Abstract Background Hydatid disease or cystic echinococcosis (CE) is caused by the larval stages of the cestode parasite Echinococcus granulosus. The objectives of this study were to estimate the prevalence of seropositivity and to identify the risk factors associated with the disease among humans in Khartoum State, Central Sudan. Methods A cross-sectional study was conducted between November 2017 and April 2018. A total of 305 randomly selected consenting participants from three localities were included in the current investigation using a multistage probability sampling method. An in-house enzyme-linked immunosorbent assay was used to detect immunoglobulin G antibodies to E. granulosus. The χ2 test and logistic regression analysis were used to determine the risk factors associated with CE seropositivity. Results A seroprevalence of 6.5% (20/305) was recorded among humans in Khartoum State, Central Sudan. Age (odds ratio [OR] 16.61 [confidence interval {CI} 2.21 to 117.92], p=0.006), locality (OR 3.08 [CI 1.42 to 22.54], p=0.011) and contact with dogs (OR 2.34 [CI 0.026 to 0.646], p=0.013) were recorded as potential risk factors for seropositivity to CE in the study area. Conclusions The seroprevalence of CE (6.5%) is high among humans in Khartoum State, Central Sudan. Improved surveillance is necessary to optimize control and prevention strategies for CE as an important neglected zoonotic disease among the human population in the study area of Central Sudan.

A cross-sectional study was conducted in Wukari, Taraba state, Nigeria, to determine the prevalence of Brucella antibodies and the risk factors associated with brucellosis in indigenous breeds of goats. A total of 386 goats were sampled from three political wards: Puje, Avyi, and Hospital: harvested sera samples were subjected to Rose Bengal Plate Test (RBPT). GraphPad Prism version 7.03 for Windows (GraphPad Software, La Jolla California, USA) was used to analyse the association between seroprevalence of brucellosis and age, sex, breed, location, and management system by using Chi square and Fisher’s exact test as appropriate. Brucellosis was detected in all three wards: Puje; 15%, Avyi; 6.6%, and Hospital; 7.6%. A prevalence rate of 2.8%, 8%, 18.7%, and 1% was recorded for <20-month, 22-35-month, 36-45-month, and ≥46-55-month age categories, respectively (P < 0.05). Only 9.5% was observed for male animals while 9.8% was observed for female animals with no statistical difference between the males and females. Breed-specific seroprevalence yielded 7.4%, 5.4% 12%, 12.8%, and 11.6%, for Cross, West Africa Dwarf, Red Sokoto, Kano Brown, and Sahel breeds of goat, respectively. There is an evidence of brucellosis (9.6%) in Wukari L.G.A, Taraba State, and age is a risk factor for the disease in the study area. There is a need to enlighten the public on the zoonotic potentials and economic impacts of brucellosis.

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.

Contagious caprine pleuropneumonia (CCPP) has been identified as a significant problem in goat production, especially in the arid and semiarid lowland areas of Ethiopia. Even though CCPP was reported in most of the goat rearing areas of the country, there is no adequate information on the disease in the Amhara Region. Cross-sectional study was conducted from November 2016 to April 2017 in the districts of Western Amhara to estimate the seroprevalence and identify the associated risk factors for occurrence of the CCPP. The risk factors considered included age, sex, agroclimate, and districts. A competitive enzyme-linked immunosorbent assay (cELISA) was carried out on a total of 400 goat sera samples, out of which 34 samples were found seropositive for specific antibodies against CCPP, with the overall seroprevalence of 8.5% (95% confidence interval (CI) =5.8, 11.2). Among the epidemiological factors considered, age and sex of the goats were not significantly associated with CCPP seroprevalence (p>0.05). However, the seropositivity was slightly higher in adults (9.9%) and female goats (9.0%) compared to young (6.3%) and male (7.5%) goats, respectively. The analysis of seroprevalence by district shows that the seroprevalence of CCPP in Metema (OR=14.34; 95%CI= 1.80, 114.09; p=0.012) and Fogera (OR=9.99; 95%CI= 1.10, 91.16; p= 0.041) was significantly higher compared to other study districts. Multivariable logistic regression analysis also identified the district as a risk factor for the occurrence of a high seroprevalence of CCPP. The present study revealed the seroprevalence and the distribution of CCPP in Western Amhara districts, and hence appropriate control measures including regular investigation and vaccination should be implemented to alleviate the problem.

