Abstract
Chickens are the primary reservoirs of Campylobacter spp., mainly C. jejuni and C. coli, that cause human bacterial gastrointestinal infections. However, genomic characteristics and antimicrobial resistance of Campylobacter spp. in low- to middle-income countries need more comprehensive exploration. This study aimed to characterize 21 C. jejuni and 5 C. coli isolates from commercial broilers and native chickens using whole genome sequencing and compare them to 28 reference Campylobacter sequences. Among the 26 isolates, 13 sequence types (ST) were identified in C. jejuni and 5 ST in C. coli. The prominent ST was ST 2274 (5 isolates, 19.2%), followed by ST 51, 460, 2409, and 6455 (2 isolates in each ST, 7.7%), while all remaining ST (464, 536, 595, 2083, 6736, 6964, 8096, 10437, 828, 872, 900, 8237, and 13540) had 1 isolate per ST (3.8%). Six types of antimicrobial resistance genes (ant(6)-Ia, aph(3')-III, blaOXA, cat, erm(B), and tet(O)) and one point mutations in the gyrA gene (Threonine-86-Isoleucine) and another in the rpsL gene (Lysine-43-Arginine) were detected. The blaOXA resistance gene was present in all isolates, the gyrA mutations was in 95.2% of C. jejuni and 80.0% of C. coli, and the tet(O) resistance gene in 76.2% of C. jejuni and 80.0% of C. coli. Additionally, 203 virulence-associated genes linked to 16 virulence factors were identified. In terms of phenotypic resistance, the C. jejuni isolates were all resistant to ciprofloxacin, enrofloxacin, and nalidixic acid, with lower levels of resistance to tetracycline (76.2%), tylosin (52.3%), erythromycin (23.8%), azithromycin (22.2%), and gentamicin (11.1%). Most C. coli isolates were resistant to all tested antimicrobials, while 1 C. coli was pan-susceptible except for tylosin. Single-nucleotide polymorphisms concordance varied widely, with differences of up to 13,375 single-nucleotide polymorphisms compared to the reference Campylobacter isolates, highlighting genetic divergence among comparative genomes. This study contributes to a deeper understanding of the molecular epidemiology of Campylobacter spp. in Thai chicken production systems.

Abstract
Foodborne infections with antimicrobial-resistant Campylobacter spp. remain an important public health concern. Publicly available data collected by the National Antimicrobial Resistance Monitoring System for Enteric Bacteria related to antimicrobial resistance (AMR) in Campylobacter spp. isolated from broiler chickens and turkeys at the slaughterhouse level across the United States between 2013 and 2021 were analysed. A total of 1,899 chicken-origin (1,031 Campylobacter coli (C. coli) and 868 Campylobacter jejuni (C. jejuni)) and 798 turkey-origin (673 C. coli and 123 C. jejuni) isolates were assessed. Chicken isolates exhibited high resistance to tetracycline (43.65%), moderate resistance to ciprofloxacin (19.5%), and low resistance to clindamycin (4.32%) and azithromycin (3.84%). Turkey isolates exhibited very high resistance to tetracycline (69%) and high resistance to ciprofloxacin (39%). The probability of resistance to all tested antimicrobials, except for tetracycline, significantly decreased during the latter part of the study period. Turkey-origin Campylobacter isolates had higher odds of resistance to all antimicrobials than isolates from chickens. Compared to C. jejuni isolates, C. coli isolates had higher odds of resistance to all antimicrobials, except for ciprofloxacin. The study findings emphasize the need for poultry-type-specific strategies to address differences in AMR among Campylobacter isolates.

