Abstract
Abstract Background and objectives: Influenza virus is the sixth cause of death in the world. We cannot differentiate it from other respiratory viruses upon clinical signs alone. This study was aimed at determining the frequency of influenza A&B antigen in pharyngeal secretion of children with upper Respiratory Infection (URI). Materials and methods: This cross sectional -descriptive study was done in pediatrics clinic of Rasoul hospital and Shahid Heidari clinic, Tehran (2006-2007). We studied the immunochromatography 149 children aged less than 14 years with URI. Rapid test was performed on pharyngeal samples of all cases. We used independent T test to compare the means of variables. (CI 95%, p<0.05). Results: The Signs of the studied children are fever (58.4%), sore throat (60.4%), coughing, runny nose and hoarseness (45%) and gastric signs (<20%) while in Influenza cases, they are 86.7%, 40% and 40% respectively. Fifteen (10.1%) of the subjects have positive rapid influenza test. The average age of the influenza case is 80 months, which is not significantly different from non-influenza cases. While no under one-year-old child has Positive influenza test, by increasing age the number of positive test is increased. As the frequency in children, aged over 10 is increased to 15.4%. There is significant difference between positive influenza test and signs such as fever, sore throat and previous antibiotic usage (p<0.5). Conclusion: Although this study was not done in epidemic period for influenza, it indicated Influenza as the etiology of 10.6% of URI. Since the cost for prevention and treatment of influenza is high and drug resistance is problematic, we can decrease the URI in non-epidemic period by mass vaccination in children, at least in high-risk cases. Key words: URI (upper respiratory infection), Influenza virus, rapid Immunochromatography Influenza test, Influenza vaccine.

Abstract
Background and Objective: Respiratory tract infections (RTI) are the most common infectious disorders, worldwide. About 80%-90% of RTI are caused by four viruses such as Adenoviruses, 51 serotypes have been introduced so far. The aim of this survey was to evaluate the frequency of Adenovirus in respiratory infected patients by PCR method in Golestan province, Iran.
Material and Methods: This descriptive cross-sectional study was conducted on 400 patients with clinical diagnosis of flu-like respiratory infection, 2010-2012. In addition to collecting demographic and clinical data, nasopharyngeal swabs were taken and transferred to the virology laboratory in viral transport medium (VTM), and evaluated by PCR method for Adenovirus after genomic extraction. Using SPSS v.11 software, we analyzed the data.
Results: Thirty-seven (9.2 %) were positive for Adenovirus. No significant correlation was found between being positive for Adenovirus and the variables such as age, gender and season. Clinical signs were coughing (27 73%), body pain (25 67.6%), and fever (24 64.9%). Thirty-five of the patients (94.5%) had at least one symptom.
Conclusion: Our findings are consistent with other research conducted in Iran and other countries. There is a significant correlation between Adenovirus infection and clinical symptoms.

Abstract
Background and Objective: Influenza is an acute respiratory infection caused by Influenza virus with three kinds of A, B and C . This virus spreads througout the world and produce some epidemics with different intensities . This study aimed to determine the prevalence of influenza B in patients reffering to health centers.
Material and Methods: this study was conducted on 878 samples in 2011-2013. Using PureLinkTM Viral RNA/DNA Kit, Influenza-RNA was extracted. Then Influenza B was distinguished by using SuperScript III Platinum, Quantitive Real Time PCR System from InvitrogenTM , specific primers and probs.
Results: the rate of Influenza B positive was %5.58 of the patients that %55.10 of them were female and %44.89 male. The highest rate was related to 31-40 and 51-60 year old patients.
Conclusion:
given the prevalence of influenza B virus and lack of genetic changes , it is recommended that a proper vaccine for improving immunty and effective drugs for treatmet be used.

