RESUMEN

Goats fulfil a central role in food and nutritional security across Africa with over half of households owning or rearing goats in rural areas. However, goat performance is poor and mortality high. This study assessed the nutritional quality of commonly used feeds and proposes feed-baskets to enhance goat nutrition and health. Feeds were collected from 11 areas within the Central District of Botswana, and macronutrient analyses were conducted, including crude protein, fibre fractions, ash, and metabolizable energy (ME). Forage nutrition was compared across seasons and soil types. Additionally, seasonal supplementation trials were conducted to evaluate consumption rates of various supplements, including crop residues, pellets, Lablab purpureus, and Dichrostachys cinerea. Each supplement was provided ad libitum for a 24-h period, and consumption rates determined. Findings revealed significant differences in nutrition among various feed sources, across seasons, and in relation to soil types (p < 0.001). Consumption rates of supplements were higher during the dry season, possibly due to reduced forage availability. Supplement consumption rates varied across supplement type, with crop residues accounting for approximately 1% of dry matter intake, compared to up to 45% for pellets, 13% for L. purpureus, and 15% for D. cinerea. While wet season feed baskets exhibited higher ME values compared to dry-season feed-baskets, the relative impact of supplementation was more pronounced during the dry season. These results highlight the potential for optimizing goat diets through improved grazing and browsing management, especially during the reduced nutritional availability in the dry season in Botswana. Such diet optimisation may improve goat health and productivity, which may positively impact the food and financial security of smallholders by providing both increased yields and increased resilience. Importantly, rural communities can experience some of the lowest food security levels in the region. The interventions explored in this study utilise natural capital, often freely available, which can be deployed through existing husbandry systems, potentially making them accessible and practical to smallholders.

RESUMEN

We evaluated the relationship between individual and herd GIN infection level, nutrition, production performance and anemia parameters in a tropical farm context. Fifty-four female goats were monitored to assess their body condition score (BCS, nutritional status indicator), live weight (LW) and LW gain (LWG, both used as production level indicators), FAMACHA© and hematocrit (HT, both used as anemia indicators). Goats browsed for 4 h in a tropical forest and received balanced feed and chopped grass. The eggs per gram of feces (EPG) indicated the GIN burden, with fecal samples obtained at 7:00 (AM) and 15:00 h (PM.) from each goat at six sampling points during the study. The variables and their relationship with GIN burdens were analyzed using Kruskall-Wallis, ANOVA and Friedman tests and Spearman correlations. The fecal samples obtained in the AM and PM can be equally representative of parasitic burdens (similar and highly correlated). However, the EPG of individual goats from periods of 30 days apart can be considered independent. The BCS and LWG varied between sampling times (p < 0.05), whereas EPG, LW and HT did not (p > 0.05). The GIN burden was negatively correlated with HT and BCS (-0.21, p = 0.01 for each one). The individual pattern of infection demonstrates the true impact of GINs on their hosts. Additionally, feeding and nutritional status may present important variations influencing the performance of the goats more than the impact of GINs under the farm conditions of the present study. However, GIN infection contributed to the variation in goat health and productivity in this tropical farm.

RESUMEN

Smallholder goat production plays a major role in rural livelihoods and food security in Malawi, but suffers from drastic and unpredictable production losses. While goat production is closely linked to small-scale local markets for slaughter and butchering, the perspectives of butchers and their potential as a source of animal health information are largely untapped. Butchers can provide insights into goat health status at slaughter as well as issues that go unseen before slaughter, such as the presence of indigestible foreign bodies (IFBs). IFBs include solid materials such as plastics and hardware (metals, stones, and other hard objects) that cause foreign body syndrome and can lead to impaction, oedema, malnutrition, and death. To estimate the presence of IFBs, 150 market stand butchers were surveyed across five districts in Malawi, focusing on a distinction between hardware and single-use plastics, which are still widely present in Malawi despite bans on production. Most butchers found plastic IFBs (80.7%), with over half (56.7%) reporting plastic IFBs recently among the past five slaughters. Hardware IFBs were less common, reported by 45.3% of butchers. While some butchers commented on the impact of IFBs on meat quality metrics ex-post, the majority observed no differences. While butchers unanimously considered health to be an important characteristic when sourcing goats, 70.7% consider injury status to be less important or not important. Overall, this study highlights the issue of anthropogenic waste pollution on goat production in Malawi and demonstrates the potential for the surveillance of goat health at market.