Abstract
BACKGROUND Early childhood enteric infection with Shigella/EIEC, enteroaggregative E. coli (EAEC), Campylobacter, and Giardia has been associated with reduced child growth, yet a recent randomized trial of antimicrobial therapy to reduce these infections did not improve growth outcomes. To interrogate this discrepancy, we measured the enteric infections from this study. METHODS We leveraged the Early Life Interventions for Childhood Growth and Development in Tanzania (ELICIT) trial, a randomized double-blind placebo-controlled trial of antimicrobial therapy with azithromycin and nitazoxanide provided quarterly to infants from 6 to 15 months of age. We tested 5,479 stool samples at time points across the study for 34 enteropathogens using quantitative PCR. RESULTS There was substantial carriage of enteropathogens in stool. Azithromycin administration led to reductions in Campylobacter jejuni/coli, enteroaggregative E. coli, and Shigella/EIEC (absolute risk difference ranged from -0.06 to 0.24) 2 weeks after treatment however there was no effect after 3 months. There was no difference in Giardia after nitazoxanide administration (ARR 0.03 at the 12 month administration). When examining the effect of azithromycin versus placebo on the subset of children infected with specific pathogens at the time of treatment, a small increase in weight-for-age Z score was seen only in those infected with Campylobacter jejuni/coli (0.10 Z score, 95% CI -0.01-0.20; length-for-age Z score 0.07, 95% CI -0.06-0.20). CONCLUSION The antimicrobial intervention of quarterly azithromycin plus or minus nitazoxanide led to only transient decreases in enteric infections with Shigella/EIEC, enteroaggregative E. coli (EAEC), Campylobacter, and Giardia. There was a trend towards improved growth in children infected with Campylobacter that received quarterly azithromycin.

Abstract
AIMS To evaluate the biofilm-forming capacity of thermotolerant Campylobacter (TC) strains from poultry production and to analyse the inhibitory capacity of Lactiplantibacillus plantarum LP5 against TC on different materials. METHODS AND RESULTS Biofilm-forming capacity by Campylobacter jejuni and Campylobacter coli was analysed by cell adhesion in polystyrene plates. TC were classified as non-biofilm-forming (NBF, 1.3%), weak biofilm-forming (WBF, 68.4%), moderate biofilm-forming (MBF, 27.6%), and strong biofilm-forming (SBF, 2.7%). The inhibitory capacity of L. plantarum LP5 against TC was tested on stainless-steel, nylon, aluminium, and glass disks (treated group) and compared with biofilm-forming TC (control group). Lactiplantibacillus plantarum LP5 was inoculated, and then TC. Biofilm was removed in both experimental groups and TC and LP5 bacterial counts were performed. The L. plantarum LP5 presence reduced the formation of TC biofilm (P < 0.001). The material type and strain category influenced biofilm formation, with stainless-steel and the SBF strain being the material and TC having the highest adhesion (P < 0.001). Lactiplantibacillus plantarum LP5 formed a similar biofilm on all materials (P = 0.823). CONCLUSIONS This trial showed very promising results; L. plantarum LP5 could be incorporated as a bio-protector of TC on different surfaces.

Abstract
Campylobacter species infections in immunocompromised patients have the potential to progress to bacteremia and other extra-intestinal diseases. There is a sparsity of robust data, including antibiotic susceptibility data for contemporary agents, upon which to base treatment decisions. Moreover, intrinsic antimicrobial resistance in Campylobacter spp. further limits treatment options. The current publication by Bonilla-Moreno et al. elaborates on this clinical dilemma through the development, treatment, and molecular investigation of the putative mechanisms of carbapenem resistance in an immunocompromised patient with Campylobacter coli bacteremia.

Abstract
Campylobacter growth kinetic parameters can be used to refine the sensitivity and efficiency of microbial growth-based methods. Therefore, the aim of this study was to construct growth curves for C. jejuni, C. coli, and C. lari in pure culture and calculate growth kinetics for each Campylobacter species in the same environmental conditions. Campylobacter jejuni, C. coli and C. lari were grown over 48 h and inoculated into 15 mL Hungate tubes (N = 3 trials per species; 5 biological replicates per trial; 3 species; 1 strain per species). Absorbance measurements were taken in 45 min intervals over 24 h. Optical density readings were plotted versus time to calculate growth kinetic parameters. C. jejuni exhibited the longest lag phase (p < 0.001) at 15 h 20 min ± 30 min, versus C. coli at 11 h 15 min ± 17 min, and C. lari at 9 h 27 min ± 15 min. The exponential phase duration was no longer than 5 h for all species, and doubling times were all less than 1h 30 min. The variation in growth kinetics for the three species of Campylobacter illustrates the importance of determining individual Campylobacter spp. growth responses for optimizing detection based on low bacterial levels. This study provides kinetics and estimates to define enrichment times necessary for low concentration Campylobacter detection.

