ABSTRACT

The One Health concept represents the inseparability of human, animal, and environmental health through a unified view of health care. This article addressed the topic of public health policies from the One Health perspective, demonstrating its inclusion in various health agendas such as emerging and reemerging infectious diseases, basic sanitation, mental health, chronic non-communicable diseases, interpersonal violence, and food safety. The results showed that the application of the One Health concept to the development and implementation of policies is associated with a growing need to involve transdisciplinary teams for solving complex problems to improve communication and to ensure the relevance and acceptability of public policies, thus guaranteeing governance. According to the principle of efficiency, the government must be aware of the evolution of technical knowledge and should use the One Health approach to improve the efficacy of already existing systems. We, therefore, conducted this review to contextualize current knowledge in this topic which is becoming an essential tool for public health policy-makers and practitioners around the world promoting a reflection on the importance of multiprofessional articulation in the implementation of intersectoral public health policies.

ABSTRACT

Dermatophytosis, a zoonotic disease, is caused by fungi of three main genera, namely, Micropsorum, Trichophyton, and Epidermophyton. Specific lesions of dermatophyte infections are localized in the face, legs, and/or tail. Skin lesions in infected animals demonstrate localized alopecia, erythema, and crust, which are more commonly known as ringworm. Factors that affect dermatophytosis include the dermatophyte species; virulence factors of the agent; and the immune status, age, and sex of the host. High levels of cortisol and pro-inflammatory cytokines have also been reported to play an important role in dermatophyte infection. This review aims to explore and understand factors that affect dermatophyte infection with an emphasis on the prevalence, clinical signs, pathogenesis, immune response, and the roles of cortisol and cytokines in companion animals infected by a dermatophyte.

Keywords: clinical signs, cortisol, cytokine, dermatophytosis, immune response, pathogenesis.

ABSTRACT

Background and Aim: Numerous studies have found benefits of omega-3 polyunsaturated fatty acids (PUFAs), namely, for eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in dogs. The objective of the present study was to assess the efficacy of dietary inclusion of equal amounts of omega-3 FAs in phospholipid (PL) from krill meal to triglyceride structure from fish oil to increase the omega-3 FA profile in red blood cells (RBCs) in dogs.

Materials and Methods: Ten adult Alaskan Huskies of both genders were supplemented with daily 1.7 g EPA and DHA from krill meal for 6 weeks, while another ten dogs received 1.7 g EPA and DHA from fish oil. FA and omega-3 index measurements of the two groups were taken after 0, 3, and 6 weeks for comparison.

Results: It was mainly the EPA levels that increased in the krill meal group (from 1.84% to 4.42%) compared to the fish oil group (from 1.90% to 2.46%) (p<0.001), which drove the group differences in the omega-3 index. This resulted in the krill meal group having a mean omega-3 index increase from 3.9 at baseline to 6.3%, which was significantly greater than the increase from 3.9% to 4.7% observed in the fish oil group (p<0.001). Concomitantly, omega-6 PUFAs, such as arachidonic acid and linoleic acid, were reduced in RBC membranes and the omega-6 to omega-3 ratio was significantly more reduced in the krill meal compared to the fish oil group.

Conclusion: The results showed that krill meal supplementation was associated with a reduction of omega-6 PUFAs, which compensated for the increased omega-3 index, suggesting that PLs are efficient delivery molecules of omega-3 PUFAs.

Keywords: dog, fish oil, krill meal, omega-3 index, phospholipids, triglycerides.

ABSTRACT

Aim: This study aimed at examined the presence of coliform bacteria in private wells and boreholes (BH) in peri-urban areas of Makurdi, Benue State, Nigeria, using the approaches of most probable number (MPN) index and coliform count.

Materials and Methods: Seven hundred and sixty-eight water samples were randomly collected during a 1-year period from non-cased wells, burn brick cased wells (BBW), concrete cased wells, and BH in four locations; A, B, C, and D during the wet and dry seasons. One liter of water was obtained from each well at every visit to the four sites, and eight water samples were collected from each visit. The samples were analyzed using multiple tube fermentation methods and pour plate techniques to determine the MPN of coliform/100 ml of water, reading from the MPN statistics table.

