Functional insights from the GC-poor genomes of two aphid parasitoids, Aphidius ervi and Lysiphlebus fabarum.

Background: Parasitoid wasps have fascinating life cycles and play an important role in trophic networks, yet little is known about their genome content and function. Parasitoids that infect aphids are an important group with the potential for biological control. Their success depends on adapting to develop inside aphids and overcoming both host aphid defenses and their protective endosymbionts.

Physiological Maturation Lags Behind Behavioral Maturation in Newly Eclosed Males.

The accessory gland (AG) produces seminal fluid proteins that are transferred to the female upon mating in many insects. These seminal fluid proteins often promote a male's post-copulatory reproductive success. Despite its crucial function many males eclose with a small gland not yet containing the full set of proteins.

Leptospirosis in Israel: a report of 14 cases caused by icterohaemorrhagiae serogroup (1968-82).

Fourteen cases of leptospirosis due to the Leptospira interrogans serogroup Icterohaemorrhagiae (Weil's disease) were serologically confirmed in the last 15 years. In two cases, Icterohaemorrhagiae was also isolated from the patients' blood. Both positive cultures were obtained in Korthof's medium by indirect passage through brain-heart infusion medium.

Leptospirosis in Israel: epidemiological features and laboratory findings in 13 human cases due to Leptospira ballum.

Thirteen sporadic cases of human leptospirosis due to Leptospira ballum were laboratory confirmed during a period of 11 yr. In four cases the diagnosis was proved retrospectively. All but three were residents of the Sharon plain region, living 10 to 15 km apart.

Leptospirosis in man, Israel, 1970-1979.

In 1970-1979, the incidence of human leptospirosis in Israel was 0.7 per 100,000 population. The majority of the cases (62%) occurred in northeastern Israel (Upper Galilee).