RESUMEN

BACKGROUND: Veterinary diagnostics aid intervention strategies, track zoonoses, and direct selective breeding programs in livestock. In ruminants, gastrointestinal nematode (GIN) parasites are a major cause of production losses, but morphologically similar species limit our understanding of how specific GIN co-infections impact health in resource-limited settings. To estimate the presence and relative abundance of GINs and other helminths at the species level, we sought to develop a low-cost and low-resource molecular toolkit applied to goats from rural Malawi smallholdings. METHODS: Goats were subjected to health scoring and faecal sampling on smallholdings in Lilongwe district, Malawi. Infection intensities were estimated by faecal nematode egg counts with a faecal subsample desiccated for DNA analysis. Two DNA extraction methods were tested (low-resource magbead kit vs high-resource spin-column kit), with resulting DNA screened by endpoint polymerase chain reaction (PCR), semi-quantitative PCR, quantitative PCR (qPCR), high-resolution melt curve analysis (HRMC), and 'nemabiome' internal transcribed spacer 2 (ITS-2) amplicon sequencing. RESULTS: Both DNA isolation methods yielded comparable results despite poorer DNA purity and faecal contaminant carryover from the low-resource magbead method. GINs were detected in 100% of samples regardless of infection intensity. Co-infections with GINs and coccidia (Eimeria spp.) were present in most goats, with GIN populations dominated by Haemonchus contortus, Trichostrongylus colubriformis, Trichostrongylus axei, and Oesophagostomum columbianum. Both multiplex PCR and qPCR were highly predictive of GIN species proportions obtained using nemabiome amplicon sequencing; however, HRMC was less reliable than PCR in predicting the presence of particular species. CONCLUSIONS: These data represent the first 'nemabiome' sequencing of GINs from naturally infected smallholder goats in Africa and show the variable nature of GIN co-infections between individual animals. A similar level of granularity was detected by semi-quantitative PCR methods, which provided an accurate summary of species composition. Assessing GIN co-infections is therefore possible using cost-efficient low-resource DNA extraction and PCR approaches that can increase the capacity of molecular resources in areas where sequencing platforms are not available; and also open the door to affordable molecular GIN diagnostics. Given the diverse nature of infections in livestock and wildlife, these approaches have potential for disease surveillance in other areas.

RESUMEN

Introduction: Developmental dysplasia of the hip (DDH) is the cause of 2.6-9.1% of all total hip prostheses implanted at any age and constitutes a challenge in revision surgeries. Objective: To present a case of severe acetabular dysplasia managed by the Stoppa-type approach. The Case: We report a case of a 26-year-old male patient with DDH initially treated with total hip replacement and then diagnosed with aseptic loosening (Paprosky 3A). Using a modified Stoppa approach; acetabular augmentation and bone autograft attached with endopelvic reconstruction plates were performed. Two years after the procedure our patient is asymptomatic, has no restrictions on his daily living activities, and is very satisfied with the result. Conclusions: The Stoppa approach was very useful for the endopelvic reconstruction of the acetabular roof, so it may be an option to treat severe acetabular defects. Level of evidence: IV.

RESUMEN

We evaluated the effect of browsing experience, nutritional quality and secondary compounds of forage resources, and the interaction between these factors on the selection and intake of goats in a cafeteria trial. Twelve juvenile Criollo goats from 7 to 9 months of age, weighing 22 ± 3 kg, were divided into two groups: (a) browser goats group (n = 6, BG), and (b) naïve goats group (n = 6, NG), formed according to their previous browsing experience (with and without, respectively). Animals were housed in individual pens. The cafeteria experiment lasted 21 days considering pen adaptation, foliage adaptation, and measurements, which included the selection index (SI) of experimental forage resources (Chesson's alpha) and their dry matter intake (DMI/Kg0.75), using a multiple Latin square design. Furthermore, correlation and regression analyses were used to assess the relationship between the aforementioned factors. The NG did not show any selection pattern, while the BG selected Piscidia piscipula and Senegalia gaumeri (p = 0.0002). The BG consumed smaller amounts of secondary compounds compared to NG (p = 0.0001). In the BG, the flavonoids affected negatively their selection (R2 = 97.51, p = 0.0001), while the DMI was affected by in vitro DM digestibility and flavonoids (R2 = 99.85; p = 0.0001). For the NG, the crude protein and organic matter contents were associated with DMI, but none had a significant relationship with SI. The BG selected and consumed forages with suitable nutritional quality avoiding those with high content of secondary compounds such as flavonoids. Conversely, NG did not show a clear pattern for their selection or intake.

