Background: This study was conducted to investigate the presence of Bacillus cereus in meat, meat products and some seafood in Libya. Materials and Methods: A hundred and thirty one samples were collected from different geographic localities in Libya. The samples were subjected to microbiological analysis for enumeration and isolation of B. cereus by conventional cultural, biochemical and molecular identification by using PCR and partial sequencing of 16S rDNA techniques. Results: Out of 131 samples, only 38 (29%) isolates were found to be B. cereus based on their cultural characteristics on MYP medium, that included 30% beef, 38.2% beef products (minced, burger, kabab and sausage), 31.8% camel meat and 48% chicken products (burger, sausage, kabab and liver). However, B. cereus was not detected from mutton and seafood samples. Seventeen isolates were subjected to molecular identification by using PCR and partial sequencing of 16S rDNA technique and confirmed to be B. cereus. The confirmed B. cereus strains tested for their antibiotic sensitivity profiles and showed high percentage of multi-resistance phenotype. Conclusions: The results provide better understanding of B. cereus isolated from food of animal origin in Libya and suggest that meat and meat products might play an important role in the spreading of B. cereus through the food chain with antimicrobial resistance characteristics.

The epidemiological patterns of Bluetongue (BT) in North Africa and Mediterranean Basin (MB) dramatically changed by emergence of subsequent episodes of novel bluetongue virus (BTV) serotypes with highly pathogenic indexes and socio-economic impacts. The objective of the study was to investigate the sero-prevalence and serotype distribution of BTV in Libya. During 2015-2016, a total of 826 serum samples were collected from domestic ruminants in Libya. All sera were assayed by competitive enzyme-linked immunosorbent assays (c-ELISA). C-Elisa-positive samples (43.3%; 173/400) were further analyzed by virus neutralization assay to identify BTV serotypes and determine the antibody titre of positive samples. An overall BTV sero-prevalence was 48.4% (95% CI: 45.0%-51.8%). Neutralizing antibodies were detected against the following BTV serotypes namely: BTV-1, BTV-2, BTV-3, BTV-4, BTV-9 and BTV-26. While BTV-1, BTV-2, BTV-4 and BTV-9 circulation was unsurprising as they have been responsible of the last year outbreaks in Northern African Countries, the detection of BTV-3 and BTV-26 was definitely new and concerning for the animal health of the countries facing the Mediterranean Basin. It is crucial that European and Northern African authorities collaborate in organizing common surveillance programmes to early detect novel strains or emerging serotypes in order to set up proper preventive measures, and, in case, develop specific vaccines and plan coordinated vaccination campaigns.

This study involved a herd consisting of 200 goats in Green Mountain area, suffering from decrease in weight gain, bloody diarrhoea and severe anaemia and in some cases death within few days. Generally, there was no response to the treatment with antibiotics, anthelmentics and multivitamins. The last animal that died was submitted for post-mortem examination. The disease affecting the herd was diagnosed as coccidiosis. This is the first report of caprine coccidiosis in the Green Mountain Area in Libya.
