Brucellosis is an important zoonotic disease causing reproductive problems and abortions in bovines leading to huge economic losses to the dairy industry. Seroepidemiology and risk factors associated with brucellosis were investigated in cattle and buffaloes of Chhattisgarh, India. A total of 374 serum samples from bovines were collected randomly from 94 villages of six districts of Chhattisgarh state with different attributes and were screened by i-ELISA for the detection of antibodies. The overall true seroprevalence for brucellosis was observed to be 14.17%. Brucellosis was significantly more prevalent in animals of organized farms, cross bred, age above 7 years, clinically ailing ones particularly cases of abortion and repeat breeding compared to apparently health animals. The finding represented a major impact on animal health and productivity as well as a high risk to the human population.

Abstract Background Bluetongue (BT) is a vector-borne viral disease of ruminant and camelid species which is transmitted by Culicoides spp. The causative agent of BT is bluetongue virus (BTV) that belongs to genus Orbivirus of the family Reoviridae. The clinical disease is seen mainly in sheep but mostly sub-clinical infections of BT are seen in cattle, goats and camelids. The clinical reaction of camels to infection is usually not apparent. The disease is notifiable to the World Organization for Animal Health (OIE), causing great economic losses due to decreased trade and high mortality and morbidity rates associated with bluetongue outbreaks. The objective of this study was to investigate the seroprevalence of BTV in camels in Kassala State, Eastern Sudan and to identify the potential risk factors associated with the infection. A cross sectional study using a structured questionnaire survey was conducted during 2015–2016. A total of 210 serum samples were collected randomly from camels from 8 localities of Kassala State. The serum samples were screened for the presence of BTV specific immunoglobulin (IgG) antibodies using a competitive enzyme-linked immunosorbent assay (cELISA). Results Seropositivity to BTV IgG was detected in 165 of 210 camels’ sera accounting for a prevalence of 78.6%. Potential risk factors to BTV infection were associated with sex (OR = 0.061, p-value = 0.001) and seasonal river as water source for drinking (OR = 32.257, p-value = 0.0108). Conclusions Sex and seasonal river as water source for drinking were considered as potential risk factors for seropositivity to BTV in camels. The high prevalence of BTV in camels in Kassala State, Eastern Sudan, necessitates further epidemiological studies of BTV infection in camels and other ruminant species to better be able to control BT disease in this region.

Aim: The objectives of this study were to determine the prevalence and associated risk factors of bluetongue virus (BTV) in sheep and bovine ephemeral fever virus (BEFV) in dairy cattle in Jordan. Materials and Methods: A simple randomized study was designed to collect 600 serum samples from sheep and 300 serum samples from dairy cattle located in the Northwestern parts of Jordan. In addition, data regarding farm management were collected using a pre-tested questionnaire through personal interview to determine potential risk factors. The seroprevalences of BEF and BTVs were determined using serum neutralization test and BTV group-specific competitive enzyme-linked immunosorbent assay, respectively. Results: The overall seroprevalence of neutralizing antibodies against BEFV in dairy cattle was 45.37%. The overall seroprevalence of BTV group-specific antibodies in sheep was 47.8% (54% true seroprevalence). Logistic regression analysis identified geographic location (Irbid) (odds ratio [OR]=1.0; confidence interval [CI]=0.5-2.1), no use of disinfectants on the farm (OR=1.0; CI=0.05-0.1), and lack of veterinary services (OR=10; CI=3.5-13.2) as risk factors associated with high seropositivity against BTV in sheep. Geographic location (Jarash) (OR=3; CI=1.0-5.5), age of the animal (1-2 years of age (OR=1; CI=0.3-1.9), and lack of veterinary services (OR=9; CI=4-11) were identified as risk factors associated with high seroprevalence against BEFV in dairy cattle. Conclusion: Results of this study indicate that BEFV in dairy cattle and BTV in sheep are endemic in Northwestern regions of Jordan. Implementation of appropriate control measures is, therefore, required to reduce the adverse effects of these diseases on animal health and productivity.

