology: The study included 69 COVID-19 patients (32 outpatients, 37 inpatients) and 19 healthy controls. Gal-3, IL-1, IL-6, and TNF-α levels in serum samples were measured using an ELISA test.Results: In a comparison between the patient and healthy control groups, it was observed that the patient group had significantly higher levels of Gal-3, IL-6, and TNF-α. Comparison between the outpatient and inpatient groups revealed that the hospitalized patient group had significantly higher levels of IL-6 and TNF-α, while the Gal-3 levels were lower in this group. In the analysis of subgroups to assess disease severity, critical COVID-19 patients exhibited elevated levels of Gal-3 and IL-6 compared to those with severe COVID-19. Moreover, Gal-3 and IL-6 were identified as having predictive value for mortality in hospitalized patients, while both IL-6 and TNF-α demonstrated diagnostic accuracy across all patient groups.Conclusions: The study results indicate that the levels of IL-6 TNF-α play a crucial role in determining the hospitalization and mortality of COVID-19 patients. Additionally, it was observed that Gal-3 and IL-6 levels can be utilized to assess the severity of the disease and predict mortality in patients who require hospitalization.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 9.1","pages":"S33-S39"},"PeriodicalIF":1.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142583664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to determine the differences between early and late ICU admission.Methodology: A retrospective cohort study of patients with COVID-19 pneumonia at two high-complexity hospitals in Colombia. Early ICU admission (EICUA) was defined as direct admission from the emergency department or within the first 24 hours of admission. Late ICU admission (LICUA) was defined as admission from the hospitalization service after 24 hours of arrival. A robust Cox regression was performed for the variable recovery time, to determine the impact of the ICU admission type in the hazard rate.Results: 68.2% were EICUA patients and 31.8% were LICUA patients.

Fifty patients diagnosed with COVID-19 and 50 controls were recruited and genotyped for the selected gene variants.Results: The OAS1 gene rs2660 exhibited an association with COVID-19 susceptibility in various genetic models. The risk decreased with AG genotype (OR = 0.23, 95% CI = 0.09-0.58; p = 0.0011) compared to GG in codominant models. In dominant (OR = 0.35, 95% CI = 0.15-0.81; p = 0.013) and overdominant (OR = 0.21, 95% CI = 0.08-0.53; p = 0.0005) models, the single nucleotide variant (SNV) decreased COVID-19 susceptibility risk. There was no association of OAS1 rs2660 genotypes with COVID-19 severity. We did not find a significant association between MxA rs2071430 variant and COVID-19 susceptibility.Conclusions: OAS1 rs2660 AG genotype showed decreased risk of COVID-19 susceptibility among Pakistani patients. This study provides insight into the role of the OAS1 and MxA variants in COVID-19. This finding could aid researchers in understanding genetic susceptibility and severity in COVID-19 by identifying at-risk individuals and determining the optimal treatment.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 9.1","pages":"S147-S152"},"PeriodicalIF":1.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142583280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
