RESUMEN

Current cross-sectional study was carried out between September 2019 to January 2020 at the Department of Pathology, Mardan Medical Complex (MMC), Mardan, and District Headquarter Hospital North Waziristan, Khyber Pakhtunkhwa (KP), Pakistan. The objectives of the current study were to determine the prevalence of leishmaniasis and its associated risk factors in selected districts of KP province, Pakistan. Altogether, three hundred and seventy-four (n=374) leishmaniosis patients were included in the current study. Skin specimen from the ulcer border were collected. The slides were stained by Giemsa stain and examined for the presence of amastigote. The prevalence of leishmania infected patients in different region of KP were as follows: North Waziristan region 53.7 (n=201) District Mardan 34.7% (n=130); District Nowshera 6.7% (n=25), District Swabi 1.1% (n=4) and other Districts i.e. Dir, Malakand, Buner and Bajawarr were 3.7% (n=14). The frequency of leishmaniasis were more in male and majority of the infected patients were in the age group of <10 years. Among n=374 patients 95.7% (n= 358) had cutaneous leishmaniasis while 3% (n= 11) had mucocutaneous type of infection and 1.3% (n= 5) patients had both cutaneous and mucocutaneous infection. Upon treatment by Sodium stibogluconate (SSG) 97% (n=362) showed clinical signs of complete or partial recovery of their skin lesions. Conclusively, highest incidence of leishmania infection occurred during short study period and majority of the cases showed positive response to treatment.

RESUMEN

Abstract The present study was conducted to investigate the array of hosts, distribution and to evaluate the toxicity of four insecticides: imidacloprid, fipronil, cypermethrin and chlorpyrifos alone and in combination against 3rd instar maggot and adult stage of fruit fly Bactrocera diversa Coquillett, 1904 (Diptera: Tephritidae) during 2021. B. diversa maggots were found vigorously feeding inside the cucurbit hosts (pumpkin, cucumber, bitter gourd, watermelon, round melon, bottle gourd) collected from different localities of Poonch division of Azad Jammu and Kashmir, Pakistan, and this species is reported for the first time as new record to this region. Susceptibilities of B. diversa to insecticides were evaluated using topical method. Mortality was checked after 3, 6, 8 and 24h of exposure. Cypermethrin was most effective to kill 50% of both larval and adult stage with least LC50 [7.2(1.040±0.214), 17.4(0.748±0.193)], respectively followed by imidacloprid. Imidacloprid most effectively killed 90% of both larval and adult population with least LC90 value [73.2 (3.013±0.708) 16.9 (1.886±0.437)] respectively after 24 hours. Cypermethrin with chlorpyrifos most effectively killed 50 and 90 percent of both larval and adult stage of B. diversa with least LC50 value [11.3 (1.085±0.245), 2.5 (0.759±0.252)] and least LC90 value [171.3 (1.085±0.245), 121.9 (0.759±0.252)], respectively after 24h of exposure. Toxicity of each insecticide increased with exposure for longer time and increased dose. Cypermethrin is suggested as most effective against both larval and adult stages of B. diversa in combination with chlorpyrifos followed by imidacloprid.

