The effects of acriflavine on two species of Trypanosomatidae, Crithidia luciliae and Trypanosoma mega, have been investigated. It has been observed that kinetoplastic (i.e. mitochondrial) DNA is lost in a high percentage of acriflavine-treated cells. Resting flagellates, from stationary-phase or hemin-deficient cultures, are considerably more resistant to the acridine than are flagellates from a log-phase culture. When the kinetoplast has retained some DNA and still remains visible in stained smears, it appears reduced in size, and its ultrastructure is extremely abnormal: the DNA fibrils, clearly visible in normal kinetoplasts, are condensed; they appear as an electron-opaque, apparently homogeneous mass, separated from the membranes by a space of low electron-opacity. Analyses of DNA extracts, with high speed centrifugation in CsCl density gradients, revealed that the satellite band, presumably kinetoplastic DNA, is lost by trypanosomes grown for 5 days in the presence of acriflavine. ...
Results Markerless deletion mutants were constructed to analyze the impact of the so far uncharacterized RND proteins in S. aureus. While the lack of Sa2056 and Sa2339 caused no phenotype regarding growth and resistance, the secDF mutant resulted in a pleiotropic phenotype. The secDF mutant was cold sensitive, but grew normally in rich medium at 37°C. Resistance to beta-lactams, glycopeptides and the RND substrates acriflavine, ethidium bromide and sodium dodecyl sulfate was reduced. The secDF mutant showed an aberrant cell separation and increased spontaneous and Triton X-100 induced autolysis, although the amounts of penicillin-binding proteins in the membrane were unchanged. The impact of secDF deletion on transcription and expression of specific virulence determinants varied: While coagulase transcription and activity were reduced, the opposite was observed for the autolysin Atl. A reduction of the transcription of the cell wall anchored protein A (spa) was also found. The accumulation of ...

The multidrug (chloramphenicol, tetracycline, norfloxacin, doxorubicin, trimethoprim, acriflavin, ethidium bromide, tetraphenylphosphonium, TPP, benzalkonium, ciprofloxacin, thiamphenicol, IPTG) resistance exporter, MdfA (catalyzes both electrogenic and electroneutral transport) (Adler and Bibi, 2004). Can function as a Na+ (K+)/H+ antiporter (Lewinson and Bibi 2001; Higgins, 2007). Is known to provide resistance to a wide variety of dissimilar toxic compounds, including neutral, cationic and zwitterionic substances. Crystals that diffracted to 3.4 Å resolution and belonged to the hexagonal space group P6122 have been obtained (Nagarathinam et al. 2017). For review of MdfA see Lewinson et al., 2006. The conformational switch accompanying transport is induced by promiscuous binding of substrates and/or inhibitors to the binding pocket (Fluman et al., 2009). Normally extrudes monovalent cationic drugs in exchange for a single proton, but it transports divalent cationic drugs poorly. It can be ...

Ozone is the ONLY single method we have of destroying free-swimming parasites, bacterium and viruses. It also literally burns up organics and phenols. Due to the relatively short life span of ozone it quickly reverts to oxygen enriching the water quality. Obviously, improved water quality combined with the high oxygen content and the lack of bacteria to cause primary and secondary infections gives a huge boost to the livestocks own immune system enabling speedy recover from knocks, parasite infestation, bacterial infections. Another major benefit is the prevention of cross infection in centralised systems. Systems using ozone generators do not require regular dosing of medications such as malachite green, formaline, acriflavine or antibiotics. If they were to be administered the ozone generated would burn them out. Why do we need a ORP Controller/Meter and Probe? The ORP uses a probe, which is normally situated in the system reservoir to continually monitor and provide an accurate and. ...
Hi, I have tried without luck to cure the growth on my goldfish but with no luck. Now that the growth on my fish has grown I have better quality pics that may help diagnosis and treatment.

Nothing seems to have worked. Im always scared of overdosing medications so maybe I didnt use enough or for as long as
The presence of putative ebrAB genes in the chromosomal DNA of B. subtilis has been revealed by whole-genome sequencing (9). Judging from the similarity of the deduced amino acid sequences between EbrA or EbrB and members of SMR family of multidrug efflux proteins, it seemed that the EbrAB is responsible for ethidium bromide resistance. We cloned the ebrAB genes fromB. subtilis ATCC 9372 and expressed them in E. coli cells. In fact, our data suggest that the EbrAB is a multidrug efflux pump and is involved in multidrug resistance against cationic lipophilic dyes such as ethidium bromide, acriflavine, pyronine Y, and safranin O. Three signature sequences that are specific to the SMR family members (19) were all present in deduced amino acid sequences of EbrA and EbrB (data not shown). Thus, we believe that the EbrAB is a member of the SMR family.. Each member of the SMR family so far reported is encoded by a single gene. Smr of S. aureus (6) and EmrE of E. coli (25) have been purified to ...
Several efflux proteins are well described in gram-positive bacteria, including Bmr in Bacillus subtilis (1) and NorA in Staphylococcus aureus (15). These can mediate low-level resistance to hydrophilic fluoroquinolones and a variety of unrelated compounds; both are inhibited by reserpine (14, 15). More recently, reserpine was shown to inhibit the level of accumulation of ethidium bromide in an ethidium bromide-selected mutant of S. pneumoniae which showed cross-resistance to fluoroquinolones (5). For this reason we used reserpine to detect mutants resistant to fluoroquinolones by an efflux mechanism.. We showed that reserpine significantly increased the activity of norfloxacin against several norfloxacin-selected mutants. These presumptive efflux mutants also showed increased levels of resistance to ethidium bromide and acriflavine, which agrees with the description by Zeller et al. (20) of the presence of an efflux pump in pneumococci. Ethidium bromide accumulation in strain 1N27, a ...

