A total number of 450 blood samples were collected from 45 different randomly selected cattle herds. Light microscopic examination of blood smears revealed Babesia spp. infection in 4.2%, while 8.9% of blood samples were positive using PCR. Upon multiplex-PCR (mPCR), B. bigemina and B. bovis infections were detected in 37/40 (92.5%) and 3/40 (7.5%) samples, respective...
Listeria monocytogenes is the bacterial causative agent of listeriosis, a life-threatening disease for humans, mainly transmitted through contaminated food. Human clinical isolates pathogen are frequently identified as serotype 4b strains; interestingly, however, (lineage I) normally underrepresented among food in which 1/2a II) usually prevalent. The present study aimed to assess situ dominanc...
اسهال ویروسی گاو (bvd) یک عامل بیماری¬زا است که در گاوها ایجاد عفونت می¬کند و اهمیت اقتصادی در جهان دارد. این ویروس موجب خسارت¬های اقتصادی قابل توجه بر صنعت دام¬پروری می¬شود. در این پژوهش با کمک 3 روش متفاوت شناسایی ویروس با نانو ذرات طلا انجام گرفت و شرایط واکنش بهینه شد. این 3 روش شامل نانو ذرات اصلاح نشده، نانو ذرات اصلاح شده به کمک 2 پراب و تک پراب بود. در هر سه روش تغییر رنگ در نمونه های ک...
BACKGROUND Genital mycoplasmas are opportunistic bacteria that are associated with undesirable gynaecologic and reproductive events. Mycoplasmas are fastidious bacteria with increasing resistance to routine antimicrobials and often fail to grow on conventional culture methods. The commercial Mycofast Revolution assay permits the phenotypic detection and identification of genital mycoplasmas. An...
Tomato production in the Mediterranean region and elsewhere is under constant threat of the whitefly-transmitted begomoviruses that cause Tomato yellow leaf curl disease (TYLCD). Sequencing has indicated that the generic ‘TYLCV’ includes a large number of viruses and strains. We studied the distribution of the tomato yellow leaf curl disease-associated viruses in Egypt, Israel, Jordan and Leban...
Food poisoning by staphylococcal enterotoxins (SE) is a major cause of foodborne illness, often associated with coagulase-positive staphylococci (CPS). The increase in the number methicillin-resistant Staphylococcus aureus (MRSA) strains another problem CPS. However, reports association SE and coagulase-negative (CNS) are beginning to re-emerge. In this context, aim study investigate presence e...
Urinary tract infections (UTIs) are among the most common bacterial infections and are responsible for significant morbidity and health care costs worldwide. The main bacterial cause of uncomplicated UTI is Escherichia coli, which possesses numerous virulence factors (VFs). Many studies of the pathogenesis of E. coli UTI have centered on VF genes. Hence, the development of better molecular assa...
We study the effect of group size on cooperation in voluntary contribution mechanism games. As in previous experiments, we study fourand eight-person groups in high and low marginal per capita return (MPCR) conditions. We find a positive effect of group size in the low MPCR condition, as in previous experiments. However, in the high MPCR condition we observe a negative group size effect. We ext...
botulism is a serious paralytic disease caused by clostridium botulinum toxin in foods. there are seven recognized serotypes of botulinum neurotoxins among which the principal prevalent types in humans include a, b and e. infant botulism results from intestinal colonization and toxin production by c. botulinum spores in babies less than 1 year old. honey is the most important food discriminated...