O presente estudo foi conduzido para investigar a variedade de hospedeiros, distribuição e avaliar a toxicidade de quatro inseticidas: imidaclopride, fipronil, cipermetrina e clorpirifós isoladamente e em combinação contra larva de 3º ínstar e estágio adulto da mosca-das-frutas Bactrocera diversa Coquillett, 1904 (Diptera: Tephritidae) durante 2021. Larvas de B. diversa foram encontradas se alimentando vigorosamente dentro dos hospedeiros de cucurbitáceas (abóbora, pepino, cabaça amarga, melancia, melão redondo, cabaça) coletados em diferentes localidades da divisão Poonch de Azad Jammu e Caxemira, Paquistão, e essa espécie é relatada pela primeira vez como novo registro para essa região. A suscetibilidade de B. diversa a inseticidas foi avaliada por método tópico. A mortalidade foi verificada após 3, 6, 8 e 24 horas de exposição. A cipermetrina foi mais eficaz para matar 50% do estágio larval e adulto com menos CL50 [7,2(1,040 ± 0,214), 17,4 (0,748±0,193)], respectivamente, seguido por imidaclopride. O imidaclopride matou mais efetivamente 90% da população larval e adulta com o menor valor de LC90 [73,2 (3,013 ± 0,708) 16,9 (1,886 ± 0,437)], respectivamente, após 24 horas. Cipermetrina com clorpirifós matou mais efetivamente 50% e 90% do estágio larval e adulto de B. diversa com valor mínimo de LC50 [11,3 (1,085 ± 0,245), 2,5 (0,759 ± 0,252)] e valor mínimo de LC90 [171,3 (1,085 ± 0,245), 121,9 (0,759 ± 0,252)], respectivamente, após 24 horas de exposição. A toxicidade de cada inseticida aumentou com a exposição por mais tempo e com o aumento da dose. A cipermetrina é sugerida como mais eficaz contra os estágios larval e adulto de B. diversa em combinação com clorpirifós seguido de imidaclopride.

RESUMEN

Frequent outbreaks of avian influenza H9N2 virus in Pakistan revealed that this subtype has become endemic in the poultry industry and, besides economic losses, poses a threat to public health. The present study describes the molecular characterization and pathological alterations in naturally infected broiler chickens with the current H9N2 field strain and their phylogenomic dynamics. In this study, tissue samples (trachea, lung, kidney and intestine) from 100 commercial chicken flocks were collected from July 2018 to August 2019. Samples were subjected to molecular detection, phylogeny and subsequent pathological examination. The complete length of the HA gene was successfully amplified in five samples. Nucleotide sequencing revealed positive samples placed in a clade belonging to the B2 sub-lineage of the G1 genotype and categorized as LPAIV based on the amino acid sequence of the HA gene at the cleavage site (PAKSSR/G). Genetic analysis of the haemagglutinin (HA) gene revealed nt: 80.5%-99.5%; aa: 83.8%-98.9% homology to H9N2 strains reported previously from Pakistan, neighbouring countries, and (A/Quail/Hong Kong/G1/97). Gross lesions include a slight airsacculitis, mild hemorrhages, diffuse congestion and purulent exudate in tracheal mucosa, fibrinonecrotic cast in the trachea lumen and mild pulmonary congestion. Histopathological alterations include sloughing of epithelial cells and infiltration of inflammatory cells in the trachea, mononuclear cells (MNCs) infiltration, pulmonary congestion and exudate in the lumen of parabronchi, peritubular congestion in the kidneys with degeneration of tubular epithelial cells and degenerative changes in the intestinal villi epithelial cells and goblet cell hyperplasia. Immunohistochemistry analysis confirmed the presence of AIVH9N2 antigen in the trachea, lungs, kidney and intestine. Electron microscopy revealed ultrastructural changes in the trachea, including degenerated cilia, mitochondrial swelling and enlarged endoplasmic reticulum. Based on all essential analysis, the present study revealed the distribution of the H9N2 virus of G1 genotype in Punjab, Pakistan, with mild to moderate pathogenicity.

