DipStreak CLED/MacConkey urine culture device
DIPSTREAK ® Urine Culture Device (UCD) Cat.No.BD-914 is a convenient, semi-quantitative screening culture device for inoculating and transporting urine samples as well as for detecting, enumerating and identifying specific bacteria in urine.
A unique streaking mechanism permits the isolation of single colonies even when the original bacterial population of the sample was as high as 108 organisms per milliliter.
The device is intended for use in physicians’ office laboratories and clinical laboratories as an aid in the diagnosis of urinary tract infection (UTI).
Following incubation, the number of bacterial colonies is compared with the Colony Density Chart to determine the colony forming units per ml (CFU/ml) of bacteria in the urine sample.
DIPSTREAK® UCD (Cat.No.BD-914) contains two types of media: CLED and MacConkey agar.
CLED’s electrolyte deficiency inhibits swarming of Proteus which otherwise would obscure the observation of colonies. Lactose is included in the agar to detect lactose fermenting coliform contaminants which are easily recognized by the green to yellow color change of the agar.
MACCONKEY agar is a selective and differential medium giving an excellent differentiation between coliforms and non-lactose fermenters of Gram-negative rods with inhibition of Gram-positive cocci. Most urinary tract pathogens grow on the medium, whereas most contaminants are inhibited. Differentiation of enteric microorganisms is achieved by the combination of lactose and the neutral red indicator. Colorless or pink to red colonies are produced depending upon the ability of the isolate to ferment lactose.
ChromoStreak UriSelect/MacConkey urine culture device
CHROMOSTREAK Urine Culture Device (UCD) Cat.No.BD-915 is a superior device designed to be one step ahead of all urine culturing devices

Following incubation, the number of bacterial colonies is compared with the Colony Density Chart to determine the colony forming units per ml (CFU/ml) of bacteria in the urine sample.
CHROMOSTREAK UCD contains two types of media: chromogenic agar UTIselective agar and MacConkey agar.
UTIselective agar is a non-selective chromogenic agar medium composed of a rich nutrient base for isolation and counting of all urinary tract organisms abd direct identification via demonstration of enzyme activities of the bacteria most often responsible for urinary tract infections. These include Escherichia coli, Proteus, and enterococci. The device also provides orientation for the diagnosis of the other urinary pathogens, in particular K.E.S. group Enterobacteriaceae (Klebsiellae, Enterobacter, Serratia and Citrobacter species).
MACCONKEY agar is a selective and differential medium giving an excellent differentiation between coliforms and non-lactose fermenters of Gram-negative rods with inhibition of Gram-positive cocci.

Diaslide® CLED/MacConkey urine culture device
Diaslide® Urine Culture Device (UCD) Cat.No.DS-101 is a unique, semi-quantitative culture method for the detection of urinary tract infections demonstrating bacterial counts and isolated colonies.
Diaslide® DS-101 UCD consists of a hinged plastic case containing two opposing agar media (CLED and MacConkey) separated by a sampler with a handle at one end, and two bent sampler prongs at the opposite end.
Following incubation, the number of bacterial colonies is compared with the Colony Density Chart to determine the colony forming units per ml (CFU/ml) of bacteria in the urine sample.

Industrial culture devices
NovaStreak culture device is a novel method for transport, isolation, screening and direct identification of microbial contamination in food, work surfaces and other materials of sanitary importance with no sample dilution.
Traditional standard method of detection of microbial contamination requires the sampling and further transportation of the sample to the lab, spreading of a small volume of sample onto the surface of various types of prepared culture media by trained technicians and then incubation of the media at a constant temperature and humidity for up to 5 days.
The total extra-cost of traditional standard method includes:
• expensive, skilled personnel for inoculation,
• transportation of specimens to the laboratory under special conditions (refrigeration)
• time-consuming preparing the different types of culture media.
Advantages:
• simple, rapid and handy
• immediate media inoculation at the site of collection
• perfect alternative to conventional collection and culturing of samples
• the unique sample streaking mechanism emulates the methodology of traditional Petri dish culture techniques
• sample collection and inoculation can be done by unskilled personnel
• two different agar media are attached back-to-back on a central paddle support
• discreet streaking of the sample over each agar surface
NovaStreak is successfully used in the middle-size and small pharmaceutical, food & dairy, biological, medical and agricultural industries which can afford their own laboratory but can’t buy the expensive equipment. It is suitable for companies that provide analytical and microbiological laboratory services, in scientific research, environmental control and in the different catering & food consulting agencies
