“…He transmitted it by intraperitoneal or intravenous inoculation of peritoneal fluid from acutely ill animals or by trophozoites from cysts of chronically affected animals to white mice, rats, hamsters, voles (Microtiis), ground squirrels (Citellus) and chicken embryos, but not to guinea pigs, rabbits, the ox, rhesus monkey, baby chick, canary or pigeon (Frenkel, 1956a). Jellison, Fullerton and Parker (1956) transmitted it to mice by feeding trophozoites from cysts or peritoneal fluid of affected animals.…”

A disease which is common to man and lower animals is known as a zoo)iosis. Zoonoses were redefined in 1958 by the Joint WHO FAO Expert Committee on Zoonoses as "those diseases and infections which are naturally transmitted between vertebrate animals and man" (World Health Organization, 1959). Less than 20 years ago it was said that there were 50 zoonoses, but in the above report the World Health Organization listed more in connection with vector-borne diseases, altho it need not be restricted to them. epidemiology, taxonomy, evolution, etc.(see ). A dei)ie is a natural population within a species. It lies more or less below the subspecies level, but it is not a formal taxon and is not given a Latin name. There are different types of deme. Nosodemes differ in their clinical manifestations. One example is Leishmania donovani, which has five nosodemes, Indian, Mediterranean, Sudanese, Chinese and South American, which produce different types of disease. Serodemes differ serologically. These are best known among the bacteria and viruses, but also occur among the animal parasites. Tritrichonionas foetus, for example, has several serological types or serodemes. were markedly resistant to infection with Ostertagia circunicincta. while Rambouillets were less so and Southdowns, Shropshires and Hampshires were least resistant.Certain individuals among the more susceptible breeds, however, were just as resistant as the Romneys. Whitlock(1958) has studied genetic resistance to trichostrongylidosis in sheep in some detail.The nutritional status of the host may affect its resistance. Poorly nourished animals are usually more susceptible to infection and suffer more severely from its effects.Protein depletion or protein starvation is particularly important. Lack of specific vitamins and minerals generally decreases resistance, but there are cases in which lack of a certain vitamin which the parasite requires may affect the parasite adversely. Thus, Becker and Smith (1942) found that when calcium pantothenate was added to a ration containing restricted vitamins B,, Bg and pantothenate, the number of oocysts produced hy Einteria nieschulzi infections in the rat was increased.

“…Perhap infeotive stages are ingested by the host rather than trmsmitted by blood contamination from a blood-sucking arthropod. Using mice, Jellison et al (8) found that both cystic and proliferative stages from mice can produce experimental infections when given by mouth. Another possibility is that both blood transmission and ingestion are natural methods of transmission.…”

SYNOPSIS. In heavily endemic collecting sites in Panamá and Colón Provinces, Republic of Panama, 14.7% of Ameiva ameiva and 8.5% of Basiliscus basiliscus were injected with Besnoitia darlingi. Single infected specimens of A. leptophrys and A. festiva were also taken, these being new host species records for this parasite. Infections were found only in the older lizards. Initially, virulence of the lizard parasites for white mice was low but increased with successive mouse passages. Concomitantly, the cyst‐forming capacity of the strain diminished with successive mouse passages. No relation between initial virulence of the lizard parasites for mice and subsequent virulence after 16 or 17 mouse passages was recorded. The original description of B. panamensis (a synonym of B. darlingi) is emended on the basis of extensive material to include cyst diameters of 200–500 μ; also, the liver, mesentery, and tunica propria of the testis occasionally contain cysts. Cysts are frequently macroscopic and on the surface of organs so that they can be seen on casual inspection. B. sauriana Garnham, 1966 is a synonym of B. darlingi.

“…is not known. Oral transmission of B. jellisoni was accomplished in mice by JELLISON et al [9]; they suggested that natural transmission may occur by ingestion. The role of blood-sucking insects either as mechanical vectors or as intermediate hosts in the life cycle has also been postulated [4,12,14,151.…”

Abstract.Besnoitia bennefti infection was detected in two Mexican burros from a closed herd of 15 animals in Maryland. Cystic stages, which were about 1.0 mm in diameter, were found in the testicle of a male and in the skin of the perineum and teat of a female.The superficial location of the cysts on the teat suggests the potential for traumatic rupture and oral transmission during nursing by a foal. The wall of the cysts was 10-1 5 pm thick and consisted of four layers, the outer of which was birefringent. Within each cyst was a mass of organisms each about 1-2 by 5 pm. Various histochemical stains were used. This is the first confirmed diagnosis and report of natural infection with B. bennetfi originating within the United States.Besnoitiosis is a parasitic disease of various domestic and wild animals caused by Toxoplasma-like protozoan organisms. There are many synonyms for the condition in the literature, and there has been some disagreement concerning the nomenclature of the causative organism. JELLISON [8] and POLS [12] have dwelt extensively with this question, and it will not be pursued here. Presently the preferred genus name of the causative organism is Besnoitia.Five different species have been described. B. besnoiti has been found in cattle, blue wildebeest, impala and a kudu [I, 3, 11, 121