Abstract
Turkeys are important sources of antimicrobial-resistant Campylobacter. A total of 1063 isolates were obtained from 293 turkey flocks across Canada between 2016 and 2021 to evaluate their antimicrobial resistance (AMR) prevalence, patterns, distribution, and association with antimicrobial use (AMU). A high proportion of C. jejuni and C. coli isolates were resistant to tetracyclines and fluoroquinolones, despite the very low use of these drugs. C. jejuni isolates had a higher probability of being resistant to tetracyclines than C. coli isolates. The chance of C. jejuni isolates being resistant to fluoroquinolones, macrolides, and lincosamides was lower compared to C. coli. Isolates from the western region had a higher probability of being resistant to fluoroquinolones than isolates from Ontario. Isolates from Ontario had higher odds of being resistant to tetracyclines than isolates from Quebec. No associations were noted between the resistance and use of the same antimicrobial, but the use of certain antimicrobial classes may have played a role in the maintenance of resistance in Campylobacter (fluoroquinolone resistance - bacitracin and streptogramin use, tetracycline resistance - flavophospholipids and streptogramins use, macrolide resistance - flavophospholipid use). Low-level multidrug-resistant Campylobacter was observed indicating a stable AMR in turkeys. This study provided insights aiding future AMU and AMR surveillance.

Abstract
Campylobacter bacteremia is an uncommon disease that mainly occurs in immunocompromised patients and is associated with antibiotic resistance, particularly in Campylobacter coli. We report a patient with persistent blood infection because of a multidrug-resistant (MDR) C. coli strain over a 3-month period. Through this period monotherapy with meropenem was associated with the development of resistance to it. Improving immunity status and a combined therapy for intestinal decolonization were useful to control persistent C. coli infection in this patient.

Abstract
Building on a previously developed workflow for rapid and sensitive pathogen detection by qPCR, this work has established a sample treatment strategy that produces consistent quantification efficiencies (QEs) for Campylobacter jejuni against a complex and highly variable sample matrix from a suburban river. The individual treatments most effective at minimizing the inhibitory effects of the sample matrix were pH buffering with HEPES (50 mM, pH 5.7) and addition of the surfactant Tween 20 (2% v/v). Unexpectedly, sample acidification (pH 4-5) resulting from the use of aged Tween 20 that had undergone partial hydrolysis, appeared to play a key role in enhancing QE. This effect could be replicated by direct pH adjustment with dilute hydrochloric acid and may be linked to the solubilization and removal of inhibitory particles at an acidic pH. While the effectiveness of each individual treatment method varied, a combined treatment of either HEPES buffer + Tween 20, or direct pH adjustment + Tween 20, consistently produced QEs of 60%-70% and up to 100%, respectively, over a sampling period of one year. The consistency and scalability of this workflow make it a suitable alternative to culture-based ISO methods for detecting Campylobacter spp.

Abstract
Campylobacter jejuni and coli are two main pathogenic species inducing diarrhoeal diseases in humans, which are responsible for the loss of 33 million lives each year. Current Campylobacter infections are mainly monitored by clinical surveillance which is often limited to individuals seeking treatment, resulting in under-reporting of disease prevalence and untimely indicators of community outbreaks. Wastewater-based epidemiology (WBE) has been developed and employed for the wastewater surveillance of pathogenic viruses and bacteria. Monitoring the temporal changes of pathogen concentration in wastewater allows the early detection of disease outbreaks in a community. However, studies investigating the WBE back-estimation of Campylobacter spp. are rare. Essential factors including the analytical recovery efficiency, the decay rate, the effect of in-sewer transport, and the correlation between the wastewater concentration and the infections in communities are lacking to support wastewater surveillance. This study carried out experiments to investigate the recovery of Campylobacter jejuni and coli from wastewater and the decay under different simulated sewer reactor conditions. It was found that the recovery of Campylobacter spp. from wastewater varied with their concentrations in wastewater and depended on the detection limit of quantification methods. The concentration reduction of Campylobacter. jejuni and coli in sewers followed a two-phase reduction model, and the faster concentration reduction during the first phase is mainly due to their partitioning onto sewer biofilms. The total decay of Campylobacter. jejuni and coli varied in different types of sewer reactors, i.e. rising main vs. gravity sewer. In addition, the sensitivity analysis for WBE back-estimation of Campylobacter suggested that the first-phase decay rate constant (k1) and the turning time point (t1) are determining factors and their impacts increased with the hydraulic retention time of wastewater.

