    Notes: One hundred children with suspected herpes simplex virus (HSV) infection and 20 controls were studied to compare a rapid immunofluorescence (RIF) test for detection and typing of HSV from smears of lesions with standard viral culture. The RIF test was evaluated for ease of use and speed of diagnosis.RIF and/or culture were positive in 64% of patients. All infections diagnosed by RIF and culture were HSV type 1. In 92% of patients RIF and culture results were in concordance. In 57 cases, RIF and cultures were positive for HSV infection and in 35 cases RIF and cultures were negative for HSV infection. Three patients had inadequate samples for RIF and five children had positive RIF but were culture negative. All controls had negative results both by RIF test and culture. The RIF test demonstrated 100% sensitivity and 95% specificity.The RIF test was type specific, easy to perform and gave diagnosis of HSV infections within an hour of taking the clinical specimen. This study suggests the RIF test is as good, if not more sensitive, in the diagnosis of HSV infections as standard viral culture and has the advantage of speed of diagnosis.

    Notes: Tectono-stratigraphic analysis of the East Tanka fault zone (ETFZ), Suez Rift, indicates that the evolution of normal fault segments was an important control on syn-rift depositional patterns and sequence stratigraphy. Sedimentological and stratigraphic analysis of the Nukhul Formation indicates that it was deposited in a narrow (ca 1–2 km), elongate (ca 5 km), fault-bounded, tidally influenced embayment during the low subsidence rift-initiation phase. The Nukhul Formation is composed of transgressive (TST) and highstand (HST) systems tract couplets interpreted as reflecting fault-driven subsidence and the continuous creation of accommodation in the hangingwall to the ETFZ. The overlying Lower Rudeis Formation was deposited during the high subsidence rift-climax phase, and is composed of forced regressive systems tract (FRST) shallow marine sandbodies, and TST to HST offshore mudstones. Activity on the ETFZ led to marked spatial variability in stratal stacking patterns, systems tracts and key stratal surfaces, as footwall uplift, coupled with regressive marine erosion during deposition of FRST sandbodies, led to the removal of intervening TST–HST mudstone-dominated units, and the amalgamation of FRST sandbodies and the stratal surfaces bounding these units in the footwall. This study indicates that the evolution of normal fault segments over relatively short (i.e. 〈1 km) length-scales has the potential to enhance or suppress a eustatic sea-level signal, leading to marked spatial variations in stratal stacking patterns, systems tracts and key stratal surfaces. Crucially, these variations in sequence stratigraphic evolution may occur within time-equivalent stratal units, thus caution must be exercised when attempting to correlate syn-rift depositional units based solely on stratal stacking patterns. Furthermore, local, tectonically controlled variations in relative sea level can give rise to syn-rift stacking patterns which are counterintuitive in the context of the structural setting and perceived regional subsidence rates.

    Notes: Summary To differentiate between B virus and HSV isolates from monkeys and man monoclonal antibodies (mabs) were produced to herpesvirus simiae (B virus) and herpes simplex type 1 and 2 (HSV-1 and HSV-2). Mabs were tested by indirect immunofluorescence (IFAT) for reactivity against herpesviruses from Asiatic monkeys (B virus), African monkeys (SA 8 virus), and man (HSV-1, HSV-2, varicella-zoster virus, cytomegalovirus, and Epstein-Barr virus). Mabs could be divided into groups A-E displaying specific reactivity for B virus (A); reactivity with both B virus and SA 8 but not HSV (B); reactivity with B virus, SA 8 virus and HSV strains (C); specific reactivity with HSV-1 (D); and specific reactivity with HSV-2 (E). Two of the B virus specific mabs were able to differentiate between cynomolgus and rhesus strains of B virus. None of the mabs reacted with human varicella-zoster virus, cytomegalovirus, or Epstein-Barr virus. A panel of mabs for the unequivocal identification of B virus isolates from monkey or man is proposed.
