“…The anterior suction disc is circular and may be very prominent or just a minor expansion of the lips of the mouth. The posterior suction disc is circular, directed ventrally, and can be either larger or smaller than the body of the leech (Moser et al 2009). Aquatic leeches that cause parasitic infestation in humans and animals include Limnatis nilotica, Myxobdella africana, Dinobdella ferox, Phytobdella catenifera and Teromyzon tessulatom (Gholami-Ahangaran et al 2012).…”

Leeches are bloodsucking hermaphroditic parasites that attach to tissues using two muscular suckers, ingest large amounts of blood and may cause severe anaemia in the host. Two four-month-old mixed-breed dogs (one bitch and one male) were referred with anorexia, retching, hypersalivation and bleeding from the oral cavity. On physical examination, two live leeches were detected on the ventral aspect of the tongue of the bitch and one in a similar position in the male. The leeches were gently detached and removed using Adson tissue forceps after applying vinegar over the area. Microcytic hypochromic anaemia was detected in the bitch and mild leukocytosis in the dog. One month after treatment both animals were re-examined and a complete blood count was normal. Given that infestation with leeches as described here is associated with contaminated water, the use of clean and safe drinking water is recommended to avoid such diseases.

In this study, the triple jaws and suckers of the leeches belonging to the Hirudo verbana Carena, 1820 (Annelida; Clitellata; Hirudinida) were examined using the stereomicroscopy and scanning electron microscopy. In H. verbana, suckers are seen on the first annulus and last annulus of the body. The mouth opens in the center of the front suction cup, and behind this opening is a movable triple jaw apparatus with many teeth. The posterior sucker disc consists of the last seven body segments and lacks an opening. The shape of the jaw is trignatous. The pharynx is equally located around of the three muscular jaws. The jaws are muscular covered with cuticle and carry a row of teeth arranged at the tip. In this study, it was determined that secretory canal holes were identified between the teeth. The results show that the size of teeth determines long-term bleeding so revealing the structure and working mechanism of the teeth has importance for medicinal leeches. At the same time, the difference of teeth and jaw structures of leeches may be a criterion in the classification of medicinal leeches.

Leeches can parasitize many vertebrate taxa. In amphibians, leech parasitism often has potential detrimental effects including population decline. Most of studies on the host-parasite interactions involving leeches and amphibians focus on freshwater environments, while they are very scarce for terrestrial amphibians. In this work, we studied the relationship between the leech Batracobdella algira and the European terrestrial salamanders of the genus Hydromantes, identifying environmental features related to the presence of the leeches and their possible effects on the hosts. We performed observation throughout Sardinia (Italy), covering the distribution area of all Hydromantes species endemic to this island. From September 2015 to May 2017, we conducted >150 surveys in 26 underground environments, collecting data on 2629 salamanders and 131 leeches. Water hardness was the only environmental feature correlated with the presence of B. algira, linking this leech to active karstic systems. Leeches were more frequently parasitizing salamanders with large body size. Body Condition Index was not significantly different between parasitized and non-parasitized salamanders. Our study shows the importance of abiotic environmental features for host-parasite interactions, and poses new questions on complex interspecific interactions between this ectoparasite and amphibians.
