Studies on water quality and fish diversity of Sadatpur lake in Ahmednagar district Maharashtra

The present study deals with the water quality and ichthyofauna of Sadatpur lake. Monthly changes in water quality parameters such as temperature, pH, dissolved oxygen (DO), total alkalinity, chlorides, sulphates, phosphates and nitrites have been studied for a period of one year beginning from January 2005 and were investigated to assess the suitability of this lake for fish and fisheries practices. All the physico-chemical parameters determined, revealed that the fluctuations in water temperature, pH, dissolved oxygen, alkalinity and nitrites, were within the desirable limits. On the other hand, chloride and sulphate were lower whereas phosphate was higher than the desirable limits. Altogether 24 fish species belonging to 17 genera and 2 orders were found to be present in the lake. Among fish species family Cyprinidae dominated the lake. The lake subsistence fishery served the need of local fishermen community

International nosocomial infection control consortium (INICC) report, data summary of 36 countries, for 2004-2009

The results of a surveillance study conducted by the International Nosocomial Infection Control Consortium (INICC) from January 2004 through December 2009 in 422 intensive care units (ICUs) of 36 countries in Latin America, Asia, Africa, and Europe are reported. During the 6-year study period, using Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infections, we gathered prospective data from 313,008 patients hospitalized in the consortium's ICUs for an aggregate of 2,194,897 ICU bed-days. Despite the fact that the use of devices in the developing countries' ICUs was remarkably similar to that reported in US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were significantly higher in the ICUs of the INICC hospitals; the pooled rate of central line-associated bloodstream infection in the INICC ICUs of 6.8 per 1,000 central line-days was more than 3-fold higher than the 2.0 per 1,000 central line-days reported in comparable US ICUs. The overall rate of ventilator-associated pneumonia also was far higher (15.8 vs 3.3 per 1,000 ventilator-days), as was the rate of catheter-associated urinary tract infection (6.3 vs. 3.3 per 1,000 catheter-days). Notably, the frequencies of resistance of Pseudomonas aeruginosa isolates to imipenem (47.2% vs 23.0%), Klebsiella pneumoniae isolates to ceftazidime (76.3% vs 27.1%), Escherichia coli isolates to ceftazidime (66.7% vs 8.1%), Staphylococcus aureus isolates to methicillin (84.4% vs 56.8%), were also higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 7.3% (for catheter-associated urinary tract infection) to 15.2% (for ventilator-associated pneumonia).

WATER QUALITY AND FISH DIVERSITY OF SADATPUR LAKE IN RELATION TO PISCICULTURE, AHMEDNAGAR, MAHARASHTRA

The present study deals with the water quality and ichthyofauna of Sadatpur lake. Monthly changes in water quality parameters viz., temperature, pH, dissolved oxygen (DO), total alkalinity, chlorides, sulphate, phosphate and nitrite have been studied for a period of one year beginning from January 2005 and were investigated to assess the suitability of this lake for fish and fisheries practices. All the physico-chemical parameters determined, revealed that the fluctuations in water temperature, pH, dissolved oxygen, alkalinity and nitrite were with in the desirable limits. On the other hand, chloride and Sulphate were lower where as phosphate was higher than the desirable limits. Altogether 24 fish species belonging to 17 genera and 2 orders were found to be present in the lake. Among fish species family Cyprinidae dominated the lake. The lake subsistence fishery and served the need of local fishermen community

STUDIES ON WATER QUALITY OF KELEWADI LAKE IN RELATION TO PISCICULTURE, MAHARASHTRA

Changes in water quality parameters (physico-chemical) of a rain fed Kelewadi lake at Kelewadi village, near Bota, Sangamner taluka, Ahmednagar district were investigated to assess the suitability of this lake for pisciculture. Several parameters viz., temperature, dissolved oxygen (DO), pH, total alkalinity, chloride, hardness, calcium, magnesium, nitrite and phosphate have been studied for a period of one year beginning from February 2008 to January 2009. All the physico-chemical parameters determined, revealed that the fluctuations in water temperature, dissolved oxygen, pH, total alkalinity, hardness and nitrite in all the seasons and magnesium during summer and phosphate during post-monsoon to summer were with in the desirable limits for fish and fisheries practices. However, low level of chloride and calcium in all the seasons and magnesium in monsoon to winter and high level of phosphate during monsoon were recorded. These parameters need to be modifying in order to favour fish culture

ELECTROPHORETIC PROTEIN PROFILES OF DIFFERENT TISSUES OF LAMELLIDENS MARGINALIS (LAMARCK) FROM KAGDIPURA SWAMP

EIectrophoretc protein pattern of different tissues viz, gonad, hepatopancreas, foot, mantle, gill, anterior adductor muscle, posterior adductor muscle and siphon of Lamellidens marginalis from Kagdipura swamp was studied during summer season (2001). Study revealed that, protein bands were found to be maximum (5) in the foot while minimum (2) in the mantle. Among the different tissues, total 6 different protein bands were observed, ranged from 0.0408 REM and 86,377 Da to 0.9592 REM and 10,943 Da. It was pointed out that protein band Ill with REM 0.3673 and MW 41,440 Da was occurred only in gills. It was found that fast moving fractions were occurred in all the tissues, slow moving protein fractions were absent in the gills whereas intermediate fractions were absent in case of the anteriorand posterior adductor muscles, mantle and gonad. It was pointed out that the proteins of specific molecular weight are present in specific physiological important tissues and decrêase in the number of protein fractions and simplifkation of molecular structure might be due to functional requirements of the tissue
