orrelia burgdorferi, the causal organism of Lyme borreliosis. In Egypt, available data about the occurrence of Lyme disease are scarce and no structured studies documented the presence of Lyme borreliosis in Egyptian animals and tick reservoirs verifying its zoonotic evidence. Besides, no successful trials to isolate B. burgdorferi from clinical samples have occurred. This study was conducted to investigate B. burgdorferi infection as an emerging zoonosis neglected in Egypt. A total number of 92 animals, tick and human companion specimens were collected and subjected for culture, PCR and/or serodetection. B. burgdorferi has been detected and isolated from Egyptian animal breeds. We also detected the presence of outer surface protein A gene of B. burgdorferi by PCR as well as anti-B. burgdorferi IgM by ELISA in human contacts who were suffering from fever of unknown origin. This report represents the first systematic study on animals associated with patients suffering from febrile illness to confirm the emerging of such neglected zoonosis in Egypt.

Samir, A., and M. Wasfy, "A Simple Technique for Long-Term Preservation of Leptospires", Journal of Basic Microbiology. , vol. 53, issue 3, pp. 299 – 301, 2013. Abstract

The viability of six serovars of Leptospira spp. was studied after long storage at −70°C. The bacteria were either preserved in Ellinghausen–McCullough–Johnson–Harris (EMJH) liquid growth medium or in sheep blood added as a cryoprotectant. The viability of the strains was observed on a monthly basis by dark-ground microscopy over a period of 20 months at −70°C. Addition of sheep blood was not significantly advantageous, since leptospires that were stored in EMJH showed a slight increase in number after recovery. The results suggest a very simple and useful technique for long-term preservation of such Leptospira.
