ABSTRACT

Background and Aim: The information about the health problems interaction between animal health, ecosystems, and human health that the "One Health (OH)" concept is becoming more complex. This study focused on OH information in Thailand to develop guidelines for establishing a "One Health Information Management (OHIM)" system by drafting the structure of an OH information strategic plan.

Materials and Methods: A mixed methods approach was used and included questionnaires, interviews, focus groups, and observations in agencies across the country to gather evidence about actions relating to the OH concept, such as the Memorandum of Agreements between the Ministry of Public Health and eight main agencies.

Results: The study concentrated on the key issue that understanding the OH concept is difficult, as the environment and human health sectors include less knowledge of this concept than the animal health sector. Further, there are concerns about the comprehension of OH concepts, and high-level information management and data storage relating to OH, including medicine, cattle, wild animal, environment, and environmental resource management. Data from OH researchers and publicly accessible government data are less integrated and inconsistently managed across agencies.

Conclusion: The study of OHIM strategic development should consist of four important points: (1) Clarity in the OH concept, (2) OH staff development, (3) development of an OHIM data network and innovation, and (4) research and academic development, and global OHIM academic exchange. All of these points will lead to health system reforms to support social well-being.

ABSTRACT

Background and Aim: Acute hepatopancreatic necrosis disease (AHPND) is a severe disease in shrimp farms and adversely affected the shrimp industry of Vietnam. So far, the study on risk factors associated with AHPND outbreaks is limited. The objective of this study was to determine the potential risk factors of AHPND at the shrimp farm level in Bac Lieu Province, Vietnam.

Materials and Methods: Real-time-Polymerase chain reaction was used to analyze data collected from an active surveillance program of shrimp farms in 2017 in the Vinh Tien and Vinh Lac villages, Vinh Thinh commune, Hoa Binh district in Bac Lieu Province, Vietnam. The matched case-control study selected 20 cases and 20 control farms from 134 shrimp farms. In 2018, face-to-face interviews using structured questionnaires were conducted with the farmers of these selected farms.

Results: Of the 59 studied variables, seven had p≤0.2 based on bivariate analyses. The results of multivariable analysis showed that the presence of fish-eating birds on shrimp farms was a significant association with AHPND (odds ratio=8, p=0.049).

Conclusion: To reduce the effect of AHPND, farmers should apply effective methods to manage wild animals such as using a grid or net to cover the pond, combined with improved biosecurity.

ABSTRACT

Background and Aim: Balantidiasis, caused by Balantidium coli (syn. Neobalantidium coli or B. coli), represents a neglected parasitic infection of zoonotic significance affecting a variety of hosts, including domestic pigs that are the main reservoir. B. coli has a direct life cycle with a fecal-oral route transmission that occurs mainly by the ingestion of food and water contaminated with cysts. The ingestion of meat contaminated during inappropriate slaughtering processes may represent a new potential route of transmission. Only a few studies have investigated the prevalence of B. coli in domestic pigs in Italy, despite its high prevalence and zoonotic significance. This study aimed to improve the knowledge on B. coli prevalence in domestic swine reared both in intensive and "en plein air" breeding systems in the south of Italy.

Materials and Methods: The infection rate of B. coli in pigs bred in 15 different pig farms and regularly slaughtered in South Italy, in the Calabria region, was investigated. From 2017 to 2019, 177 terminal parts of the rectums of pigs, of which 91 commercial hybrids and 86 autochthonous (Nero Calabrese), reared, respectively, in intensive and "en plein air" breeding system, were tested for parasite detection. After the slaughtering, the terminal part of the rectum was sampled and transported to the laboratories and immediately processed. For the detection of trophozoites, fresh smears of feces were examined at light microscopy. Moreover, flotation was performed using a sodium chloride solution, then smears of feces were dispersed on microscope slides and examined at light microscopy. The observed parasites were identified at the species level using morphological characteristics.

Results: B. coli was detected in a total of 83 (i.e., 46.89%) pigs, with a significantly higher prevalence (p<0.0001) found in commercial hybrid (i.e., 59/91-64.84%) pigs rather than in autochthonous ones (i.e., 24/86-27.91%). It follows that the infection was more common in pigs reared in the intensive breeding system than in "en plein air" ones (p<0.0001). The infection prevalence was higher in males than in females and lower in elder animals than in younger ones (p=0.012 and p<0.0001, respectively).

Conclusion: The breeding system is likely the main discriminant for the parasite spread as well as the hygienic condition of the farms. Good manufacturing and hygiene practices along the food production chain are crucial in preventing human balantidiasis transmission by meat consumption. The high B. coli prevalence, the wide spectrum of host species, and its zoonotic significance push toward a greater public interest.

ABSTRACT

Background and Aim: Canine parvovirus (CPV) is the most important cause of mortality in dogs in many parts of the world. Clinical cases exhibit characteristic signs, including foul-smelling bloody diarrhea, vomiting, fever, and dehydration. This study assessed field and vaccine variants of parvovirus in the Chattogram metropolitan area, Bangladesh. The investigation also aimed to identify risk factors for this disease. This research is the first to identify the presence of CPV in Bangladesh through molecular examination.

Materials and Methods: From October to December 2019, a total of 100 dogs were included in the study. Rectal swabs were taken from all dogs. Twenty dogs showed clinical signs of parvovirus. All clinically affected animals along with 20 randomly selected healthy dogs were tested using amplification refractory mutation system (ARMS)-polymerase chain reaction (PCR) to identify variants from the samples. Logistic regression model analysis was performed to determine the possible risk factors for CPV.