Surtos frequentes do vírus da gripe aviária H9N2 no Paquistão revelaram que esse subtipo se tornou endêmico na avicultura e, além das perdas econômicas, representa uma ameaça à saúde pública. O presente estudo descreve a caracterização molecular e as alterações patológicas em frangos de corte naturalmente infectados com a atual cepa H9N2 e sua dinâmica filogenômica. Neste estudo, amostras de tecidos (traqueia, pulmões, rim e intestino) de 100 lotes comerciais de frangos foram coletadas de julho de 2018 a agosto de 2019. As amostras foram submetidas à detecção molecular, filogenia e posterior exame patológico. O comprimento completo do gene HA foi amplificado com sucesso em cinco amostras. O sequenciamento de nucleotídeos revelou amostras positivas colocadas em um clado pertencente à sublinhagem B2 do genótipo G1 e categorizado como LPAIV com base na sequência de aminoácidos do gene da hemaglutinina (HA) no local de clivagem (PAKSSR/G). A análise genética do gene da HA revelou: nt = 80,5%-99,5%; aa = 83,8%-98,9% de homologia com cepas de H9N2 relatadas anteriormente no Paquistão e em países vizinhos (A/Quail/Hong Kong/G1/97). As lesões macroscópicas incluíram aerossaculite leve, hemorragias leves, congestão difusa e exsudato purulento na mucosa traqueal, cilindro fibrinonecrótico no lúmen da traqueia e congestão pulmonar leve. As alterações histopatológicas incluíram descamação de células epiteliais, infiltração de células inflamatórias na traqueia, infiltração de células mononucleares (MNCs), congestão pulmonar e exsudato no lúmen dos parabrônquios, congestão peritubular nos rins com degeneração das células epiteliais tubulares, alterações degenerativas nas células epiteliais das vilosidades intestinais e hiperplasia de células caliciformes. A análise imunoistoquímica confirmou a presença do antígeno AIVH9N2 na traqueia, nos pulmões, no rim e no intestino. A microscopia eletrônica revelou alterações ultraestruturais na traqueia, incluindo cílios degenerados, inchaço mitocondrial e retículo endoplasmático aumentado. Com base em todas as análises, o presente estudo revelou a distribuição do vírus H9N2 do genótipo G1 em Punjab, Paquistão, com patogenicidade de leve a moderada.

RESUMEN

This study aims at reporting the indigenous knowledge of the medicinal flora from the inhabitants of surroundings of the World's largest artificial planted forest "Changa Manga", Pakistan. Data were collected by direct interviews and group meetings from 81 inhabitants including 32 local healers having information regarding the use of indigenous medicinal plants over a period of one year. Different statistical tools were applied to analyze the data including Frequency citation (FC), Relative frequency citation (RFC), Use Value, Factor of informants consensus and fidelity level. This study reported 73 plant species belonging to 37 plant families and 46 genera. The majority of plant species belong to compositae family. The most commonly used medicinal plants were P. hysterophorus L., P. dactylifera L., S. indicum L, P. harmala L., P. emblica L., and A. indica A.Juss. The greatest number of species was used to cure gastrointestinal disorders. The highest fidelity level (68.18%) was of E. helioscopia to cure gastrointestinal disorders. Maximum fresh uses (17) were reported by C. dactylon (L.) Pars. While the highest number of species reporting fresh uses in similar number was 13. In this study, five novel plants are being reported for the first time in Pakistan for their ethnomedicinal worth. Our data reflect unique usage of the medicinal plants in the study area. The statistical tools used in the study proved useful in pointing the most important and disease category specific plants. High use value plant and the new reported medicinal plants might prove an important source of the isolation of pharmacologically active compounds.

RESUMEN

Abstract The red fox (Vulpes vulpes) is a medium-sized carnivore that occurs in different regions of Pakistan, however, still lacks scientific data on its ecology and distribution. The current study investigated the phylogenetic status and diet of the red fox (V.v. griffithii) occurring in Ayubia National Park, Pakistan. Through camera trapping and molecular analysis, we confirmed the occurrence of red fox in the study area. Based on mitochondrial cytochrome B (304 bp) and limited sampling, nearly all red foxes of Ayubia National Park and surrounding Himalayan ranges fall within Holarctic maternal lineage, whereas red foxes found in plains of Pakistan are part of the basal Palearctic maternal lineage. Using 32 scats, we found that red fox diet comprises of 80% animal-based prey species (both wild and domestic) and 19% plant matter. The wild animal prey species included Cape hare (Lepus capensis) and flying squirrel (Pteromyini sp.), which constituted 17% and 15% of diet, respectively. Red foxes infrequently consumed House mouse (Mus musculus), Himalayan Palm civet (Paguma larvata) and sheep (Ovis aries), each comprising around 6% to 9% of red fox diet. The fox species also scavenged on domestic donkey opportunistically. Based on our sampling, our study suggests that the red fox (V.v. griffithii) that occurs in Ayubia National Park and across the lesser Himalayan ranges belongs to Holarctic maternal lineage. The study also highlights consumption of plant seeds by red foxes, indicating it may play an important ecological role in seed dispersal in Ayubia National Park.

