[Ab] Abstract:BACKGROUND: It is generally assumed that hookworm infections in humans are caused by Necator americanus and Ancylostoma duodenale. However, previous studies have also reported the presence of the animal hookworm A. ceylanicum in human stools. METHODS: We determined hookworm infections in children in a tribal community in Tamil Nadu, India, using a semi-nested PCR-RFLP approach. RESULTS: The results indicate that human species account for a majority of the hookworm infections (N. americanus 39/41 [95%]; A. duodenale 6/41 [15%]), whereas the animal hookworm A. ceylanicum only accounts for a minority of the infections (5%; 2/41). CONCLUSIONS: The results emphasize the need to consider zoonotic ancylostomiasis while developing strategies to control hookworm infections.

[Ab] Abstract:We report a patient presenting with chronic diarrhoea of unidentified etiology. Laboratory results showed microcytic anemia, peripheral eosinophilia with negative results of stool sample smears and stool concentration technique. Ancylostoma duodenale was found in the caecum and terminal ileum during colonoscopy. The patient was treated with a 3-day course of 400 mg albendazole and iron supplement. The diarrhoea disappeared shortly after treatment. Physicians particularly in tropical areas should be aware of hookworms as causative agents of chronic diarrhoea and it may be found in the large intestine.

[Ab] Abstract:The objective of this randomized, blinded, placebo controlled laboratory study was to confirm the efficacy of a single oral administration of two marketed formulations of milbemycin oxime (Interceptor(®) Flavor Tabs(®) and Sentinel(®) Flavor Tabs(®)) at a minimum dose of 0.5 mg/kg (0.23 mg/lb) against natural infections of Ancylostoma braziliense in dogs. Thirty-six hookworm infected dogs, a minimum of 10 weeks of age and of various breeds and genders were used. Fecal egg counts were done on three separate days prior to treatment for randomization purposes. Dogs were ranked by descending order of the fecal egg count arithmetic means and randomly assigned to either the two milbemycin treatment groups or the placebo control group in blocks of three dogs each, 12 dogs per group. Dogs were dosed according to the product label with blinding maintained by separation of function. Worm counts were done at necropsy 7 days after treatment. Reduction in A. braziliense worm counts in the milbemycin groups were compared to the placebo control group using analysis of variance of the A. braziliense logarithmic mean worm counts and percent efficacy was based on geometric means. Efficacy was defined as the ability of the test products to significantly (p≤0.05) reduce parasite load by 90% or greater in treated dogs when compared to adequately infected placebo control dogs. The placebo control group had a geometric mean worm count of 19.2. The Interceptor treated group had a geometric mean worm count of 0.38 representing a 98% reduction in parasite load and the Sentinel treated group had a geometric mean worm count of 0.98 representing a 95% reduction in parasite load. Both reductions were highly significant (p<0.0001). In this study, milbemycin oxime, when administered as two marketed formulations at a minimum dose of 0.5 mg/kg (0.23 mg/lb), was efficacious for removing adult A. braziliense in naturally infected dogs.

[Ab] Abstract:Between 1916 and 1923, the Federal District and 11 Brazilian states entered into cooperation agreements with the International Health Board of the Rockefeller Foundation to combat a rural endemic disease, namely ancylostomiasis. This paper presents the diary of Alan Gregg, one of the American physicians who worked in Brazil from 1919 to 1922. An interesting source to discuss issues relating to the history of public health in Brazil, in addition to information about the activities to combat ancylostomiasis developed by the Rockefeller Foundation in the country, the diary of the physician presents his impressions concerning nature, culture, politics and society in Brazil. In the diary excerpts presented here, however, aspects related to the professional activities performed by Gregg are prioritized.

[Ab] Abstract:Laurence Moon Bardet Biedl Syndrome is a rare genetic disorder. Consanguineous marriage is usually the common cause. Principal features of Bardet Biedl Syndrome are red cone dystrophy, obesity, polydactyl, hypogonadism and renal anomalies. The diagnosis was overlooked in our patient until he came in our hospital. We here report an infrequent case of autosomal recessive disorder with Anaemia.

[Ti] Title:The zoonotic risk of Ancylostoma ceylanicum isolated from stray dogs and cats in Guangzhou, South China.

