Some aspects of the biology of Trypauchen vagina Bloch and Schneider of Bombay coast

Morphometrics of 14 metric and 6 meristic characters of Trypauchen vagina of Bombay coast is presented. Number of spines and rays of dorsal, anal and pectoral fins differ with earlier studies. Sexual dimorphism in the length of caudal and anal fins was observed. Length weight relationship of males and females have been worked out to be W = 0.00000 687L super(2.8440) and W = 0.00000 2747L super(3.0274) respectively. The fish is a prolific breeder and peak breeding activity occurs in December. The growth rate was found to be 15.20 mm/month.

Nematode neuropeptide modulation of the vagina vera of Ascaris suum: in vitro effects of PF1, PF2, PF4, AF3 and AF4

Ascaris suum possesses a large number of FMRFamide-related peptides (FaRPs) of which KNEFIRFamide (AF1), KHEYLRFamide (AF2) and KSAYMRFamide (AF8/PF3) have been shown to modulate the intrinsic, rhythmic activity of the vagina vera of A. suum in vitro. In the present study, the effects of the nematode FaRPs, SDPNFLRFamide (PF1), SADPNFLREamide (PF2) and KPNFIRFamide (PF4) (from Panagrellus redivivus) and AVPGVLRFamide (AF3) and GDVPGVLRFamide (AF4) (from A. suum) on the in vitro activity of the vagina vera were examined. The effects of each of the peptides were qualitatively and quantitatively distinct. All 3 FaRPs from P. redivivus were inhibitory, causing a cessation of contractions. PF2 was 3 times more potent than PF1, with a threshold of 1 nM. Although PF4 was the least potent (threshold, 10 nM), its effects at greater than or equal to 10 nM were quantitatively the greatest. Both AF3 and AF4 (1 mu M) induced complex, multiphasic responses consisting of an initial contraction and spastic paralysis followed by a return of contractile activity of increased amplitude. AF3 was 3 times more potent than AF4. The effects of these peptides had some similarities to those observed on A. suum somatic body wall muscle in vitro, with PF1, PF2 and PF4 being inhibitory and AF3 and AF4 being excitatory.

Modulation of the motility of the vagina vera of Ascaris suum in vitro by FMRFamide-related peptides

Ascaris suum contains a large number of FMRFamide-related peptides (FaRPs) of which KNEFIRFamide (AF1), KHEYLRFamide (AF2) and KSAYMRFamide (AF8, also called PF3) have been extensively studied and are known to exert actions on somatic muscle strips of the worm. In the present study, the effects of AF1, AF2 and AF8 on the activity of the vagina vera of female A. suum have been examined in vitro. The vagina vera is a muscular tube connecting the uterus and vagina uteri to the gonopore and is probably involved in regulating egg output. The tissue exhibited spontaneous, rhythmic contractions in vitro, which were modulated by each of the FaRPs tested. The effects of each of the peptides were qualitatively and quantitatively different, and in each case were reversible. AF1 (1 mu M) caused a biphasic response in the form of a transient lengthening of the preparation, followed by a shortening; contractions were initially inhibited but resumed 5 min post-addition of the peptide. Lower concentrations (less than or equal to 0.1 mu M) induced a less marked effect, with rhythmic contractions returning 5 min post-addition. AF2 and AF8 reduced contraction frequency at concentrations greater than or equal to 0.1 mu M. Both peptides also caused the tissue to shorten, although the effects of AF8 on baseline tension were inconsistent. The apparent potencies of AF1 and AF8 on contraction frequency of the vagina vera were 10-fold greater than AF2 and, unlike their actions on A. suum somatic body wall muscles, the actions of AF1 and AF2 were qualitatively different. Indeed, the effects of each of these FaRPs on the vagina vera were markedly different from those observed on the somatic muscle.

Actinomyces coleocanis sp. nov., from the vagina of a dog

A hitherto undescribed Actinomyces-like bacterium was isolated from the vagina of a dog. Biochemical testing and PAGE analysis of whole-cell proteins indicated that the isolate was phenotypically different from previously described Actinomyces species and related taxa. Sequencing of 165 rRNA showed that the unknown bacterium was distinct from all currently known Actinomyces species. Phylogenetically, the unidentified organism displayed a specific association with Actinomyces europaeus, but a sequence divergence of > 5% demonstrated that it represents a distinct species. Based on both phenotypic and 165 rRNA sequence considerations, it is proposed that the unknown strain from a dog be classified as a novel species, Actinomyces coleocanis sp. nov. The type strain is CCUG 41708T (= CIP 106873T).

Arcanobacterium hippocoleae sp. nov., from the vagina of a horse

A polyphasic taxonomic study was performed on a previously unidentified gram-positive, facultatively anaerobic, diphtheroid-shaped organism isolated from a vaginal discharge of a horse. Comparative 16S rRNA gene sequencing demonstrated that the strain was a member of the genus Arcanobacterium, but sequence divergence values of >4% with described species of this genus (viz: Arcanobacterium haemolyticum, Arcanobacterium bernardiae, Arcanobacterium phocae, Arcanobacterium pluranimalium and Arcanobacterium pyogenes) demonstrated that the isolate represented a novel species. The unknown bacterium was readily distinguished from other Arcanobacterium species by biochemical tests. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified as Arcanobacterium hippocoleae sp. nov. The type strain of A. hippocoleae is CCUG 44697T (= CIP 106850T).

Linfoma primário da vagina – revisão da literatura a propósito de um caso clínico

Os tumores primários malignos da vagina são raros, contribuindo apenas para cerca de 1%-2% dos cancros ginecológicos. O linfoma não-Hodgkin (LNH) primário da vagina é raríssimo (existindo aproximadamente 100 casos descritos na literatura). A sua associação com infecção pelo vírus Epstein Barr (VEB) foi descrita em escassos casos. Os autores pretendem fazer uma revisão da literatura de linfoma primário da vagina, com base num caso clínico de LNH-B de grandes células numa mulher nulípara de 25 anos de idade.
