1. The tissues of Rous chicken sarcoma and of the infectious myxoma of the rabbit do not possess the oxidation-reduction enzyme succinodehydrogenase, which is present in normal tissues and in transplantable tumors. 2. Filterable virus diseases (rabbit Virus III, rabbit neurovaccine, rabbit herpes, fowl-pox) produce in the tissues affected by them a partial inhibition of succinodehydrogenase.

This article reflects upon the recent return to linear history writing in medical history. It takes as its starting point a critique of the current return to constructivist ideas, suggesting the use of other methodological choices and interpretations to the surviving archival and textural sources of the sixteenth century pox. My investigation analyses the diagnostic act as an effort to bring to...

The second observation was the error made in calculating the positive predictive value. By deÞ nition, positive predictive value is “the probability that a person actually has the disease given that he or she tests positive”.[2] In the paper under discussion, the disease was represented by VZV ELISA positives (as the gold standard) and the test was represented by “recalled history of chicken po...

BACKGROUND Sheeppox (SPP) is one of the priorities, high-impact animal diseases in many developing countries, where live attenuated vaccines are routinely used against sheeppox virus (SPPV). In an event of an SPP outbreak, historically disease-free countries would hesitate to use of live vaccines against SPPVdue to the safety and trade reasons. Currently no killed SPPV vaccines are commercially...

The Varicella Zoster virus persists in sensory nerve ganglion cells after chicken pox and gets reactivated to cause herpes zoster after variable periods of time as a result of waning of specific cellular immunity. Susceptible contacts of herpes zoster can develop chicken pox and very rarely herpes zoster. We report an interesting case of a father and his son who developed herpes zoster simultan...

The fly pharyngeal sense organs lie at the transition between external and internal nutrient-sensing mechanisms. Here we investigate the function of pharyngeal sweet gustatory receptor neurons, demonstrating that they express a subset of the nine previously identified sweet receptors and respond to stimulation with a panel of sweet compounds. We show that pox-neuro (poxn) mutants lacking taste ...

Outbreaks of buffalopox or pox-like infections affecting buffaloes, cows and humans have been recorded in many parts of the world. Since the first outbreak in India, a large number of epidemics have occurred. Unlike in the previous years, generalized forms of the disease are now rare; however, there are severe local forms of the disease affecting the udder and teats, leading to mastitis thereby...

The family Poxviridae consists of large double-stranded DNA containing viruses that replicate exclusively in the cytoplasm of infected cells. Members of the orthopox genus include variola, the causative agent of human small pox, monkeypox, and vaccinia (VAC), the prototypic member of the virus family. Within the relatively large (approximately 200 kb) vaccinia genome, three classes of genes are...

terised in this and in other countries by a striking decrease of small-pox mortality. It must be borne in mind that at the time of the introduction of vaccination a large proportion of the population was protected by previous attacks of small-pox, either natural or inoculated, and that the amount of vaccination adequate to afford a great protection in the earlier years of the century ceased to ...

The article highlights the career of Professor Mansour Ali Haseeb (1910 - 1973; DKSM, Dip Bact, FRCPath, FRCP [Lond]), a pioneer worker in health, medical services, biomedical research and medical education in the Sudan. After his graduation from the Kitchener School of Medicine (renamed, Faculty of Medicine, University of Khartoum [U of K]) in 1934, he devoted his life for the development of l...