ABSTRACT: Leptospirosis is a zoonosis that is widely distributed in tropical countries. This infection is also associated with reproductive losses in livestock, which has a significant economic impact. The objective of this study is to investigate the seroprevalence and risk factors associated with leptospiral infection in commercial sheep flocks from the northwestern mesoregion of Rio Grande do Sul. Serum samples were analyzed in 319 sheep using the Microscopic Agglutination Test (MAT). At the time of sampling, an individual and herd questionnaire was carried out to investigate the risk factors. On an individual level, positive reactions were observed in 5.6% (18/319) of the studied sera, with Sejroe being the most prevalent serogroup. Animals >3 years old were more likely to be seropositive than animals 1-3 years old (OR 14.4; 95% CI 1.9-110). The predominance of Sejroe serogroup in this manner draws attention to how subclinical infection is associated with economic losses. Therefore, the importance of maintaining measures for the prevention and control of leptospirosis among the sheep flocks of the studied region is reiterated.

Background: Drug-related problems (DRPs) are a frequent reason for emergency departments (EDs) visits. However, data about the risk factors associated with EDs revisits are limited. Objective: To develop and validate a predictive model indicating the risk factors associated with EDs revisit within 30 days of the first visit. Methods: A retrospective cohort study was conducted involving patients who attended an ED for DRPs related to cardiovascular drugs. A 30-day prediction model was created in a derivation cohort by logistic regression. An integer score proportional to the regression coefficient was assigned to the variables with P < .100 in the multivariate analysis. Results: 581 patients (mean age: 80.0 [12.6] years) were included, 133 (22.9%) revisited the ED within 30 days from discharge. Six factors (chronic kidney disease, chronic heart failure, visit to an ED in the preceding 3 months, high anticholinergic burden, DRPs associated with heparin, and safety-related DRPs) were identified as risk factors and combined into a final score, termed the DREAMER score. The model reached an area under the receiver operating curve values of 0.72 (95% confidence interval [CI] = 0.67-0.77) in the referral cohort and 0.71 (95% CI = 0.65-0.74) in the validation cohort ( P = .273). Three risk categories were generated, with the following scores and estimated risks: low risk (0-8 points): 11.6%; intermediate risk (9-14 points): 21.3%; and high risk (>14 points): 41.2%. Conclusion and Relevance: The DREAMER score identifies patients at high risk for ED revisit within 30 days from the first visit for a DRPs, being a useful tool to prioritize interventions on discharge.

OBJECTIVE: To estimate the prevalence of high-risk human papillomavirus (HR-HPV) anal infection and associated factors in human immunodeficiency virus (HIV) positive patients in Medellín. METHODS: Descriptive cross-sectional study in 300 HIV-positive patients, adults, with history of anal intercourse, treated in two health care services of Medellín 2017–2018. We conducted a structured survey on sociodemographics, sexual behavior and medical history. HPV was detected in anal swabs tested by the COBAS 4800 system. Exploratory data analysis of risk factors associated with HR-HPV was conducted by chi-square test of independence and both raw and adjusted prevalence ratios used the Poisson regression model, at a 95% confidence interval. RESULTS: The high-risk HPV had a prevalence of 82.7%; HPV16 had a prevalence of 32.7%, HPV18 a prevalence of 21.7% and other HPV types scored 78.3%. The high-risk HPV prevalence in women was of 68.2% and 83.8% in men. The risk factors associated with high-risk HPV after adjustment were age under 30 years, elementary education, casual sex partners, and first sexual activity before 18 years old. CONCLUSIONS: The high incidence of high-risk HPV, along with the occurrence of coinfections by multiple types in the study population shows their susceptibility to develop some type of anal intra-epithelial neoplasia. It is important to establish sexual health programs focused on primary health care.

