The toxin content in various life cycle stages of tank-cultivated bullseye puffer (Sphoeroides annulatus) were analyzed by mouse bioassay and ESI-MS spectrometry analysis. The presence of toxin content was determined in extracts of sperm, eggs, embryo, larvae, post-larvae, juvenile, pre-adult, and adult fish, as well as in food items used during the cultivation of the species. Our findings show...

We describe a new species of gekkonid lizard from Palawan Island, southwestern Philippines. The new species differs from all Philippine Cyrtodactylus and all other phenotypically similar Southeast Asian Cyrtodactylus by characteristics of external morphology, color pattern, and body size. The new species is common in lowto mid-elevation primary growth forest and disturbed lowland riparian galle...

background : ticks are blood feeder acarians that feed on variety of animals and introduce a wide variety of molecules to their host immune system and some of them may stimulate host immune system to produce antibodies. this study was carried out to detect humoral immune responses following boophilus annulatus infestation. methods: seven cattle were each experimentally infested with 10000 b. an...

A morphometrics, morphological and molecular study revealed the presence of stunt nematode Tylenchorhynchus annulatus in rhizosphere soil paddy rice corn Central Java, Indonesia. Phylogenetic analysis placed Indonesian populations a clade with from China South Korea, separated USA. To our knowledge this is first report T.

Labidiaster annulatus, Sladen (1889) is a multi-rayed (9–50) voracious Antarctic sea star with numerous large, conspicuous crossed pedicellariae. An active and opportunistic predator, it commonly preys upon euphausiids, amphipods, and small fish in the water column (Dearborn et al. 1991). Labidiaster annulatus is distributed around the Antarctic, Kerguelen, South Orkney, South Sandwich Islands,...

A total number of 450 blood samples were collected from 45 different randomly selected cattle herds. Light microscopic examination of blood smears revealed Babesia spp. infection in 4.2%, while 8.9% of blood samples were positive using PCR. Upon multiplex-PCR (mPCR), B. bigemina and B. bovis infections were detected in 37/40 (92.5%) and 3/40 (7.5%) samples, respective...

The present communication describes the detailed day wise study of histological changes of the ovary of Rhipicephalus (Boophilus) annulatus in the postengorgement period together with the systematic classification of their oocytes. The ovary of R. (B.) annulatus is panoistic type with an asynchronous development of oocytes. All the stages (II, III, IV, and V) of oocytes except stage I were simi...

background: traditionally, morphological features of rhipicephalus (boophilus) annulatus from closely-related ticks have been considered for their identification and differentiation. however, it is difficult and requires expertise in order to accurately identify and differentiate engorged female ticks and some developmental stages such as larva and nymph from other similar ticks. hence, molecul...

background : boophilus annulatus is an obligate blood feeder tick that can cause great losses in animals due to anemia and its ability to injure its host skin directly. the aim of this study was identification of cattle humoral immune response to some tick proteins during experimental infestation. methods : immune sera against tick were collected from experimentally infested cattle with ticks. ...
