Phenotypic and genotypic identification of class C and D β-lactamases in clinical isolates of : a cross-sectional study.

Background And Aims: The emergence of () antibiotic resistance is an important public health problem worldwide that can negatively affect infection control. Therefore, obtaining knowledge about antibiotic resistance mechanisms is necessary for infection control policies. This study aimed to determine the frequency of class C and D β-lactamases in strains isolated from patients referred to Ardabil hospitals using phenotypic and genotypic tests.

Serogroup distribution, diversity of exotoxin gene profiles, and phylogenetic grouping of CTX-M-1- producing uropathogenic Escherichia coli.

The emergence of CTX-M-1 producing Uropathogenic Escherichia coli (UPEC) has become a serious challenge. In addition to antimicrobial resistance, a number of virulence factors have been shown. Therefore, this study was designed to determine the prevalence of O- serogroups, phylogenetic groups, exotoxin genes, and antimicrobial resistance properties of CTX-M-1- producing UPEC.

Chemical Composition and Antimicrobial and Cytotoxic Activities of Foeniculum vulgare Mill Essential Oils.

Background And Aim: Foeniculum vulgare (F. vulgare) Mill, commonly known as fennel, belongs to the Umbelliferae (Apiaceae) family, biennial or perennial herbs disseminated in Mediterranean region and central Europe. This herbal medicine (HM) is considered as a traditional HM, and its parts have been studied.

Bacterial l-asparaginases for cancer therapy: Current knowledge and future perspectives.

l-Asparaginases hydrolyzing plasma l-asparagine and l-glutamine has attracted tremendous attention in recent years owing to remarkable anticancer properties. This enzyme is efficiently used for acute lymphoblastic leukemia (ALL) and lymphosarcoma and emerged against ALL in children, neoplasia, and some other malignancies. Cancer cells reduce the expression of l-asparaginase leading to their elimination.

Characterization of uropathogenic E. coli O25b-B2-ST131, O15:K52:H1, and CGA: Neutrophils apoptosis, serum bactericidal assay, biofilm formation, and virulence typing.

Pathogenic and drug-resistant strains of Escherichia coli (E. coli) O25b-B2-ST131, O15:H1-D-ST393, and CGA (clonal group A) clonal groups have spread worldwide. This study aimed at determining E.

Herbal medicine as an auspicious therapeutic approach for the eradication of Helicobacter pylori infection: A concise review.

Helicobacter pylori (H. pylori) causes gastric mucosa inflammation and gastric cancer mostly via several virulence factors. Induction of proinflammatory pathways plays a crucial role in chronic inflammation, gastric carcinoma, and H.

Mycobacterium avium paratuberculosis and Mycobacterium avium complex and related subspecies as causative agents of zoonotic and occupational diseases.

Mycobacterium avium complex (MAC) and Mycobacterium avium paratuberculosis (MAP) cause zoonotic infections transmitted by birds and livestock herds. These pathogens have remained as serious economic and health threats in most areas of the world. As zoonotic diseases, the risk of development of occupational disease and even death outcome necessitate implementation of control strategies to prevent its spread.

Sero-prevalence of Infection in Neyshabur, Iran, During 2010-2015.

Backgrounds & Objective: The prevalence has continuously decreased during recent years in Iran. The current study aimed at determining . prevalence in Neyshabur city, Northeast Iran, during 2010-2015.

Seroepidemiology of HTLV-1 and HTLV-2 Infection in Neyshabur City, North-Eastern Iran, during 2010-2014.

Background: Retroviruses of human T-lymphotropic viruses (HTLV-1 and HTLV-2) have been demonstrated to be endemic in the north-eastern region of Iran. This study was aimed to determine the HTLV-1 and HTLV-2 prevalence among healthy individuals in Neyshabur City during 2010-2014.

Methods: A total of 8054 blood samples were collected from healthy participants in Neyshabur, North-Eastern Iran.

Occurrence of SHV, TEM and CTX-M β-Lactamase Genes Among Enteropathogenic Escherichia coli Strains Isolated From Children With Diarrhea.

Background: Antibiotic resistance is widespread among diarrheagenic Escherichia coli in developing countries, where the overuse of antibiotics is common. Information regarding β-lactamases, especially Extended-Spectrum β-Lactamases (ESBLs) in diarrheagenic pathogens should be considered in clinical management when an optimal treatment is needed.

Objectives: The main objective of this study was to investigate the prevalence of bla CTX-M , bla SHV and bla TEM β-lactamase genes among enteropathogenic E.
