COVID-19 and African Immigrants in North Africa: A Hidden Pandemic in a Vulnerable Setting

Since being declared a pandemic in March 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes the disease known as coronavirus disease (COVID-19), has brought difficult situations for citizens of nations worldwide. The effects, however, may be more severe for vulnerable communities, such as immigrants, who are already in desperate situations and under deteriorating conditions. There are still very limited data on how the pandemic is impacting migrant communities. Immigrant camps foster an environment that poses a great threat to the health of their inhabitants, especially at the time of a pandemic. Overcrowding, poor sanitation, inadequate health care, and difficulty containing contagious diseases are well documented in African immigration detention centers. Furthermore, they are unlikely to take priority in a moment in which governments are mobilizing all resources to care for their citizens. Their situation is even more complicated if they are hosted in corridors plagued by war, as in North Africa

Isolation and Molecular Identification of Vibrio spp. by Sequencing of 16S rDNA from Seafood, Meat and Meat Products in Libya: A Descriptive Study

The main objective of this study was to characterize bacteria isolated from seafood, meat and meat products that may cause foodborne illnesses. We plan to use this data to help create a baseline for future research into foodborne illness in Libya. Several food-borne organisms in the genus Vibrio produce a variety of clinical disorders, including septicemia, cholera, and milder types of gastroenteritis. Vibrio cholerae, Vibrio parahemolyticus, and Vibrio vulnificus are among the Vibrio spp. that are usually related with food-borne transmission. A total of 93 samples (Table 1) of seafood, meat and meat products that includes 21 of shrimps; 5 of clam; 20 of fish; 34 samples of raw meat (10 beef, 9 camel meat, 6 mutton and 9 chickens) and 13 samples of meat products (2 beef sausages, 5 beef burgers, 5 chicken burgers and 1 kebab) were randomly collected from different geographic localities in Libya [Tripoli, Regdalin (120 km west of Tripoli), Janzour (30 km west of Tripoli) and Tobruk (1400 km east of Tripoli)]. Each sample was 250 g in weight. Out of the 93 cultured samples only 48 (51.6%) yielded colonies on Thiosulfate Citrate Bile Salt agar (TCBS) with culture characteristics of Vibrio spp. More than half (n=27) of processed seafood samples (n=46) yielded colonies on TCBS, while only 44.6% of samples of meat and meat products showed colonies on TCBS. Among cultured seafood samples, the highest bacterial count was recorded in clam with a count of 3.8 х10 4 CFU\g. Chicken burger samples showed the highest bacterial count with 6.5 х10 4 CFU\g. Molecular analysis of the isolates obtained in this study, showed that 11 samples out of 48 (22.9%) were Vibrio spp. Vibrio parahemolyticus was isolated from camel meat for the

Occurrence, characterization, and antibiogram of Staphylococcus aureus in meat, meat products, and some seafood from Libyan retail markets

Aim: The aim of the current investigation was to screen the presence of Staphylococci spp., especially S. aureus in meat, meat products of different animal species, and some seafood sold in some retail markets in Libya using cultural and molecular techniques, and to study their antibiotics resistance profiles. Materials and Methods: A total of 139 samples from red meat, meat products, and seafood were collected from many areas in Libya. Enumeration and isolation of Staphylococci spp. and S. aureus by normal cultural methods followed by molecular identification using molecular techniques by bacterial DNA extraction and partial sequencing of 16S rDNA. Results: Out of 139 samples, 112 (80.6%) were contaminated with different species of Staphylococci based on cultural characteristics of Staphylococci on Baird-Parker medium, for which S. aureus was detected in only 32 samples (23%). However, only six out of 18 (33.3%) isolates sent for sequencing were confirmed to be S. aureus using the molecular technique. The six identified isolates of S. aureus were tested for antimicrobial resistance against 24 most commonly used antibiotics. All isolates were resistant to only two antibiotics (cefotaxime and clindamycin). Among these six isolates, only one confirmed to be methicillin-resistant Staphylococcus aureus. Conclusion: Results of this study suggest that food of animal origin could be a source of S. aureus with antimicrobial resistance characteristics that can be spread through the food chain, and raise the importance of these results for public health.
