The presence of Aeromonas spp. in water can represent a risk for human health. Therefore, it is important to know the physiological status of these bacteria and their survival in the environment. We studied the behavior of a strain of Aeromonas hydrophila in river water, spring water, brackish water, mineral water, and chlorinated drinking water, which had different physical and chemical charac...

The most common used methods for water disinfection were chemicals like chlorine, ozonation, ultraviolet radiation, membrane processes, etc. Water disinfection using irradiation techniques is new in water treatment industry which has been developed recently. The aim of the present study was to investigate radio frequency (RF) efficiency for the inactivation of total coliform (TC), fecal colifor...

BACKGROUND This study investigated the interaction between heterotrophic bacteria and coliform, fecal coliforms, fecal streptococci bacteria in water supply networks. METHODS This study was conducted during 2013 on water supply distribution network in Aq Qala City, Golestan Province, Northern Iran and standard methods were applied for microbiological analysis. The surface method was applied t...

The microscope has been used to observe and count bacteria and somatic cells in raw milk since the early 1900’s. It has proven to be a valuable tool to the dairy industry. The milk smear procedure in use today is outlined in detail in the most recent edition of Standard Methods for the Examination of Dairy Products (i.e., SMEDP, 17 ed) and other references. For somatic cell counting, the Direct...

this study investigated of antibacterial and antioxidant activity of garlic and lemon extract (1.5 %) on the quality and shelf life of fillet, vacuum-packaged rainbow trout (oncorhynchus mykiss) during refrigerated storage. were studied by monitoring the microbiological (totalviable count, psycrotrophic), chemical (tba), ph and sensory changes for a period of 20 days in (0, 5, 10, 15 and 20). e...

The cell counting process is an important procedure for various and cell-related research applications. Many life science-related studies examine the cells to compare results concerning numbers variations. Most of related are conducted using manual methods. However, difficult, time-consuming, fallible. This study proposes automated software computer vision (CV) technology experimental investiga...

Bacteria are inactivated using a technique called photodynamic inactivation, which combines light with photosensitizer the right spectrum. The objective of this study is to ascertain e­ciency purple LEDs for photoinactivating Bacillus subtilis and Escherichia coli bacteria as well ideal LED exposure energy density. This involves exposing radiation. Two elements variation used during irradiation...

There has been a rapid awareness about multiresistant pathogens in the past 10 years and some bacteria are now resistant to most antimicrobial agents used in veterinary practice. Occurrence of multiresistant bacteria in milk from both dairy cows with high somatic cell count and clinical mastitis were analyzed. Multiple resistance of bacteria isolated from milk depends on bacteria species and is...