Results: ARMS-PCR showed the presence of all three variants, CPV2a, CPV2b, and CPV2c, in clinically ill dogs, and vaccines available in the study area showed either CPV2a or CPV2b strain. The CPV2c variants showed a higher incidence than the other variants. All apparently healthy animals tested were molecularly negative. Multivariable logistic regression model (generalized linear mixed model) indicated that exotic breeds were 3.83 times more likely to be infected by CPV than local breeds. Furthermore, dogs reared in semi-intensive and extensive management systems were 3.64 and 3.79 times more likely to be infected, respectively, than those reared in an intensive management system.

Conclusion: These findings provide practitioners and pet owners information on the occurrence of different variants and help design effective prevention strategies for CPV infection.

ABSTRACT

Background and Aim: Mesenchymal stem cells (MSCs), which have multi-lineage differentiation potentials, are a promising source for regenerative medicine. However, the focus of study of MSCs is shifting from the characterization of the differentiation potential to their secretion potential for cell transplantation. Tissue regeneration and the attenuation of immune responses are thought to be affected by the secretion of multiple growth factors and cytokines by MSCs. However, the secretion potential of MSCs profiling remains incompletely characterized. In this study, we focused on the secretion ability related and protein mRNA expression of dog adipose tissue-derived MSCs (AT-MSC), bone marrow (BM)-derived MSCs, and BM-derived mononuclear cells (BM-MNC).

Materials and Methods: Real-time polymerase chain reaction analyses revealed mRNA expression of nine growth factors and seven interleukins in these types of cells and three growth factors protein expression were determined using Enzyme-linked immunosorbent assay.

Results: For the BM-MNC growth factors, the mRNA expression of transforming growth factor-β (TGF-β) was the highest. For the BM-derived MSC (BM-MSC) and AT-MSC growth factors, the mRNA expression of vascular endothelial growth factor (VEGF) was highest. BM-MSCs and AT-MSCs showed similar expression profiles. In contrast, BM-MNCs showed unique expression profiles for hepatocyte growth factor and epidermal growth factor. The three types of cells showed a similar expression of TGF-β.

Conclusion: We conclude that expression of cytokine proteins and mRNAs suggests involvement in tissue repair and protection.

ABSTRACT

Background and Aim: Antimicrobial resistance (AMR) is a serious challenge to animal and human health worldwide. Therefore, this study aims to determine levels and patterns of AMR of Escherichia coli and Salmonella spp. strains isolated from poultry farms in Côte d'Ivoire.

Materials and Methods: A cross-sectional study was conducted in two districts of Côte d'Ivoire with high poultry production: Abidjan and Agnibilékrou. A total of 231 fecal samples were collected in 124 poultry farms in both districts. Enterobacteria were isolated and tested for susceptibility to 14 antimicrobial agents using the disk-diffusion method.

Results: A total of 212 E. coli and 36 Salmonella strains were isolated. In Abidjan, 139 collected samples generated 101 E. coli and 23 Salmonella strains, whereas in Agnibilékrou, 92 collected samples generated 111 E. coli and 13 Salmonella strains. Variable resistance levels were recorded for the antibiotics tested. The resistance prevalence of E. coli and Salmonella, respectively, was high: Doxycycline (98%/94%), sulfonamide (84%/86%), trimethoprim-sulfamethoxazole (80%/41%), and streptomycin (71%/52%). Average resistance rates were recorded for flumequine (38%/66%), ampicillin (49%/33%), amoxicillin (25%/44%), colistin (26%/2%), chloramphenicol (21%/2%), and gentamicin (4%/47%). The antibiotics least affected by resistance were cefuroxime (4%/5%), ceftriaxone (2%/0.00%), and nitrofurantoin (1%/0.00%).

Conclusion: In this study, it was observed that resistance to important antibiotics is emerging in poultry production in Côte d'Ivoire. Policies promoting the rational use of antibiotics should be implemented to manage antibiotic resistance in animal production.

ABSTRACT

Background and Aim: In rabies endemic area, dog vaccination is an effective way of controlling the disease in animals and humans if a minimum of 70% vaccination coverage is reached. This study aimed to identify dog demographics and household characteristics associated with dogs' vaccination against rabies in Ouagadougou, Burkina Faso.

Materials and Methods: A questionnaire was used to collect data from respondents with regard to their dogs' demographics and their household characteristics. Chi-square test and Fisher's exact test were performed to assess the association between explicative variables and the dogs' vaccination status.

Results: Overall, as per the findings of this study, it was determined that out of 424 dogs, 57.8% were reportedly vaccinated. The vaccination status was significantly associated with most of the household variables (e.g., gender of the respondent, age, level of education, main means of transportation, participation in a vaccination campaign, knowledge on rabies, and knowledge on dog vaccination) and the dogs' variables (breed of dog, dog origin, purpose for keeping, confinement status, and perceived behavior) (p<0.05). Moreover, only religion, type of housing, knowledge of rabies transmission modes, and dog sex were not significantly associated with vaccination status (p>0.05).

Conclusion: Our study generated informative data showing that animal health workers could develop effective rabies vaccination strategy planning by examining owned dog demographics and their husbandry practices in households.
