Molecular identification of different Theileria and Babesia species infecting sheep in Sudan

The epidemiological aspects of sheep piroplasmosis in Sudan are poorly studied, and further investigations using sensitive and precise techniques are required. In this study, the Reverse Line Blot (RLB) hybridization assay was used to detect and simultaneously differentiate between Theileria and Babesia species. DNA was extracted from blood collected on filter paper (n=219) from apparently healthy sheep from six different geographical localities in Sudan. Results indicated that Theileria ovis (88.6%), T. separata (20.1%), T. lestoquardi (16.4%) and T. annulata (16.4%) DNA could be detected in the blood samples. Single and mixed Theileria infections were detected in 74 (33.8%) and 124 (56.6%) respectively and T. ovis being the most prevalent species in the country. T. ovis and T. separata were reported for the first time in sheep in Sudan.University of Elimam Elmahadi, Ministry of High Education and Scientific Research, Sudanhttp://www.bioone.org/loi/copaam2016Veterinary Tropical Disease

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Coinfections of Sudanese dairy cattle with bovine herpes virus 1, bovine viral diarrhea virus, bluetongue virus and bovine herpes virus 4 and their relation to reproductive disorders

Objective: The aim of this study was to investigate the seroprevalence of coinfections with bovine herpes virus-1 (BHV-1), bovine viral diarrhea (BVD), bluetoungue virus (BTV) and bovine herpes virus-4 (BHV-4) in cattle with reproductive problems in Sudan, and to determine the relation of single or mixed seropositivity with abortion, infertility and death after birth. Materials and methods: Meta-analysis of the results from our earlier serosurveys conducted with a total of 688 dairy cattle was carried out in order to determine prevalence of seropositivity of single and mixed (coinfection) viral infections. Reults: The meta-analysis of the data indicated high seroprevalence of coinfections with various combinations of these agents; only few animals were singly infected. An infection with BHV-1 was observed to be higher than the prevalence of associations between BHV-1 and the other three viral agents. Prevalence of seropositivities to coinfection with BHV-1/BTV; BHV-1/BVD; BHV-1/BTV/BVD were the highest while seropositivities prevalences that involved BHV-4 were much lower. The highest abortion rates were encountered in coinfections with BHV-1/BVD/BTV (31%) and BHV-1/BVD/BTV/BHV-4 (30%) while most infertility cases were noticed in coinfection with BHV-1/BVD/BTV (44%) and BHV-1/BVD/BTV/BHV-4 (21%), and coinfections with the four viruses were encountered in most of the death after birth cases (25%). Overall mixed infections with BHV-1/BVD/BTV (34%) and BHV-1/BVD/BTV/BHV-4 (22.5%) were involved in the majority of reproductive problems studied. Conclusion: Mixed infections constitutes the vast majority of cases and are involved in the majority of reproductive disorders investigated. The high prevalence of seropositivity to all of the four viruses should call for an intervention strategy to reduce the impact of these viruses. [J Adv Vet Anim Res 2016; 3(4.000): 332-337

Seroprevalence of Neospora caninum in cattle in Sudan

Aim: This cross-sectional survey was conducted to detect anti- N. caninum antibodies in bovine dams ' sera samples in nine States of the Sudan. Materials and Methods: Two hundred and seventy six bovine dams ' sera samples collected from nine States in the Sudan were screened for anti-Neospora caninum antibodies using a commercial competitive ELISA (cELISA) kits. Results: The results showed an overall prevalence rate of 15.9 % (range 6.7 %- 70%) of Neospora caninum antibodies. The prevalence rates were high in White Nile (70%) and North Kordofan (30%), moderate in the Northern (15.6%), Red Sea (13.3%) States and was low in the South Kordofan (9.4%) and River Nile (6.7%). States with high values of percentage inhibition (PI) detected in White Nile State compared to other States. No antibodies were detected in El Gadarif, Kassala and South Darfur States. The prevalence was observed to be high in crossbred dams (70%) with statistically significant difference (P<0.05) compared to local ecotype (9.3%). However, no correlation was observed between infection rates in two age groups. Conclusion: Neosporosis is prevalent in cattle in most States of Sudan. Absence of evidence of infection in three of the States investigated may reflect the small number of herds and sera tested

The Association of High Prevalence of Trophozoites in Peripheral Blood with Lower Antibody Response to P. falciparum Infected Erythrocytes among Asymptomatic Children in Sudan

Background. The most prominent variant surface antigens (VSAs) of Plasmodium falciparum are the var gene-encoded Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) family, which serves as a parasite-sequestering ligand to endothelial cells. In this study we have examined the antibody reactivity of autologous plasma from symptomatic and asymptomatic malaria infected children against the infected erythrocytes’ surface antigens using flow cytometry. Methods. Ethidium-bromide-labelled erythrocytic mature forms of P. falciparum parasites obtained from symptomatic and asymptomatic children were sequentially incubated with autologous plasma and fluorescein isothiocyanate-conjugated (FITC) antihuman IgG. Plasma antibody reactivity was detected by flow cytometry. Results. Asymptomatic children had more prevalence of trophozoites in peripheral blood (66%) compared to symptomatic children (16%), p=0.002. The mean percentage of infected RBCs reacting with autologous sera was 89.78 among symptomatic children compared to 79.62 among asymptomatic children (p=0.09). Moreover, the mean fluorescence intensity (MFI) in the asymptomatic was significantly higher compared to symptomatic children (p value = 0.040). Conclusion. Variant surface antigens on Plasmodium falciparum infected RBCs from symptomatic malaria children tend to be better recognized by IgG antibodies. This may suggest a role of some IgG antibodies in severity of malaria
