Molecular characterization of Newcastle disease virus (AOAV-1) obtained from Western region of Libya.

Background: Since its discovery in 1926, Newcastle disease (ND) is still emerging in many avian species worldwide causing severe economic losses due to high mortality.

Aim: This article aims to discuss the challenge of virulent ND in poultry in Libya, focusing on recent outbreaks investigated in Alzintan, Alrayaina, Nalut, and Surman, cities located in the western region of Libya.

Methods: Clinical signs and lesions were recorded.

Effect of humic acid and probiotics on immunity of broiler chickens.

Background: The immune system in chickens has a fundamental role in controlling many diseases based on vaccination, thus enhancement of the immune system response is a priority.

Aim: The aim of this experiment was to study the effect of probiotics and humic acid on immunity of broiler chickens.

Methods: Day-old 300 Ross broiler chicks were segregated into 5 groups of 60 chicks per group.

Prevalence of in poultry slaughterhouses located in Tripoli, Libya.

Background: is a leading cause of severe economic losses in poultry and foodborne illness in humans worldwide.

Aim: The aim of this study was to determine the prevalence and multidrug resistance of Salmonella Enteritidis (S. Enteritidis) in several chicken abattoirs in Tripoli, Libya.

Results of the eighteenth winter waterbird census in Libya in 2022.

Background: Libyan wetlands are diverse; the coastline of Libya, in particular, has different kinds of wetlands, such as salt marshes, bays, lakes, lagoons, and islands. These varieties in habitats provide good shelters and foraging sites for migratory birds during their journeys between Eurasia and Africa. Since the beginning of the Libyan winter census of waterbirds International waterbirds census (Libya IWC) in 2005, which continued regularly until 2012, it has had relatively the same performance in the number of covered sites.

Pathological lesions associated with infection in Atlantic horse mackerel ( L., 1758) from the western coast of Tripoli, Libya.

Background: are aquatic bacteria causing Vibriosis in humans and aquatic animals. Vibriosis is a significant disease of cultured and wild fish.

Aim: The present study aimed to address the impact of on the health status of inhabiting the coastal area of Tripoli.

Surveillance of the spread of avian influenza virus type A in live bird markets in Tripoli, Libya, and determination of the associated risk factors.

Background And Aim: Studies on avian influenza virus (AIV) in Libya are few and limited. This study aimed to determine the presence of AIV in live bird markets (LBMs) in Tripoli and determine the risk factors associated with AIV spread .

Materials And Methods: In total, 269 cloacal swabs were randomly collected from different bird species in 9 LBMs located in Tripoli and its surrounding regions.

Seroprevalence and molecular detection of Newcastle disease virus in backyard chickens in Tripoli, Libya.

Background: Newcastle disease (ND) is a viral disease that affecting many avian species all over the world.

Aim: ND has been successfully controlled by the vaccination of commercial poultry in Libya. However, there was a lack of information about the situation of ND in backyard chickens.

Identification of phenolic compounds, antibacterial and antioxidant activities of raisin extracts.

In this study, antibacterial, antioxidant and phenolic compounds of raisin extracts was evaluated. Different solvent extraction methods were utilized to extract phenolic compounds from raisin. The phenolic compounds of raisin extracts was determined using HPLC and three compounds were found, catechin, quercetin and rutin.

Molecular detection and characterisation of avian paramyxovirus type 1 in backyard chickens and pigeons in Alzintan city of Libya.

Avian paramyxovirus-1 (APMV-1) is the causative agent of Newcastle Disease which affects many species of birds leading to high mortality and heavy economic losses among poultry industry worldwide. Newcastle disease is endemic in Libya with frequent outbreaks occurring in commercial and backyard poultry. APMV-1 was isolated and characterised during the outbreak in 2013.

Biosecurity and geospatial analysis of mycoplasma infections in poultry farms at Al-Jabal Al-Gharbi region of Libya.

Geospatial database of farm locations and biosecurity measures are essential to control disease outbreaks. A study was conducted to establish geospatial database on poultry farms in Al-Jabal Al-Gharbi region of Libya, to evaluate the biosecurity level of each farm and to determine the seroprevalence of mycoplasma and its relation to biosecurity level. A field team of 7 Veterinarians belongs to the National Center of Animal Health was assigned for data recording and collection of blood samples.

Exploiting serological data to understand the epidemiology of foot-and-mouth disease virus serotypes circulating in Libya.

Sporadic outbreaks of foot-and-mouth disease (FMD) have occurred in Libya for almost fifty years. During the spring of 2013, a countrywide serosurvey was undertaken to assess the level of FMD virus circulation and identify FMD virus serotypes in the country. A total of 4221 sera were collected, comprising samples from large ruminants (LR; n=1428 samples from 357 farms) and small ruminants (SR; n=2793 samples from 141 farms).

Characterization of Avian Influenza and Newcastle Disease Viruses from Poultry in Libya.

On March 2013, the Libyan poultry industry faced severe outbreaks due to mixed infections of APMV-1 (Newcastle disease) and low pathogenic avian influenza (AI) of the H9N2 subtype which were causing high mortality and great economic losses. APMV-1 and H9N2 were isolated and characterized. Genetic sequencing of the APMV-1/chicken/Libya/13VIR/ 7225-1/2013 isolate revealed the presence of a velogenic APMV-1 belonging to lineage 5 (GRRRQKR*F Lin.