Background. This research was aimed at evaluating the seroprevalence of acute and chronic Toxoplasma gondii (T. gondii) infection in pregnant women and related risk factors in southwest Iran. Methods. In this cross-sectional study, eighty-eight pregnant women were included from October 2019 to December 2019. The presence of anti-T. gondii IgM and IgG antibodies was measured using the enzyme-linked immunosorbent assay (ELISA). In addition, a questionnaire consisting of demographic information was completed for each subject. Results. The overall seroprevalence of T. gondii infection was estimated to be 34.09% (30/88). Of these, 1 (1.13%) and 29 (32.95%) samples were found positive for IgM and IgG, respectively. Regarding the risk factors, the consumption of raw/undercooked meat ( P value = 0.007) and history of abortion ( P value = 0.017) were significantly associated with IgG seroprevalence in pregnant women. Conclusion. The results showed that the pregnant women of southwest Iran might be moderately exposed to T. gondii. Since the risk of acute T. gondii infection in this susceptible group is very important, regular screening tests to diagnose the infection are recommended before pregnancy.

A cross sectional study was conducted to measure the prevalence; and identification of risk factors associated with clinical mastitis in dairy cows at Patiya upazila under Chittagong district of Bangladesh from 20th July to 31st December, 2013. A total of 160 farms and households were selected and 634 cows were clinically examined for determining the prevalence of mastitis and identification of risk factors. The overall prevalence of clinical mastitis was found 8.36%. Mastitis prevalence in crossbred cows was significantly (P<0.05) higher (10.09%) than indigenous cows (4.26%). The prevalence of mastitis was also significantly higher (P<0.05) with advancing age (12.5%) and in 3rd lactation period (13.62%). The cows were more prone to mastitis during 1st month of lactation (17.53%). There was a significant relationship (P<0.05) between prevalence of clinical mastitis and associated risk factors like general physical condition, herd size, frequency of dung removal, floor drainage quality and condition of floor. There was higher (P<0.01) prevalence (33.67%) of mastitis in cows having history of peri-parturient disease compared to those not having such history. Therefore, it can be concluded that minimization of risk factors of mastitis is very much necessary to control mastitis as well as to increase profitability of dairy farms.International Journal of Natural Sciences (2014), 4(1) 5-9

Toxoplasmosis is a parasitic disease caused byToxoplasma gondii(T. gondii). The parasite has cosmopolitan distribution, infecting almost all species of warm-blooded animals. LatentT. gondiiinfection in HIV/AIDS patients is a risk for development of cerebral toxoplasmosis (CT). The aim of this study is to determine seroprevalence of latentT. gondiiinfection and assess its associated factors among individuals infected with HIV in Arba Minch Hospital, south Ethiopia. A facility-based cross-sectional study involving 170 HIV-infected individuals attending Arba Minch Hospital antiretroviral therapy (ART) clinic was conducted from April to June 2013. Data on demographic profile of the study participants and factors associated withT. gondiiinfection were gathered using a questionnaire. Serum was tested for IgG anti-T. gondiiantibody by enzyme-linked immunosorbent assay (ELISA). Data were analyzed using SPSS version 20 software. Seroprevalence of latentT. gondiiinfection among the study participants was 88.2%. Consumption of raw meat (AOR = 4.361; 95% CI: 1.409–13.496) and involvement in farming/gardening activities (AOR = 4.051; 95% CI: 1.112–14.758) were independent predictors ofT. gondiiseropositivity. This study revealed high prevalence of latentT. gondiiinfection, similar to other studies. Monitoring of the patients to prevent reactivation of the latentT. gondiiinfection is recommended.

Brucellosis is a worldwide zoonotic disease which is now considered endemic in most parts of Egypt. A cross-sectional study was carried out from December 2018 to February 2020 to investigate the seroprevalence of brucellosis in humans and livestock residing in two regions located in New Valley Governorate, Egypt. A total of 1254 animals (673 cattle, 348 sheep, and 233 goats) and 523 human serum samples were examined for brucellosis using Rose Bengal test (RBT) and then randomly selected sera (15 from cattle, 7 from sheep, 3 from goats, and 45 from humans) were further analyzed by complement fixation test, enzyme-linked immunosorbent assay to compare and detect the sensitivity and specificity of RBT. The prevalence of brucellosis was 0% in cattle, sheep, and goats while it was 23.9% in humans using RBT. Concerning humans, there was a higher percentage of infection in EL Kharga (33.6%). The prevalence of this infection was also at a higher level among individuals aged above 40 years (28.57%). Furthermore, men (26.11%) were more inclined to be inflicted, compared to women (22.5%) with no significant difference. Considering the human occupation, abattoir workers were the most predominant group of people at risk (33.3%), followed by farmers (31.25%) and animal keepers (20.6%) while the lowest prevalence was demonstrated in the housewives where the prevalence was 18.8 %. As a result, risk factors of the age range, locality, time of infection, contact with animals, and occupational groups could significantly affect the prevalence of human brucellosis in the New Valley Governorate. In conclusion, brucellosis is an alarming problem among residents of the New Valley Governorate. Thus, reducing the prevalence in humans and animals in the region of study may include restriction of the marketing the raw milk and enhancing public health awareness.

