4 2. LITERATURE REVIEW 2.1 Lymphatic Filariasis Lymphatic
2. LITERATURE REVIEW 2.1 Lymphatic filariasis Lymphatic filariasis is an inflammatory parasitic infection of lymphatic vessels caused by the filarial roundworms Wuchereria bancrofti, Brugia malayi, and Brugia timori, which results in massive lymphoedema (elephantiasis) of the affected tissues. The adult worms inhabit the lymphatics where they elicit an inflammatory response that causes acute lymphangitis and eventualy lymphatic obstruction leading to severe lymphoedema. 2.1.1 Epidemiology WHO (1995) reported that lymphatic filariasis is widespread throughout the tropical and subtropical areas of Asia, Africa, the Western Pacific and some parts of the America. More than 1.1 thousand million people (20% of the world’s population) now live in areas where they are at risk of infection with lymphatic filarial parasites and a minimum of 120 million people is currently infected (about 107 million with W. bancrofti and 13 million with B. malayi or B. timori). A total of 44 million persons currently suffer from one or more of the overt manifestations of the infection: lymphoedema and elephantiasis of the limbs or genitals, hydrocele, chyluria, pneumonitis, or recurrent infections associated with damaged lymphatic vessels. The remainder of the 120 million infected has “preclinical” hidden damage of their lymphatic and renal systems. 2.1.1.1. Geographical distribution Lymphatic filariasis is known to occur in 73 countries (Figure 1); 38 in the Africa region, 7 in the region of the America, 4 in the Eastern Mediterranean region, 8 in the South-East Asia region and 16 in the Western Pacific region. The condition has been previously reported, and might still 4 5 occur in another 40 countries. -

The examined nematodes are predominantly parasites of fishes. Their analyses provided well-supported trees allowing the study of phylogenetic relationships among some spirurine nematodes. The present results support the placement of Cucullanidae at the base of the suborder Spirurina and, based on the position of the genus Philonema (subfamily Philoneminae) forming a sister group to Skrjabillanidae (thus Philoneminae should be elevated to Philonemidae), the paraphyly of the Philometridae. Comparison of a large number of sequences of representatives of the latter family supports the paraphyly of the genera Philometra, Philometroides and Dentiphilometra. The validity of the newly included genera Afrophilometra and Carangi- nema is not supported. These results indicate geographical isolation has not been the cause of speciation in this parasite group and no coevolution with fish hosts is apparent. On the contrary, the group of South-American species ofAlinema , Nilonema and Rumai is placed in an independent branch, thus markedly separated from other family members. -
A Review of Longnose Skates Zearaja Chilensisand Dipturus Trachyderma (Rajiformes: Rajidae)
Univ. Sci. 2015, Vol. 20 (3): 321-359 doi: 10.11144/Javeriana.SC20-3.arol Freely available on line REVIEW ARTICLE A review of longnose skates Zearaja chilensis and Dipturus trachyderma (Rajiformes: Rajidae) Carolina Vargas-Caro1 , Carlos Bustamante1, Julio Lamilla2 , Michael B. Bennett1 Abstract Longnose skates may have a high intrinsic vulnerability among fishes due to their large body size, slow growth rates and relatively low fecundity, and their exploitation as fisheries target-species places their populations under considerable pressure. These skates are found circumglobally in subtropical and temperate coastal waters. Although longnose skates have been recorded for over 150 years in South America, the ability to assess the status of these species is still compromised by critical knowledge gaps. Based on a review of 185 publications, a comparative synthesis of the biology and ecology was conducted on two commercially important elasmobranchs in South American waters, the yellownose skate Zearaja chilensis and the roughskin skate Dipturus trachyderma; in order to examine and compare their taxonomy, distribution, fisheries, feeding habitats, reproduction, growth and longevity. There has been a marked increase in the number of published studies for both species since 2000, and especially after 2005, although some research topics remain poorly understood. Considering the external morphological similarities of longnose skates, especially when juvenile, and the potential niche overlap in both, depth and latitude it is recommended that reproductive seasonality, connectivity and population structure be assessed to ensure their long-term sustainability. Keywords: conservation biology; fishery; roughskin skate; South America; yellownose skate Introduction Edited by Juan Carlos Salcedo-Reyes & Andrés Felipe Navia Global threats to sharks, skates and rays have been 1. -

Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, Leninskii Prospect, 33, Moscow, 119071, Russia e-mail: [email protected] Accepted for publication 12 September 2019 Summary. The nematode Comephoronema werestschagini (Chromadorea: Cystidocolidae) is redescribed from the Baikal yellowfin Cottocomephorus grewingkii (Dybowski, 1874). Important morphological features, such as the presence of four submedian cephalic papillae, four well developed bilobed sublabia, two large lateral pseudolabia, pairs of rounded deirids, as well as the position of phasmids are reported for the first time in this species. The SSU rDNA-based phylogeny of the cystidicolids is defined according to the sequences obtained for C. werestschagini, C. oshmarini and Capillospirura ovotrichuria. The polyphyly of the Cystidocolidae is herein confirmed. All three studied species appear as members of Cystidicolidae s. str. clade; however, C. werestschagini and C. oshmarini are not phylogenetically related.
