INTRODUCTION American cockroaches, Periplaneta americana, are the most important pests in hospitals and dwelling environments. They are mechanical vectors of some bacterial pathogens. GOAL The present investigation was carried out in Ghods hospital and 5 dwelling localities of Paveh city to evaluate bacterial infestations of American cockroaches in this region of Iran. METHODS The samples w...

The aim of this study was to analyse the qualitative composition of Gram-negative microbes, mainly of the family Enterobacteriaceae, including pathogenic bacteria such as Salmonella, in the albumens and yolks and on the shells of hens' eggs, depending on their source and on the temperature and duration of their storage. A total of 375 table eggs were studied, from a large-scale poultry farm, a ...

DE protection, demineralization, de colorization, and acetylation. Protein accesses were used to obtain chitosan from shrimp shell waste. Using FTIR, SEM XRD. It was characterized. Also analyzed the physiochemical parameter such as moisture content, hydrogen meter, viscosity, degree of acetylation solubility The age bacterial culture influenced its susceptibility with cells being most prone in ...

background:cystitis and pyelonephnitis in ruminants mostoften result from ascending urinary tract infection (uti).objectives: investigating the prevalence of urine infection andits relationship with histopathological findings of bladder andkidney. methods: this study was carried out on 353 slaughteredbuffalos (143 female and 210 male) at ahvaz abattoir, southwest ofiran. after slaughter, urinar...

The antibacterial activity of leaf and root ethanolic extracts as well as crude alkaloids and flavonoids from both the parts of Rhus succedanea were carried against bacterial strains viz. Staphylococcus aureus, Clavibacter michiganensis, Proteus vulgaris and Xanthomonas spp. The antibacterial activity was carried out on nutrient agar medium using disk diffusion method. The flavonoid fraction of...

rheum ribes is among the polygonaceae family which is endemic in iran and a few neighboring countries. in this investigation, antibacterial effects of root, stalk and leaves extracts of rheum ribes on a few common clinical isolates of gram negative pathogens were studied, using the cup plate and paper disc methods. gram negative microorganisms studied were escherichia coli, klebsiella pneumonia...

BACKGROUND Proteus spp. bacilli belong to opportunistic human pathogens, which are primarily responsible for urinary tract and wound infections. An important virulence factor is their ability to form biofilms that greatly reduce the effectiveness of antibiotics in the site of infection. OBJECTIVES The aim of this study was to determine the value of the minimum concentration of ciprofloxacin t...

The major aim of this study was to characterize a soluble Plasmodium falciparum antigen from the plasma of malaria-infected humans and Plasmodium falciparum culture supernatants, using immunoabsorbent techniques and Western blotting. An Mr 60-kDa protein was isolated from the plasma of patients with Plasmodium falciparum malaria by affinity chromatography using rabbit anti-Proteus spp GDH(NADP+...

Trimethoprim resistance is increasingly prevalent in community-acquired urinary infections. The objective of this study was to evaluate the association between exposure to community-prescribed trimethoprim and other risk factors in subjects and subsequent trimethoprim-resistant urinary tract infection. The design was a nested case-control study using a record-linkage database. Study subjects su...
