Survey of bacteria associated with abdominal flap of freshwater crab (Potamon ebonyicum) at Ebonyi River basin Nigeria
Ebonyi River basin of south east Nigeria is home to the freshwater crab Potamon ebonyicum, which are consumed indiscriminately by inhabitants and tourists. Bulk of the crab meat is obtained by crabbing. A preliminary survey of pathogenic bacteria associated with vulnerable morphological part of the crab species was carried out in the basin. Bacteria were isolated from abdominal flaps of the male and female crab. A total of 53 bacterial isolates consisting 4 bacteria species such as Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aereus and Aeromonas hydrophila were recorded. Percentage composition of each bacterial species was recorded in the reproductive features of the samples. Pseudomonas aeruginosa (72%) and Staphylococcus aereus (48%) were dominant among other bacterial species in the abdominal flaps of the male and female crab. Population of E. coli (4%) was significantly low and only recorded in the abdominal flap of the male crab. The results of the study showed clearly that the reproductive feature of freshwater crab was vulnerable to pathogenic microorganisms. The edible crabs from sampled site were contaminated with bacteria species which were considered by Centre for Food Safety as hazardous to human health. Investigation on sample from other area would enhance regulation on aquaculture, handling, processing and consumption of freshwater crab.
Background: Food poisoning resulting from microbial and heavy metals pollution is commonplace. These contaminants do not only reduce the nutritional value of the food but are in many cases toxic. In this study, the proximate composition, bacterial quality and some heavy metals (Cd, Pb, Hg) concentration in three common fish species (Claria gariepinus, Heterobrachus bidorsalis and Channa obscura...متن کامل
Guilan province is located in south and south-west of the Caspian Sea. Guilan is one of the richest and the most humid region in the country due to suitable climate, ample rainfall and many water sources (springs, rivers, creeks,..),. Despite the prevailing favorable conditions, limnological studies, especially in the mountainous regions of this province are limited. A limnological study was co...متن کامل
Three haemocyte groups were identified in the freshwater crab, Potamon fluviatilis: hyalinocytes, semigranulocytes and granulocytes. The proportion of hyalinocytes was found to be 15%, that of semigranulocytes 54.25% and that of 30.75% granulocytes.متن کامل

and highly successful decapod group, their osmoregulatory capability has been studied mainly from the whole-animal perspective, and little information is available concerning their physiological mechanisms of osmotic and ionic regulation. Like the diadromous crabs that migrate between sea water and fresh water during their life cycle, the hololimnetic Brachyura also maintain large, outwardly di...متن کامل
