plant growth promoting rhizobacteria (pgpr) are known to influence plant growth by various director indirect mechanisms. thirty–two strains were isolated from 15 soils sampled in central iran, byusing and comparing three different methods. the screening of soil samples by means of soil paste–plate method combined with isolation on mannitol agar proved to be the best strategy in terms ofreliabil...

A total of 47 psychrotrophic pseudomonads isolated from raw milk came from Newfoundland (19 isolates), British Columbia (6 isolates), Ontario (19 isolates), and Cork, Ireland (3 isolates). The susceptibility of these was tested against 30 bacteriophages isolated from cold-storage beef. Distinct lysotypes were observed with isolates representing different geographic regions. Phages as agents in ...

Abstract Staphylococcal enterotoxins (SE) are essential in human and animal infection food poisoning. This study analyzed ten genes ( sek, sel, sem, sen, seo, sep, seq, ser, ses , set ) encoding new staphylococcal enterotoxin isolated from animals humans by multiplex polymerase chain reaction (PCR). In Yogyakarta, Indonesia, samples cases (174 isolates), cattle (5 goats isolates) resulted a tot...

Bacterial spot, caused by Xanthomonas spp., is one of the most important diseases tomato in Illinois. Field surveys were conducted during 2017–19 to assess occurrence bacterial spot commercial fields. Severity foliage and fruit infection was recorded, symptomatic samples collected from three-to-five cultivars three different farms each northern, central, southern regions ranged 0% 91% (average ...

The goal of this study was to isolate and identify Staphylococcus aureus from clinical environmental sources. This also looked at the prevalence distribution different virulence enzymes among its isolates. For objective, 65 samples were collected dispersed 50 distinct 15 (soil, water, air) samples. results revealed that 20 bacterial isolates S. aureus. isolation rate 30.76% all samples, with 13...

We are interested in the root microbiome of the fast-growing Eastern cottonwood tree, Populus deltoides. There is a large bank of bacterial isolates from P. deltoides, and there are 44 draft genomes of bacterial endophyte and rhizosphere isolates. As a first step in efforts to understand the roles of bacterial communication and plant-bacterial signaling in P. deltoides, we focused on the preval...

OBJECTIVE To determine the trends of conjunctival sac bacterial flora isolated from patients prior to cataract surgery. SUBJECTS AND METHODS The study comprised 579 patients (579 eyes) who underwent cataract surgery. Specimens were collected by lightly rubbing the inferior palpebral conjunctival sac with a sterile cotton swab 2 weeks before surgery, and then cultured for isolation of bacteria...

The halophilic bacterial isolates SS1, SS2, SS3, SS5, and SS8 were characterized for production of industrially important enzymes like amylase, protease, lipase, and glutaminase. Halophilic bacterial isolates SS1 and SS3 exhibited salt dependent extracellular amylase and protease activities. Both the halophilic isolates SS1 and SS3 exhibited maximum amylase and protease activities in the presen...

One of the most common bacterial illnesses worldwide is urinary tract infections (UTIs). Out 228 urine specimens collected from a patient with suspected UTIs, 40 (17.5%) Proteus mirabilis isolates were identified, first identified as related to culture, microscopic examination, and biochemical tests. DNA was extracted these isolates, sample's nucleic acid purity ranged (1.8-2) while its concent...

Bacterial distribution and antimicrobial drug resistance were monitored in patients with bacterial bloodstream infections in rural hospitals in Ghana. In 2001-2002 and in 2009, Salmonella enterica serovar Typhi was the most prevalent pathogen. Although most S. enterica serovar Typhi isolates were chloramphenicol resistant, all isolates tested were susceptible to ciprofloxacin.
