Pelger-Huet (P-H) anomaly is a benign congenital anomaly of leukocytes, characterized by nuclear hyposegmentation of granulocytes. Patients with heterozygous form of P-H anomaly are not immunodeficient and not predisposed to infection. In this study, P-H anomaly has been detected during a routine blood examination conducted on a clinically normal five years old male Basenji dog. Nuclear hyposegmentation of neutrophils with mature coarse chromatin pattern was noticed. As the animal was in a good health and all other blood parameters were within normal reference range, P-H anomaly was suspected. Acquired, pseudo P-H anomaly was excluded by detecting the same unique nuclear pattern in three successive blood samples collected at month intervals. Nuclear morphology was variable as dumbbell shaped, peanut shaped, band, round or bilobed forms were mostly detected in the neutrophils. It is the first report for this anomaly in Libya.

This study was conducted to investigate the presence of Enterococcus spp. in meat, meat products and seafood. A hundred and four samples were randomly collected from different geographic localities in Libya. The samples were subjected to microbiological analysis for enumeration and isolation of Enterococcus spp. by conventional cultural and molecular identification using PCR and partial sequencing of 16S rDNA techniques. Out of 104 samples, 73 (70.2%) isolates were found to be enterococci based on their cultural characteristics on ESD medium. However, out of 36 samples subjected to molecular identification, only six isolates were confirmed to be Enterococcus spp. using PCR and partial sequencing of 16S rDNA technique. All enterococci strains tested for their antibiotic sensitivity profiles showed high percentage of multi-resistance phenotype. These results can be used for further studies on enterococci as an emerging food borne pathogen and its role in human infection in Libya and would suggest that meat, meat products and seafood might play a role in the spreading of enterococci through the food chain with antimicrobial resistance characteristics.

Background: Cronobacter sakazakii is associated with illness in infants from contaminated powdered infant formula (PIF) and it is frequently recovered from PIF factory environment. Limited information is available on contamination of other food such as dairy and meat products in Libya. Methods and Findings: A total of 261 samples of milk, dairy products and coarse ground meat products were collected from different localities in Libya. Samples were examined for Cronobacter spp. with an adapted ISO /DTS 22964 cultural protocol using HiChrome™ Enterobacter sakazakii modified agar coupled with 16S rDNA partial sequencing to identify the organism. The identified isolates were biochemically characterized and tested for their ability to produce yellow pigment. Out of the 261 analyzed samples, only two beef burgers, one fermented milk “Laban”, one she-camel’s milk, two raw cow’s milk, two cereal baby food, one Maassora cheese and one ready to feed baby milk were contaminated with Cronobacter spp. at a total rate of 3.8%. Accuracy of HiChrome Ent. sakazakii modified agar reach 100% as all of blue-green presumptive colonies were confirmed Cronobacter spp. while other colorless, greenish or with blue center colonies which competed growth with Cronobacter spp. were predominantly Escherichia coli followed by Klebsiella spp. and to less extent Pseudomonas luteola, Citrobacter freundii and Acinetobacter baumanii. Moreover, the isolated strains of Cronobacter were resistant to Amoxicillin, Erythromycin, Vancomycin and Streptomycin, and sensitive to Doxycycline, Enrofloxacin and Gentamycin. Conclusion: This study documents for the first time the occurrence of Cronobacter spp. in beef burger, raw cow’s m​i​ …
