Mycoplasma gallisepticum and Mycoplasma synoviae are the causative agents of avian mycoplasmosis in commercial poultry. Among the available tools, polymerase chain reaction (PCR) and culture are confirmatory tools for the diagnosis of mycoplasmosis after the initial serological screening of suspected birds. Overall, 181 samples were analyzed, 152 (84%) and 103 (57%) of which were found positive...

influenza a viruses possesses two virion surface glycoproteins including haemagglutinin (ha) and neuraminidase (na). the na plays an important role in viral replication and promotes virus release from infected cells and facilitates virus spread throughout the body. to find out any genomic changes that might be occurred on na gene of avian influenza circulating viruses, we have genetically analy...

avian influenza is one of the most important diseases in avian industry, which also threats human population. thus, vaccination is necessary for controlling this viral disease. in this study, killed vaccine of avian influenza subtype h9n2 and formalin solution (for virus inactivation) were used. it is necessary to study the effect of different factors such as formalin concentration, as well as ...

This study was conducted to molecularly detect avian adenoviruses in broiler flocks showing liver lesions and respiratory syndrome in northeast Iran. In total, 60 tissue samples were collected from broiler farms with liver lesions, respiratory syndrome and also from clinically healthy flocks. Six samples were positive; however, three samples were selected for molecular studies. PCR products wer...

Schistosomes are blood flukes that parasitize the venous system of a wide range of animals including birds, cattle and primates. There are seven human pathogenic species of which the, most prevalent are S. hematobium, found mainly in Africa, S. mansoni found in Latin America as well as Africa, and S. japonicum, endemic in China and the Far East. According to WHO estimates, some 700 million inha...

In the town of Bakel, the French scientist Le Dantec encountered 20 patients showing symptoms of “vesical Schistosomiasis” in 1908. This represents the first record of schistosomiasis cases in Senegal [1]. In line with the country’s great diversity in aquatic habitat within Senegal, at least five species of snails are known to act as intermediate hosts for human infective schistosomes: Bulinus ...