Abstract
The natural environment and water are among the sources of Campylobacter jejuni and Campylobacter coli. A limited number of protocols exist for the isolation of campylobacters in poorly filterable water. Therefore, the goal of our work was to find a more efficient method of Campylobacter isolation and detection from wastewater and surface water than the ISO standard. In the novel rapid culture method presented here, samples are centrifuged at high speed, and the resuspended pellet is inoculated on a filter, which is placed on Campylobacter selective mCCDA agar. The motile bacteria pass through the filter pores, and mCCDA agar suppresses the growth of background microbiota on behalf of campylobacters. This culture-based method is more efficient for the detection and isolation of Campylobacter jejuni and Campylobacter coli from poorly filterable water than the ISO 17995 standard. It also is less time-consuming, taking only 72 h and comprising three steps, while the ISO standard method requires five or six steps and 144-192 h. This novel culture method, based on high-speed centrifugation, bacterial motility, and selective cultivation conditions, can be used for the detection and isolation of various bacteria from water samples.

Abstract
INTRODUCTION Spontaneous bacterial peritonitis (SBP) is a fatal infection in patients. It often happens in patients with cirrhosis, cancer or diabetes, and is caused mostly by Enterobacteriaceae. Here we report a rare case of SBP caused by Campylobacter Coli (C coli) infection, which was identified promptly by the matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and received adequate therapy sooner after. PATIENT CONCERNS In the present study, we reported a 46-year-old male with alcoholic liver cirrhosis (Child-Pugh class C) and type 2 diabetes mellitus presented with a 1-day history of fever and abdominal pain. DIAGNOSIS Based on the clinical examinations, the patient was diagnosed with SBP and the pathogen was quickly identified as C coli by the matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), a rare causative pathogen of SBP. INTERVENTIONS The patient received a 10-day antibiotic treatment with Ciprofloxacin 400 mg every 12 hours, and recovered successfully. OUTCOMES The patient had a successful treatment outcome. CONCLUSION The study demonstrated a new possible infectious cause of SBP by C Coli, which was rarely seen in liver cirrhosis but mostly found in immunocompromised patients. Thus, it might raise an idea of microorganism screening of broader types that might also induce SBP for immunocompromised patients.

Abstract
We herein report a case of recurrent Campylobacter coli bacteremia in a 37-year-old Japanese man with X-linked agammaglobulinemia (XLA). The patient experienced seven episodes of C. coli bacteremia over one year, with an erythematous rash intermittently emerged on the lower limbs. Although hospitalization for intravenous treatment was repeatedly recommended, he obstinately declined it. Following long-term oral antibiotic treatment with tebipenem and faropenem for the persistent infection, C. coli showed elevated minimum inhibitory concentrations to meropenem, a key drug for severe campylobacteriosis. Physicians should note that the overuse of antibiotics can lead to the emergence of carbapenem-non-susceptible Campylobacter strains.

Abstract
Campylobacter is the most common causative agent of human bacterial gastroenteritis and is frequently found in surface water, where it indicates recent contamination with animal faeces, sewage effluent, and agricultural run-off. The contribution of different animal reservoirs to surface water contamination with Campylobacter is largely unknown. In the Netherlands, the massive poultry culling to control the 2003 avian influenza epidemic coincided with a 44-50% reduction in human campylobacteriosis cases in the culling areas, suggesting substantial environment-mediated spread of poultry-borne Campylobacter. We inferred the origin of surface water Campylobacter jejuni and Campylobacter coli strains in Luxembourg and the Netherlands, as defined by multilocus sequence typing, by comparison to strains from poultry, pigs, ruminants, and wild birds, using the asymmetric island model for source attribution. Most Luxembourgish water strains were attributed to wild birds (61.0%), followed by poultry (18.8%), ruminants (15.9%), and pigs (4.3%); whereas the Dutch water strains were mainly attributed to poultry (51.7%), wild birds (37.3%), ruminants (9.8%), and pigs (1.2%). Attributions varied over seasons and surface water types, and geographical variation in the relative contribution of poultry correlated with the magnitude of poultry production at either the national or provincial level, suggesting that environmental dissemination of Campylobacter from poultry farms and slaughterhouses can be substantial in poultry-rich regions.

