“…Hoogenboom et al (2008) mentioned that Campylobacter farm and sample prevalence was much lower on conventional than on organic broiler farms, but did not provide a significance level. Rosenquist et al (2013) mentioned that carcass prevalence at slaughter was significantly higher in organic compared to conventional broilers without providing a significance level, and found no difference (p=0.428) in the mean concentration.…”

“…Three studies related to farm level, four to both farm and slaughterhouse level, and two to retail level. On farm and processing level, two studies did not provide significance levels for comparing organic and conventional (Hoogenboom et al, 2008;Ranta et al, 2010). In six of the studies, samples originated from ten or less farms, supermarkets or brands (be it conventional, organic or both).…”

“…Bonde and Sørensen (2012) collected samples at 11 conventional and 11 organic farms, and Rutjes et al (2014) at 24 conventional and 42 organic farms. Hoogenboom et al (2008) compared the average result of 30 organic farms to the national average. Generalising the results from these papers to the entire organic and conventional sectors is therefore complicated.…”

“…Of these, three concerned the farm level (Garcia-Migura et al, 2005;Hoogenboom et al, 2008;Nulsen et al, 2008), and two the retail level (Miranda et al, 2008b;Guarddon et al, 2014). Four studies concerned Europe and one New Zealand.…”

This study analysed peer-reviewed literature comparing conventional and organic livestock production systems on sustainability indicators within the topics of economy, productivity, environment, animal welfare and public health. For many indicators, insufficient data were found to draw any conclusions on a difference. The strong points of both conventional and organic livestock production systems were used to formulate lessons learned for sustainable livestock production systems. As sustainability indicators often interact with other sustainability indicators in opposing directions, sustainable livestock production should be approached as a multi-criteria problem optimising a balanced combination of sustainability indicators in all topics.Deze studie heeft wetenschappelijke literatuur geanalyseerd, die conventionele en biologische dierlijke productiesystemen kwantitatief vergelijkt op duurzaamheidsindicatoren binnen de onderwerpen economie, productiviteit, milieu, dierenwelzijn en volksgezondheid. Voor veel indicatoren zijn onvoldoende gegevens gevonden om conclusies te trekken over een verschil. Gevonden sterke punten van zowel conventionele als biologische systemen zijn gebruikt om lessen te trekken voor duurzame veehouderij. Aangezien duurzaamheidsindicatoren vaak onderling samenhangen in tegenstrijdige richting moet een duurzame veehouderij gezien worden als een multicriteria beslissingsprobleem, waarin een gebalanceerde combinatie van indicatoren uit alle duurzaamheidsonderwerpen moet worden geoptimaliseerd.

“…Estudos revelam uma prevalência de Campylobacter spp. em frangos de criação orgânica entre 60% a 100% (Heuer et al 2001, El--Shibiny et al 2005, Overbeke et al 2006, Colles et al 2008, Esteban et al 2008, Hoogenboom et al 2008, EFSA 2010. Dentro desse contexto, objetivou-se com esta pesquisa investigar a ocorrência de Campylobacter jejuni e C. coli em frangos de criação orgânica e determinar sua suscetibilidade à ciprofloxacina e enrofloxacina através de métodos fenotípicos e genotípicos.…”

ABSTRACT.-Frasão B.S., Côrtes L.R., Nascimento E.R., Cunha N.C., Almeida V. Studies have shown that resistance to quinolones in Campylobacter strains is related with Threonine-86-Isoleucine mutation. In order to investigate the presence of this mutation in sensitive and resistant Campylobacter strains to ciprofloxacin and enrofloxacin, the cecal contents of 80 broilers from organic raising chickens, slaughtered under State Inspection Service (S.I.S) of the State of Rio de Janeiro, were collected and tested for the presence of Campylobacter. The determination of ciprofloxacin and enrofloxacin susceptibility was done by disk diffusion and agar dilution methods for determining the Minimum Inhibitory Concentration (MIC). The detection of mutation in Quinolone Resistance Determinant Region (QRDR) in gyrA gene was done by sequencing. Campylobacter was isolated from 100% of the samples, being 68.75% C. jejuni and 31.25% C. coli. By the disk diffusion method, resistance to ciprofloxacin was observed in all isolates and 56.25% of the strains were resistant to enrofloxacin. By agar dilution method, all strains were resistant to ciprofloxacin (MIC ≥ 16µg/mL to ≥ 64µg/mL) and full and intermediate resistance to enrofloxacin was detected in 42.50% (MIC ≥ 4-32μg/mL) and 38.75% (MIC =2μg/mL) of the strains, respectively. Mutation Thr-86-Ile was observed in 100% of the isolates investigated. In addition to this mutation, others no silent mutations and silent mutations (His-81-His, Ser-119-Ser, Ala-120-Ala, Phe-99-Phe, Ala-122-Ala, Gly-74-Gly, Ile-77-Ile, Ala-91-Ala, Leu-92-Leu, Val-93-Val, Ile-106-Ile, Thr-107-Thr, Gly-113-Gly, Ile-115-Ile, Gly-110-Gly) were detected. All the enrofloxacin--sensitive strains by the phenotypic methods had the Thr-86 to Ile substitution, which suggests other mechanisms contributing to enrofloxacin resistance in Campylobacter.
