A case report of a mucormycosis caused by Lichtheimia ramosa in a patient with acute myeloid leukemia
We present a fatal case of mucormycosis, affecting a 59-year-old woman with diabetes and acute myeloid leukemia. Palatal mucormycosis with sinonasal invasion was confirmed by mycological culture and histopathology. Exact species identification of Lichtheimia ramosa was performed by PCR-sequencing of ITS1-5.8S- ITS2 regions of the ribosomal genes. The patient was managed medically as surgical approach was not possible, and she unfortunately died. To our knowledge, this is the first report of Lichtheimia ramosa infection in Tunisia confirmed molecularly. (Source: Reviews in Medical Microbiology)

Antibacterial, antibiofilm, and antipersister cells formation of green synthesis silver nanoparticles and graphene nanosheets against Klebsiella pneumoniae
The present work aimed to investigate the antibacterial, antibiofilm, and antipersistence effect of silver nanoparticles (AgNPs) green synthesis, graphene nanosheets, and graphene–silver nanocomposite against Klebsiella pneumonia. Fifty isolates of K. pneumoniae were collected from different clinical specimens and identified using the Vitek-2 system (BioMe’rieux, France). The antibacterial effect of green AgNPs, graphene nanosheets, and graphene–silver nanocomposite on persistence K. pneumonia isolates were detected using agar well diffusion assay. The minimum inhibition concentrations was employed by using the 96-we...

Molecular typing, virulence traits and risk factors of pandrug-resistant Acinetobacter baumannii spread in intensive care unit centers of Baghdad city, Iraq
Objective:
The virulence traits of pandrug-resistant (PDR) Acinetobacter baumannii strains have not been fully disclosed. Our aim was the assessment of PDR-A. baumannii (PDR-AB) virulence traits and risk factors in the intensive care unit (ICU), Baghdad, Iraq.
Methods:
Among 689 samples, 200 of them were identified as A. baumannii. In the disk diffusion test, 150 of them were PDR-AB. The virulence factors and antibiotic resistance genes were screened using the polymerase chain reaction (PCR) technique. Pulsed-field gel electrophoresis (PFGE) was performed for genetic typing of strains.
Results:
The age ra...

Correlation of arginine metabolism with neurodegenerative diseases in infected cells with herpes simplex virus-1
In this study, it has been shown that most of the key enzymes involved in arginine metabolism in HEK 293-infected cells with HSV-1 has changed in MOIs 1 and 5. These changes are great along with changes in neurodegenerative diseases. Change in arginine metabolism key enzymes mRNA expression after infection with HSV-1 can reflect one of the most important mechanisms of HSV-1 involvement in neurodegenerative diseases.

Phenotypic and molecular characterization of antimicrobial resistance in Staphylococcus epidermidis strains isolated from urinary tract infections and bovine mastitis
In this study, the prevalence of resistance to a wide range of antibiotic agents and the presence of virulence factors amongst S. epidermidis strains were observed. Failure to pay attention to the antibiotic-resistant strains of S. epidermidis can be a serious warning to the health of the community. (Source: Reviews in Medical Microbiology)

Detection of efflux pump genes conferring multidrug resistance in clinical isolates of Acinetobacter Baumannii in Tehran province
Conclusion:
The majority of A. baumannii isolates had antibiotic efflux pumps, and more than 73% of A. baumannii isolates were indicated to be resistant to the target antibiotics, indicating the significant role of efflux pumps in the development of resistance against these antibiotics.

Determination of virulence and quinolone resistance genes and biofilm production among uropathogenic Escherichia coli strains isolated from clinical specimens in Iran
Conclusion:
The fact that the infection can be highly affected by virulence factors of E. coli, let us to conclude that in the case of signs and symptoms of urinary tract infection, it is better to avoid wide use of antibiotics. (Source: Reviews in Medical Microbiology)

Detection of qnrA, qnrB, and qnrS genes in Klebsiella pneumoniae and Escherichia coli isolates from leukemia patients
This study indicated that the high frequency of antibiotic resistance, qnrA, qnrB, and qnrS-producing E. coli and K. pneumoniae isolates, could be a major concern and further studies are needed for infection control measures in the patients affected by leukemia disease in Iran.

The association between diversity and composition of vaginal microbiota of Iranian women with and without human papillomavirus infection
In this study, 69 vaginal samples with and without manifestation of HPV were obtained from women referring to a gynecology clinic and extracted DNA was introduced to real-time PCR looking for the HPV serotypes and bacterial load by using bacterial 16S rRNA gene.
Results:
Out of 64 samples, 16 isolates were normal, 13 isolates were clearance or HPV-negative, and 16 isolates were persistence or HPV-positive. Lactobacillus spp. is the predominant vaginal microbiota in normal women and its count became lower at HPV-negative and finally became zero at HPV-positive group. We could approve a significant increase in the col...

Coronavirus disease 2019: fundamentals, chronology and vaccine evolution
The coronavirus disease 2019 (COVID-19) is caused by a novel coronavirus, which is recognized as Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The recent pandemic caused by SARS-CoV-2 is a concern of major public health emergency globally. The virus is highly contagious, enters through nasopharyngeal route into lungs and infects respiratory tracts and later disseminate to other organs in the body. If body immune response fails to eliminate or over responds to infection in affected persons, the condition turns to severe acute respiratory syndrome or pneumonia, multiple organ failure, septic shock and finally...

Multiple locus variable number tandem repeat analysis of Acinetobacter baumannii strains isolated from human clinical and animal meat samples
The current research was done to study the prevalence rate and molecular typing of Acinetobacter baumannii strains isolated from human and animal samples. One-hundred and seventy-four animal meat and 128 human clinical samples were collected and subjected to bacterial culture. A. baumannii isolates were confirmed using the Loop-mediated isothermal amplification. Approved strains were subjected to molecular typing using the multiple-locus variable number tandem repeat analysis method. Forty-four out of 174 (25.28%) raw meat and 64 out of 128 (50%) human samples were positive for A. baumannii strains. Ovine meat (39.28%) and...
