Abstract
Tuberculosis (TB) is still one of the leading causes of worldwide death, especially following the emergence of strains resistant to isoniazid (INH) and rifampicin (RIF). This study aimed to systematically review published articles focusing on the prevalence of INH and/or RIF resistance-associated mutations of Mycobacterium tuberculosis isolates in recent years. Literature databases were searched using appropriate keywords. The data of the included studies were extracted and used for a random-effects model meta-analysis. Of the initial 1442 studies, 29 were finally eligible to be included in the review. The overall resistance to INH and RIF was about 17.2% and 7.3%, respectively. There was no difference between the frequency of INH and RIF resistance using different phenotypic or genotypic methods. The INH and/or RIF resistance was higher in Asia. The S315T mutation in KatG (23.7 %), C-15 T in InhA (10.7 %), and S531L in RpoB (13.5 %) were the most prevalent mutations. Altogether, the results showed that due to S531L in RpoB, S315T in KatG, and C-15 T in InhA mutations INH- and RIF-resistant M. tuberculosis isolates were widely distributed. Thus, it would be diagnostically and epidemiologically beneficial to track these gene mutations among resistant isolates.

Abstract
Background and Objectives Microorganisms producing Metallo-Beta-Lactamase (MBL) are a threat and cause of concern as they have become one of the most feared resistance mechanisms. This study was designed to explore the prevalence of MBL production in clinical isolates of Gram negative bacteria using phenotypic MBL detection. Materials and Methods A total of 248 isolates were collected from various clinical samples and were evaluated for carbapenem resistance and MBL production. All strains were screened for MBL production using Double Disk Confirmatory Test (DDCT). Results The results of screening for MBL production using phenotypic disk diffusion method showed that in the 85 isolates were carbapenemase positive; including, 10 (16.1%) Klebsiella pneumoniae, 9 (14.5%) Escherichia coli, 58 (93.6%) Acinetobacter baumannii, and 8 (12.9%) Pseudomonas aeruginosa isolates. Also, 83 (97.6) Carbapenemase-producing isolates were resistant to at least four classes of antimicrobials (MDR). Conclusion A. baumannii was the most common carbapenem resistant bacterium in medical centers in Kermanshah. Significant multiple drug resistance (MDR) incidence was observed compared to different classes of antibiotics.

Abstract
BACKGROUND Clostridioides (Clostridium) difficile is an important infectious pathogen, which causes mild-to-severe gastrointestinal infections by creating resistant spores and producing toxins. Spores contaminated foods might be one of the most significant transmission ways of C. difficile-associated infections. This systematic review and meta-analysis study were conducted to investigate the prevalence of C. difficile in food. METHODS Articles that published the prevalence of C. difficile in food in PubMed, Web of Science, and Scopus databases were retrieved using selected keywords between January 2009 and December 2019. Finally, 17,148 food samples from 60 studies from 20 countries were evaluated. RESULTS The overall prevalence of C. difficile in various foods was 6.3%. The highest and lowest levels of C. difficile contamination were detected to seafood (10.3%) and side dishes (0.8%), respectively. The prevalence of C. difficile was 4% in cooked food, 6.2% in cooked chicken and 10% in cooked seafood. CONCLUSIONS There is still little known concerning the food-borne impact of C. difficile, but the reported contamination might pose a public health risk. Therefore, to improve the food safety and prevent contamination with C. difficile spores, it is necessary to observe hygienic issues during foods preparation, cooking and transfer.