Objective: A cross sectional study was conducted between June 2017 and August 2018 in around Dakahlia governorate to identify Methicillin resistant Staphylococcus aureus (MRSA) and to determine risk factors associated with the occurrence of mastitis in dairy cows. Design: Cross sectional study Animals and samples: 130 dairy cattle (744 samples) and 181 environmental samples (36 bedding, 37 bulk tank milk BTM, 27 feed troughs, 27 water troughs, 27 milk linear and 27 worker’s nasal swabs), with a total of 925 samples were studied. Procedures: Three hundred and seventy-two quarters were examined to detect clinical and subclinical mastitis by physical examinations and California mastitis test. In addition, bacteriological isolation and identification of Staphylococcus aureus and MRSA were carried on the above milk samples of above mentioned quarters, teat swabs and environmental samples. Results: The overall prevalence of Staphylococcus aureus and MRSA was 59.4 and 22.4, respectively. The MRSA were more prevalent in mastitic quarter (X2 = 31.146, P-value = 0.000), Holstein Friesian breed (P-value = 0.021), Old aged dairy cattle (>8 years) (P-value = 0.000), Multiparous cows (P-value = 0.000), large herd size (>=2000) (P-value = 0.000). Conclusion and clinical relevance: The present result indicates that MRSA is a major cause of mastitis in dairy farms at northern Egypt, where one of the key elements for controlling its spreading depends mainly on determining its potential risk factors responsible for its existence.

Objective Needlestick injuries caused by insulin pen injection are a serious occupational hazard for health care workers in China. We evaluated the prevalence of stick injuries with insulin pen injection and identified associated risk factors. Methods This cross-sectional survey was conducted from 1 October to 30 November 2018 in two tier three hospitals in Chongqing, China. Self-administered questionnaires were developed by the Chinese Nursing Association Diabetes Care Special Committee. We analyzed associations between potential risk factors and injuries at different operational steps. Results A total 233 of 302 (77%) participants (mean age 28.5±5.3 years) reported a needlestick incident. Most respondents (49%) had 3 to 10 years’ working experience and had received injection safety training. Most needlestick injuries occurred while recapping needles after injection. The risk of injury was significantly associated with department and job position. The injury rate increased with increased number of years worked. Respondents with ≥10 years working experience reported the highest needle-capping injury rate (88%): odds ratio 1.93, 95% confidence interval, 1.01 to 3.69. Conclusion Recapping needles after injection showed the highest risk for stick injury with an insulin pen. Nurses in the surgery department and those with longer work histories were more likely to be injured.

A cross-sectional study was carried out from July 2011 to September 2013 to assess the seroprevalence and identify risk factors of Toxoplasma gondii infection in domestic ruminants of East Hararghe zone of Oromia region, Ethiopia. Sera of 1360 domestic ruminants were analyzed for the presence of anti-T. gondii IgG antibodies using the indirect enzyme-linked immunosorbent assay (iELISA). Additionally, the owners were also interviewed using a structured questionnaire to identify the potential risk factors of T. gondii infection. Overall, the prevalence of T. gondii infection in domestic ruminants was 22.2% (302/1360). The seroprevalence in sheep, goats, cattle, and camels was 33.7%, 27.6%, 10.7%, and 14.4%, respectively. District, species, sex, age, and water source were identified as risk factors for T. gondii infection. Increased seropositivity was observed in females (OR = 2.63) and also with the use of pond (OR = 4.25) and pipe (OR = 9.57) water sources in sheep; age >1 year old (OR = 3.45) and with drinking from pond (OR = 6.03) and pipe (OR = 11.61) water sources in goats; with the use of pond (OR = 5.60) and pipe (OR = 10.68) water sources in cattle; and in >4-year-old camels (OR = 2.49). In conclusion, T. gondii infection is common and widespread among the domestic ruminants of the study area, indicating the potential transmission to humans from these animals when they are used as a source of food. Hence, it is crucial to raise awareness of the people about T. gondii infection and conduct further study to explore the impact of the disease on food animal production.
