Antimicrobials in small-scale urban pig farming in a lower middle-income country - arbitrary use and high resistance levels.

ABSTRACT: Administration of antimicrobials to food-producing animals is regarded as a major contributor to the overall emergence of resistance in bacteria worldwide. However, few data are available on global antimicrobial use and resistance (AMR) in livestock, especially from low- and middle-income countries.We conducted a structured survey of 91 small-scale pig farms in the urban and peri-urban areas of Phnom Penh, Cambodia, to assess the farmers' knowledge, attitudes and practices related to antimicrobial use in their pig production. Commensal Escherichia coli was isolated from three healthy pigs from each farm (n?=?261) and susceptibility testing was performed against 14 antimicrobials, using broth microdilution. Univariable logistic regression and generalized linear mixed models were used to investigate potential associations between farm characteristics, management factors and resistance to different types of antimicrobials.We found a widespread and arbitrary use of antimicrobials, often based on the farmer's own judgment. Around 66% of the farmers reported frequently self-adjusting treatment duration and dosage, and 45% had not heard about the term 'antimicrobial resistance'. The antimicrobials most commonly mentioned or kept by the farmers were amoxicillin, tylosin, gentamicin and colistin. Around 37% used a feed concentrate that contained antimicrobials, while antimicrobials for humans were used as a last-line treatment by 10% of the farmers. Commensal E. coli exhibited high prevalence of resistance to several antimicrobials considered to be of critical importance for human medicine, including ampicillin, ciprofloxacin and colistin, and multidrug-resistance was found in 79% of the samples. Higher prevalence of resistance was observed on farms that administered prophylactic antimicrobials and on farms that treated the entire group or herd in the event of disease.The widespread and arbitrary use of antimicrobials in pig farming in Cambodia is highly worrisome. Overall, farmers had a low awareness of the risks and consequences related to antimicrobial use and AMR. The results presented in this study confirm the hypothesis that non-rational use of antimicrobials results in higher prevalence of AMR and highlight the need for professional animal health systems that involve medically rational use of antimicrobials in emerging economies such as Cambodia.

Project description:BackgroundThe COVID-19 pandemic catalyzed the adoption of telerehabilitation in various health care settings. However, there was neither a preexisting national guideline in the Philippines nor an internationally agreed upon standard for telerehabilitation. The literature lacks nationwide studies documenting how physiatrists perceived and experienced telerehabilitation during the pandemic.ObjectiveTo determine the perceptions and experiences of physiatrists in the Philippines regarding telerehabilitation.DesignOnline survey originally developed by the authors with inputs from local experts in telehealth or telerehabilitation.SettingNationwide, involving board-certified physiatrists practicing in the Philippines.ParticipantsFellows of the Philippine Academy of Rehabilitation Medicine (PARM) (N = 259) with Internet access.Main outcome measuresSelf-reported telerehabilitation knowledge, skills, and experience; key concerns; preferred clients, service offerings, and methods (technology, duration, charging).ResultsThe respondents (n = 161; 62.2% response rate) had a mean age of 48.1 ± 9.6 years, were mostly female (57.8%), and mostly practiced in private hospitals and urban settings. The majority reported inadequate telerehabilitation knowledge (61.5%), skills (58.4%), and experience (72.1%). The most common sources of telerehabilitation knowledge were colleagues (52.8%), PARM (51.6%), and telemedicine-related websites (41.6%). Most of the respondents preferred to conduct telerehabilitation with former patients over new ones and prescribe telerehabilitation programs for physical, occupational, psychological, and speech-language therapy but not for swallowing therapy. Videoconferencing was the most common telerehabilitation method. More than half of the respondents charged lesser fees for telerehabilitation compared to in-person consultations. Although the majority recognized the need for telerehabilitation, their key concerns included the lack of thorough patient examination and medicolegal liability issues.ConclusionDespite their limited baseline knowledge, skills, and experience regarding telerehabilitation, many physiatrists in the Philippines learned to adopt this service delivery method during the pandemic. Their perceptions and experiences could be used in formulating practice-based guidelines and strategies to improve the conduct of telerehabilitation in the country.

Project description:Japanese encephalitis (JE) is endemic in Cambodia, but circulation of JE virus (JEV) among domestic pigs has previously only been studied in the southern part of the country. The main purpose of this study was to determine the seroprevalence of JEV antibodies in smallholder pigs held in rural areas of Kampong Thom, Preah Vihear, Ratanakiri, and Stung Treng provinces, northeastern Cambodia. Another purpose was to identify possible associations between serologic status and other factors, such as reproductive disorders, and to investigate the farmers' knowledge of mosquito-borne diseases and use of preventive measures. In October 2019, 139 households were visited throughout the study area, and 242 pigs were sampled for blood. The sera were analysed with ELISA for JEV antibodies. Household representatives were interviewed, and data were recorded for each sampled pig. The apparent seroprevalence was 89.1% in pigs between 3 and 6 months of age, and 100% in pigs over 6 months of age. In total, 93.0% of the pigs tested positive. Province appeared to be the only factor significantly associated with serologic status (p < 0.001). Almost all (97.8%) respondents knew that mosquitos could transmit diseases, and 70.5% had heard of JE. However, only one respondent knew that JEV is transmitted to people through mosquito bites. Very few respondents knew that pigs can become infected with JEV, and no one knew that mosquitos transmit the virus. All families used some sort of mosquito protection for themselves, but only 15.1% protected their pigs from mosquito bites. The children were vaccinated against JE in 93 households, while adults only were vaccinated in eight households. The results suggest that JEV transmission is intense in northeastern Cambodia, and that people's knowledge about the transmission route of JEV and the role of pigs in the transmission cycle is low. Fortunately, people are well aware of mosquito-borne diseases in general and use mosquito protection, and many children are vaccinated against JE. Nonetheless, it is important that national vaccination is continued, and that people-especially in rural areas where pigs are commonly kept-are educated on the ecology and transmission of JEV.
