Abstract
Salmonella is a major foodborne pathogen and a leading cause of gastroenteritis in humans and animals. Salmonella is highly pathogenic and encompasses more than 2600 characterized serovars. The transmission of Salmonella to humans occurs through the farm-to-fork continuum and is commonly linked to the consumption of animal-derived food products. Among these sources, poultry and poultry products are primary contributors, followed by beef, pork, fish, and non-animal-derived food such as fruits and vegetables. While antibiotics constitute the primary treatment for salmonellosis, the emergence of antibiotic resistance and the rise of multidrug-resistant (MDR) Salmonella strains have highlighted the urgency of developing antibiotic alternatives. Effective infection management necessitates a comprehensive understanding of the pathogen's epidemiology and transmission dynamics. Therefore, this comprehensive review focuses on the epidemiology, sources of infection, risk factors, transmission dynamics, and the host range of Salmonella serotypes. This review also investigates the disease characteristics observed in both humans and animals, antibiotic resistance, pathogenesis, and potential strategies for treatment and control of salmonellosis, emphasizing the most recent antibiotic-alternative approaches for infection control.

Fesseha H, Kefelegn T, Mathewos M. Animal care professionals' practice towards zoonotic disease management and infection control practice in selected districts of Wolaita zone, Southern Ethiopia. Heliyon 2022; 8:e09485. [PMID: 35637673 PMCID: PMC9142852 DOI: 10.1016/j.heliyon.2022.e09485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 11/04/2021] [Accepted: 05/13/2022] [Indexed: 11/23/2022] Open
Abstract
Veterinary practices or activities expose professionals to occupational hazards, including infection with zoonotic diseases, during contact with animals. To assess animal care professionals' practice towards zoonotic disease management and infection control practices (ICPs) in selected areas of the Wolaita zone, a cross-sectional survey was conducted using a structured questionnaire survey. A total of 287 animal care professionals were registered by the Wolaita zone livestock and fishery office and working in nine different districts of the Wolaita zone. Of these, 135 animal care professionals working across nine different districts of the Wolaita zone were interviewed in the current study. The survey showed that about 55% (74/135) of respondents were animal health assistants, and about 84% (114/135) of the professionals were males. In terms of utilization of ICP, about 72% of professionals routinely wash their hands before eating and drinking in their workplace. However, approximately 7% of professionals sometimes eat or drink at the workplace. Additionally, almost 32% of the professionals always wash their hands between patient contacts. In the survey, approximately 49% of veterinarians said they sterilized and reused disposable needles. When dealing with an animal suspected of carrying a zoonotic infection, nearly 25% of experts isolate or quarantine diseased animals, and only about 25% of the experts remove their personal protective equipment (PPE) before interacting with other animals. Approximately 62% of responders said they used outwear (PPE) when carrying out surgery and 28% when performing a necropsy. Nearly 39% of veterinarians reported using gloves and gowns when assisting with parturition or handling conception products, and around 36% of practitioners utilized proper PPE when handling blood samples. Our findings show that the veterinary community in the Wolaita Zone's selected sites needs to be educated about ICPs regularly. A better understanding of the risk of zoonotic disease exposure, as well as alternatives for reducing this risk and liability problems, may encourage the use of infection control measures. Successful partnerships across multiple professional sectors should use a One Health approach that includes stakeholders from the human, animal, and environmental categories.

Abstract
BACKGROUND Veterinarians face the risk of contracting zoonotic pathogens. Infection prevention and control (IPC) guidelines stress the importance of proper hand hygiene and personal protective equipment (PPE) to prevent transmission of these pathogens. OBJECTIVES We aimed to assess how ambulatory livestock and equine veterinarians follow IPC guidelines, when working on farms and in stables. METHODS We studied hygiene practices of livestock and equine ambulatory veterinarians (n = 129) in Finland. A web-based questionnaire was used to obtain demographic information and information regarding hand-hygiene facilities and practices, use and cleaning of PPE and cleaning of medical equipment. RESULTS According to 66.9% of the respondents, hand-washing facilities were often adequate on livestock farms, but only 21.4% reported that this was the case in stables (p < .001). While 75.0% reported washing their hands or using hand sanitizer always before moving on to the next farm, only 42.5% reported doing this before moving on to the next stables (p < .001). Universal protective coat or coverall use was more common in livestock practice than in equine practice (91.6% vs. 27.7%, p < .001). Stethoscope cleaning was reported to happen less frequently than once a week by 30.0% of the respondents. CONCLUSIONS Finnish veterinarians' self-reported IPC adherence was far from uniform. IPC was more commonly followed in ambulatory livestock practice perhaps facilitated by better hand-washing facilities on farms than in stables. The study suggests that education of veterinarians is still needed and that hand-washing facilities need to be improved even in a high-income country.