Abstract
This work focused on the isolation of thermophilic Campylobacter spp. in samples obtained from dog droppings. There were 135 samples collected and examined from both clinically healthy and diseased dogs from households, clinics, rehabilitation centres and dog shelters in eastern Slovakia. The isolation of the Campylobacter spp. was achieved by the use of combined selective cultivation methods, followed by confirmation and species identification of the isolates using the PCR method.The overall prevalence of Campylobacter in dogs was 30.4%. Statistically significant differences were recorded (P < 0.05) within the age groups of all dogs examined: 40.6% of the older dogs (> or = 1 year) tested positive, compared to 19.7% of the younger ones (< 1 year). There was no significant difference in relation to dog gender. The most frequently isolated species was Campylobacter (C.) jejuni, present in 51.2% of all positive samples. Campylobacter coli was present in 9.8% of the samples. The remaining positive samples (39%) were confirmed as C upsaliensis, based on phenotypic traits. The highest prevalence of Campylobacter was found in samples from shelters (50%) and the lowest in those from households (11.5%), with samples from rehabilitation centres (42.3%) and clinics (18.8%) coming in second and third place.The high prevalence of Campylobacter confirms the hypothesis that dogs, mainly the ones kept in groups, are a source of Campylobacter spp. Further investigation is required to determine to what extent infected dogs may be a potential source of infection in humans.

Abstract
A family outbreak of gastroenteritis caused by Campylobacter coli occurred in May 2006 in Bielsko-Biala, in the south of Poland. Four members of a family had non-bloody diarrhea and abdominal cramps. C. coli were isolated in three of the four patients. PFGE and PCR-RFLP-flaA patterns confirmed the link between cases, showing the usefulness of these methods in outbreak investigation. At the same time, the epidemiological and environmental investigations of this outbreak were very limited and did not provide enough evidence to identify the source of infection, and thus to support the hypothesis formulated by the local epidemiologist. It is necessary to improve surveillance of campylobacteriosis mainly by multidisciplinary training of epidemiologists, microbiologists and general practitioners.

Abstract
Campylobacter coli (C. coli) is a rare pathogen of bacteremia, but in immunocompromised hosts, C. coli occasionally causes bacteremia which can be refractory to antibiotic treatment. We report a case of C. coli bacteremia in a patient with X-linked agammaglobulinemia. Bacteremia relapsed repeatedly in spite of treatment with combined intravenous antibiotics. C. coli was observed in the biopsy specimens from the intestinal mucosa, suggesting intestinal carriage and reservoir of recurring infection. The addition of oral kamamycin with intravenous antibiotics was successful in eradicating C. coli from the blood and intestine.

Abstract
BACKGROUND Campylobacterje junilcoli is one of the most commonly identified bacterial causes of acute gastroenteritis worldwide. In Nigeria, it has been reported in the northern part of the country, extensive work has also been done in the south-west leaving behind the middle-belt of the country. OBJECTIVE To determine the role of Campylobacter jejunilcoli as an agent of diarrhoea in the middle-belt of Nigeria. DESIGN A prospective case control study. SETTING University of Ilorin Teaching Hospital (UITH), private hospitals and primary health centers all in Ilorin, Nigeria. SUBJECTS Three hundred and six children with diarrhoea and 100 without diarrhoea were randomly selected. MAIN OUTCOME MEASURES Isolation of Campylobacter jejuni/coli from stool samples. Biological characteristics of the isolates. RESULTS Twenty five (8.2%) of the patients and none of the controls had the organism. Campylobacter jejuni and C. coli were 56% and 44% respectively. All the isolates were susceptible to erythromycin and ciprofloxacin. None of the isolates harboured plasmids. CONCLUSION C. jejunil coli is an important diarrhoea agent in our geographic environment, further characterisation is desired of these local strains.

