The impact of chlortetracycline on Drosophila melanogaster and Aedes aegypti
… is not commonly addressed. The impact of chlortetracycline treatment on Aedes aegypti and Drosophila melanogaster was investigated by assessing life-span, fecundity, development time, survival, nutrition and metabolism. The impact on microbial numbers and diversity was also determined. …

The xenogenous capacitation response of fresh, cooled/extended and frozen/thawed equine semen as determined by a chlortetracycline stain
… 6 hours post-insemination, was assessed using a chlortetracycline (CTC) fluorescent probe. Data were recorded as percentages of spermatozoa exhibiting CTC staining patterns characteristic of capacitated (PCAP), unreacted (PUR) and acrosome reacted (PAR) sperm. Mean PCAP was not significantly …

Kinetic Modeling of Mesophilic Digestion of Swine Manure Containing an Antibiotic Inhibitor (Methane, Biogas)
… of swine manure containing the antibiotic chlortetracycline (CTC). The experimental design was set up to determine the effects retention time (RT) and antibiotic concentration had on the fermentation process. Also, addition of the pure form of the antibiotic to the control substrate was …

Removal of antibiotics from contaminated waters using natural zeolite
… work, the sorption of four antibiotics, namely chlortetracycline (CTC), oxytetracycline (OTC), ofloxacin (OFL), and enrofloxacin (ENR), on natural zeolite was investigated. The impact of pH and natural organic matter (NOM) on the sorption process was examined, and the maximum sorption capacity …

Tetracyclines In Swine Waste
… of three antibiotics in swine waste, namely chlortetracycline, tetracycline and oxytetracycline, using LC-MS with electrospray ionization is presented here in. Antibiotics from swine waste were quantified across the lifespan of the swine. Trends were present in each of the four life stages …

Effect of processing parameters on the detection of animal drug residues in milk
… spiked with sulfamethazine, penicillin G, and chlortetracycline at levels of 10, 10 and 30 ppb, respectively. Spiked milk and negative control milk was heat-treated, homogenized or heat-treated and homogenized. The procedures evaluated for penicillin detection were Bacillus stearothermophilus …

The effects and fate of selected veterinary antibiotics in two Missouri anaerobic swine lagoons
… A, and three tetracycline, tetracycline, chlortetracycline, and oxytetracycline degraded rapidly in buffered, distilled/deionized water that was maintained at temperatures and pH's commonly encountered in the two study lagoons. However, lincomycin, several studied sulfonamides, and tylosin …

Development of a liquid-liquid, solid-phase extraction (SPE), LC-MS/MS analytical method for qualitative and quantitative drug residue analysis in white-tailed deer
… analysis of veterinary drugs (florfenicol, chlortetracycline, tulathromycin, chloramphenicol, and ractopamine). To facilitate qualitative and quantitative analytical method development of veterinary drugs, a sample preparation method was developed to extract individual and multiple …
