Toxoplasma Gondii Infection

Abstract Little is known about Toxoplasma gondii infection among cattle living in the Cerrado (Brazilian savanna) biome in Brazil. In particular, there is no epidemiological data relating to infection in quilombo lands, i.e. areas settled by Afro-descendants of escaped slaves. The aim of this study was to determine the prevalence, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombo, in the Cerrado biome. Blood samples were collected from 1533 cattle for antibody detection using the indirect fluorescence antibody test (IFAT). The study area was subdivided into five macroregions to determine the spatial distribution of infection. An objective questionnaire was applied to the cattle owners to evaluate risk factors, which were analyzed using univariate analysis and logistic regression. The prevalence of T. gondii infection among cattle was 8.93% (137/1533), and antibodies were found in 49.6% of the herds (66/133), in all macroregions. The risk factors associated with T. gondii infection in cattle were the following: number of animals in the herd (OR: 30.56), purchase of cattle (OR: 2.57), age group (OR: 1.95) and average annual temperature (OR: 1.77). Thus, the occurrence rate, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombola community are documented here, for the first time.

Toxoplasma Gondii Infection

Abstract This study aimed to investigate the frequency of anti-Toxoplasma gondii antibodies in serum from 629 chickens on 39 family farms in seven municipalities in the semiarid region, Pernambuco, Brazil, and to identify risk factors associated with T. gondii infection. The risk factors were studied in 421 samples from 29 farms. Anti-T. gondii antibodies were investigated by indirect fluorescent antibody test with a 1:16 cutoff. The frequency of positive chickens was 27.9% (176/629) and 94.8% of the farms studied had chickens infected by T. gondii. Multivariate analysis showed variables significantly associated with anti-T. gondii antibodies in serum: slaughter of animals on the farm, reproductive disorders in sheep, consumption of fetal adnexa and placentas by chickens, presence of sheep in the property and birth of sheep the property. The results suggest that there is a complex relationship between general management practices for different animal species raised on the same farm and the prevalence of T. gondii infection in chickens. In addition, the results draw attention to the risk of human infection by T. gondii via consumption of infected chicken meat, because the farming conditions and the low human development indices observed in the region studied result in inappropriate meat preparation practices.

Toxoplasma Gondii Infection

In this study, we aimed to determine the prevalence and risk factors associated to Toxoplasma gondii infection in sheep from northeastern Brazil. A total of 932 ovine serum samples from 54 properties in 19 municipalities of the state of Sergipe were collected and assayed using indirect fluorescent antibody test. The assay used antibodies against Toxoplasma gondii (IFAT-IgG) with a cutoff point of 1:64. We observed that 28.22% (263/932) of the ovine samples were serum-reactive. In a logistic regression, factors such as consumption of water directly from the source, consumption of water from a deep well, and age below 12 months were associated with protection; whereas factors such as presence of cats on the property, presence of slatted floor, and use of exchanged or borrowed breeding males were associated with infection. The studied area can be considered endemic for toxoplasmosis, so it is necessary to adopt preventive and control measures because this zoonotic infection poses risks to public health.

Abstract The aims of this survey were to determine the frequency of anti-Toxoplasma gondii and anti-Neospora caninum antibodies and to identify the risk factors associated with seropositivity among buffaloes in the state of Paraíba, Brazil. This survey included 136 buffaloes belonging to 14 herds. To detect anti-T. gondii and anti-N. caninum antibodies, the indirect fluorescent antibody test (IFAT) was used. Among the 136 samples analyzed, 17 (12.5%) were positive for anti-T. gondii antibodies with titers ranging from 64 to 1,024, and 26 (19.1%) for anti-N. caninum with titers from 200 to 1,600. Animals seropositive for both T. gondii and N. caninum were found in 10 of the 14 herds (71.4%). Semi-intensive management systems (odds ratio = 2.99) and presence of pigs (odds ratio = 4.33) were identified as risk factors for T. gondii and N. caninum, respectively. It can be suggested that T. gondii and N. caninum are widespread in buffaloes in Paraíba, and that additional surveys are needed in order to ascertain the importance of these agents for this species and for pigs, and the influence of the farming type on occurrences of seropositive animals.

Sera were collected from 300 domiciled cats from the municipality of Lages, Southern Brazil, to determine the prevalence of Toxoplasma gondii antibodies and risk factors associated. Tests for T. gondii antibodies were performed using indirect immunofluorescent antibody test (IFAT). Positive reactions with titers >1:64 were found in 43 (14.33%) cats. A significant number of seropositive cats were >6 month old (p = 0.03758) and had access to the streets or/and rural areas (p = 0.04185). The results indicate that T. gondii is widespread in cats in Lages with a prevalence of 14.33%.

Hand Foot Syndrome

Background: Hand-foot syndrome (HFS) is a common side effect that has a high occurrence rate with capecitabine (Cape) chemotherapy. However, little is known about the risk factors of developing HFS under the Cape regimen. Our aim was to examine these risk factors. Methods: A univariate analysis was used to determine the risk factors associated with developing HFS, and we calculated the effect sizes between the patients who developed HFS compared to those who did not. Results: Of the 52 patients enrolled in our research, 24 (46.2%) developed HFS. This group was significantly associated with hemoglobin (Hb) values (p < 0.001), and the effect size (1.21) was more than moderate. The receiver operating characteristic curve analysis confirmed 12 mg/dl Hb as the best diagnostic cut-off value for developing HFS. The sensitivity and specificity were 75.5 and 88.2%, respectively. Patients who had Hb values of 12 or below who developed HFS had longer median times without HFS compared to patients with high Hb values (115 vs. 75 days, p = 0.30, hazard ratio = 1.42, 95% CI 0.73-2.76) and a greater area under the Kaplan-Meier curves (p < 0.05). Conclusion: This research suggests that the Hb value is an important factor for developing HFS.

This study is aimed to assess the prevalence and risk factors associated with T. gondii infection in pigs. We evaluated 143 pigs, in 10 randomly-chosen farms located in Southern Piauí. The pig's blood serum was analyzed through ELISA in detection of anti-T. gondii antibodies. A seroprevalence of 25.5% was observed in the pigs that reacted against T. gondii antigens. The data from the records demonstrated an association with some factors such as: age, diet, type of management, breed and presence of cats in the farms with a prevalence of T. gondii. With the exception of sex, all others features represent risk factors for T. gondii infection. Furthermore, our data contributed to the understanding of the T. gondii seroprevalence in pig farms located in Southern Piauí.