Abstract
A case-control study was conducted in Sweden to study risk factors for domestically acquired Campylobacter jejuni/coli infections among children aged less than 6 y. A total of 126 cases, reported to the national surveillance system were recruited over 1 y. Controls, selected from the population register, were matched to the cases by age, gender, place of residence and time of infection of the case. Information was gathered by posted questionnaires. Two separate conditional regression models were developed including and excluding 'protective' factors. Two of the factors significantly associated with Campylobacter infection were water-related: having a well in the household (OR=2.6) and drinking water from a lake/river (OR=7.4; 6.0). Other exposures associated with increased risk were: having a dog (OR=8.4; 3.8) and eating grilled meat (OR=5.5; 2.1). Drinking unpasteurized milk was borderline significant in 1 model (OR=3.7). Eating sausage was protective (OR=0.05). Eating chicken was not a significant risk. Exposures such as eating grilled meat and drinking water from a lake or a river were more common in the warm months, a factor that may partly explain the observed seasonality. The authors suggest that differences between risk factors across studies may reflect geographical and age-specific differences in the sources of infection.

OBJECTIVES To estimate the incidence of postinfectious joint complaints after Campylobacter jejuni/coli enteritis compared with enteritis caused by enterotoxigenic E coli (ETEC). To compare gastrointestinal symptoms, antibiotic treatment, and antibody levels among patients with and without joint symptoms. METHOD Questionnaires were sent to 210 consecutive patients with Campylobacter infection and an equal number of patients with E coli (ETEC). Blood samples for anti-Campylobacter antibodies were collected after two weeks, three months, six months, and two years. RESULTS Twenty seven of 173 (16%) patients with Campylobacter and 10/177 (6%) with E coli (ETEC) reported joint symptoms (p=0.004). In the Campylobacter group duration of diarrhoea was a median of 13 days for patients with arthralgia and seven days for those without joint pain (p=0.0058). Patients with E coli had diarrhoea of longer duration than patients infected with Campylobacter (14 days v seven days; p=0.0005). E coli patients had fewer gastrointestinal symptoms than Campylobacter patients (p=0.0001). Fifty nine per cent of Campylobacter patients with joint pain had received antibiotic treatment because of enteritis compared with 26% with enteritis only (p=0.03). Campylobacter species and serotypes were equally distributed in both groups and there was no difference in anti-Campylobacter antibody levels between the groups. CONCLUSION There was a significantly increased risk of developing joint symptoms after contracting Campylobacter infection compared with E coli. Campylobacter patients with joint pain had more severe gastrointestinal symptoms and longer duration of diarrhoea. Antibiotic treatment does not seem to prevent reactive joint symptoms. Levels of anti-Campylobacter antibodies were the same in both groups.

Abstract
In May 1995, the Scientific Institute of Public Health was informed of an outbreak of gastrointestinal illness in a congregational school in the Brussels area. The field investigation identified 24 cases with mild to severe gastrointestinal and general symptoms of acute bacterial enterocolitis. Campylobacter coli was detected in the stools of 5 patients. A retrospective cohort study suggested that a mixed salad (containing ham and feta cheese) was the probable source of infection, but the route of contamination remained unknown. The rapid investigation of such episodes of collective foodborne infections is essential for the implementation of adequate control measures.

Abstract
A cross sectional study on the prevalence of Campylobacter jejuni/coli and its possible aetiologic role in childhood diarrhoea in Yaounde was undertaken in 272 children presenting with diarrhoea and 157 age matched controls from April 1989 to October 1990. Stool cultures were performed according to standard techniques for Campylobacter jejuni/coli shigella and salmonella species. Rotavirus was detected using a latex agglutination test. Campylobacter jejuni/coli was isolated from 21 (7,7 pc) of 272 patients with diarrhoea and five of 157 (3,2 pc) controls (p > 0.05), all aged zero to four years old. Shigella and salmonella species were cultured from 2,2 pc and 1,1 pc of 272 patients respectively while rotavirus antigen was detected in 19,6 pc of 204 patients. Twenty eight pc of children with Campylobacter enteritis were exposed to chickens while 23,8 regularly drank water from streams which probably were contaminated. Our results indicate a high prevalence of campylobacter enteritis in children living in Yaounde and also suggest that a high rate of carriage of Campylobacter jejuni/coli could exist in children zero to four years without diarrhoeal illness. to four years without diarrhoeal illness.