Monoclonal antibody (MAb) 4E8C12 has been previously reported to recognise low mol. wt proteins from enterohaemorrhagic Escherichia coli (EHEC) serotypes O157:H7 and O26:H11. Crude lipopolysaccharide (LPS) preparations from proteinase K-digested bacterial suspensions reacted in Western blots with MAb 4E8C12, as did highly purified LPS from O157:H7 strains. The material recognised by this antibody was, therefore, LPS. The LPS epitope was identified by a whole-cell ELISA in several EHEC, verotoxin producing E. coli (VTEC) and verotoxin-negative strains in addition to E. coli serotypes O157:H7 and O26: H11. Acriflavine and bile salts enhanced the production or availability of the epitope at the cell surface and in culture supernates. These data indicate that the presence of the epitope did not correlate with the virulence of these organisms.
Chip Flory. From The Editor. June 29, 2012. Hello Pro Farmer Members!. Its not very often the June Acreage Report from USDA can add 2.315 million acres to expected soybean harvested acres and the market can close higher. Planted soybean acres were about 500,000 above the average pre-report trade estimate, so the harvested acreage number blew-away trade expectations, as well.. Nonetheless, soybean futures charged higher again today. Without stress-relieving rains in the near-term, the contract high in November soybeans set earlier this week will likely get pushed aside next week.. The counter to the bigger-than-expected increase in soybean acres is a declining yield estimate. In this weeks Pro Farmer, we stayed conservative with our national average soybean yield assumption and put it at 43 bu. per acre. Thats down 0.9 bu. from USDAs projection in the June S&D Report, but its above many crop-watchers yield peg. One of those lower estimates is reportedly coming from Informa Economics. Source ...

Experiments at the University of Florida Tropical Aquaculture Laboratory were run to test various shipping chemical additives for their effects on appearance and behavior of fish post shipping. The chemicals tested were tricaine methanesulfonate (MS-222), salt (3 ppt NaCl), methylene blue, acriflavine neutral, quinaldine, eugenol, an experimental commercial product in the form of a feed, and a water additive.. The commercial product contained arachidonic acid (ArA), a fungus extract from Mortierella sp., claimed by the manufacturer to be used to regulate immune systems; and an ethanol extract from the genus Opuntia, a cactus species, claimed by the manufacturer to be used to stimulate the production of heat shock proteins (HSPs) that work to counteract stress responses.. Tricaine methanesulfonate is approved for use in finfish as a sedative and anesthetic. Quinaldine and eugenol are not approved for use in aquaculture.

Erysipelothrix rhusiopathiae is a primary pathogen of swine and turkeys and sporadic cause of disease in a variety of other hosts, including humans. A genomic library of the highly virulent strain of E. rhusiopathiae E1-6P was constructed in the expression-cloning vector lambda gt11 and screened with serum from a pig convalescent from an E. rhusiopathiae experimental infection. Immunoreactive clones were screened for their ability to protectively immunized mice. Two clones, lambda gt11/ersA and lambda gt11/ersB, were obtained that protected mice against challenge with E. rhusiopathiae E1-6P. Antisera against the recombinant clones reacted with polypeptides of molecular weights 66,000, 64,000, and 43,000 in detergent-solubilized surface antigen preparations and whole-cell lysates of E. rhusiopathiae. These polypeptides were also the major antigens recognized by convalescent pig serum when reacted with the same preparations. Western immunoblot and Southern blot analysis revealed that the cloned ...

Acres Treated is the acreage of the crop actually treated with the pesticide. Gross Pounds applied divided by Acres Treated is the application rate of the pesticide. The difference between Acres Planted and Acres Treated is best explained through an example:If a farmer has a 100-acre field and sprays 50 acres, then the Acres Planted will be 100 and the Acres Treated will be 50. If a farmer sprays 50 of their 100 acres three times, then the Acres Planted will remain at 100 acres, but now the value of Acres Treated will be 150. This figure may not be the total acreage of the selected crop. See documentation for further distinctions between acres treated and acres planted ...