[Ab] Abstract:Canine and feline hookworm infection is endemic in many countries with zoonotic transmission representing a potentially significant public health concern. However, there is limited data available on the zoonotic transmission of canine and feline hookworms in China. This study was conducted to evaluate the zoonotic risk of Ancylostoma ceylanicum isolated from stray dogs and cats in Guangzhou, south China. Primer pairs CAF/CAR were designed to amplify complete ITS sequences of obtained A. ceylanicum. The results were compared with fourteen ITS reference sequences of human-derived A. ceylanicum registered in GenBank, and phylogenetic trees were established by using NJ and ML methods. The sequence similarity of three dog-derived and five cat-derived A. ceylanicum with fourteen human-derived A. ceylanicum were 96.8%~100% and 97.8%~100%, respectively. Phylogenetic analysis placed A. ceylanicum isolated from dogs and cats in the same group with A. ceylanicum human isolates. Due to the ability of A. ceylanicum to cause a patent infection in humans, the zoonotic risk arising from dog and cat reservoirs to communities in this region should be determined.

[Ab] Abstract:Ancylostoma ceylanicum, a hookworm of canids and felids in Asia, is becoming the second most common hookworm infecting humans. In 2012, we investigated the prevalence and infection dynamics of and risk factors for hookworm infections in humans and dogs in a rural Cambodian village. Over 57% of the population was infected with hookworms; of those, 52% harbored A. ceylanicum hookworms. The greatest intensities of A. ceylanicum eggs were in persons 21-30 years of age. Over 90% of dogs also harbored A. ceylanicum hookworms. Characterization of the cytochrome oxidase-1 gene divided isolates of A. ceylanicum hookworms into 2 groups, 1 containing isolates from humans only and the other a mix of isolates from humans and animals. We hypothesize that preventative chemotherapy in the absence of concurrent hygiene and animal health programs may be a factor leading to emergence of A. ceylanicum infections; thus, we advocate for a One Health approach to control this zoonosis.

[Ti] Title:Molecular cloning and analysis of Ancylostoma ceylanicum glutamate-cysteine ligase.

[Ab] Abstract:Glutamate-cysteine ligase (GCL) is a heterodimer enzyme composed of a catalytic subunit (GCLC) and a modifier subunit (GCLM). This enzyme catalyses the synthesis of γ-glutamylcysteine, a precursor of glutathione. cDNAs of the putative glutamate-cysteine ligase catalytic (Ace-GCLC) and modifier subunits (Ace-GCLM) of Ancylostoma ceylanicum were cloned using the RACE-PCR amplification method. The Ace-gclc and Ace-gclm cDNAs encode proteins with 655 and 254 amino acids and calculated molecular masses of 74.76 and 28.51kDa, respectively. The Ace-GCLC amino acid sequence shares about 70% identity and 80% sequence similarity with orthologs in Loa loa, Onchocerca volvulus, Brugia malayi, and Ascaris suum, whereas the Ace-GCLM amino acid sequence has only about 30% sequence identity and 50% similarity to homologous proteins in those species. Real-time PCR analysis of mRNA expression in L3, serum stimulated L3 and adult stages of A. ceylanicum showed the highest level of Ace-GCLC and Ace-GCLM expression occurred in adult worms. No differences were detected among adult hookworms harvested 21 and 35dpi indicating expression of Ace-gclc and Ace-gclm in adult worms is constant during the course of infection. Positive interaction between two subunits of glutamate-cysteine ligase was detected using the yeast two-hybrid system, and by specific enzymatic reaction. Ace-GCL is an intracellular enzyme and is not exposed to the host immune system. Thus, as expected, we did not detect IgG antibodies against Ace-GCLC or Ace-GCLM on days 21, 60 and 120 of A. ceylanicum infection in hamsters. Furthermore, vaccination with one or both antigens did not reduce worm burdens, and resulted in no improvement of clinical parameters (hematocrit and hemoglobin) of infected hamsters. Therefore, due to the significant role of the enzyme in parasite metabolism, our analyses raises hope for the development of a successful new drug against ancylostomiasis based on the specific GCL inhibitor.