Abstract
The genus Campylobacter has become increasingly recognised as the cause of various infections. Campylobacter jejuni and C coli cause acute gastroenteritis in man all over the world. C jejuni enteritis can lead to bacteraemia, but its actual incidence remains unknown. Seven cases of bacteraemia caused by C jejuni or C coli are reported, from the blood of seven patients: five immune deficient adults; a newborn baby; and a patient who had had abdominal surgery. Patients who develop diarrhoea as a result of Campylobacter infection are at risk of bacteraemia thereafter.

Abstract
To determine the role of animals as possible sources for human infection with Campylobacter jejuni/coli, 218 human cases of Campylobacter enteritis diagnosed among members of Group Health Cooperative of Puget Sound, King County, Washington, from April 1982 through September 1983 were compared with 526 controls, randomly selected from Group Health Cooperative members. All subjects were questioned regarding animal exposures one week prior to illness (cases) or interview (controls). There was no increase in risk for C. jejuni/coli enteritis associated with contact with various animals. However, exposure to diarrheic animals was associated with a fourfold increase in the risk of C. jejuni/coli enteritis (odds ratio = 4.3, 95% confidence interval (CI) 1.9-9.7). Adjustment for potential confounding factors by logistic regression analysis yielded an odds ratio of 3.3 (95% CI 1.2-7.5) associated with such exposure. An estimated 6.3% of cases of C. jejuni/coli enteritis was attributed to exposure to diarrheic animals.

Abstract
We report the case of a 71-year old male patient with a chronic lymphoid leukaemia of 10 years' duration who abruptly suffered deterioration of this general condition and haematological disturbances suggesting worsening of this blood disease (Richter's syndrome). Blood cultures demonstrated a Campylobacter coli septicaemia. Treatment with antibiotics resulted in a return to the previous clinical and biological situation. The various visceral manifestation of the infection are discussed.

Abstract
Campylobacter jejuni and C. coli are the most commonly reported bacterial causes of enteritis in man in the United Kingdom. The reported incidence of campylobacter infection varies with place and time. Its epidemiology differs from that of salmonella: campylobacters do not multiply on food, secondary spread is rare, and infections peak at the end of May (salmonellas peak in July). Known sources of infection include poultry, milk, water, pets and other domestic animals. Campylobacters are widespread in the environment, and in domestic and wild birds and mammals. About 10% of infections reported in the UK are acquired abroad. The application of preventive measures can be effective in reducing the incidence of infection and its not inconsiderable financial burden.

Abstract
Antibiotic susceptibility testing and plasmid screening of 50 local isolates of Campylobacter coli and Campylobacter jejuni were done. All isolates were sensitive to ofloxacin but were resistant to ampicillin, cloxacillin, penicillin, streptomycin and aztreonam. A large number of isolates were sensitive to nalidixic acid (96%), ceftriaxone (96%) and chloramphenicol (86%). It is noteworthy that nine (18%) of the isolates were resistant to each of erythromycin, 15 (30%) were found to harbour plasmid DNA ranging in sizes from 2.0 to 45 megadalton. Resistance to tetracycline in one isolate was associated with the carriage of a 45-megadalton plasmid.

Abstract
Campylobacter species are known to cause infectious abortion in domestic animals. In humans, Campylobacter are an important cause of enteritis, an occasional cause of systemic infection and have had a rare association with abortion and perinatal infection. A case history of spontaneous abortion, at 26 weeks' duration, associated with maternal bacteraemia, due to Campylobacter coli is presented. Transmission, pathogenesis, treatment, and the need for further investigation are discussed.

Abstract
Campylobacter coli strains of bovine and avian origin were inoculated into the mammary gland of mice. A bovine strain isolated from a case of mastitis produced gross and histological changes in most of the glands; one bovine and one avian faecal isolate did not. Histologically, lesions were characterised by neutrophil infiltration in the alveolar spaces and necrosis and oedema in the interalveolar tissue. On bacteriological examination, the bovine mastitis strain could be isolated from most of the glands, but neither of the faecal strains. The mouse, therefore, appears to provide a convenient model for studying campylobacter mastitis.

