Aerobic And Anaerobic

During this study canned food for dogs of six firms were investigated (42 samples totally). Microbiologically the following parameters were checked: the commercial sterility, the water activity (aw), the pH, the presence of aerobic and anaerobic bacteria after incubation of tins in 25 ° C for 28 days, 32 ° C for 21 days and 55 ' C for 8 days. Histologically, the existence of different kinds of tissues was examined. Technologically Weende's analysis and separation of the tin's content were made. Toxicologically, the concentration of lead and cadmium were countered. The results showed that dog's canned food, in Greece, are supersterillised. Muscular, adipose and connective tissue are used for their production as well as byproducts and soya proteins by some firms. The results of Weende's analysis are in full agreement with the amount of nutriments that they were written on tins' labels.

Low-acid vegetables were processed in a water-bath at 212° F. for one-half to three hours continuously and also intermittently, as in home canning. Peas, corn, and snap beans processed by these methods showed the presence of many types of surviving aerobic and anaerobic bacteria, but none showed spoilage when containers were effectively sealed. The same was found true for commercially canned products. The addition of 50% tomato juice to snap beans considerably reduced the number of bacterial survivors and made possible the greatest number of sterile containers, even with processing time of one and one-half hours.

Six preparations (four liquid and two solid) were tested in a double-blind crossover design for their anti-bacterial effect on aerobic and anaerobic bacteria in saliva of 12 volunteers. The four liquid preparations contained either tyrothricin, hexetidine, hydrogen peroxide or ethanol and were tested against a rinse with water as control. The two solid preparations, in the form of lozenges, contained tyrothricin in doses of 4 or 10 mg and were tested against parafilm. A single rinse with either tyrothricin or hexetidine resulted in a significant reduction of aerobic and anaerobic bacteria in saliva which lasted for the whole 1h observation period and was considerably more effective than hydrogen peroxide or ethanol. Similar results were seen with the solid preparations. The lozenge containing 10 mg tyrothricin was the most effective and was the only formulation capable of reducing oral aerobic bacterial counts by a factor of approximately 100.

Abstract When lead and cadmium were determined in samples of canned food by the AOAC anodic stripping voltammetric method, an interference was observed which was believed to be tin(IV). This interference could cause false positive results for lead and cadmium. The electroactivity of tin(IV) was suppressed by increasing the concentration of tartaric acid in the supporting electrolyte from 0.005M to 0.1M after mixing with an equal volume of sample solution.

ABSTRACT The 9-t-butylglycylamido derivative of minocycline (TBG-MINO) is a recently synthesized member of a novel group of antibiotics, the glycylcyclines. This new derivative, like the first glycylcyclines, theN,N-dimethylglycylamido derivative of minocycline and 6-demethyl-6-deoxytetracycline, possesses activity against bacterial isolates containing the two major determinants responsible for tetracycline resistance: ribosomal protection and active efflux. The in vitro activities of TBG-MINO and the comparative agents were evaluated against strains with characterized tetracycline resistance as well as a spectrum of recent clinical aerobic and anaerobic gram-positive and gram-negative bacteria. TBG-MINO, with an MIC range of 0.25 to 0.5 μg/ml, showed good activity against strains expressing tet(M) (ribosomal protection), tet(A), tet(B),tet(C), tet(D), and tet(K) (efflux resistance determinants). TBG-MINO exhibited similar activity against methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant streptococci, and vancomycin-resistant enterococci (MICs at which 90% of strains are inhibited, ≤0.5 μg/ml). TBG-MINO exhibited activity against a wide diversity of gram-negative aerobic and anaerobic bacteria, most of which were less susceptible to tetracycline and minocycline. The in vivo protective effects of TBG-MINO were examined against acute lethal infections in mice caused by Escherichia coli, S. aureus, andStreptococcus pneumoniae isolates. TBG-MINO, administered intravenously, demonstrated efficacy against infections caused byS. aureus including MRSA strains and strains containingtet(K) or tet(M) resistance determinants (median effective doses [ED50s], 0.79 to 2.3 mg/kg of body weight). TBG-MINO demonstrated efficacy against infections caused by tetracycline-sensitive E. coli strains as well asE. coli strains containing either tet(M) or the efflux determinant tet(A), tet(B), ortet(C) (ED50s, 1.5 to 3.5 mg/kg). Overall, TBG-MINO shows antibacterial activity against a wide spectrum of gram-positive and gram-negative aerobic and anaerobic bacteria including strains resistant to other chemotherapeutic agents. The in vivo protective effects, especially against infections caused by resistant bacteria, corresponded with the in vitro activity of TBG-MINO.

