In this study, the pathogenicity of A/Ch/It/5093/1999 H7N1 which had been isolated from chicken during the outbreak in Italy was assessed in chicken by experimental infection virus. Ten SPF chickens of four week-old were inoculated with this virus, and five chickens were inoculated with uninfected allantoic fluid. For determination of virus shedding, oropharyngeal and cloacal swabs were taken f...
conclusions this epidemiological study indicated different rates and transmission risks for these viruses. hcv was the most contagious viral infection and htlv-i was the weakest in the prisoners. apart from kshv infection which its prevalence was as twice as in the general population, the prevalence of hbv and htlv-i in prisoners was nearly in ranges of the general population. background prison...
Background and Aims: Herpes simplex virus type 1 (HSV1) remains a potentially serious health problem world wide. All infected people, including asymptomatic ones, are potential sources for virus transmission. Virus envelope contains at least 13 glycoproteins, which glycoprotein D is the major target of immune responses. The aim of this study was development of a specific method that is a more...
Background: The H9N2 subtype of the influenza virus, which is endemic in many regions of Iran, is considered as a candidate for future pandemics. In the present study, excretion time of the Iranian endemic influenza virus (H9N2 subtype) from the feces and pharyngeal secretions of laying chicken breeds was evaluated. Methods: This experimental study conducted at the Diagnostic Laboratory Scienc...
background: due to their similar routes of transmission, human immunodeficiency virus (hiv) and hepatitis b virus (hbv) co-infection occurs considerably. hbv infection progresses more rapidly in hiv-infected patients. therefore, hbv vaccination of all non-immune hiv infected patients is recommended. on the other hand, hiv-infected subjects have suboptimal responses to hbv vaccine. in this study...
acyclovir (9-[2-hydroxyethoxymethyl] guanine) is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. acycloviris converted to the monophosphate by thymidine kinase the virus-specific form of this enzyme and is subsequently converted to the triphosphate by the host cell kinase. acyclovir triphosphate inhibits viral dna-polymerase terminating the chain and...
objectives: patients with hepatitis c virus infection are at high risk of getting hepatitis a virus. hepatitis a virus is an important widespread virus that usually causes more severe medical consequences in patients with chronic liver disease. the purpose of this study was to evaluate prevalence of hepatitis a virus antibody in patients with chronic hcv in isfahan province, iran. methods: a cr...
ulcerative colitis (uc) is one type of inflammatory bowel disease (ibd). herpes viruses have been suggested as possible etiological agents of uc and crohn’s disease (cd). the aim of this study was to investigate the prevalence of herpes simplex virus (hsv), cytomegalovirus (cmv) and epstein-barr virus (ebv) in patients with uc in comparison with healthy subjects by using pcr technique. in this ...
گیاه یونجه از جمله مهمترین نباتات علوفه ای محسوب می گردد. سطح زیر کشت یونجه در سال 1388 در استان آذربایجان غربی حدود یکصد هزار هکتار با تولید بیش از نیم میلیون تن علوفه بوده است. بیماریهای ویروسی از جمله مهمترین محدودیتها در افزایش عملکرد این محصول محسوب می گردند. در طول فصل زراعی 1388 ، طی بازدید از مزارع یونجه استان آذربایجان غربی به منظور شناسایی بیماریهای ویروسی مهم یونجه، نمونه ها ی آل...
results of 351 patients, 76 patients (group 1) had a strong positive result for salivary occult blood test and 275 patients (group 2) had weak positive or negative test results. significant factors between the groups were obesity, level of ast, alt, ldh, alp, alb, d.bil, t.cho, afp, platelets (plt), iri, homa-ir, current interferon (ifn) treatment and the daily frequency of tooth brushing. betw...