Resumo A raposa-vermelha (Vulpes vulpes) é um carnívoro de médio porte que ocorre em diferentes regiões do Paquistão, porém ainda carece de dados científicos sobre sua ecologia e distribuição. O presente estudo investigou o status filogenético e a dieta da raposa-vermelha (V.v. griffithii) que ocorre no Parque Nacional de Ayubia, Paquistão. Por meio de armadilhas fotográficas e análises moleculares, confirmamos a ocorrência de raposa-vermelha na área de estudo. Com base no citocromo B mitocondrial (304 bp) e amostragem limitada, quase todas as raposas-vermelhas do Parque Nacional de Ayubia e áreas circundantes do Himalaia se enquadram na linhagem materna holártica, enquanto as raposas-vermelhas encontradas nas planícies do Paquistão fazem parte da linhagem materna basal paleártica. Usando 32 fezes, descobrimos que a dieta da raposa-vermelha compreende 80% de espécies de presas de origem animal (selvagens e domésticas) e 19% de matéria vegetal. As espécies de presas de animais selvagens incluíram a lebre-do-cabo (Lepus capensis) e o esquilo-voador (Pteromyini sp.), que constituíram 17% e 15% da dieta, respectivamente. As raposas-vermelhas consumiam raramente ratos domésticos (Mus musculus), algas do Himalaia (Paguma larvata) e ovelhas (Ovis aries), cada um compreendendo cerca de 6% a 9% da dieta da raposa-vermelha. A espécie de raposa também se alimentava de burros domésticos de forma oportunista. Com base em nossa amostragem, nosso estudo sugere que a raposa-vermelha (V.v. griffithii) que ocorre no Parque Nacional de Ayubia e nas cordilheiras menores do Himalaia pertence à linhagem materna holártica. O estudo também destaca o consumo de sementes de plantas por raposas-vermelhas, indicando que pode desempenhar um papel ecológico importante na dispersão de sementes no Parque Nacional de Ayubia.

RESUMEN

The Indian Crested Porcupine (Hystrix indica) is classified as an agricultural pest species. It feeds on plants and crops; hence, it is responsible for massive financial losses worldwide. The current study was conducted to assess the diet composition of Indian Crested Porcupine in District Bagh, Azad Jammu and Kashmir (AJ&K). Thus, fecal samples were collected and examined from different sampling sites. Reference slides of the material collected from the study area were prepared for identification of dietary components in fecal pellets. A total of 80 fecal samples were collected and processed. Percent relative frequencies (P.R.F.) were calculated for each plant species recovered from pellets. Data revealed that Indian Crested Porcupine consumed 31 plant species in its diet, among them Zea mays (34.31±7.76) was the most frequently selected species followed by Rumex obtusifolius (15.32±2.57) and Melia azedarach (12.83±4.79). The study revealed that the greatest diversity of (n=20) plant species were consumed in summer season while minimum (n=13) species were used during winter. Among the parts of plants, stem was highly consumed in spring (57.2%) as compared to seed in fall (36.7%) while spikes and leaf were the least recovered parts from the fecal matter. The Berger-Parker diversity index showed highly diversified food (10.92) in the summer time of the year as compared to the autumn season (2.95). This study provides a baseline for the diet preference of this pest in the study area. Based on current findings, a detailed investigation on damage assessment, exploration, habitat use and management of Indian Crested Porcupine in AJ&K has been recommended.(AU)