RESUMEN

Climate change is causing detrimental changes in living organisms, including pathogens. This review aimed to determine how climate change has impacted livestock system management, and consequently, what factors influenced the gastrointestinal nematodes epidemiology in small ruminants under tropical conditions. The latter is orientated to find out the possible solutions responding to climate change adverse effects. Climate factors that affect the patterns of transmission of gastrointestinal parasites of domesticated ruminants are reviewed. Climate change has modified the behavior of several animal species, including parasites. For this reason, new control methods are required for controlling parasitic infections in livestock animals. After a pertinent literature analysis, conclusions and perspectives of control are given.

RESUMEN

PURPOSE: Some agroindustrial by-products could be used as nutraceutical materials for small ruminants helping with their nutrition while controlling their gastrointestinal nematodes. This study evaluated the potential in vitro nutraceutical value of pod husks and leaves of three varieties of Theobroma cacao using two Haemonchus contortus isolates with different polyphenol susceptibility. METHODS: Leaves and husks from three T. cacao varieties (AZT, CAL and CEY) were evaluated for their bromatological composition, in vitro dry matter digestibility and polyphenol content. Acetone:water extracts (70:30) of each plant variety were evaluated using the egg hatch and larval exsheathment inhibition tests, using two isolates (FESC and PARAISO) of H. contortus. Effective concentrations 50% (EC50) were determined for both tests. The role of polyphenols was confirmed using polyvinylpolypyrrolidone. L3 exposed to CAL leaf extract were submitted to transmission electron microscopy. RESULTS: Both plant materials showed a good nutritional value to complement protein-rich diets for small ruminants. Extracts inhibited exsheathment of H. contortus L3 more effectively than the egg hatching, and the leaf extracts were more active than husk extracts in the L3 exsheathment inhibition. The FESC isolate was more sensitive to extracts. Polyphenols blocked exsheathment inhibition of leaf extracts. Structural damage was observed in the sheath and muscles of L3 exposed to CAL leaf extracts. CONCLUSION: The two T. cacao materials tested showed their potential to be used as ruminant feeds. Extracts affected H. contortus by blocking L3 exsheathment, particularly with the leaf extracts. The in vivo nutraceutical value should be confirmed in small ruminants.

RESUMEN

Resumen La leishmaniasis es una enfermedad con una alta incidencia en el ser humano, que puede ser controlada, pero como los tratamientos tienen efectos secundarios importantes se han realizado estudios de diversas plantas con el fin de encontrar compuestos con actividad antileishmaniásica que presenten pocos efectos nocivos para el ser humano. El presente estudio consistió en realizar un tamizaje fitoquímico de la planta, para identificar la presencia de cumarinas, terpenos, triterpenos y azúcares reductores. El objetivo fue encontrar componentes químicos puros con actividad contra el parásito Leishmania sp. Por tal razón se purificaron los compuestos: trans-Z-alfabisaboleno y el Safrol, a los que se les realizaron pruebas del efecto anti parasitario que presentaron un CI50 de 50.0 µg/mL y 0.0 µg/mL, respectivamente. Además, se discute la importancia de estos nuevos hallazgos. El compuesto mayoritario presente en los aceites esenciales (Safrol) no es el componente que presentó la actividad. Es importante realizar estudios sobre su proyección en el tratamiento de la leishmaniasis.

Abstract The leishmaniosis disease incidence is high in tropical regions, and its current treatment has shown severe secondary effects. Considering this problem, many studies have focused on plants, looking for chemical components that have anti-leishmanial activity, and are free of adverse effects for human beings. The purpose of this work was to find a chemical component with this kind of activity in Piper auritum. In a phytochemical screening of this plant, we found some cumarins, terpens, triterpens and reducing sugars; and later, we identified the components trans-Z-α-bisabolene epoxide and Safrol. The first component presented a CI50 of 50.0 µg/mL of anti-Leishmania activity. The Safrol, which is the major component of the essential oils of this plant, did not show antiparasitic activity. These results are discussed considering treatment of leishmaniasis. Rev. Biol. Trop. 66(2): 826-835. Epub 2018 June 01.