Back ground: Microbial penetration inside the implant's internal hole creates a bacterial reservoir that is related with an area of inflamed connective tissue opposite the fixture-abutment junction and this can affect the health of the peri-implant tissue. Aims of the study: Evaluate the types aerobic and anaerobic bacterial count-percentage and difference between Aerobic and Anaerobic microflora in the implant screw hole three months after implant placement. Monitor the periodontal health status of all patients, throughout the study. Material and methods: Study methodology; Eight partially edentulous patients received 20 dental implants and these implants done with flapless surgical procedure. All patients examined clinically to determined their oral health status by examination of their plaque index, Gingival index and Bleeding on probing, each two weeks for 90 days (8visits) throughout the study period. Three months after that, the plaque sample collected from the internal hole of fixture and transfer to bacterial investigation and assessment the amount of anaerobic and aerobic bacteria. Results: Although the anaerobic viable count is higher than that of aerobic, but with statistically not significant difference between those counts (P>0.05). Keywords: screw hole, flapless surgical implant placement, bacterial count, Aerobic and Anaerobic bacteria

This study concerns an assessment of a SBR operation that associates anaerobic aggregated biomass with a pulsed action during the reaction phase, a system named Pulsed Sequencing Batch Reactor (P-SBR). The system uses a diaphragm pump as a pulsator unit to increase the liquid-solid contact, in order to avoid dead zones and possible external mass transfer resistance. A preliminary study of the operation of the reactor was performed with a low strength synthetic wastewater with a COD near 1000 mg.1−1 and a sub-optimal temperature of 22°C. A removal efficiency of 60-70% was attained after 5 and 6 hours of reaction time. The respective organic loads were 5 – 6 kg COD.m−3. day−1, thus supporting the feasibility of the P-SBR system for wastewater treatment in such conditions. The results also indicate that a ratio of 1.8%o between the swept volume delivered by the pump and the reactor volume was adequate to promote a flow turbulence in the sludge blanket and that a redox potential of near −400 mV was readily created by anaerobic bacteria after the reactor filling step.

Adenoids and tonsils electively removed from 25 children with a history of recurrent group A β-hemolytic streptococci (GABHS) adenotonsillitis were cultured for aerobic and anaerobic bacteria. Two hundred twenty-four organisms (112 aerobes and facultatives, 110 anaerobes, and 2 Candida albicans) were isolated from the tonsils, and 229 (111 aerobes and facultatives and 118 anaerobes) were isolated from the adenoids. Mixed infection was present in all instances, with an average of 9.1 isolates per specimen. The predominant aerobes were Streptococcus sp, Haemophilus influenzae, and GABHS, and the prevalent anaerobes were Peptostreptococcus, Prevotella, and Fusobacterium spp. β-Lactamase-producing bacteria were detected in 72 isolates recovered from 22 tonsils (88%) and in 74 isolates recovered from 21 adenoids (84%). Discrepancies in the organisms recovered were found between the tonsils and adenoids. Of the aerobic isolates, 20% were isolated only in tonsils and 18% only in adenoids. Of the anaerobes, 20% were found only in tonsils and 26% only in adenoids. This study demonstrates a polymicrobial aerobic-anaerobic flora in both adenoids and tonsils, and discrepancies in recovery of pathogens such as GABHS. The adenoids may serve as a potential source of tonsillitis caused by GABHS.