A cross sectional study on infectious bursal disease was conducted in apparently healthy backyard chicken at Waliso district of Southwestern Shoa, central oromia, Ethiopia from from November, 2018 to October, 2019. A total of 282 chickens were randomly selected to estimate seroprevalence of IBD infection and to identify the likely potential risk factors for the disease. Serum samples collected and serological test conducted in laboratory at National Animal Health Diagnosis and Investigation Center Sebeta, Ethopia. Out of 282 serum samples tested 224 were positive for indirect ELISA technique and the overall seroprevalence of IBDV in the study area was found to be 79.43% at individual level. Educational level of owners, kebeles and flock size significantly affect seroprevalence of IBD in the study area. The effect of difference in managements like source of replacement, frequency of house cleaning, use of disinfectant and isolation practice has a significant effect on IBDV sero-prevalence. A lower seroprevalence of IBDV was reported in good hygienic level of house (26.7%) than poor level of chicken house hygiene (96.4%) with statistically significant difference (P < 0.05). The seroprevalence of IBDV in the present study associated with chicken management, flock size, owner education level and other animal related risk factors for occurrence of the disease. Therefore, awareness on chicken health management, and importance of immunization would help to minimize the prevalence of the disease and play crucial role in the control of the disease. Furthermore, characterizing virus strains circulating in the area in future study is recommended.

Contagious bovine pleuropneumonia (CBPP) is an important infectious disease of respiratory system of cattle, caused by Mycoplasma mycoides subspecies mycoides. A cross sectional study was conducted in Lahore, Kasur and Jhang districts of Punjab to determine the prevalence of CBPP. A total of 560 serum samples were examined for the specific antibodies against M. mycoides subspecies mycoides, using a sandwich enzyme-linked immunosorbent assay. Associated risk factors that were evaluated include age, gender and breed. In this study, the overall seroprevalence was 8.75%. The seroprevalence of CBPP in Lahore, Kasur and Jhang were 8.26, 8.20 and 10.06%, respectively, but no significance difference (P less than 0.05) was observed. Among the assessed potential predisposing factors, gender and breed were not significantly associated with the serological status of the animal (P greater than 0.05), in which the age affected significantly the positivity to CBPP (P less than 0.05). The highest seropositivity was observed in animals of more than 7 years of age (32.08%) followed by in 4-7 years of age (8.16%) and lowest in animals of less than 4 years old (0.79%). This study confirms the presence of CBPP in the state which could be a threat to livestock export market and warrants the implementation of control measures to mitigate the economic losses associated with the disease.

The transit of infected animals may be a route for the introduction and dispersal of diseases, which necessitates protocols for the controlled entry of infected animals into herds. The objective of this study was to determine the prevalence of anti-Leptospira and anti-Brucella ovis antibodies in small ruminants sold at an animal fair in the Sertão region of the Pernambuco State, Northeastern Brazil, and to identify the possible risk factors associated with seropositivity. Serum samples were collected from 233 goats and 119 sheep, belonging to twelve different owners from November 2014 to June 2015. Diagnosis of Leptospira spp. infection was established using the microscopic agglutination test (MAT); for B. ovis infection, the agar gel immuno-diffusion (AGID) test was conducted. A total of 16/233 (6.87%; 95% CI = 4.27% – 10.83%) goats and 16/119 (13.45%; 95% CI = 8.67% – 21.24%) sheep were identified as seropositive for Leptospira spp. The most frequent serotype was Icterohaemorrhagiae. In goats, intensive management system (odds ratio = 15.8; p < 0.001) and consorted rearing of equines and goats (odds ratio = 7.3; p = 0.005) were identified as risk factors. There were no risk factors identified for sheep. Seven (5.88%; 95% CI = 2.88% – 11.65%) sheep were seropositive for B. ovis, and the intensive management system was identified as the risk factor (odds ratio = 11.5; p = 0.005). This suggests that Leptospira spp. and B. ovis infections occur in small ruminants commercialized in the Sertão region of the Pernambuco State. Thus, improvements to the sanitary conditions of the facilities and the control of synanthropic rodents are recommended.