O porco-espinho de crista indiano (Hystrix indica) é classificado como uma espécie de praga agrícola. Alimenta-se de plantas e colheitas; portanto, é responsável por enormes perdas financeiras em todo o mundo. O estudo atual foi realizado para avaliar a composição da dieta do porco-espinho de crista indiano nos distritos de Bagh, Azad Jammu e Caxemira (AJ&K). Assim, amostras fecais foram coletadas e examinadas em diferentes locais de amostragem. Lâminas de referência do material coletado na área de estudo foram preparadas para identificação dos componentes da dieta em pellets fecais. Um total de 80 amostras fecais foi coletado e processado. As frequências relativas percentuais (P.R.F.) foram calculadas para cada espécie de planta recuperada de pelotas. Os dados revelaram que o porco-espinho indiano consumiu 31 espécies de plantas em sua dieta, entre elas Zea mays (34,31 ± 7,76) foi a espécie mais selecionada, seguida por Rumex obtusifolius (15,32 ± 2,57) e Melia azedarach (12,83 ± 4,79). O estudo revelou que a maior diversidade de (n = 20) espécies de plantas foi consumida no verão, enquanto o mínimo (n = 13) espécies foi utilizado durante o inverno. Entre as partes das plantas, o caule foi muito consumido na primavera (57,2%) em relação à semente no outono (36,7%), enquanto a espiga e a folha foram as partes menos recuperadas da matéria fecal., O índice de diversidade de Berger-Parker mostrou alimentos altamente diversificados (10,92) no verão do ano em comparação com o outono (2,95). Este estudo fornece uma linha de base para a preferência alimentar dessa praga na área de estudo. Com base nas descobertas atuais, uma investigação detalhada sobre avaliação de danos, exploração, uso de habitat e gerenciamento de porco-espinho de crista indiano em AJ&K foi recomendada.(AU)

RESUMEN

Abstract The Indian Crested Porcupine (Hystrix indica) is classified as an agricultural pest species. It feeds on plants and crops; hence, it is responsible for massive financial losses worldwide. The current study was conducted to assess the diet composition of Indian Crested Porcupine in District Bagh, Azad Jammu and Kashmir (AJ&K). Thus, fecal samples were collected and examined from different sampling sites. Reference slides of the material collected from the study area were prepared for identification of dietary components in fecal pellets. A total of 80 fecal samples were collected and processed. Percent relative frequencies (P.R.F.) were calculated for each plant species recovered from pellets. Data revealed that Indian Crested Porcupine consumed 31 plant species in its diet, among them Zea mays (34.31±7.76) was the most frequently selected species followed by Rumex obtusifolius (15.32±2.57) and Melia azedarach (12.83±4.79). The study revealed that the greatest diversity of (n=20) plant species were consumed in summer season while minimum (n=13) species were used during winter. Among the parts of plants, stem was highly consumed in spring (57.2%) as compared to seed in fall (36.7%) while spikes and leaf were the least recovered parts from the fecal matter. The Berger-Parker diversity index showed highly diversified food (10.92) in the summer time of the year as compared to the autumn season (2.95). This study provides a baseline for the diet preference of this pest in the study area. Based on current findings, a detailed investigation on damage assessment, exploration, habitat use and management of Indian Crested Porcupine in AJ&K has been recommended.

Resumo O porco-espinho de crista indiano (Hystrix indica) é classificado como uma espécie de praga agrícola. Alimenta-se de plantas e colheitas; portanto, é responsável por enormes perdas financeiras em todo o mundo. O estudo atual foi realizado para avaliar a composição da dieta do porco-espinho de crista indiano nos distritos de Bagh, Azad Jammu e Caxemira (AJ&K). Assim, amostras fecais foram coletadas e examinadas em diferentes locais de amostragem.
