In the present study, endosulfan degrading capability of four bacterial monocultures (RCE-2, GCE-4, GCE-5 and JCE-4) and two bacterial mixed-cultures (GCE345 and GCC134) was investigated in terms of treatment duration and culture volume, using soil slurry medium. Among the bacterial mono-cultures, JCE-4 was found to be most efficient with 16, 33, 60 and 65% of endosulfan (α + β-isomers) degrada...

background: normal bacterial flora of the conjunctiva, which inhibits growth of opportunistic organisms, has an important role in the prevention of ocular infections. if resident flora is inhibited by disease or long-term application of antibiotics, opportunistic pathogens overgrow, leading to disease. objectives: the aim of this study was to investigate the effects of ophthalmic chloramphenico...

We report a skew-Laplace statistical analysis of both flow cytometry scatters and cell size from microbial strains primarily grown in batch cultures, others in chemostat cultures and bacterial aquatic populations. Cytometry scatters best fit the skew-Laplace distribution while cell size as assessed by an electronic particle analyzer exhibited a moderate fitting. Unlike the cultures, the aquatic...

Bacteriol. 84:154-156. 1962.-Reversal of the antibacterial activity of d-4-amino-3-isoxazolidone by alanine in bacterial cultures actively growing on chemically defined media was compared in cultures requiring exogenous alanine and those capable of its synthesis. dl...

Abstract Study question What is the situation of bacterial semen infections in North African men between 2013 and 2022? Summary answer The proportion positive-bacterial-semen-cultures North-Afrian was 5.9%: Tunisian-patients positive rate 5.8%. Algerians 7.9% Lybian 4.7%. known already Numerous bacteria can influence spermatogenesis process at different levels disrupt spermatozoa development, m...

The fate and impact of elemental mercury in closed bacterial cultures were examined. The quantity of elemental mercury oxidized by bacteria ranged from small amounts for Pseudomonas aeruginosa, P. fluorescens, Escherichia coli, and Citrobacter to essentially all of the added elemental mercury for Bacillus subtilis and B. megaterium. The percentage of the total mercury in the system associated w...

Amphibians possess beneficial skin bacteria that protect against the disease chytridiomycosis by producing secondary metabolites that inhibit the pathogen Batrachochytrium dendrobatidis (Bd). Metabolite production may be a mechanism of competition between bacterial species that results in host protection as a by-product. We expect that some co-cultures of bacterial species or strains will resul...

Chronic bronchitis is common among smokers, often together with recurrent infectious exacerbations. Streptococcus pneumoniae and Haemophilus influenzae are the pathogens traditionally considered most important. N-acetylcysteine (NAC) treatment has been shown to reduce the number of infectious exacerbations in patients with chronic bronchitis. The mechanism behind this is unknown. We attempted t...

Ammonium was shown to be a limiting nutrient for iron oxidation in cultures of Thiobacillus ferrooxidans. In addition, one strain was also able to assimilate nitrate, but not nitrite, for growth and coupled iron oxidation. Some amino acids (0.5 mM) were tested as a source of nitrogen; none clearly stimulated bacterial activity and inhibition was commonly encountered. Complex nitrogenous compoun...

A prospective observational study was conducted at J. N. Medical College, Aligarh Muslim University, to compare the bacterial flora obtained from sequestrum culture and sinus track culture and to evaluate their antibiotic sensitivity. A total of 62 patients with chronic osteomyelitis were enrolled (38 males and 24 females). Sinus track cultures were done taking all aseptic precautions and the r...
