experimental pathogenicity of shrimp, penaeus vannamei exposed to monodon baculovirus (mbv)

چکیده
the objective of our study was to explain the histopathological changes of monodon baculovirus (mbv) in hepatopancreas and midgut tissues of the cultured penaeus vannamei. five-hundred and forty juvenile of p. vannamei with average size of 7.99±0.54 g and 3600 post larvae 10-15 were distributed to 18 glass aquariums (50×50×60cm) with 100l well aerated water per each aquarium as water borne mbv (group a) and food borne mbv (group b) and one control group (c), in triplicates. also, 3600 post larvae were dedicated for water borne exposure (d) based on one time immersion exposure in 24 h without water exchange and the untreated group was studied as control in triplicates. the specific pathological sign of mbv was observed as a multiple intranuclear eosinophilic occlusion bodies (obs) in hepatopancreas and midgut tissues. our result indicates that the severity of the mbv infection is more considerable in post larvae than juvenile stage and confirms that mbv can be an invasive pathogen for shrimp culture industry in iran.

متن کاملStrain Variations in Monodon Baculovirus (mbv) Infecting Penaeus Monodon (tiger Shrimp) in India
Viral diseases are the most serious problem in shrimp culture as they result in severe production and economic losses. Monodon baculovirus (MBV) is a member of nucleopolyhedrosis virus (NPV) group that infect penaeid shrimps. Polymerase chain reaction (PCR) assays have been reported for specific and accurate detection of MBV. As variations in the strains of MBV would greatly affect the detectio...
متن کاملIdentification of Penaeus monodon Baculovirus (MBV)in cultured Penaeus semisulcatus in Islamic Republic of Iran
Shrimp aquaculture has a short history in I.R Iran. Farmed shrimp production grew slowly from 1992 until 2000 when a number of large farms started to produce. In 2000, the total production was about 4,500 MT and it was estimated that more than 7,000 MT would be produce by the year 2001. From August 1997 to March 1998, two thousand samples of cultured Penaeus semisulcatus postlarvae and subadult...

متن کاملDuplex real-time PCR for detection and quantification of monodon baculovirus (MBV) and hepatopancreatic parvovirus (HPV) in Penaeus monodon.
We describe a duplex real-time PCR assay using TaqMan probes for the simultaneous detection of monodon baculovirus (MBV) and hepatopancreatic parvovirus (HPV). Both MBV and HPV are shrimp enteric viruses that infect intestinal and hepatopancreatic epithelial cells. Both viruses can cause significant mortalities and depressed growth in infected larval, postlarval, and early juvenile stages of sh...