Results: One-way analysis of variance statistics was applied using Duncan's new multiple range test to separate the means where there was a significant difference. The result revealed that the MPN index and total coliform counts in all the wells in the locations were above the World Health Organization (WHO) permissible limit for potable water. The highest MPN index of 54.807 was recorded in Location A and followed by 42.679 in Location B. The MPN index in Locations C and D was 36.740 and 30.943, respectively. There was significantly (p=0.000) higher total coliform count in the wet season (41.48±7.09) than in the dry season (38.33±2.83).

Conclusion: This study shows the presence of coliform bacteria isolates in all the wells and BH that exceeded the WHO permissible limits for drinking water. The water from these sources is unsafe for drinking except after dosing with appropriate germicides. Sensitization of the population on the actions they can take to make the water safe for domestic use is suggested.

ABSTRACT

Aim: The purpose of the present study was to evaluate the effects of Beauveria bassiana (Hypocreales) inoculum on plant growth, volatile constituents, and tick repellency of the extracts of Tulbaghia violacea (Amaryllidaceae).

Materials and Methods: Eight-week-old potted seedlings of T. violacea were each inoculated with conidia of B. bassiana (strain SM3) suspended at a concentration of 1×106 conidia mL–1. Tissue colonization by fungal conidia was assessed after 3 weeks. Plant growth, volatile constituents, and tick repellency were assessed after 12 weeks post-treatment.

Results: B. bassiana conidia successfully colonized leaf and root tissues of T. violacea. The growth of fungal hyphae out of the leaf and root sections occurred in 75% and 91.6% of plants, respectively. Inoculation of the plants with B. bassiana significantly (p<0.05) influenced root length and plant height but did not have substantial effects on weights and leaf number of T. violacea. While the fungus did not have significant effects on overall number of the volatile chemical constituents, significant variations in the quantity (area ratio) were observed in at least four compounds that were detected. In the tick repellency bioassay, high concentration (20 w/v%) of acetone extract from fungus-exposed plants produced the least repellent effect on Rhipicephalus appendiculatus larvae (Ixodidae), while at lower concentrations (5 w/v% and 10 w/v%) of acetone extracts of T. violacea, tick repellent activity of the extract of the fungus treatment was significantly improved and was comparable to commercial N,N-Diethyl-m-toluamide and the other treatments.

Conclusion: Experimental fungal inoculation positively influenced plant growth in height and root length and tick (R. appendiculatus) repellency of acetone extracts of T. violacea at a concentration of 10 w/v% compared to the control treatment.

Keywords: Beauveria bassiana, fungal endophyte, secondary metabolites, tick repellency, tick toxicity, Tulbaghia violacea.

ABSTRACT

Aim: The aims of this study were first to estimate calcification in the esophagus and abomasum of cows and second to quantify its appearance with increasing age using histopathological and immunohistochemical techniques.

Materials and Methods: Esophageal and abomasal samples from 24 healthy cows (Bos taurus) were collected. Hematoxylin and eosin, alizarin red, and von Kossa stains were used for histopathological analysis. Histopathological changes were confirmed with immunohistochemical staining, followed by digital image analysis.

Results: Histological findings revealed the esophagus and abomasum wall comprised four fundamental layers, the mucosa, submucosa, muscularis, and serosa or adventitia. At 1 year old, calcification was beginning to appear as fine diffused points in mucosa, submucosa, and muscularis of both esophagus and abomasum, appearing as small spots at 2 years old. With advancing age in all animals, this calcification began to appear as medium spots spread throughout all wall layers of these organs at 3 years old. By 4 years old, calcification had evolved into large dark foci spread substantially throughout the tunica submucosa and tunica muscularis. Immunohistochemical results exhibited positive immunoreaction to calcium salts in the esophagus and abomasum layers in all animals, which increased with age.

Conclusion: The current study concluded that calcification is a pathological event appearing spontaneously in various types of soft tissue, significantly increasing with age, either because of hypercalcemia and hyperphosphatemia or secondary to other diseases.
