Preliminary study of molecular identification of Mycobacterium bovis from cow's milk in Lorestan (Iran).

Bovine tuberculosis is one of the most important common infectious diseases between humans and livestock. Cow's milk can be investigated as one of the transmission reservoirs of the disease. Our study was conducted to investigate the presence of Mycobacterium bovis (M.

Genetic diversity of isolates from sheep and goat milk in Iran.

The genetic diversity of strains has not been fully understood. To investigate this, the genetic characteristics of 64 isolates of from sheep and goats' milk were studied using random fragment length polymorphism (RFLP) and multiple locus variable-number tandem repeat analysis (MLVA-16) methods developed in Orsay, France (MLVA-16). The RFLP analysis revealed that all 64 isolates were of biovar one.

Investigation of the Proportion of and in Sheep and Goat Milk.

Despite the implementation of brucellosis eradication programs in Iran, this disease is still endemic and highly prevalent among ruminants in this country. The infection of small ruminants with may play a significant role in the continuation of brucellosis among the herds of ruminants. This study investigated the proportion of and in 150 samples of sheep and goat's raw milk which were obtained from Lorestan and Hamadan provinces in the western part of Iran using the PCR method.

Short Communication: Prevalence of in Raw Milk of Healthy Sheep and Goats.

, one of the most important bacterial pathogens transmitted through milk, causes listeriosis in humans and animals. This study aimed to investigate the prevalence of in raw milk of healthy sheep and goats in the west of Iran (Lorestan Province) by touchdown PCR (TD-PCR). spp.

Use of touch-down polymerase chain reaction to enhance the sensitivity of detection in raw milk.

Brucellosis is a highly contagious bacterial zoonotic infectious disease severely affecting the public health and economic features of endemic and non-endemic countries. The present study assessed the potentials of using the touch-down polymerase chain reaction (TD-PCR) compared to the conventional PCR and culture methods in order to detect in raw milk samples of 55 sheep and 45 goats through deriving the primers from the element of the genome. In addition, nine isolates of were identified using the culture method.

Antagonistic effect of isolated probiotic bacteria from natural sources against intestinal pathotypes.

Background: Probiotics are live microorganisms which are beneficial bacteria that are normal flora of the digestive system which, in determined amounts, show beneficial effects on host health, and can balance gastrointestinal microflora. Digestive tract diseases such as diarrhea are one of the major causes of child mortality in developing countries. Different pathotypes of cause diarrhea that affects children, therefore reduction of these colonization strains in humans or animals can decline gastrointestinal disorders such as diarrhea.
