Clostridium perfringens type A beta2 toxin in elephant (Elephas maximus indicus) and pygmy hog (Sus salvanius) with haemorrhagic enteritis in Assam, India
This paper reported the investigation of haemorrhagic enteritis in female elephant (Elephas maximus indicus) and pygmy hog (Sus salvanius) at the Assam State Zoo, Guwahati, Assam, India. An eight year old female elephant and two and half year old female pygmy hog developed haemorrhagic enteritis of unknown cause maintained at the zoo died within four days. Bacteriological investigation revealed that the causative...

Drynaria quercifolia (L.) J.Sm: A potential resource for antibacterial activity
Six different organic solvents such as ethanol, methanol, petroleum ether, hexane, benzene and chloroform were used to extract the bioactive compounds from the rhizome of Drynaria quercifolia to screen the antibacterial activity against infectious disease causing bacterial pathogens such as Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhi, Salmonella...

In vitro detection and characterization of bacteriocin-like inhibitory activity of lactic acid bacteria (LAB) isolated from Senegalese local food products
The prevalence of lactic acid bacteria (LAB) in Senegalese local food products was determined to be 109 CFU/g in millet flour and milk products, and 103CFU/g in seafood products. These food products are generally preserved by spontaneous fermentation (without addition of starters). Of 220 lactic acid bacteria strains randomly selected from such products, 12 isolates capable of producing bacteriocin-like substances...

Biodegradation of hydrocarbons in untreated produce water using pure fungal cultures
Biodegradation studies of hydrocarbons in untreated produce water from an oil production facility in Nigeria were undertaken over a period of time using pure fungal cultures (Penicillium sp. and Aspergillus niger). The rate of reduction in some petroleum hydrocarbon fractions, such as n-alkanes, aromatics, nitrogen, sulfur and oxygen (NSO)-containing compounds and polycyclic aromatic...

Detection and identification of groundwater bacteria in Sebha City, Libya
Drinking water systems supplied by untreated groundwater were examined to determine whether coliform or heterotrophic plate count bacteria are capable of growing. Filterable bacteria were present in 42% of the 46 groundwater sources examined by using nonselective media (R2A and full strength m-HPC agars). Pseudomonads were the most frequently identified group of filterable bacteria...
