Phylogenetic analyses of bat-associated bugs (Hemiptera: Cimicidae: Cimicinae and Cacodminae) indicate two new species close to Cimex lectularius

Abstract Background Bats are regarded as the primary (ancestral) hosts of bugs of the family Cimicidae. The historically and economically most important species in the family is the common bedbug (Cimex lectularius), because of its worldwide occurrence and association with humans. This molecular-phylogenetic study was initiated in order to expand the knowledge on the phylogeny of cimicid bugs of bats, by investigating samples from Hungary, Romania (representing central-eastern Europe) and two further countries (South Africa and Vietnam). Results Altogether 216 cimicid bugs were collected (73 Ci. lectularius, 133 Ci. pipistrelli, nine Cacodmus ignotus and one Ca. sparsilis). Members of the Cimex lectularius species group were found both in the environment of bats (only Myotis emarginatus, which is a cave/attic-dwelling species) and on three crevice-dwelling bat species (two pipistrelloid bats and M. bechsteinii). On the other hand, Ci. pipistrelli always occurred off-host (near M. myotis/blythii, which are cave/attic-dwelling species). In addition, two Cacodmus spp. were collected from Pipistrellus hesperidus. The morphological characters of these specimens are illustrated with high resolution pictures. Analysis of cytochrome c oxidase subunit 1 (cox1) sequences generated from 38 samples indicated relative genetic homogeneity of Ci. pipistrelli, while the Ci. lectularius group had two haplotypes (collected from pipistrelloid bats in Hungary and Vietnam) highly divergent from other members of this species group. These results were confirmed with molecular and phylogenetic analyses based on the internal transcribed spacer 2 (ITS2). Bat-associated bugs morphologically identified as Ca. ignotus and Ca. sparsilis were different in their cox1, but identical in their ITS2 sequences. Conclusions Molecular evidence is provided here on the existence of two new genotypes, most likely new species, within the Ci. lectularius species group. The relevant specimens (unlike the others) were collected from pipistrelloid bats, therefore the association of Ci. lectularius with different bat host species (pipistrelloid vs myotine bats) should be evaluated further as a possible background factor of this genetic divergence. In addition, Ca. ignotus is reported for the first time in South Africa

Study of possibilities of replacement of fish meal by poultry by product in formulated diet of Huso huso

To regard to dramatic decreasing of pelagic fish and depending on fish meal for sturgeon Feeding a project with title on "Study of possibility of replacement of fish meal by poultry by product in formulated diet of Huso huso" in two faz (fingerling) and (Growth out) were carried out. In first faz, proximate composition of fish meal, poultry by product and diet ingredient were determined , thereafter Six test diets (contain 45% protein and 19 Mj kg^-1 energy) were prepared based on anchovy fish meal and poultry by-product substituted at levels of 20% (PBM_20), 40% (PBM_40), 60% (PBM_60), 80% (PBM_80) and 100% (PBM_100), respectively. Huso huso Fingerlings (28.42±0.17gr ± SD) were stocked in 18 fiberglass tanks and fed to satiation to eight week. Result indicated the highest final weight (FW), Weight gain (WG), Specific growth rate (SGR) and Protein efficiency ratio (PER) were belonged to control diet (350.52 ±21.86_gr),(1133.00 ±74.84%),(3.74±0.092 %per day) and (1.58 ±0.017) respectively. But No significant difference was detected between FM, PBM_20, PBM_40 and PBM_60 (P>0.05), Also, there were not significant difference in treatments for Feed efficiency Ratio between (PBM_0), (PBM_20), (PBM_40), (PBM_60) (PBM_80) respectively (P0.05).The best feed efficiency ratio belonged to fish fed PBM_40 that no significant differences with (PBM_20), (PBM_60) and (PBM_80) (P>0.05).a significant decrease of body lipid observed by increasing of supplementation of poultry by product in diets that lowest body lipid (6.6±0.16) were stabilized in (PBM_80) (P0.05). also hepatosomatc index were significantly increase by increasing of poultry by product in diets respectively that highest were observed in fish fed PBM100 (4.2±0.63) (P<0.05).Result of this investigation indicated that poultry by product had high potential for replacing of fish meal in fingerling and growth out Huso huso diet. Therefore suggested a investigation design for research about the effect of poultry by product on growth rate, body composition and immune system of Huso huso at long period for introduce a new replacer product Instead Of fish meal in sturgeon aquaculture industry

Screening for <i>Hepatozoon</i> parasites in gerbils and potential predators in South Africa

Samples of gerbils and their potential predators were screened for the presence of Hepatozoon parasites (Apicomplexa: Adeleorina) using both microscopic examination and sequencing of partial 18S rRNA sequences. Positive samples were compared to published sequences in a phylogenetic framework. The results indicate that genets can be infected with Hepatozoon felis. A Cape fox was infected with Hepatozoon canis, whereas the sequence from an infected rodent fell within a group of parasites primarily recovered from other rodents and snakes