Abstract
ABSTRACT
Background and Objective: Lophomonas blattarum is a multi-flagellate protozoan that is commensal in hindgut of cockroaches and other insects. The protozoan can cause respiratory infection in humans. Most cases of the infections with this protozoan have been reported in China. Here, we present a case with chronic respiratory allergy caused by
L. blattarum in Golestan province, Iran.
Case Description: The case was a 37-year-old male with history of respiratory conditions and he was immunocompetent. An athlete.
L. blattarum was detected in direct smear examination of sputum,
Conclusion: Since we found respiratory infection in an immunocompetent individual who was also an athlete, it is necessary to study this parasite and its life cycle and transmission methods. It is also suggested to consider
L. blattarum infection and treatment with metronidazole in cases of chronic allergies, especially those that do not respond to treatment.

Abstract
ABSTRACT
Background and objectives: Coronaviruses are the main causes of respiratory tract infections in humans. They are also the second leading cause of common cold after rhinoviruses, and can lead to otitis media and asthma. The aim of this study was to investigate the molecular detection of coronaviruses in clinical samples of patients with flu-like symptoms.
Methods: Specimens were taken from 297 patients with flu-like symptoms who were referred to the influenza laboratory of Golestan University of Medical Sciences during 2012-2014. RNA was extracted from the specimens using an RNA extraction kit. Accordingly, RNA was used for cDNA synthesis and GAPDH was used as the internal control. Synthesized cDNA was investigated for presence of human coronaviruses genome with real-time polymerase chain reaction using specific primers. Data were analyzed by SPSS 16.0 software.
Results: The coronavirus genome was not detected in the specimens of patients with flu-like symptoms.
Conclusion: Genome of human coronaviruses is absent in samples from patients with upper respiratory tract infections and influenza-like symptoms, which may indicate the low prevalence of the virus in the Golestan Province, Iran.
KEYWORDS: Human coronaviruses, Upper respiratory tract infection, Golestan Province.

Abstract
Background and Objectives: Moraxella catarrhalis is considered as an emerging pathogen and a new nosocomial infection agent. This study was conducted to isolate and identify M. catarrhalis from clinical samples (respiratory tracts) and assess them for antimicrobial susceptibility patterns.
Methods: In total, 280 samples were collected from patients with respiratory tract infection, and 120 samples were obtained from healthy individuals in the control group. The isolates were identified by phenotyping and genotyping methods, and their antibiotic susceptibility was evaluated using disk diffusion methods. The presence of β-lactamase and efflux pump activity were specified via phenotypic methods. Finally, Bro and acrA genes in the isolates were detected by PCR technique.
Results: The frequency of this bacterium was 9.64% (27 out of 280) in patients with respiratory tract infection and 4.16% (5 out of 120) in the control group. Although the isolates were resistant to penicillin, they had various responses against other antibiotics. The results obtained from molecular method showed that 90.6% and 84.3% of the isolates possessed Bro and acrA genes, respectively. There was a significant relationship (P<0.05) between the presence of Bro and acrA genes and antibacterial resistance to ampicillin, amoxicillin, cefazolin, cefuroxime, and chloramphenicol.
Conclusion: Our findings confirmed the existence of M. catarrhalis in patients with respiratory diseases and the high prevalence of antibiotic resistant genes in M. catarrhalis isolates. Therefore, timely diagnosis and successful treatment can play important roles in preventing their spread.

Abstract
Introduction: Bronchopulmonary lophomoniasis is an infrequent occurrence. In this study, we document a singular instance of pulmonary lophomoniasis exhibiting unconventional manifestations in Golestan province, Iran.
Case presentation: The case under examination pertains to a 47-year-old male inmate who has been encountering respiratory issues for a duration of four months, culminating in a diagnosis of lophomoniasis. Both blood and sputum cultures yielded negative results. Similarly, bronchoalveolar lavage tests for bacterial and fungal pathogens returned negative findings. However, bronchoalveolar lavage (BAL) results (microscopic) showed mild positive lophomoniasis targeting Lophomonas blattarum and Serum IgE=387 was relatively higher than normal limits.
Conclusion: The patient received treatment with metronidazole, leading to the resolution of all clinical complications within a span of four weeks.
