Therefore, living organisms, likewise viruses, can be affected by physical processes. Therapeutic and supportive effects of electric and magnetic fields are proved in numerous studies on cells, bacteria and viruses. In our review, by keeping in mind this potential, we handled the possible curative or supportive and maybe therapeutic potential of electric and magnetic applications on coronavirus patients as short as possible. Studies have given us an idea to review new application methods using electric and magnetic field for coronavirus treatment. While vaccine and drug studies related to this pandemic continue, alternative therapies are also of great importance and new approaches and different perspectives are needed in this regard.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75512808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Management of a patient with urinary tract infection depends on good knowledge of the causative agents and local antimicrobial susceptibility patterns. This study was designed with the aim to investigate the aetiology and antimicrobial susceptibility pattern of uropathogens in children and adolescents at the University of Nigeria Teaching Hospital, Ituku-Ozalla Enugu. Methods and findings: This was a hospital-based cross-sectional study conducted in Department of Medical Microbiology, University of Nigeria Teaching Hospital, Ituku-Ozalla Enugu. The laboratory records of all the mid-stream urine samples of children and adolescents analysed from 2014 to 2019 were reviewed. Urine sample results from neonates were excluded. Information extracted from the records included: age, sex, date of submission of urine samples, provisional diagnosis, microbial isolates and their susceptibility patterns to various antibiotics. Analysis was done using descriptive and inferential statistics. Of 2199 urine samples that were analysed, 650 (29.9%) yielded significant bacteriuria with females accounting for more than half (363/650: 55.8%) of the cases; (χ2=4.204; P=0.040). Isolated organisms were mostly Gram negative bacilli 33.8%) than males (126/650; 19.4%); (χ2=13.009; p<0.001). The least isolated Gram negative organisms was Pseudomonas aeruginosa seen in 20/650 (3.1%) of the urine samples The Gram positives cocci isolated were Staphylococcus aureus (59/650; 9.1%) and Streptococcus species (12/650; 1.9%). Candida spp was also isolated in 32/650; 4.9% of the urine samples. Most of the isolated organisms showed very high resistance to ampicillin and cotrimoxazole. Moderate resistances were seen with nitrofurantoin, cephalosporins, amoxicillin-clavulanic acid and quinolones. The least resistances were shown with carbapenems piperacillin/ tazobactam, linezolid and cefoxitin. Conclusion: The resistance pattern of organisms causing urinary tract infections in children and adolescents to common antibiotics as highlighted in this study is worrisome. Facility specific guideline for antibiotics therapy is urgently advocated for better management of the patients and to ensure good antibiotics stewardship in line with universally accepted standards.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80576017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 1960s, studies had focused on whether DO is the etiological factors of recurrent LUTIs or the inverse. Although the definite correlation between DO and LUTIs have not been proved, urinary microbiota may play a role in genesis of DO that was found by mounting evidences using enhanced urine culture technique and pathophysiological variations of bladder detrusor facilitates bacterial colonization in bladder urothelium. In the future, clarification of correlation between DO and LUTIs needs more scheduled studies and more researches that link the urinary microbiota with Central Nervous System (CNS) function to provide accurately information to help us manage the patients more appropriately.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"62 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77913527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the Antibiotic Resistance (AR) that has recently emerged in bacteria, not only the diagnosis of bacteria but also the determination of the antibiotic resistance has become extremely important. For the determination of AR of bacteria, classical microbiological and biochemistry methods are already applied. However, these methods have many disadvantages in terms of cost and time. With advances in technology as well as molecular biology, a new era has emerged for the accurate determination of AR in bacteria as well. For example, electrochemical methods have been developed recently for the label-free diagnosis of both bacteria and their AR. In this we focus on the issues regarding AR of bacteria and their diagnostic significance.

The early clinical presentation of both viral diseases is quite similar, creating a serious challenge for healthcare providers to discriminate between the two diseases. Recent studies report cases of co-infection as well as cross-reactivity of DENV and COVID-19. Therefore, a retrospective study was designed to identify cases of co-infection/cross-reactivity and its severity based on Liver Function Tests (LFTs). We identified 38 cases of co-infection in a tertiary care hospital in Karachi, Pakistan during the year 2020. These cases were dengue NS-1 Ag or IgM/ IgG antibody-positive along with SARS-CoV-2 RT-PCR positive. The serological profile of co-infected cases revealed that the pattern of dengue serology is mainly based on IgG positivity followed by IgG & IgM positivity. Whereas, a single case of positive NS-1 and a single case of only IgM positive were found. The finding supports that if it is co-infection then might be more common in secondary as compared to primary dengue infection and not causing severe liver damage. This study strongly suggests, to exclude the possibility of cross-reactivity of antibodies in this pandemic condition, dengue infection should be confirmed by using accurate methods (RT-PCR or Virus isolation). Secondly, this study alarms that the dengue-endemic countries are at a higher risk of misdiagnosis of viral infection. Therefore, precautionary measures by the government agencies should be taken in this pandemic situation to reduce dengue infection in future.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84541113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
