- Antibiotic-resistant bacteria are a major concern in the healthcare of today, especially the increasing number of gram-negative bacteria producing -lactamases such as extended-spectrum -lactamases (ESBLs). However, little is known about the relationship of ESBL producers in humans and domestic and wild birds, especially in a low-income setting. Therefore, we studied the fecal carriage of ESBL-producing Escherichia coli and Klebsiella pneumoniae in healthy humans, poultry, and wild birds in the vicinity of Leon, Nicaragua. Three hundred fecal samples were collected during December 2012 from humans (n=100), poultry (n=100) and wild birds (n=100). The samples were examined for ESBL-producing E. coli and K. pneumoniae, revealing the prevalence of 27% in humans, 13% in poultry, and 8% in wild birds. Further characterization of the ESBL-producing isolates was performed through polymerase chain reaction (PCR) (NDM, CTX-M), epidemiological typing (ERIC2-PCR), multilocus sequence typing, and sequencing. ESBL producers harbored bla(CTX-M-2), bla(CTX-M-15), bla(CTX-M-22), and bla(CTX-M-3) genotypes. The bla(CTX-M-15) constituted the absolute majority of ESBL genes among all samples. ERIC-PCR demonstrated highly related E. coli clones among humans, poultry, and wild birds. Clinically relevant E. coli clone ST648 was found in humans and poultry. There is a shared pool of bla(CTX-M) genes between humans and domesticated and wild birds in Nicaragua, and the results suggest shared clones of ESBL-producing E. coli. The study adds to the notion that wild birds and poultry can pick up antibiotic-resistant bacteria of human origin and function as a melting pot of resistance. Structured surveillance programs of antimicrobial resistance and a more regulated prescription of antibiotics are warranted in Nicaragua.

- Antibiotic resistance in avian bacterial pathogens is a common problem in the Bangladesh poultry industry. The aim of the present study was to provide information on the present status of antibiotic resistance patterns in avian pathogenic Escherichia coli in Bangladesh. Of 279 dead or sick poultry of different ages, 101 pathogenic E. coli strains isolated from broilers and layer hens with colibacillosis infections were screened to determine phenotypic expression of antimicrobial resistance against 13 antibiotics used in both veterinary and human medicine in Bangladesh. Of 101 pathogenic E. coli isolates, more than 55% were resistant to at least one or more of the tested compounds, and 36.6% of the isolates showed multiple-drug-resistant phenotypes. The most common resistances observed were against tetracycline (45.5%), trimethoprim-sulphamethoxazole (26.7%), nalidixic acid (25.7%), ampicillin (25.7%), and streptomycin (20.8%). Resistance to ciprofloxacin (12.9%), chlormaphenicol (8.9%), nitrofurantoin (2%), and gentamicin (2%) was also observed, and none of the isolates were resistant to tigecycline as well as extended spectrum beta-lactamase (ESBL) producers. One isolate was resistant to cefuroxime (1%), cefadroxil (1%), and mecillinam (1%) but was not an ESBL producer. Resistance rates, although significant in Bangladeshi isolates, were found to be lower than those reported for avian isolates from the Republic of Korea and clinical, avian, and environmental isolates from Bangladesh. The high level of antibiotic resistance in avian pathogens from Bangladesh is worrisome and indicates that widespread use of antibiotics as feed additives for growth promotion and disease prevention could have negative implications for human and animal health and the environment.

- The presence and frequency of multiresistant bacteria in wild birds act as indicators of the environmental contamination of antibiotic resistance. To explore the rate of contamination mediated by Escherichia coli, 150 fecal samples from the brown-headed gull (Chroicocephalus brunnicephalus) and 8 water samples from the Bay of Bengal area were collected, cultured, and tested for antibiotic susceptibility. Special attention was paid to extended-spectrum beta-lactamase (ESBL)-producing isolates, which were further characterized genetically. Antibiotic resistance was found in 42.3% (36/85) of the E. coli isolates and multidrug resistance in 11.8%. Isolates from the area with a higher human activity were more resistant than those from an area with a lower level of activity. Most frequent was resistance to ampicillin (29.4%), followed by trimethoprim-sulfamethoxazole (24.7%) and quinolones (22.4%). Carriage of ESBL-producing E. coli was relatively high (17.3%) in the gulls, whereas no ESBL producers were found in the water. All ESBL-producing E. coli isolates, but one, carried blaCTX-M-15 or blaCTX-M-15-like genes. A blaCTX-M-14-like enzyme was found as an exception. Gulls from two different colonies shared E. coli clones and harbored the clinically relevant sequence types ST10, ST48, and ST131. The high frequency of antibiotic resistance and ESBL production among E. coli isolates from gulls indicates that the environmental contamination of antibiotic resistance has already gone far on the coastlines of the Bay of Bengal. Considering the limited control over the antibiotic consumption and waste from human activities in Bangladesh, there is no easy solution in sight.

- Media portrayal of the abysmal state of nutrition in Indian slums on regional TV in late 2011, an outraged judge signing off committees to monitor the situation, a grant for international research cooperation, a media collective, a law firm and seven students signing up for a course on community knowledge building converged to form the events leading to this chapter.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to enhance our understanding of intra-organizational trust in public organizations by studying interpersonal trust in both vertical and horizontal relationships from a bidirectional perspective. Previous research has focused on trust at a single level of analysis, ignoring influences from other organizational levels, which has led to gaps in our understanding of trust. In addition, few studies take a bidirectional perspective where a trustor is simultaneously a trustee and vice versa. Through a case study, we contributed to filling this gap by studying the antecedents of trust - ability, benevolence and integrity.

- This paper investigates the role of networks when emerging-economy firms enter into advanced- economy markets. More specifically, it focuses on how advanced-economy market supplier networks are created by the emerging-economy firm to legitimate it vis-á-vis advanced-economy customers. The purpose of the paper is to examine how emerging-economy firms establish supplier networks in advanced-economy markets in order to gain legitimacy with customers in other advanced-economy markets. The paper thereby highlights a different role of networks in internationalisation than what is portrayed in previous research and illustrates this through two case studies. The supplier networks in advanced economies are used to gain knowledge but also reputation, and thus deals with the liability of outsidership beyond what is described in previous research. The construct of a supplier network to reach a customer network points at two different networks and the connectivity between in them as a means for an emerging-economy firm to become accepted.
