BACKGROUND The main cause of bovine tuberculosis (bTB) is believed to be Mycobacterium bovis (M. bovis). Nontuberculosis mycobacteria (NTM) are neglected but opportunistic pathogens and obstacles for bTB diagnosis. This study aimed to isolate and characterize the mycobacteria organisms involved in causing TB-like lesions in cattle in northwestern Ethiopia. RESULTS A total of 2846 carcasses of...

The aim of the present study was to determine the levels of cadmium in the muscle, liver and kidney of cattle from Isfahan and to compare the results with those reported by other countries and with the maximum acceptable levels for human consumption. Samples of muscle, liver and kidney from 60 animals aged 1–10- year-old were collected from the carcasses slaughtered at Isfahan abattoir. Samples...

This study was carried out to determine the prevalence and type of renal lesions in cattle that were slaughtered at the Ghaem (Shahriar) and Ziaran (Ghazvin) abattoirs. A total number of 405 clinically normal cattle were randomly selected and renal samples were taken for histopathological study. The cattle were divided into two groups according to sex, and female groups were divided into two ag...

Many immune down-regulatory molecules have been isolated from parasites, including cystatin (cystain protease inhibitor). In a previous study, we isolated and characterized Type I cystatin (CsStefin-1) of the liver fluke, Clonorchis sinensis. To investigate whether the CsStefin-1 might be a new host immune modulator, we induced intestinal inflammation in mice by dextran sodium sulfate (DSS) and...

Background and purpose: Fascioliasis is one of the zoonotic diseases in the world that has public health and economic perspectives. The aim of this study was to investigate the prevalence of Fascioliasis in slaughtered cattle in the industrial slaughterhouse of Arak, Iran (2007-2010). Materials and Methods: This study sample was consisted of 648994 head of cattle including 292797 sheep, 81012 ...

In cirrhosis, arterial vasodilation and the associated hemodynamic disturbances are most prominent in the mesenteric circulation, and its severity has been linked to bacterial translocation (BT) and endotoxemia. Synthesis of nitric oxide (NO), the main vasodilator implicated, is dependent on the essential cofactor tetrahydrobiopterin (BH(4)). The key enzyme involved in BH(4) synthesis is GTP-cy...