Abstract
The clinical efficacy, safety and usefulness of Rokitamycin (RKM), a new macrolide antibiotic, were compared with those of Ofloxacin (OFLX) for the treatment of Campylobacter enteritis by a double blind method. The daily dose level of RKM or OFLX was 600 mg. They were orally administered in three divided doses for 5 days. Of 223 cases studied, 106 cases were diagnosed as Campylobacter enteritis. Ninety cases (RKM group: 50, OFLX group: 40) except for 16 excluded or drop-out cases were analysed. There was no significant difference between the two groups in any background factors. The effectiveness and usefulness was evaluated in 88 cases (RKM group: 48, OFLX group: 40). The results obtained were as follows: 1. In a total of 82 strains of Campylobacter jejuni/coli (RKM group: 42, OFLX group: 40), the bacteriological efficacy rate of RKM (95.2%) was superior to that of OFLX (70.0%) with a significant difference (p = 0.006). 2. In 76 symptomatic patients (RKM group: 42, OFLX group: 34) on the day of the beginning of drug administration, the clinical efficacy rate was 97.6% in the RKM group and 85.3% in the OFLX group with no significant difference between the two groups. 3. In 88 evaluable patients, the global clinical efficacy rate of RKM (95.8%) was superior to that of OFLX (67.5%) with a significant difference (p = 0.001). 4. Side effect was observed in 1 (1.9%) of the 54 patients in the RKM group and none of the 44 patients in the OFLX group. Slightly abnormal laboratory findings were seen in 4 (10.8%) of the 37 patients treated with RKM and 3 (9.7%) of the 31 patients treated with OFLX, but there was no significant difference between the two groups. 5. In 88 evaluable patients, the clinical usefulness of RKM (91.7%) was superior to that of OFLX (67.5%) with a significant difference (p = 0.01). From these results, RKM is considered to be a very useful agent for the treatment of Campylobacter enteritis.

Abstract
Rokitamycin, a newly developed macrolide, was administered to a total of 107 cases, 16 years old or more, in order to evaluate its clinical efficacy, safety and usefulness on Campylobacter enteritis. Daily dosage of 600 mg of rokitamycin was administered orally in three divided doses for 5 days. Bacteriological and clinical efficacies were judged by the attending doctors from the evaluation criteria made by the committee and from the days required for improvement of diarrhea, defervescence and so on, respectively. Antibacterial activities against the isolates were tested of rokitamycin (RKM), erythromycin (EM), josamycin (JM) and ofloxacin (OFLX). The results were as follows; 41 symptomatic patients and 5 carriers were evaluated. Clinical efficacy (n = 41) was 100% (excellent; 34.1%, good; 65.9%). Bacteriological efficacy (n = 41) was 97.6%. Eight of the 9 cases with consecutive stool cultures were free of the bacteria on and after one day of the drug administration. Clinical usefulness (n = 46) was 97.8%. Slight epigastric pain was seen in only one as a side effect. The items of abnormal laboratory findings were 4 elevated GPT and/or GOT and one increased number of WBC in 4 cases. MIC90 of RKM, EM, JM and OFLX against 41 clinical isolates of C. jejuni were 1.56, 3.13, 3.13 and 0.78 micrograms/ml, respectively. Rokitamycin was considered clinically useful to treat Campylobacter enteritis.

Abstract
Sequential stool cultures submitted for routine culture were screened for the presence of CDC group DF-3. Of 690 specimens, 11 (1.6%) yielded moderate to heavy growth of DF-3. Information on the 11 patients from whom these specimens were obtained showed that 4 had a history of prolonged diarrheal disease that resolved after specific therapy to eradicate DF-3, while for the other 7 patients no clear role could be established. Microbiological characterization of the stool isolates and 10 CDC strains of DF-3 suggested the presence of two subtypes within the group. Antibiotic susceptibility studies showed DF-3 to be relatively resistant to a wide variety of antibiotics.
