“…For [24]. Campylobacters can survive the purification process in the plants [7], so the effluent can act as a vehicle for the spread of resistant campylobacter organisms in the environment. As surface waters are recognized as sources of human campylobacter infections, it is important to continue surveillance of resistance in campylobacter strains isolated from surface waters and other aquatic environments.…”

“…Campylobacter strains were isolated on selective CCD plates [7]. Confirmation of identity of suspected campylobacter isolates was based on microscopic appearance, resistance to cephalothin (KF Oxoid, Basingstoke, UK, 30 ,ug), growth under micro-aerobic conditions in Brain Heart Infusion Broth (BHI, 0037-01-6 Difco Laboratories, Detroit, USA) at 42°C (+) and 25°C (-), presence of oxidase (+) and catalase (+).…”

“…In particular, poultry abattoir effluent may contain high numbers of campylobacters and as these organisms can easily pass sewage purification plants, it constitutes an important contamination source for surface water [6][7][8][9]. An epidemiological study on the distribution and diversity of campylobacter in a sewage purification plant and poultry abattoir drain water from this plant showed several common phenotypes [10].…”

SUMMARYIn this study, the in vitro susceptibility of 209 campylobacter strains to the quinolones nalidixic acid, flumequine, ciprofloxacin, enrofloxacin, and to ampicillin, tetracycline and erythromycin was tested by the disk diffusion method. The strains were isolated from poultry abattoir effluent (DWA) and two sewage purification plants (SPA and SPB). Sewage purification plant SPA received mixed sewage, including that from a poultry abattoir, whereas SPB did not receive sewage from any meat-processing industry. The quinolone resistance of the DWA isolates ranged from 28 % for enrofloxacin to 50 % for nalidixic acid. The strains isolated from the sewage purification plants were more susceptible to the quinolones with a range of 11-18% quinolone resistance for SPB isolates to 17-33% quinolone resistance for SPA isolates. The susceptibility criteria as recomnmended by National Committee Clinical Laboratory Standards (USA) cannot readily be employed for campylobacter isolates. This investigation shows that the resistance of campylobacter bacteria is highest in the plant receiving sewage from a poultry slaughterhouse. Monitoring of antibiotic resistance of aquatic Camnpylobacter spp. is important, as surface waters are recognized as possible sources of infection.

“…Many studies have found Campylobacter in aquatic environments; in fact, its recovery is common and widespread [ Table 3 (38,39,]. Sewage treatment (86)(87)(88)(89)(90)(91) and water-treatment processes (84,85) are less than perfect ecologic filters. Animal access to drinking water catchments and proximity to rivers would seem to be an important factor in determining exposure through aquatic ecosystems.…”

Pathogen survival trajectories: an eco-environmental approach to the modeling of human campylobacteriosis ecology.

Campylobacteriosis, like many human diseases, has its own ecology in which the propagation of human infection and disease depends on pathogen survival and finding new hosts in order to replicate and sustain the pathogen population. The complexity of this process, a process common to other enteric pathogens, has hampered control efforts. Many unknowns remain, resulting in a poorly understood disease ecology. To provide structure to these unknowns and help direct further research and intervention, we propose an eco-environmental modeling approach for campylobacteriosis. This modeling approach follows the pathogen population as it moves through the environments that define the physical structure of its ecology. In this paper, we term the ecologic processes and environments through which these populations move "pathogen survival trajectories." Although such a modeling approach could have veterinary applications, our emphasis is on human campylobacteriosis and focuses on human exposures to Campylobacter through feces, food, and aquatic environments. The pathogen survival trajectories that lead to human exposure include ecologic filters that limit population size, e.g., cooking food to kill Campylobacter. Environmental factors that influence the size of the pathogen reservoirs include temperature, nutrient availability, and moisture availability during the period of time the pathogen population is moving through the environment between infected and susceptible hosts. We anticipate that the modeling approach proposed here will work symbiotically with traditional epidemiologic and microbiologic research to help guide and evaluate the acquisition of new knowledge about the ecology, eventual intervention, and control of campylobacteriosis.
