statement of the problem: dental caries is the most common disease of childhood. using probiotics has recently been introduced to reduce the incidence of dental caries.it consists of live microbial food supplements that beneficially affect the host, and hence are considered an alternative way to eradicate the infections. purpose: the aim of this study is to evaluate the effect of consumption of...

introduction group b streptococcus is the main reason of neonatal infection in developed countries and causes a widespread clinical indications. in developing countries such as iran, its rate of appearance is not determined. with regard to colonization and the relative high epithelia of group b streptococcus, it is likely that the incidence of group b streptococcus in neonatal sepsis is so high...

Background and Aims: Leishmaniasis is an intracellular protozoan- parasitic disease, the common vector of transmission. Both zoonotic and anthroponotic cutaneous leishmaniasis (CL) are endemic in different foci. With regard to the cutaneous form, 1.0-1.5 million cases were reported annually with 90% of the cases.

this research aimed to investigate the viability of probiotic bacteria ( lactobacillus acidophilus la-5 and bifidobacterium lactis bb-12) and yogurt bacteria ( streptococcus thermophilus and lactobacillus delbrueckii ssp. bulgaricus ) in yogurt during the fermentation, immediately after fermentation and during refrigerated storage (21 d, 4˚c). also the biochemical characteristics of milk as aff...

Different genera and species of gram-positive, catalase-negative cocci are pathogenic to fish. The numbers of infections caused by these microorganisms have increased during the last decade, and such infections are responsible for significant economic losses in the fish farm industry (9). Identification of these bacteria can be difficult when using conventional microbiological criteria, and the...

conclusions the emergence of streptococcus pneumoniae strains with multiple resistance needs permanent monitoring of antibiotic susceptibility patterns of clinical isolates. we have found that ceftazidime is not a suitable drug for choosing the treatment of pneumococcal infections. results the study showed that three strains (6%) and six strains (12%) indicated intermediate resistance and compl...
