brucellosis is an infectious disease with high impact on innate immune responses which is induced partly by its dna. in the present study the potential differences of wild type and patients isolates versus attenuated vaccine strains in terms of cytokines, ros and no induction on murine splenocytes and peritoneal macrophages were investigated. this panel varied in base composition and included d...

noise is considered as one of the most severe sources of environmental and work place constraints. noise effects on immune function, hormonal levels, cardiovascular and respiratory systems are well known. the aim of the study is to evaluate the effects of traffic noise on basal and stimulated gastric acid secretion. 48 healthy rats were divided into five traffic noise exposures (1, 7, 14, 21, 2...

A study was carried out to evaluate the secondary sexual characteristics of four strains of cocks, comprising of two (2) exotics; Bovan Nera Black (BNB) and Isa Brown (ISB), one (1) improved local strain, Shika Brown (SB) and one (1) unimproved local strain, normal feathered cock (NFC). A total of 64 birds (16 for each strain) at 36, 38, 40 and 42 weeks were used for the study. The result indic...

Infectious bursal disease (IBD) is a highly contagious disease of chickens caused by the infectious bursal disease virus (IBDV). This study was conducted to characterize three IBDV strains from Iran. A reverse transcriptase-polymerase chain reaction (RT-PCR) procedure was used to amplify a 715-bp fragment of the VP1 gene from IBDV strains. Amplified VP1 fragments of the three Iranian IBDV strai...

Anthracnose is a general term for sunken lesions and blights on stems, leaves and fruits which causes economic damage to agricultural products. This study, conducted to identify Colletotrichum species associated with anthracnose symptoms on some plants in Khuzestan province (Iran) using morphological and molecular methods. During 2016–17, 40 leaf and fruit samples showing anthracnose symptoms (...

This research investigated the feasibility of using three strains Lactobacillus sp. viz. AM11, AM13, and AM14 previously isolated from dairy products to be used as probiotics in fish diet for phytase production. The bacteria grown in oxygenated media, bile salt, acid and supernatant of digestive tract  were examined for their antibiotic resistance and non-pathogenicity for using in fish feed. R...

Previous studies had shown that sub-inhibitory concentrations of silver sulphadiazine (AgSD) stimulated the production of Toxic Shock Syndrome Toxin-1 in certain strains (responder strains) of Staphylococcus aureus and that protease production was also affected. No changes were detected in other strains (non-responders). Extracellular proteins from eleven responder and non-responder strains gro...
