Lactic acid bacteria, including lactobacilli, enterococci, leuconostoc and weissella species isolated from Iranian traditional fermented camel milk (Chal) were assessed for the incidence of virulence determinants (gelE, efaAfm, efaAfs, ace, espfs, cylM, cylA and cylB), sensitivity to various antibiotics and virulence phenotypes. The incidence of virulence genes was determined by polymerase cha...

The lactic acid bacteria Lactococcus lactis and Streptococcus thermophilus play a crucial role in the manufacture of dairy products such as cheese, buttermilk and yogurt. In this contribution, different metabolic engineering strategies are described aimed at improvement of the quality of the fermented dairy product. By increased production of diacetyl or acetaldehyde, the particular flavour of ...

This study evaluated the presence of biogenic amines in fermented cow's and goat's milks containing probiotic bacteria, during the first 10 days of chilled storage (4 ± 2°C), when the probiotic strains are most viable. The overall acceptance of both fermented milks, produced using the same starter culture and probiotics, was tested. In both products, the initially high levels of tyramine (560 m...

BACKGROUND Human brucellosis is common in southern Israel among the semi-nomadic Bedouin, a population that consumes unpasteurized dairy products. Though camel milk ingestion is a known mechanism for brucellosis acquisition, only a few reports of sporadic cases have been published in the medical literature. OBJECTIVES To describe a local brucellosis outbreak in 15 extended Bedouin family memb...

Modifications in gastrointestinal parameters, intestinal colonization and tolerance are some of the main goals claimed for probiotics. However, although healthy people are the common target for these new functional food products, the number of clinical trials analysing the effects of probiotics in gastrointestinal parameters of healthy subjects is very scarce. A randomized, double blind, placeb...

The unhygienic handling practices in traditional camel milk production and in the informal camel milk trade represent serious obstacles for the introduction of modern dairy processing and marketing. The successful adaptation of pastoral subsistence production to the needs of an improved camel milk production and marketing system will depend, to a large extent, on safeguarding the milk quality a...

selenium (se) is considered as an essential element for human body. selenized probiotic fermented milk drink (doogh) as a functional beverage to increase se available in body. the predominate sugar, protein and mineral ion of iranian yoghurt drink (doogh) are lactose, casein and calcium, respectively. different levels of  selenium (2.5 – 3- 3,5-  4 and 4.5) is prepared and its suitability based...

Lactobacillus helveticus BGRA43 is a human intestinal isolate showing antimicrobial activity, amongst others, against Yersinia enterocolitica, Shigella sonnei, Shigella flexneri, and Streptococcus pneumoniae. BGRA43 produces PrtH proteinase with proteolytic activity on both casein and β-lactoglobulin (BLG). BGRA43 is able to reduce the allergenicity of BLG. Bioactive peptides released in BGRA43...

INTRODUCTION Antibiotic-associated diarrhea (AAD) is common and frequently more severe in hospitalized elderly adults. It can lead to increased use of healthcare resources. We estimated the cost-effectiveness of a fermented milk (FM) with probiotic in preventing AAD and in particular Clostridium difficile-associated diarrhea (CDAD). METHODS Clinical effectiveness data and cost information wer...
