Bacterial profile and their antimicrobial resistance patterns among patients with community-acquired pneumonia in southwestern Iran.

Background And Objectives: Community-acquired pneumonia (CAP) is one of the most common life-threatening infections, occurring in the community or within the first 48 hours of a patient's hospitalization. The present study aimed to investigate the frequency of pathogenic bacteria and their antibiotic resistance pattern in the sputum of patients with community-acquired pneumonia in Yasuj from 2018 to 2019.

Materials And Methods: In the present study, 128 patients with CAP were included.

Identification and detection of pathogenic bacteria from patients with hospital-acquired pneumonia in southwestern Iran; evaluation of biofilm production and molecular typing of bacterial isolates.

Background: Hospital-acquired pneumonia (HAP) is the second most common nosocomial infection in intensive care units (ICUs). The present study aims to determine the prevalence of pathogenic bacteria, their biofilm formation, and molecular typing from patients with HAP in southwestern Iran.

Methods: Fifty-eight patients with HAP participated in this cross-sectional study.

Antimicrobial Susceptibility Pattern in the Bacteria Isolated from Surgical Site Infection: Emphasis on Staphylococcus Aureus; Yasuj City, Southwest Iran.

Background: Surgical site infections (SSIs) in surgical wards remains the most common cause of postoperative complications and realistically is the third most common origin of healthcare-related conditions. Staphylococcus aureus is undoubtedly the most common bacteria causing SSIs. The current study aimed at investigating the antimicrobial susceptibility pattern in bacteria isolated from SSIs, evaluation of tetracycline resistance genes, and SCCmec typing in S.

Sonochemical incorporated of cytosine in Cu-Hbpdc as an antibacterial agent against standard and clinical strains of Proteus mirabilis with rsbA gene.

The cytosine embedded copper based metal-organic framework (Bio-MOF) was synthesized by facile one-step sonochemical method by simply mixing of 4-4, biphenyldicarboxylic, cytosine and copper nitrate (Bio-Cu-Hbpdc-Cy). The prepared bio-MOF was characterized by XRD, FTIR and FE-SEM techniques. The effect of Cu-Hbpdc-Cy on the expression of the rsbA gene was evaluated in the clinical and standard Proteus mirabilis and study of MIC of Cu-Hbpdc-Cy by microdilution against them that have the rsbA gene.

The frequency of Klebsiella pneumonia encoding genes for CTX-M, TEM-1 and SHV-1 extended-spectrum beta lactamases enzymes isolated from urinary tract infection.

Background: The extended- spectrum β-lactamase producing bacteria are widely spread worldwide. The productions of these enzymes cause bacterial resistance to a wide range of antibiotics. The aim of this study was to investigated the frequency of K.

Sonochemical-solvothermal synthesis of guanine embedded copper based metal-organic framework (MOF) and its effect on oprD gene expression in clinical and standard strains of Pseudomonas aeruginosa.

The guanine incropped Cu based metal-organic framework (Guanine-Cu-MOF) was synthesized by facile one-step sonochemical method by simply mixing of 4-4, biphenyldicarboxylic, guanine and copper nitrate (Bio-Cu-Hbpdc-Gu). The prepared guanine-MOF was characterized by using X-Ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and Field emission scanning electron microscopy (FE-SEM) techniques. The morphology of prepared material was sponge-shaped which it was well documented, together with the presence of existing functional groups.

Genetic similarity between adenoid tissue and middle ear fluid isolates of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis from Iranian children with otitis media with effusion.

Background: Otitis media with effusion (OME) is a common disease among children, in the pathogenesis of which bacterial infections play a critical role. It was suggested that adenoid tissue could serve as a reservoir for bacterial infection, the eustachian tubes being the migration routes of bacteria into the middle ear cavity. The aim of this study was to investigate the genetic similarity between isolates of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis, obtained from adenoid tissue and middle ear fluid.

Hepatitis B Infection among high risk population: a seroepidemiological survey in Southwest of Iran.

Background: Hepatitis B virus (HBV) infection remains a major global health problem. This study aimed to assess the prevalence and risk behaviors for HBV infection among high risk groups in Kohgiloyeh and Boyerahmad province, in Southwest of Iran.

Methods: Blood samples were collected from 2009 subjects, between 2009 and 2010 in Kohgiloyeh and Boyerahmad province, in southwest of Iran.

Characterization of Alloiococcus otitidis strains isolated from children with otitis media with effusion by Pulsed-Field Gel Electrophoresis.

Objective: Alloiococcus otitidis is a slow growing organism which has been isolated in a few studies on patients with otitis media with effusion (OME). According to the literature review, there is no study about the molecular typing of A. otitidis.

High prevalence of hepatitis C infection among high risk groups in Kohgiloyeh and Boyerahmad Province, Southwest Iran.

Background: Detection of Hepatitis C virus (HCV)-infected people in each community assists with infection prevention and control.  This study aims to evaluate the prevalence of HCV infection among high risk groups in Kohgiloyeh and Boyerahmad Province, Southwest Iran.

Methods: This was a cross-sectional study conducted from 2009-2010 in Kohgiloyeh and Boyerahmad Province.

Evaluation of crude sesquiterpenoid extract of Phellinus fastuosus as a natural preservative.

It has been revealed that the use of synthetic food preservatives has variety of various side effects and hence search of safe and effective natural preservative has become a need. With the afore said objective the present study to screen the possibility of using sesquiterpenoid extract of local folk mushroom Phellinus fastuosus as food preservative was undertaken. Microbial growth inhibition by sesquiterpenoid extract of Phellinus was evaluated in the media with natural ingredient such as milk agar (MA), tomato juice agar (TJA), wheat flour agar (WFA) and pineapple juice agar (PAJA) with the composition with Phellinus extract, sodium benzoate and combinations.
