MicroRNAs (miRNAs) play a critical role in controlling tumor invasion and metastasis via regulating the expression of a variety of targets, which act as oncogenes or tumor suppressor genes. Abnormally expressed miR-625-3p has been observed in several types of human cancers. However, the molecular mechanisms of miR-625-3p-mediated tumorigenesis are largely elusive. Therefore, the aim of this stu...

AIMS To study the occurrence and spatial distribution of Shiga toxin-producing Escherichia coli (STEC) O157 in calves less than 1-week-old (bobby calves) born on dairy farms in the North Island of New Zealand, and to determine the association of concentration of IgG in serum, carcass weight, gender and breed with occurrence of E. coli O157 in these calves. METHODS In total, 309 recto-anal muc...

OBJECTIVE To assess the microbiological safety of kale (Brassica oleracea Acephala) produced from farms and those sold at the markets with special focus on coliforms, E.coli and Salmonella. DESIGN A cross sectional study. SETTING Peri-Urban farms (in Athi River, Ngong and Wangige), wet markets (in Kawangware, Kangemi and Githurai), supermarkets and high-end specialty store both within Nairo...

Sows and pigs from 10 commercial swine farms were sampled to determine patterns of resistance of fecal Escherichia coli to five commonly used antibiotics. Before testing, farms were categorized as high or low antibiotic use based on interviews with the respective producers. On each farm, fecal swabs were obtained from five sows at 7 d postpartum and from five pigs from each sow at 7, 35, and 63...

Samples from cattle, other domestic and wild animals, flies, feeds, and water-troughs were collected from 12 cattle farms and tested for Escherichia coli O157. E. coli O157 was isolated from bovine fecal samples on all 12 farms with a within herd prevalence ranging from 1.1% to 6.1%. E. coli O157 was also found in 1 of 90 (1.1%) equine fecal samples, 2 of 65 (3.1%) canine fecal samples, 1 of 20...

The increase of extended- spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) in humans and in food-producing animals is of public health concern. The latter could contribute to spreading of these bacteria or their resistance genes to humans. Several studies have reported the isolation of third generation cephalosporin resistant bacteria in livestock animals. However, the number of sampl...

The prevalence of the hepatitis E virus (HEV) infection in pigs in Northern Italy was serologically examined. The survey was carried out on 39 farms: 17 farrow-to-feeder, 10 farrow-to-finish, and 12 fattening enterprises. There were 1,422 sera that were tested using commercial indirect ELISA. This method originally developed for testing human sera was adapted for the analysis of pig sera. All f...

Ethiopia has the largest livestock population in Africa but the contribution of this resource to the economy is limited and yet the country is in poverty. Dairy development has a big role for the contribution of income generation and employment. Demand for dairy products seems to exceed supply in the country in general and the study area in particular. Hence, the situation of dairy production a...

Anticoccidial effects of green tea (GT)-based diets were evaluated in chickens following oral infection with Eimeria maxima an ubiquitous intestinal parasite of poultry that impairs the growth and feed efficiency of infected birds. Five-week-old chickens were assigned to four groups (GT 0.5%, GT 2.0%, untreated/infected and non-infected control) and each group consisted of 15 chickens. Chickens...

A 37-d laying hen experiment was performed to determine the effect of Diamond V XPC(LS) (XPC(LS), Diamond V Mills, Cedar Rapids, IA) during a subclinical Eimeria maxima infection on intestinal health and productivity. Two hundred and sixteen 18-wk-old Brown Nick laying hens were allocated to 24 litter pens based on a weight class system (9 hens/pen). The trial was carried out as a 2 × 2 factori...
