An outbreak of gout was investigated in a growing layers farm of 45000 birds located in Tripoli, Libya. Mortality was commenced at 39 days-old reaching to a total of 489 birds within 10 days. Post mortem was conducted and kidney tissue samples were fixed in 10% neutral formalin prior to processing. Feed samples were sent to the Animal Nutrition Department for analysis which revealed 23.47% crude protein and 3.5% calcium. Gross lesions comprised of deposition of chalky white material covering the pericardium and enlarged kidneys with necrotic foci, hemorrhage and nephrosis. Most of birds showed swollen ureter of one or both sides. Histopathologically, severe damage of tubules characterized by moderate to severe tubular dilation and necrosis and central bluish gouty deposition surrounded by radiations of needle like urate crystals followed by granulomatous reaction of lymphocytes, macrophages and fibroblasts. The collecting renal tubules, urinephric ducts and ureters were also filled by gouty deposits with epithelial hyperplastic changes and chronic inflammatory cellular reaction in their walls. The interstitial tissue showed edema, congestion, hemorrhage and lymphomononuclear cell infiltration. This gout outbreak in growing layers is attributed to high concentration of crude protein and calcium in diet.

A study was conducted to determine the effect of three native plants from El-Jabal al ELAkhdar, (Libya) on performance and cecal coliform count of broiler chickens. A total of 1260 one-day-old male Cobb chickens were used in the experiment. The birds were assigned to 7 treatment groups (6 replicates per treatment). The dietary treatments included basal diet with no additive (control), and 6 other dietary treatments (Arbutus pavarii, Salvia officinalis and Zizyphus Vulgaris) each of which was added at the rate of 0.5 g and 1 g/kg of basal diet. Results explicitly revealed that all dietary treatments had a significant effect on body performance of broiler chickens compared to the control with the exception of the dietary treatment of S. officinalis at dosage of 0.5 g/kg that has expressed noticeable reduction in body weight. Coliform counts in the cecum of birds receiving 1% A. pavarii and 1% Z. Vulgaris were significantly lower (P ⩽ 0.05) than those of control group from early weeks of treatments, whereas all plant shows a significant lowering (P ⩽ 0.05) of cecal coliform count during the rest of experiment compared to control group. These results emphasize the potential biotic role of such plants together with the immune modulating effects on treated birds. However, further pharmacological and clinical work should be adopted in the future to present an obvious understandable theory behind the potential beneficial as well as side effects of such natural plants.

There were only 75 confirmed cases of coronavirus disease 2019 (COVID-19) reported in Libya by the National Center for Disease Control during the first two months following the first confirmed case on 24 March 2020. However, there was dramatic increase in positive cases from June to now; as of 19 November 2020, approximately 357940 samples have been tested by reverse transcription polymerase chain reaction, and the results have revealed a total number of 76808 confirmed cases, 47587 recovered cases and 1068 deaths. The case fatality ratio was estimated to be 1.40%, and the mortality rate was estimated to be 15.90 in 100000 people. The epidemiological situation markedly changed from mid-July to the beginning of August, and the country proceeded to the cluster phase. COVID-19 has spread in almost all Libyan cities, and this reflects the high transmission rate of the virus at the regional level with the highest positivity rates, at an average of 14.54%. Apparently, there is an underestimation of the actual number of COVID-19 cases due to the low testing capacity. Consequently, the Libyan health authority needs to initiate a large-scale case-screening process and enforce testing capacities and contact testing within the time frame, which is not an easy task. Advisably, the Libyan health authority should improve the public health capacities and conduct strict hygienic measures among the societies and vaccinate as many people against COVID-19 to minimize both the case fatality ratio and socio-economic impacts of the pandemic in Libya.
