Pathogenicity of Different Baboon Herpesvirus Papio 2 Isolates Is Characterized by either Extreme Neurovirulence or

A second round of serology was performed to include animals with contact to the presumptive index case while in quarantine and thereafter (). These include the EBERs, BARF0, BCRF1, BARF1, and BDLF3 (Rivailler et al., 2002a). Substantial quantities of recombinant gE and sgG were retained in the infected cells, as determined by immunoblotting of infected cell pellets and supernatants with the anti-V5 MAb (data not shown), resulting in a low level of secretion and low yields of purified gE and sgG. In contrast, comparison of 13 UL39 sequences revealed a total of 38 subtype-specific AA substitutions (24 conservative and 14 non-conservative) along the 989 AA sequence alignment (3.8% subtype-specific sequence divergence; see supplemental material). To determine whether apparent functional mutations existed in TK, the TK open reading frame (ORF) was sequenced from rhesus, Japanese macaque, cynomolgus monkey, pigtail macaque, and human B virus isolates. Because of the very young age of this calf and the fact that both Asian and African elephants were housed at this facility, we cannot make any interpretations as yet about whether EEHV6 is most likely to be endogenous to either African or Asian elephants. The last recorded interval between menses was greater than 275 d, and at the time of her death, 313 d had passed without menses.

Another (albeit remote) possibility is that the HVS1 isolates used by Leib et al. If, as in mice (both in vitro and in vivo, this study) and in rabbits,2 ACV is not very effective against BV in humans, initial treatment of patients with ACV may not effectively inhibit virus replication but rather would allow the virus to replicate at the site of infection and so gain access to the nervous system. All eight sera (no. This may indicate that animals with high DNA levels effectively neutralize the virus through cellular and humoral responses but that DNA is still present in infected cells, yielding little or no viral transmission. Old World monkeys exhibit true menstrual cycles with the sloughing of the uterine wall lining at the end of the luteal phase of the cycle if fertilization has not taken place (Catchpole and Van Wagenen 1975). In addition, transiently transfected egfp-EBV TK localized to the centrosome in B95-8, an EBV-immortalized marmoset cell line, both before and after induction of lytic replication (not shown). If a large genetically diverse cohort of animals can be derived and maintained as seronegative, these animals then can become founders for an RhLCV-negative colony.

Critchley. olivacea; Aust., Australia; HI-1, Hawaii, turtle one of two; HI-2, Hawaii, turtle two of two (same source as contig); CR, Costa Rica; SD, San Diego; Barb, Barbados; FL, Florida; PR, Puerto Rico. (A) Polypeptide coverage of ORF64 identified by MS (polypeptides identified are shown in gray). Both LHV-4 ICP0 and ICP4 are smaller than those of primate simplexviruses ( and 2). Human promoter sequences were cloned into an MCS upstream of a luciferase reporter (pGL2 Basic; Stratagene, La Jolla, CA). This is the result of strong mutational GC-pressure and relatively silent negative selection. HSV can also reach the eyes causing keratitis, which may lead to blindness (13).

Editing can alter splicing regulatory elements or create/destroy splice sites [72]. The distribution of SSDs was not uniform along the HVP2 genome; there were fewer SSDs located in genes located in the left part of the UL region (genes UL4-20) than in the right part of the UL region or the US region, and overall the US region had a higher density of SSDs than the UL region. This was repeated on three separate days. It had only 78% nucleic acid and 82% amino acid sequence identity to EBV. Once plaques developed (48 hrs), individual plaques were picked and inoculated onto Vero cells. This is close to the size of between 112 and 130 kbp estimated by field inversion gel electrophoresis (FIGE) (Supplemental Fig. Macaques that need to be handled regularly should be housed in squeeze-back cages that permit physical restraint of the animal before handling.

Since HVP-2 appears to be most closely related to SA8 (4), its complete genomic sequence is useful in the study of the evolution of alphaherpesviruses, as well as for determining areas in the genome that may be important for pathogenesis, by comparison with related viruses. Around day 31 after TBI, during the recovery phase, this macaque presented with reduced appetite, difficulty in breathing, lethargy, ataxia, and a generalized skin rash. Infected monkeys often have no or very mild symptoms, although oral and genital lesions may develop. The conserved UL24 family of human alpha, beta and gamma herpesviruses induces a cell cycle arrest at G2/M transition through inactivation of the host cyclinB/cdc2 complex. In this overview we review the natural history of BV in macaques, summarize what is known about the virus at the molecular level, and relate this information to problems associated with diagnosis of BV infections and development of BV-free macaque colonies.
