The olfactory receptor organs and their primary centers are classified into several types. The receptor organs are divided into fish-type olfactory epithelium (OE), mammal-type OE, middle chamber epithelium (MCE), lower chamber epithelium (LCE), recess epithelium, septal olfactory organ of Masera (SO), mammal-type vomeronasal organ (VNO) and snake-type VNO. The fish-type OE is observed in flatf...
In this study, mitochondrial DNA analysis using 16S ribosomal DNA (rDNA) was performed to investigate the phylogeny relationship of Trichiurus lepturus in the Persian Gulf compared to the other investigated area. The amplification of 16S rDNA resulted in a product of 600 bp in all samples. The results showed that the isolated strain belongs to T. lepturus showing 42 divergence sites among the s...
The p51 gene that encodes the major antigenic 51-kDa protein in Neorickettsia risticii was identified in strains of Neorickettsia sennetsu and the Stellantchasmus falcatus agent but not in Neorickettsia helminthoeca, suggesting that p51-based diagnosis would be useful to distinguish among them. groESL sequencing results delineated the phylogenic relationships among Neorickettsia spp.
A disease outbreak with dengue-like symptoms was reported in Guangdong Province, China, in October 2010. Testing results confirmed that the pathogen causing the outbreak was chikungunya virus. Phylogenic analysis indicated that this virus was a member of the Indian Ocean clade of the East/Center/South African subgroup of chikungunya virus.
Chikungunya fever is reported in India after 32 years. Immunoglobulin M antibodies and virus isolation confirmed the cause. Phylogenic analysis based on partial sequences of NS4 and E1 genes showed that all earlier isolates (1963-1973) were Asian genotype, whereas the current and Yawat (2000) isolates were African genotype.
background and objective: biodeterioration is an irreversible damage that is caused by colonization of microorganisms on the surface of different materials. among all microorganisms, fungi play an important role in deterioration of materials. fungi can colonize on stone surfaces and by secreting different enzymes, organic and inorganic acids and pigments, can cause bio-weathering and changing n...
Investigation of Infectious Laryngotracheitis Virus in Broiler Flocks in Sulaymaniyah Province, Iraq

 Infectious laryngotracheitis (ILT) is an acute contagious upper respiratory tract infection of chickens and other birds, caused by Gallid herpesvirus1 (GaHV-1), which has economic importance in the poultry industry. There was no scientific data about incidence disease broiler farms Sulaymaniyah province/Iraq. Therefore, this study aimed to investigate ILTV that region. Clinically inf...
