This study integrated accessibility and location-allocation models in geographic information systems as a proposed strategy to improve the spatial planning of public health services. To estimate accessibility, we modified two-step floating catchment area (2SFCA) model with different impedance function, Gaussian weight for competition among service sites, friction coefficient, distances along street network based on Dijkstra's algorithm by performing vectorial analysis. check accuracy...
Seven novel porcine parvoviruses (nPPVs) (PPV2 through PPV8) have been described, although their pathogenicity and possible effects on reproductive failure (PRF) are undefined. In this study, these nPPVs were assessed in gilts from Colombia; coinfections with PPV1, PCV2, PCV3, PCV4, PRRSV an association between the performance parameters (RPPs) sows determined. For this, 234 serum samples collected healthy 40 herds five Colombian regions, viruses detected via real-time PCR. The results...
Brazilian Spotted Fever (BSF), caused by the bacterium Rickettsia rickettsii, is tick-borne disease that generates largest number of human deaths in world. In Brazil, current increase BSF cases has been associated with presence and expansion capybaras Hydrochoerus hydrochaeris, which act as primary hosts for tick Amblyomma sculptum, vector R. rickettsii this area.
This study proposed the use of satellite hyperspectral imagery to support tick-borne infectious diseases surveillance based on monitoring variation in amplifier hosts food sources. To verify this strategy, we used data human rickettsiosis occurrences southeastern Brazil, region which emergence disease is associated with rising capybara population. Spatio-temporal analysis Monte Carlo simulations was identify risk areas and moderate-resolution increment expansion sugarcane crops, main source...
O abandono de animais é frequente e comum em toda América Latina, causando prejuízos nos âmbitos da saúde pública, social, ecológica, economia do bem-estar animal. Estão entre as principais causas animal: os problemas comportamentais dos animais, relacionados à falta espaço nas moradias, bem como o estilo vida proprietários, a informação sobre responsabilidades custos gerados pela guarda animais. É crescente número leis municipais brasileiras relacionadas ao animal, devido pressão setores...
There are a huge number of pathogens with multi-component transmission cycles, involving amplifier hosts, vectors or complex pathogen life cycles. These systems present challenges in terms modeling and policy development. A lethal tick-borne infectious disease, the Brazilian Spotted Fever (BSF), is relevant example that. The current increase human cases BSF has been associated presence expansion capybara Hydrochoerus hydrochaeris, host for agent Rickettsia rickettsii primary tick vector...
Bovine neosporosis is a parasitic disease with worldwide distribution that causes important economic losses. Because of the limited information on occurrence Neospora caninum infection in Colombia, this study aimed to determine seroprevalence and identify risk factors associated cattle Antioquia, which largest milk-producing state country. We collected 1,038 blood samples from Holstein, Jersey crossbred cows 31 farms. An epidemiologic questionnaire was given all owners. A commercial ELISA...
This study sought to investigate the presence of anti-Rickettsia spp. antibodies in georeferenced serum samples from equids across all regions state Goiás, while also presenting variables that indicate risk factors for circulation rickettsiae, and evaluating rickettsial DNA ticks collected surrounding environment municipalities Uruaçu Porangatu, located northern region state. A total 1156 equid provided by Goiás Agricultural Defense Agency (Agrodefesa) were analyzed against 4 Rickettsia...
Spotted fever illness caused by the tick-borne pathogen Rickettsia parkeri has emerged in Pampa biome southern Brazil, where tick Amblyomma tigrinum is implicated as main vector. Because domestic dogs are commonly parasitized A. tigrinum, this canid also a suitable sentinel for R. parkeri-associated spotted fever. Herein, we investigate rickettsial infection ticks, and small mammals natural reserve of Brazil. The ticks aureolatum Rhipicephalus sanguineus were collected from dogs. Molecular...
Abstract Experiences during gestation can alter the mother’s behavior and physiology, thereby potentially affecting behavioral physiological development of offspring. In livestock, one common challenge for pregnant animals is lameness: a multifactorial condition that causes pain, stress, resulting in poor welfare outcomes. Since maternal pain affect offspring development, we aimed to quantify response 142 piglets born from sows with different degrees lameness pregnancy. Gait scores 22...
Abstract Ticks of the Amblyomma maculatum (Ixodida Ixodidae) complex, cajennense complex and ovale are known to transmit various Rickettsia species in Colombia, but their exact distribution is unknown. We built several models based on current climate projected future changes using a maximum entropy approach. A total 314 records A. (65.9%; n = 207), (22.9%; 72), (11.1%; 35) were obtained. has Pacific, Caribbean Andean regions could be potentially found Amazon. Orinoco regions. mixtum can near...
Brazilian Spotted Fever (BSF) is an emerging and lethal disease in South America which basic reproduction number (R0) unknown. Calculating R0 for this crucial to design control interventions prevent human deaths. BSF endemic areas are related the presence of capybaras Hydrochoerus hydrochaeris, amplifier hosts Rickettsia rickettsii primary tick Amblyomma sculptum, main vector agent area. Because complexity its dynamics, we calculated system by constructing a next-generation matrix...
Background: routine practices such as biometrics, transportation and medical procedures are a source of stress to fish. The use anesthetics is recommended reduce undesirable effects stress, decreased feed intake even mortality -in critical cases. Objective: the aim this study was determine anesthetic efficacy eugenol benzocaine in juveniles red tilapia Oreochromis sp. Methods: thirty (Oreochromis sp.) were distributed groups 10 individuals follows; G1: (50 mg/L), G2: (100 mg/L) G3: mg/L)....
Bacterial genome sequencing has revealed a vast number of novel biosynthetic gene clusters (BGC) with potential to produce bioactive natural products. However, the biosynthesis secondary metabolites by bacteria is often silenced under laboratory conditions, limiting controlled expression Here we describe an integrated methodology for construction and screening elicited pre-fractionated library marine bacteria. In this pilot study, chemical elicitors were evaluated mimic environment induce...
The persistence of inflammatory processes in the myocardium varying degrees chronic Chagas heart disease has been poorly investigated. We hypothesized that edema could occur patients with chagasic cardiomyopathy and corresponds to myocardium. Eighty-two (CD) seropositive (64.6% females; age = 58.9 ± 9.9) without ischemic or conditions cause myocardial fibrosis dilation were considered. Late gadolinium enhancement (LGE) T2-weighted magnetic resonance imaging obtained represented using a...
Different analytical tools were used to determine the seroprevalence of and risk factors associated with Leptospira spp infection in 192 domestic dogs (Canis familiaris) Bogotá, Colombia. Using microscopic agglutination test (MAT), a battery 16 serovars tested. The was calculated as 36.46% (95% CI 0.30-0.43). A questionnaire applied dogs' owners at time sampling variables "Water sources near home" "Dog hunting rodents" identified for leptospirosis occurrence urban area Bogotá. Geographical...
