during the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. in this study, the antibacterial activity of methanolic extract of t. pubescens (rich i...

The detection of pathogenic microorganisms in aquatic environments is extremely relevant in terms of public health. As these laboratorial methodologies are usually difficult, expensive and time-consuming, they are frequently replaced by the assessment of fecal indicator bacteria, such as Escherichia coli. This study aimed to assess the presence of E. coli in fecal samples from Neotropical otter...

gum of butea monosperma is used to treat microbial and fungal infections in folk medicine. to validate this use, the in- vitro antimicrobial activity of petroleum ether and alcoholic extract of butea monosperma gum was evaluated against various microbial strains such as staphylococcus aureus, bacillus subtilis, bacillus cereus, salmonella typhimurium , pseudomonas aeuriogenosa, escherichia coli...

OBJECTIVE To assess the prevalence of faecal coliform bacteria and multiple drug resistance among Escherichia coli and Salmonella serotypes from Vembanadu Lake. STUDY DESIGN Systematic microbiological testing. METHODS Monthly collection of water samples were made from ten stations on the southern and northern parts of a salt water regulator constructed in Vembanadu Lake in order to prevent ...

background : cockroaches mechanically spread pathogenic agents, however, little is known about their gut microbiota. identification of midgut microbial community helps targeting novel biological control strategies such as paratransgenesis. here the bacterial microbiota of periplaneta americana midgut, were identified and evaluated for finding proper paratransgenesis candidate. methods : midgut ...

background: calf diarrhea is an important disease that is caused by different pathogens including bacteria, virus and parasites and is associated with economic losses. objectives: in this study, we evaluated the antibacterial activities of zatacin (z. multiflora aerial part ethanol extract), colistin, co-trimoxazole and enrofloxacin against clinical isolates of salmonella sp, e. coli and campyl...

Food-borne zoonoses have a major health impact in industrial countries. Campylobacter spp., Salmonella enterica, Yersinia enterocolitica and Listeria monocytogenes are high-risk food-borne zoonotic hazards in finishing pigs. The objectives of this work were (1) to study the isolation rate of pathogenic Y. enterocolitica, Salmonella spp., Campylobacter spp. and L. monocytogenes in the tonsils an...

although some venoms and their isolated compounds have been shown to have antibacterial properties, most have not been investigated for such activity. echis carinatus is one of the most venomous snakes in the world and has an effective haematotoxic venom that destroys endothelial cells and causes haemorrhagia. in this study, the antibacterial activity of iranian snake echis carinatus venom agai...

Paratyphoid is caused by Salmonella enterica serotype paratyphi A, B or C. There are only subtle clinical differences between the typhoid and paratyphoid but there is no difference between the response to therapy or frequency of complications [1]. Splenic infarction is an identified complication of typhoid and paratyphoid [2, 3]. However, there are only a few reports of spontaneous splenic rupt...
