Sero-Prevalence Investigation of Peste Des Petits Ruminants (PPR) and Associated Risk Factors in Libya During 2015-2016

Peste des Petits Ruminants (PPR) is considered one of the most important transboundary animal diseases (TADs) with socio-economic impacts on national and international levels. During 2015-2016 a total of 690 serum samples were collected from unvaccinated domestic ruminants of which 555 sheep, and 135 goats representing teen provinces distributed in four Libyan branches (Green Mountain, Benghazi, West Mountain and Sabha). The sample were analysed at IZSAM, Teramo, Italy, by using competitive ELISA, IDvet innovative diagnostics (IDvet, 310 rue Louis Pasteur-34790 Grabels, France). The overall sero-prevalence rate (SPR) of PPR antibodies was estimated to be 41% (95% CL: 36% to 46%) among sheep and 39% (95% CL: 28% to 45%) among goat. A chi-square test was used to evaluate the probability of differences observed among SPR of infection. The results showed that the SPR of PPR was significantly (P= 0.015) higher in adult animals 41% (95% CL= 37%-46%) than in the young 24% (95% CL= 17%- 32%). The highest SPR 75% (95% CL= 61%-85%) was recorded in Sabha province (Southern Libya) which highlighted statistically difference (P= 0.00001). The preliminary results of the present study could be useful to better focus on specific area of Libya to improve understand and evaluate the risk factors for disease spreading and to plan disease control activities as requested by FAO/OIE (PPR Global Control and Eradication Strategy). arabic 19 English 100

Seroprevalence and potential risk factors associated with Toxoplasma gondii infection in women from Tripoli, Libya

Aims: To determine the seroprevalence of Toxoplasma gondii (T. gondii) in women from Aljalla Maternity and Gynaecology Hospital (AMGH) and to evaluate the association between the infection and potential risk factors. Methods: A cross-sectional study was conducted at AMGH in Tripoli during the year 2012. Data on potential risk factors were collected by a structured questionnaire and results of the test. The output data of questionnaire were used to assess potential risk factors for positive outcome. All sera (n = 500) was screened against ToxoG, by using the Vidas machine automated enzyme-linked florescent immunoassay. The association between the outcome variables and its potential risk factors were screened in a multivariate analysis. A p-value < 0.05 was considered to be significant. Results: The overall seroprevalence was estimated to be 50.8% with 95% confidence interval (CI) (46.42%–55.18%). The results revealed that T. gondii infection is highly prevalent, and eating habits (consuming raw meat and/or raw vegetables or fruits) were highly significant associated in multivariable analysis. Expectedly, a significantly [odds ratio (OR):1.712; p =

Effect of low and high doses of Salmonella enteritidis PT4 on experimentally infected chicks

Chicks (1-d-old, three groups, each containing 50 chicks) were inoculated with 2×102 and 2×108 CFU ofSalmonella enteritidis; the third group were kept as uninoculated control. Five birds from each group were euthanized at intervals from 6 h to 4 weeks post-inoculation (pi). In the lowdose groupS. enteritidis was isolated from 60% cecal samples at 18 h pi. and from 20% of livers at 3 d pi. Individual variation in the frequency ofS. enteritidis recovery was observed in this group. The clearance of salmonella from the organs was faster in the low-dose group, and salmonella was not isolated from the liver and cecum at 21 and at 27 d, pi, respectively. However, in the high-dose group,S. enteritidis was isolated from all ceca and 80% of liver 6 h pi, and salmonella was detected in the cecum and liver throughout the experiment. Serous typhlitis and unabsorbed yolk sac were the most prevalent lesions in both groups. Granulomatous nodules in the cecum were found occasionally in some cases in both inoculated groups, which can play a role as reservoirs in carrier chicks.
