“…Several studies of the prevalence of toxoplasmosis in Sri Lanka (formerly Ceylon) have been published: the presence of anti-T. gondii antibodies was reported in rodents (106), dogs, cats (107) and humans (108). Other studies (109,110,111,112,113,114,115,116,117,118,119,120,121,122,123) of the seroprevalence of toxoplasmosis in various species in Afghanistan, Bhutan, Nepal, Maldives and Sri Lanka are summarised in Table IV.…”

Toxoplasmosis, a cosmopolitan zoonosis, is caused by an apicomplexan, obligate, intracellular protozoan parasite, Toxoplasma gondii. Nearly all animals, including humans, are at risk owing to its broad geographical distribution. The authors searched published data related to T. gondii in databases, including Google Scholar, PubMed and Science Direct for South Asian countries, and retrieved a total of 113 articles fulfilling the criterion of seroprevalence investigation. Toxoplasma gondii infection in livestock and humans was investigated using various serological tests. In these studies, a total of 14,431 samples from domestic animals and 53,899 samples from humans were screened for anti-T. gondii antibodies in all South Asian countries. Among the animals, cattle (n = 1,981), goats (n = 3,285), buffaloes (n = 1,695), sheep (n = 1,747), cats (n = 1,480), camels (n = 435), elephants (n = 45), pigs (n = 920), dogs (n = 1,604) and poultry (n = 1,206) were tested. This comprehensive review will be useful to biologists, public health workers, physicians and veterinarians and provides a better understanding of the distribution of T. gondii in this region. Furthermore, this knowledge will support efforts to find and apply effective prevention measures to better manage this zoonosis in South Asian countries.

A Preliminary Analysis of the Immunoglobulin Genes in the African Elephant (Loxodonta africana)

et al. 2011

The genomic organization of the IgH (Immunoglobulin heavy chain), Igκ (Immunoglobulin kappa chain), and Igλ (Immunoglobulin lambda chain) loci in the African elephant (Loxodonta africana) was annotated using available genome data. The elephant IgH locus on scaffold 57 spans over 2,974 kb, and consists of at least 112 VH gene segments, 87 DH gene segments (the largest number in mammals examined so far), six JH gene segments, a single μ, a δ remnant, and eight γ genes (α and ε genes are missing, most likely due to sequence gaps). The Igκ locus, found on three scaffolds (202, 50 and 86), contains a total of 153 Vκ gene segments, three Jκ segments, and a single Cκ gene. Two different transcriptional orientations were determined for these Vκ gene segments. In contrast, the Igλ locus on scaffold 68 includes 15 Vλ gene segments, all with the same transcriptional polarity as the downstream Jλ-Cλ cluster. These data suggest that the elephant immunoglobulin gene repertoire is highly diverse and complex. Our results provide insights into the immunoglobulin genes in a placental mammal that is evolutionarily distant from humans, mice, and domestic animals.

“…Intermediate hosts are probably all warm-blooded species, including most farm animal species as well as humans. Definitive hosts are represented by members of the feline family, especially the domestic cat (Johnson 1997;Garcia et al 2005;Dangolla et al 2006;Figueroa-Castillo et al 2006;Mucker et al 2006;Ryser-Degiorgis et al 2006;Ghazy et al 2007).…”

“…Tissue cysts of T. gondii from deer or other wildlife, including rabbit, wild buffalo, other deer, kangaroos and bears are considered sources of infection for humans (Zarnke et al 1997;Martinez-Carasco et al 2004;Dangolla et al 2006). Hunters and their families can also become infected during the evisceration of animals and the cutting of game.…”