Abstract
The COVID-19 pandemic has caused a widespread shortage of facemasks and other personal protective equipment in veterinary medicine without clear, research-based guidance on alternatives to FDA-certified disposable surgical masks. In the absence of detailed veterinary research, an in-depth review of the human medical literature was conducted to evaluate the viability of reusable, sterilizable cloth, medical textile, or other material alternatives that may be quickly manufactured and used by veterinarians. The results at the time of publication support the AVMA, CDC, and WHO recommendations to extend use, reuse, and resterilize facemasks before considering using a homemade facemask. Pending further research, or until and unless the FDA certifies a reusable homemade mask or design, the substitution of homemade masks for FDA-certified surgical masks should only be considered as a last resort. Most homemade masks are not suitable replacements for N95 FFRs. If a homemade facemask must be made, the following materials and testing guidelines are suggested:
- densely woven cotton fabric (≥270 thread count), medical textile, or other impermeable, breathable material that can be laundered and resterilized - make pleated or fitted pocket style facemasks to maximize fit - make masks with two sets of ties, not elastics, to endure laundering and autoclaving - internal wire or fabric tape may be used to mold masks over the nose - filter material should be designed for use near mucus membranes, such as facial tissue or paper towel - if possible, fit test homemade masks against an FDA-certified surgical mask as a control - if higher filtration efficiency is required, test according to the FDA Enforcement Policy for Face Masks and Respirators During the Coronavirus Disease (COVID-19) Public Health Emergency - Maintain enough masks to change as frequently as one would change disposable surgical masks to maintain appropriate hygiene.

Abstract
Hospital-associated infections, including those caused by zoonotic agents, represent an increasing concern in veterinary practice. Veterinarians and hospital staff are obligated and expected to provide education about and protection from transmission of pathogens among animal patients and between animal patients and human beings (eg, veterinary staff, volunteers, owners) who come into contact with infected animals. Patient management involves assessing risks of pathogen transmission, identification of animals either suspected of or proved to be infected with a transmissible infectious disease agent, and the implementation of measures that minimize the likelihood of transmission of the infectious agent.

Bergström K, Grönlund U. A pre- and post-intervention study of infection control in equine hospitals in Sweden. Acta Vet Scand 2014; 56:52. [PMID: 25146752 PMCID: PMC4236551 DOI: 10.1186/s13028-014-0052-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2014] [Accepted: 08/13/2014] [Indexed: 11/13/2022] Open
Abstract
Background Detection of nosocomial methicillin-resistant Staphylococcus aureus infections in horses in Sweden has increased attention on infection control (IC) in equine hospitals. This study established baseline data on IC programmes within such settings, evaluated compliance with some IC procedures before and after an education intervention, and examined barriers to compliance. The study was carried out between 2008 and 2011 in four Swedish equine hospitals. Data on current IC of each hospital, purchase data on hand sanitisers and disposable gloves per patient, and direct observations of compliance with procedures were monitored pre- and post-intervention. The intervention comprised a lecture on common IC and a review of each hospital’s current procedures. For comparison, retrospective purchase data were reviewed. A questionnaire on individual compliance, experiences and opinions of IC was issued to employees. Results Three hospitals completed the study, while the fourth reported its IC procedures and completed the questionnaire. Actual numbers of procedures, content and level of documentation differed among the hospitals. Similarities were poor or absent IC implementation strategy, lack of active surveillance of compliance with procedures and no monitoring of such as nosocomial infections. Among the hospitals which completed the study, two reported pre-intervention observation of compliance, while all three reported post-intervention observations. The purchase data showed trends for changes over time, although not uniformly related to the intervention. One hospital demonstrated a significant post-intervention increase in compliance with glove procedures, accompanied by a non-significant post-intervention increase in purchases figures. Compliance with dress code and personal appearance was high in all three hospitals (92-100%), while compliance with hand hygiene procedures was generally poorer. Barriers to compliance cited in the questionnaire (data from four hospitals) included insufficient supplies of hygiene products, lack of readily accessible places for cleaning, insufficient knowledge and high workload. Conclusions Potential for easily attainable improvements in IC, such as traceability of documents, implementation strategies and surveillance of efficacy, was revealed. Attention to hand hygiene implementation and improvement of logistics appeared important. Data on purchases per patient were readily available and therefore applicable for intra-hospital surveillance of IC trends over time.

Abstract
Millions of individuals are in contact with horses through occupational or recreational activities. Injuries from horses are responsible for over 100,000 emergency room visits each year in the United States. Although various types of traumatic injuries related to direct contact with horses are well described, roughly 3% to 4.5% of all reported injuries are due to bites by equines. The immediate injuries are commonly either blunt or penetrating trauma to local tissue; however, the bite exposure may also transmit a microbial agent of equine origin that can lead to a zoonotic infection. In almost all jurisdictions in the United States, animal bites are considered public health events and should be reported to the local health departments. Many animals can harbor many unusual zoonotic pathogens that both the individual health provider and public health officials much consider as they can adversely impact both the patient and the community health. This review focuses on those zoonoses that have been reported in the literature, including those that may in theory be transmitted from equine to human by direct inoculation or exposure to oral/nasal secretions from horses and other equine species.
