streptococcus iniae is one of the most important agents that causes high mortality and losses in rainbow trout farms in iran and the world. these bacteria can affects the consumers and people who deal with aquaculture via affected fish. so, viability of this bacterium in frozen fish and fish product can be useful for health care of consumers. a total of 90 rainbow trout, with average weight of ...

A commercial bullfrog (Rana castesbeiana) operation in south Georgia had multiple epizootics of systemic bacterial infections over a 3-year period, 1998-2000. A number of potential pathogens (Aeromonas hydrophila, Chryseobacterium (Flavobacterium) meningosepticum, Chryseobacterium (Flavobacterium) indolgenes, Edwardsiella tarda, Citrobacterfreundii, Pseudomonas spp., and (Streptococcus iniae) w...

pose potential health risks, particularly to young children. While California has reported more cases of baylisascariasis than any other state, few published studies have reported on the distribution and prevalence of this helminth in the region. In 2001, we conducted a study to determine the presence of B. procyonis in the Santa Barbara area by examining roadkill raccoons recovered by animal c...

CD96 is a membrane-bound receptor discovered in humans 1992 that mainly present natural killer cells and T derived from haematopoietic performs immune functions. Based on the sequence of obtained red seabream (Pagrus major), phylogenetic analysis with other species, infections normal fish, Streptococcus iniae sea bream iridovirus (RSIV), expression was conducted using real-time polymerase chain...

Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney o...

Nowadays, plant allelopathy, as a new type of biological algal and/or bacterial inhibition technology, has attracted extensive attention. Eight substances were isolated and identified from Jussiaea stipulacea Ohwi, five concentration gradients, well control (0, 1.25, 5, 10, 20, 50 mg/L) set, with three parallels in each group, then sampled detected at 24, 48, 72, 96 h. When the was mg/L, rate A...

The antibacterial activities of the essential oil of Eucalyptus globulus (EOEG) was determined against 7 fish pathogenic bacteria (Edwardsiella tarda, Streptococcus iniae, S. parauberis, Lactococcus garviae, Vibrio harveyi, V. ichthyoenteri and Photobacterium damselae) obtained from farmed olive flounder. The inhibitory activity was evaluated by three methods: Disc diffusion method, minimum inh...