Abstract
The incidence of Mycobacterium tuberculosis (MTB) is increasing due to lack of appropriate diagnostic and therapeutic methods. Therefore, early and accurate detection of this bacteria plays a significant role in controlling tuberculosis. This study aimed to design, develop, and implement a direct and rapid detection method of MTB using modified gold nanoparticle (AuNP) colorimetric probe-based biosensor in sputum specimens. Spherical AuNPs were synthesized by the citrate reduction method and were functionalized using thiol-modified oligonucleotides (AuNP-biosensor). AuNP-biosensor and IS6110 PCR were compared to the gold standard in terms of analytical and clinical sensitivity and specificity, positive predictive value (PPV), negative predictive value (NPV), diagnostic odds ratio (DOR), and accuracy in 52 clinical specimens. Gold standard was defined as a positive result in concentrated sputum smear microscopy (SSM), culture, or Xpert MTB/RIF.The AuNP-biosensor had 100% sensitivity and specificity for detection of total sputum DNA in less than 15 min with ready-to-use AuNP-biosensor. PPV, NPV, DOR and accuracy of this method were 100%, 100%, 2325 and 100%, respectively. Considering the promising results of the diagnostic value indices of the AuNP-biosensor, the designed method is an affordable, rapid, reliable, and cost-beneficial way for direct detection of MTB in sputum specimens.

Abstract
Background: Hepatitis C virus (HCV) infection as a serious medical issue is one of the most important pathogens of the human. Youngsters with thalassemia who get blood transfusions are endangered with a high risk of HCV contamination.
Objective: This review intended to study the predominance of HCV among thalassemia patients in Abadan, Khuzestan, in the south-west of Iran.
Materials and Methods: For this study, a specific questionnaire on demographic information (age, number of blood transfusions) was completed by trained personnel based on acquired information from patient records, and also blood samples were taken at the same time in order to check the presence and level of anti-HCV antibodies.
Results: As a result, it was shown that from 179 patients 20 (11.17%) were positive for anti-HCV antibodies.
Conclusion: The HCV infection is an illness which influences extensive number of thalassemia patients in the world. The Lack of knowledge about blood safety and HCV infection as the most predominant illness transmitted with contaminated blood in thalassemia patients is a major threat to public health in a group of countries including Iran and the data are mostly obtained from provinces of Iran. The prevalence of HCV infection in patients with thalassemia who live in Khuzestan province is less than that in other provinces of Iran and also neighbour countries; and researchers should pay attention to hepatitis C infection in order to prevent thalassemia cases.

Abstract
BACKGROUND The emergence of multidrug-resistant Acinetobacter baumannii complicates the therapy of the related infections. Hospital isolates of A. baumannii are usually multidrug-resistant. The problem is compounded by increasing resistance to broad-spectrum antibiotics including carbapenems. OBJECTIVES The aim of this study was to determine antimicrobial susceptibility patterns and distribution of bla OXA -type carbapenemases genes among A. baumannii isolates from hospitalized patients in Shiraz, Southwest Iran. MATERIALS AND METHODS Two hundred A. baumannii isolates were recovered from different clinical specimens in four Shiraz teaching hospitals. Isolates were detected as A. baumannii by Microgen kit and PCR with specific primers of bla OXA-51-like gene. Antimicrobial susceptibility testing was determined by disk diffusion method for all the isolates. Multiplex PCR assays were performed for detection of bla OXA-23-like , bla OXA-24-like and bla OXA-58-like genes. RESULTS All the isolates were susceptible to colistin and polymyxin B. Moreover, all of them were resistant to piperacillin, piperacillin-tazobactam, ampicillin, ceftazidime, cefoxitin and aztreonam. Eighty (40%) isolates had positive results for bla OXA-23-like , 14 (7%) for bla OXA-24-like and 1 (0.5%) isolate for bla OXA-58-like . The co-existence of studied genes was detected for bla OXA-23-like plus bla OXA-24-like in nine (4.5%) isolates. CONCLUSIONS The prevalence of carbapenem resistant A. baumannii isolates in Shiraz hospitals is high. The bla OXA-23-like gene was the most frequent carbapenemase identified among resistant A. baumannii isolated in Shiraz hospitals. The increasing incidence of A. baumannii is a serious concern, therefore control of this pathogen and taking preventive measures are emphasized.