RESUMEN

Los linfomas constituyen un grupo diverso de neoplasias malignas, que se originan del sistema linfático(1). Aproximadamente el 85% se agrupan dentro de los denominados Linfomas No Hodgkin (LNH). Los LNH constituyen un numeroso grupo de linfomas derivados de la transformación neoplásica de los linfocitos B, T y Células NK, provenientes de diversas zonas que comprometen los folículos linfáticos en los nódulos linfáticos o en el sistema linfoide extranodal(2). Las localizaciones extra ganglionares primarias representan más de 10% de los casos y los sitios más frecuentes comprenden estómago, intestino delgado, orofaringe, piel, hígado y cerebro; además de otras bastante raras como ano, corazón, músculos y encías. Los linfomas testiculares primarios son muy raros, representan aproximadamente el 5% de todas las neoplasias testiculares malignas, menos del 1% de los LNH y el 4% de los LNH extra nodales(3). Esta neoplasia constituye el tumor maligno testicular más frecuente en sujetos ancianos. La presentación clínica típica es una masa testicular unilateral acompañada en ocasiones de hidrocele y dolor agudo escrotal. A continuación presentamos un caso que requirió de la participación de múltiples especialidades de nuestra institución para un manejo conjunto y finalmente el paciente falleció(AU)

The lymphomas constitute a diverse group of malignant neoplasms, which originate from the lymphatic system(1). Approximately 85% are grouped into the so-called Non-Hodgkin's Lymphomas (NHL). NHL are a large group of lymphomas derived from the neoplastic transformation of B, T and NK cells of different areas with involvement of lymphatic follicles in the lymph nodes or the extranodal lymphoid system(2). The primary extraganglionic sites represent more than 10% of the cases and the most frequent sites include stomach, small intestine, oropharynx, skin, liver and brain; others, quite rare, are anus, heart, muscles and gums.Primary testicular lymphomas are extremely rare, accounting for approximately 5% of all malignant testicular neoplasms, less than 1% of NHL and 4% of extranodal NHL(3). This neoplasm constitutes the most frequent testicular malignant tumor in elderly subjects. The typical clinical presentation is a unilateral testicular mass, sometimes accompanied by hydrocele and acute scrotal pain. We present a case which required the participation of multiple specialties of our institution for management but the patient finally died(AU)

RESUMEN

Current knowledge of the behavior of heavy quadricycles under impact is still very poor. One of the most significant causes is the lack of energy absorption in the vehicle frame or its steel chassis structure. For this reason, special steels (with yield stresses equal to or greater than 350 MPa) are commonly used in the automotive industry due to their great strain hardening properties along the plastic zone, which allows good energy absorption under impact. This paper presents a proposal for a steel quadricycle energy absorption system which meets the percentages of energy absorption for conventional vehicles systems. This proposal is validated by explicit dynamics simulation, which will define the whole problem mathematically and verify behavior under impact at speeds of 40 km/h and 56 km/h using the finite element method (FEM). One of the main consequences of this study is that this FEM-based methodology can tackle high nonlinear problems like this one with success, avoiding the need to carry out experimental tests, with consequent economical savings since experimental tests are very expensive. Finally, the conclusions from this innovative research work are given.

RESUMEN

Leishmaniosis is an important human disease very difficult to treat. For this reason, many researchers in the world have been look- ing for anti-leishmanial chemical components present in several plant species. In Costa Rica, since no studies have been done in this field, this work aimed at the search of active chemical components in local plants that may have an activity against Leishmania sp. A total of 67 plants were selected from the Alberto Manuel Brenes Biological Reserve (REBAMB). For these collected plants, fresh or dried hidroalcoholic extracts of root, stem, mature or young leaves, flowers, and immature or mature fruits, were prepared under conventional methods. All extracts were tested for their effect against a strain of Leishmania (OCR with known characteristics). Firstly, by presumptive tests, we selected only those with some activity, and then, more specific studies were done to determine the IC50 in µg/mL; a promising plant was considered only if at least one of its parts presented an IC50 < 100 µg/mL. Under this parameter, the following active plants were obtained and their lowest and highest IC50 obtained values presented (µg/mL): Bocconia frutescens (0.6 and 66.7), Clematis dioica (27.5 and 44.4), Cordia megalantha (80.0), Eugenia austin-smithi (90.6), Guarea bullata (98.8), Guateria tonduzii (44.4 and 66.3), Mikania holwayana (45.0 and 95.6), Nectandra membranacea (44.5 and 58.6), Neurolaena lobata (25.0 and 100.0), Persea povedae (76.9), Piper auritum (60.0), Rollinia pittieri (43.1), Solanum arboreum (25.8 and 72.5), Tetrorchidiumn eurphyllum (53.8 and 95.0), Witheringia solanacea (15.9 and 98.1) and Zanthoxylum juniperinum (23.4 and 97.5). Although the parasitic effect of fresh or dried extracts were almost similar, the fresh material slightly showed better results. That anti-parasitic effect occurred in one or more than four parts of the plant. Most of the active extracts did not produce lysis and aglutination which indicates a low toxicity. Since the species studied are different from those analyzed by other authors, we discuss the importance of these new findings, in relation to the new scientific knowledge, and the possible use of these plants as a leishmaniosis treatment.
