Microbial contamination is the most important reason for losses in both scientific and commercial micropropagation systems. Microbial contaminants can be introduced both with the explants used to initiate plant tissue cultures and at every stage of the tissue culture process in the laboratory [3, 4, 33]. However, it is often difficult to determine the exact source or sources of contamination from a visible assessment of the contaminated cultures.

This portion of Part I addresses the basic principles and methods of sampling environmental surfaces and other environmental sources for microorganisms.

Prevention and Detection of Mycoplasma Contamination in Cell Culture

Inside the body, cells are protected by the highly evolved and sophisticated immune system. We must therefore protect them with careful aseptic techniques to prevent their contamination from microorganisms that are present all around us, including inside the laboratory. Various types of contamination exist: for example, cells can become contaminated with bacteria, mycoplasma, or mold. Others will be noticeable and will force you to interrupt your experiments - which wastes time, energy and money.

One of the main problems in cell culture is mycoplasma infection. It can extensively affect cell physiology and metabolism. As the applications of cell culture increase in research, industrial production and cell therapy, more concerns about mycoplasma contamination and detection will arise. This review will provide valuable information about: 1. Awareness about the sources of mycoplasma and pursuing aseptic techniques in cell culture along with reliable detection methods of mycoplasma contamination can provide an appropriate situation to prevent mycoplasma contamination in cell culture.

Contaminations in the laboratory can be a nightmare for scientists, especially as they can spread from one sample to all others present in the same incubator or hood.

The transmission of infectious diseases via contaminated water continues to be a risk to public health in the United States and throughout the rest of the. Source and finished drinking waters are vulnerable to microbial pathogen contamination from a variety of sources of human and animal fecal wastes and from the introduction and proliferation of nonfecal pathogenic microbes. Throughout most of the modem history of drinking water supply, concerns about pathogenic microbes have focused on enteric bacteria of human fecal origin. These concerns led to the development of criteria and standards for bacteriological quality intended to protect against excessive risks from enteric bacterial pathogens such as Salmonella typhi and other nontyphoid Salmonella spp. The infectious disease risks in drinking water supplies from enteric viruses such as hepatitis A virus , enteric parasites such as Entamoeba histolytica and Giardia lamblia , and nonfecal bacterial pathogens such as Legionella spp.

Erukhimovitch, M. Huleihil, M. Fourier transform infrared microspectroscopy FTIR-M can detect small molecular changes in cells and therefore was previously applied for the identification of different biological samples. In the present study, FTIR spectroscopy was used for the identification and discrimination of Vero cells infected with herpes viruses or contaminated with bacteria or fungi in cell culture. Vero cells in culture were infected herpes simplex virus type 1 HSV-1 or contaminated with E. Specific different spectral changes were observed according to the infecting or contaminating agent.

Куда она могла уйти. Неужели уехала без меня в Стоун-Мэнор. - Эй! - услышал он за спиной сердитый женский голос и чуть не подпрыгнул от неожиданности. - Я… я… прошу прощения, - заикаясь, сказал Беккер и застегнул молнию на брюках. Повернувшись, он увидел вошедшую в туалет девушку. Молоденькая, изысканной внешности, ну прямо сошла со страниц журнала Севентин. Довольно консервативные брюки в клетку, белая блузка без рукавов.


Bacterial and fungal contaminants are detected by direct culture under conditions that specifically favor bacteria, mycelia, and yeast (see Basic.


How to minimize contamination risk and protect your cultures

На переднем плане возникли деревья. Парк был пуст. - Фильтр Х-одиннадцать уничтожен, - сообщил техник.

Свет в бывшем гимнастическом зале выключили. Пьер Клушар спал глубоким сном и не видел склонившегося над ним человека. Игла похищенного у медсестры шприца блеснула в темноте и погрузилась в вену чуть выше запястья Клушара. Шприц был наполнен тридцатью кубиками моющего средства, взятого с тележки уборщицы.

Клушар закрыл глаза, силы покинули. Он едва дышал.

    There is nothing more tragic than walking into your tissue culture room only to find a researcher curled up on the floor, clasping a flask, and wailing that their cells have been contaminated.
