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.

In order to study microscopic and macroscopic lesions in chickens infected with low and high doses of Salmonella enteritidis PT 4 (SE), 150 one-day-old White Plymouth Rock chicks were divided into three groups each containing 50 birds. The chickens of the first and second groups were inoculated with 2 x 102 and 2 x 108 cfu of Salmonella, respectively. The chicks of the third group were kept as uninoculated control birds. Five birds from each group were euthanized by cervical dislocation at 6, 12, 18 hours post inoculation (hpi) and then after 1, 3, 7, 10, 14, 21, and 27 days post inoculation (dpi) and were examined for presence of gross and histological lesions. Catarrhal typhlitis and unabsorbed yolk sac were the most prevalent gross lesions in both groups. Histologically, granulomatous nodules in the caecum were found occasionally in some cases in both inoculated groups. The present study demonstrated that the chickens infected with a low dose of SE showed fewer lesions, which were milder in comparison with the birds inoculated with a high dose of SE. It suggests that chickens were able to capture the pathogen in the low dose group

Foot-and-mouth disease viruses are often restricted to specific geographical regions and spread to new areas may lead to significant epidemics. Phylogenetic analysis of sequences of the VP1 genome region of recent outbreak viruses from Libya and Saudi Arabia has revealed a lineage, O-Ind-2001, normally found in the Indian subcontinent. This paper describes the characterization of field viruses collected from these cases and provides information about a new real-time RT-PCR assay that can be used to detect viruses from this lineage and discriminate them from other endemic FMD viruses that are co-circulating in North Africa and western Eurasia.
