“…The analysis by sample source showed that the poultry farm isolates had the higher number of resistant isolates containing more tet gene types simultaneously. Identical results were reported in a study carried out in swine sewage ponds, where the isolates most often harbour multiple tet genes [55].…”

Prevalence of Antibiotic Resistance Genes in Multidrug-Resistant Enterobacteriaceae on Portuguese Livestock Manure

The exposure of both crop fields and humans to antibiotic-resistant bacteria in animal excreta is an emergent concern of the One Health initiative. This study assessed the contamination of livestock manure from poultry, pig, dairy farms and slaughterhouses in Portugal with resistance determinants. The resistance profiles of 331 Enterobacteriaceae isolates to eight β-lactam (amoxicillin, cefoxitin, cefotaxime, cefpirome, aztreonam, ceftazidime, imipenem and meropenem) and to five non-β-lactam antibiotics (tetracycline (TET), trimethoprim/sulfamethoxazole (SXT), ciprofloxacin (CIP), chloramphenicol (CHL) and gentamicin) was investigated. Forty-nine integron and non-β-lactam resistance genes were also screened for. Rates of resistance to the 13 antibiotics ranged from 80.8% to 0.6%. Multidrug resistance (MDR) rates were highest in pig farm samples (79%). Thirty different integron and resistance genes were identified. These were mainly associated with resistance to CHL (catI and catII), CIP (mainly, qnrS, qnrB and oqx), TET (mainly tet(A) and tet(M)) and SXT (mostly dfrIa group and sul3). In MDR isolates, integron presence and non-β-lactam resistance to TET, SXT and CHL were positively correlated. Overall, a high prevalence of MDR Enterobacteriaceae was found in livestock manure. The high gene diversity for antibiotic resistance identified in this study highlights the risk of MDR spread within the environment through manure use.

“…Only tet (C) was not correlated with the relative abundance at least one bacterial genus. It is unclear whether these associations represent a higher prevalence of these genes among the four genera; however, Corynebacterium and Dietzia isolated from swine manure pits and associated soils have been reported to be reservoirs of tetracycline resistance determinants, including tet (B) [ 58 ]. In fact, five tet and four erm genes have been identified within the Corynebacterium genus, including tet (M), tet (W), erm (B), and erm (X) ( http://faculty.washington.edu/marilynr/ ).…”

Effect of Co-Composting Cattle Manure with Construction and Demolition Waste on the Archaeal, Bacterial, and Fungal Microbiota, and on Antimicrobial Resistance Determinants

et al. 2016

Agricultural operations generate large quantities of manure which must be eliminated in a manner that is consistent with public health guidelines. Meanwhile, construction and demolition waste makes up about 25% of total solid municipal waste. Co-composting of manure with construction and demolition waste offers a potential means to make manure safe for soil amendment and also divert construction and demolition waste from municipal landfills. Therefore, the archaeal, bacterial, and fungal microbiota of two different types of composted cattle manure and one co-composted with construction and demolition waste, were assessed over a 99-day composting period. The microbiota of the three compost mixtures did not differ, but significant changes over time and by sampling depth were observed. Bacillus and Halocella, however, were more relatively abundant in composted manure from cattle fed dried distillers’ grains and solubles. Proteobacteria and Bacteroidetes were enriched at day 0 and Firmicutes at day 99. The fungal genus Kernia was the most relatively abundant overall and was enriched at day 0. The concentration of 12 antimicrobial resistance determinants in the compost mixtures was also determined, and 10 of these determinants decreased significantly from days 0 to 99. The addition of construction and demolition waste did not affect the persistence of antimicrobial resistance genes or community structure of the compost microbiota and therefore co-composting construction and demolition waste with cattle manure offers a safe, viable way to divert this waste from landfills.

“…Антибіотики складають групу органічних сполук, що мають широкий спектр функціональних груп, які впливають на їх хімічні властивості, характеризуються гідрофобністю, їх розчинність у воді інколи перевищує 1г/л. Тобто окремі антибіотики здатні легко поширюватись і накопичуватись у середовищі [7,18].…”

In the article theve have been discussed the main directions of use of antimicrobial agents in the food industry and the consequences of formation of reservoir of antibiotic resistance of microorganisms for the healthcare system. The main emphasis was made on the differences between the control of use of antibiotics in animal husbandry in the European Union, the USA and Ukraine, as well as the quality of informing healthcare services about detection of resistant strains of microorganisms.
